Ranking Factors for Google SERPS

Google uses a minimum of 200 factors to determine the position of a website in the search engine rankings. Many of these factors are - partly - known, because Google itself has communicated about them, for example. Other factors can be added to the list through tests, measurements and comparisons.

Below we list 209 factors that certainly influence the position of a website or page in the Google search engine. Due to - even daily - updates of the Google algorithm, the effect of these factors is variable, but it gives a good picture of what you should pay attention to when optimizing a website's search engine.

Domain Factors

1. Domain Age: in this video Matt Cutts from Google says so:

"The difference between a domain that's six months old versus a year old isn't that big at all."

In other words, they use domain age... but it's not very important.

2. Keyword appears in top domain: this doesn't give it the boost it used to. But having a keyword in your domain still acts as a relevant signal .

3. Keyword first in domain: a domain that starts with their target keyword has a head start on sites that don't have that keyword in their domain (or have the keyword in the middle or end of their domain).

4. Domain registration length: in a Google patent state:

"Valuable (legitimate) domains are often paid for several years in advance, while deportable (invalid) domains are rarely used for more than one year. Therefore, the date on which a domain expires in the future can be used as a factor in predicting the legitimacy of a domain. “

5. Keyword in subdomain: the Moz expert panel agrees that a keyword in the subdomain can improve the ranking.

Page level factors

11. Keyword in title tag: Although it was not so critical if it ever was, your title tag would remain an important SEO- signal on the page .

12. Title tag starts with keyword according to Moz title tags that start with a keyword tend to perform better than title tags that have the keyword at the end of the tag.

13. Keyword in description Tag: Google does not use the meta-description label as a signal for direct classification. However, your description tag may affect the click frequency, which is a key factor.

14. Keyword appears in H1 tag: H1 tags are a "second title tag". Together with your title tag, Google uses your H1 tag as a secondary relevancy signal, according to the results of this correlation study :

15. TF-IDF: A nice way of saying: "How often does a certain word appear in a document?". The more often that word appears on a page, the more likely it is that the page is about that word. Google probably uses an advanced version of TF-IDF.

16. Content length: content with more words can cover a wider width and is probably preferred in the algorithm compared to shorter, superficial articles. In fact, a recent ranking factor study shows that the length of the content correlated to the position of the SERP .


17. Table of contents: the Using a linked table of contents can help Google better understand the content of your page.

18. Keyword density Although not as important as it once was, Google can use it to determine the subject of a web page. But going overboard can hurt you.

19. Latent semantic indexing Keywords in content(LSI): LSI keywords help search engines extract meaning from words that have more than one meaning (for example: Apple, the computer company versus Apple, the fruit). The presence / absence of LSI probably also acts as a content quality signal.

20. LSI keywords in title and description Tags: As with web page content, LSI keywords in page meta tags are likely to help distinguish between words with multiple potential meanings. Can also act as a signal for relevance.

21. Page Layouts Subject Depth: there is a known correlation between the depth of coverage of topics and Google rankings. That's why pages that cover each angle probably have a head start over pages that only partially cover one topic.

22. Page Load speed via HTML: both Google as Bing Use the page loading speed as a ranking factor.Search engine piders can estimate your site speed reasonably accurately based on the HTML code of your page.

23. Page Loading speed via Chrome Google can also use Chrome user data to better cope with the loading time of a page. This way they can measure how fast a page actually loads to users.

24. Use of AMP: although this is not direct Google ranking factor is AMP may be a requirement to classify at the mobile version of the Google News carousel .

25. Entity agreement: the content of a page corresponds to the " entity " what a user is looking for? If so, that page may get a higher position for that keyword.

26. Google Hummingbird: these " algorithm change " has helped Google go beyond keywords. Thanks to Hummingbird, Google can now better understand the subject of a web page.

27. Double content: identical content on the same site (even slightly modified) can increase the visibility of a site's search engine adversely affect .

28. Rel = Canonical: at correct Use of this tag can prevent Google from punishing your site for duplicate content.

29. Image optimization: images send search engines important relevance signals via their filename, alternative text, title, description and caption.

30. Content history: the update of Google Caffeine is in thebenefit from recently published or updated content, especially for time-sensitive searches. To emphasize the importance of this factor, Google shows the date of the last update of a page for certain pages:

31. Magnitude of content updates The importance of treatments and modifications also serves as a freshness factor. Adding or deleting entire sections is more important than changing the order of a few words or correcting a typing error.

32. Historical page updates: How often has the page been updated over time? Daily, weekly, every 5 years? The frequency of page updates also plays a role in freshness.

33. Express keywords when a keyword is displayed in the first 100 words of a page's content, this is linked to the ranking on the first page of Google .

34. Keyword in H2, H3 Tags If your keyword is displayed as a header in H2 or H3 format, this may be another weakly relevant signal. As a matter of fact says Googler John Mueller :
"These heading tags in HTML help us understand the structure of the page."

35. Outgoing connection quality Many SEOs think that linking power positions helps to send signals of trust to Google. And this is supported by a recent industrial research .

36. Outbound Link theme: according to The Hillop Algorithm can Google the content of the pages to which you use link as a relevancy signal. For example, if you have a page about cars that contains links to movie-related pages, this may tell Google that your page is about the movie Cars and not about the car.

37. Grammar and spelling: correct grammar and spelling is a quality signal, although Cutts a few years later mixed messages about whether or not it's important.

38. Syndicated content: is the content of the original of the page? If it is deleted or copied from an indexed page, it will not rank as well ... or it will not be indexed at all.

39. Mobile friendly update: often referred to as " Mobilegeddon ", this update rewarded pages that were correctly optimized for mobile devices.

40. Mobile usability: Websites that are easy for mobile users to use can have a head start in Google's "Mobile-first Index".

41. "Hidden" content on mobile: hidden content on mobile devices may not be indexed (or may not be weighted as heavily) as fully visible content. A Googler has recently stated that hidden content is OK. But also said that in the same video: "...if it's critical content, it should be visible..."

42. Useful additional content: according to a now published Google Rater guideline document useful additional content is an indicator of the quality of a page (and therefore for Google). Examples are currency conversion programs, loan interest calculators and interactive recipes.

43. Content hidden behind tabs: do users have to click on a tab to display part of the content on your page? If so, has Google said that this content "should not be indexed".

44. Number of outgoing couplings: too many dofollow-OBLs the PageRank can "leak" ...which could harm the ranking of that page.

45. Multimedia: Images, videos and other multimedia elements can act as a signal for image quality. A industry research for example, found a link between multimedia and rankings:

46. Number internal links that refer to page: the number of internal links to a page indicates the importance of other pages on the site.

47. Quality of internal links Reference to page : Internal links of authoritative pages on domain have a stronger impactthan pages with no or low PageRank.

48. Broken couplings: too many broken links on a page can be a sign of a neglected or abandoned site. The document of Google Rater Guidelines uses broken links to assess the quality of a homepage.

49. Reading level: there is no doubt that Google estimates the reading level of web pages.
But what they do with that information is under discussion. Some say a basic reading level will help you rank better because it will appeal to the masses. But others associate a basic reading level with content mills like Ezine articles.

50. Affiliate links : Affiliate links themselves will probably not harm your rankings. But if you have too many, Google's algorithm may pay more attention to other quality signals to make sure you don't have " thin affiliate site " are.

51. HTML errors / W3C validation A lot of HTML errors or sloppy coding can be a sign of a poor quality site. Although controversial, many SEO think that a well-encoded page is used as a sign of quality.

52. Domain Authority if all things are equal, a page on an authoritative domain will score higher than a page on a domain with less authority.

53. Page's PageRank: not perfectly correlated. But pages with a lot of authority tend to outperform pages devoid of much link authority .

54. URL length: to Long URLs can negatively affect the visibility of a search engine in a page. Various industry studies have shown that short URLs in Google's search results often have a negative impact on the visibility of a page. diverge .

55. URL path A page closer to the home page can get a slight boost of authority compared to pages buried deep in the architecture of a site.

56. Human editors: although Google has never confirmed this, it has patent pending for a system that allows human editors to influence the SERPs.

57. Page category: the category on which the page appears is a relevance sign. A page that is part of a closely related category can get a relevance boost compared to a page stored under an unrelated category.

58. WordPress Tags: tags are WordPress-specific relevance signal.According to Yoast.com :
"The only way to improve your SEO is to link one content to another, and more specifically a group of messages to each other."

59. Keyword in URL another relevance signal. A Google representative recently called this a " a very small ranking factor “. But a ranking factor anyway.

60. URL- series : The categories in the URL-series are read by Google and can give a thematic signal to what a page is about:

61. References and sources: References to references and sources, such as research documents, can be a sign of quality. According to Google's quality guidelines, reviewers should be wary of sources when viewing certain pages: 'This is a subject where expertise and/or authoritative sources are important ...'. However, Google has denied that they use external links as a tracking signal.

62. Bullets and numbered lists: Enumerations and numbered lists help divide your content for readers, making them more user-friendly. Google probably agrees and may prefer content with bullets and numbers.

63. Priority of page in sitemap: the priority given to a page via the sitemap.xml file may affect the ranking.

64. Too many outgoing links: Straight from the above quality assessment document: "Some pages have far too many links, obscure the page and distract from the main content".

65. Number of other keywords Pagearangen Voor: If the page is used for several other keywords, Google can give Google an internal sign of quality.

66. Page time: Although Google prefers new content, an older page that is updated regularly may outperform a newer page.

67. User-friendly layout: Cite the Google Quality Guidelines Document again:
"The page layout on pages of the highest quality makes the main content immediately visible".

68. Parked domains one Google update reduced search visibility of parked domains in December 2011.

69. Useful content: as noted by Backlinko reader Jared Carrizales , can Google distinguish between "quality" and "useful" content .

Site level factors

70. Content offers value and unique insights: Google heeft verklaard dat ze sites die geen nieuwe of nuttige dingen brengen, en met name niet-geaffilieerde sites, graag benadelen.

71. Contact page: in the Google quality document mentioned above states that they prefer sites with a 'suitable number of contact details'. Alleged bonus if your contact details match your whois info.

72. Domain Trust / TrustRank: Many SEOs geloven dat “TrustRank” een enorm belangrijke ranking factor is. En een recentelijk gearchiveerd Google-patent met de titel ‘Resultaatbeoordeling op basis van vertrouwen’ lijkt dit te ondersteunen.

73. Site architecture: a well composed site architecture (e.g. a silo list) Google helps thematically organize your content . It can also help Googlebot open and index all pages of your site.

74. Site updates: Many SEOs believe that website updates - and especially when new content is added to the site - have a freshness factor throughout the site. Although Google has recently denied that they use "publication frequency" in their algorithm.

75. Presence of sitemap: a sitemap helps search engines index your pages more easily and thoroughly, improving visibility.

76. Uptime of the site A lot of downtime of site maintenance or server problems can be detrimental to your ranking (and even result in indexation if not corrected).

77. Server location : serverlocatie beïnvloedt waar uw site zich in verschillende geografische regio’s bevindt. Vooral belangrijk voor geospecifieke zoekopdrachten.

78. SSL certificate Google has confirmed that HTTPS is used as a ranking signal.

79. Terms of Service and Privacy Pages These two pages help tell Google that a site is a trustworthy member of the Internet.

80. Dual Meta Information On-Site double meta-information on your site can reduce the visibility of all your pages. In fact, it warns the Search Console you if you have too many of them.

81. Breadcrumb navigation: This is a user-friendly site architecture that helps users (and search engines) know where they are on a site:
Google states that Google Search uses breadcrumbs in the main text of a webpage to categorize the information of the page in the search results.

82. Optimized for mobile: by more than the half of all searches on mobile devices, Google wants to see that your site is optimized for mobile users . As a matter of fact sanctioned Google now websites that are not mobile friendly

83. YouTube: there's no doubt YouTube videos get preferential treatment in the SERPs (probably because Google owns it).
In fact, Search Engine Land has determined that the traffic from YouTube.com has increased significantly after Google Panda .

84. Usability of the site: a site that is difficult to use or navigate can indirectly damage rankings by reducing on-site time, page views and bounce rates (in other words Rank Rank Factors ).

85. Use of Google Analytics and Google Search Console:Some think that having these two programs on your site can improve the indexing of your pages. They can also directly affect rankings by giving Google more data to work with (i.e. a more accurate bounce rate, regardless of whether you receive referral traffic from your backlinks, and so on).Having said that, has Google this fable denied .

86. Ratings by users / Reputation of the site: the reputation of a site on sites like Yelp.com probably plays an important role in Google's algorithm. Google even published a rarely frank overview of how they use online reviews after a site got caught ripping off customers in an effort to get press and links.

Backlink Factors

87. Linking Domain Age: Backlinks of obsolete domains may be more powerful than new domains.

88. # Linking Root Domains: the number of referring domains is one of the most important ranking factors in Google's algorithm, as you can see from this industry study of 1 million Google search results.

89. Number links of individual IP addresses of the C-class: Links from individual class-c IP addresses suggest that a wider range of sites are linking to you, which can help in ranking .

90. Number link pages the total number of link pages - even from the same domain - affects the ranking .

91. Backlink Anchor text as mentioned in this description of Google's original algorithm:
"First, anchors often provide more accurate descriptions of web pages than the pages themselves."
It is clear that anchor text is less important than before (and, when over-optimized , act as a web spam signal ). But keyword-rich anchor text still sends a strong relevance signal in small doses.

92. Alt tag (for image links) : Alt text acts as anchor text for images.

93. Links of .edu or .gov Domains : Matt Cutts statedthat TLD does not affect the importance of a site. However, this does not prevent SEOs from thinking that there is a special place in the algo for .gov and .edu TLDs.

94. Authority of the link page: the authority (PageRank) of the referring page has been a very important ranking since the early days of Google and is that yet .

95. Authority of the interconnection domain the authority of the referring domain can play an independent role in the value of a clutch.

96. Left of competitors: Links from other pages that are in the same SERP may be more valuable for ranking a page for that specific keyword.

97. Links from "expected" websites: Although speculative, some SEOs believe that Google will not fully trust your website until you get a link from a range of "expected" sites in your industry.

98. Left of bad neighborhoods: to the left of so-called "bad neighborhoods" can be harmful to your site .

99. Guest posts: although links from guest posts still have value, they are probably not as powerful as real editorial links (plus, " major " guestposting can get your site in trouble).

100. Links of advertisements: According to Google, links to advertisements may not be tracked. However, it is likely that Google will be able to identify and filter advertising links.

101. Homepage Authority: Links to the home page of a referring page can be of particular importance when evaluating the weight of a site - and therefore of a link.

102. Nofollow Left: This is one of the most controversial topics in SEO. The official word from Google on this matter:
"Generally, we don't follow them."
Which suggests that she's do... at least in certain cases. Having a certain number of nofollow left can also be a natural versus unnatural link profile indicate.

103. Diversity of link types: An unnaturally large percentage of your links come from a single source (e.g. forum profiles, blog comments) may be a sign of web spam. On the other hand, links from different sources are a sign of a natural link profile.

104. "Sponsored links" or other words around link:Words like "sponsors", "link partners" and "sponsored links" can reduce the value of a link.

105. Contextual links: Links embedded in the content of a page are considered more powerful than links on a blank page or elsewhere on the page.

106. Excessive 301 bypasses to page: Backlinks from 301 bypasses dilute any PageRank, according to a webmaster help video .

107. Anchor text internal link anchor text internal coupling is another relevant signal. Although internal links probably have much less weight than anchor text coming from external sites.

108. Name assignment link The link title (the text that appears when you move the mouse pointer over a link) can also be used as a weak relevance signal.

109. Referral domain country TLD: Obtaining top-level country-specific extensions (.de, .cn, .co.uk) can help you better classify in that country.

110. Link location in content: Links at the beginning of a content can weigh sth. then left at the end of the content.

111. Link location on page: where a link is displayed on a page is important. In general, a link that is embedded in the content of a page is stronger than a link in the footer or sidebar area.

112. Linking Domain Relevancy: A link from a site in a similar niche is significantly stronger than a link from a completely independent site.

113. Relevance at page level: a link of a relevant pagealso passes on more value.

114. Keyword in title: Google gives extra love to links of pages that contain the keyword of your page in the title ("Experts linked to experts").

115. Positive left speed: a site with a positive link speed usually gets an SERP boost because it shows that your site is becoming more and more popular.

116. Negative left speed: On the other hand, a negative connection speed can significantly reduce the ranking, as this is a sign of declining popularity.

117. To the left of Hub pages: the Hilltop algorithm Suggests that getting links from pages that are considered top material (or hubs) for a certain topic is given special treatment.

118. Link from Authority sites: A link from a site that is considered an 'authority site' probably transmits more juice than a link from a small, relatively unknown site.

119. Linked as Wikipedia Source: Although the links are nofollow, many think that getting a link from Wikipedia gives you a little extra confidence and authority in the eyes of search engines.

120. Co-incidents: the words that usually appear around your backlinks tell Google what that page is about .

121. Backlink age: according to a Google patent older links have more ranking power than newly minted backlinks.

122. Left of Real Sites versus 'Splogs': due to the increase in blog networks, close Google probably puts more weight on links coming from 'real sites' than on fake blogs. They probably use brand and user interaction signals to distinguish between the two.

123. Natural Link profile: A site with a "natural" link profile will score high and be more durable for updates than one that has clearly used black hat strategies to build links.

124. Mutual links: the page Google's Link Schemesgives an overview of "Excessive linking of links" as a linking scheme to avoid.

125 User Generated Content Links: Google can UGC identify versus content published by the actual site owner. For example, they know that a link from the official WordPress.com blog whole is different from a link from besttoasterreviews.wordpress.com.

126. Couplings from 301: Couplings of 301 bypasses can lose a little juice compared to a direct link.Matt Cutts, however, says that a 301s are comparable to direct links

127. Schema.org Usage: Pages that support microformats may be arranged above pages without them. This can be a direct stimulus or the fact that microformatted pages have a higher SERP CTR:

128. TrustRank of Linking Site: The reliability of the site linking to you determines how much "TrustRank" is passed on to you.

129. Number of outgoing links on page: PageRank is finite. A link on a page with hundreds of external links gives less PageRank than a page with a handful of outgoing links.

130. Forum couplings: due to corporate spamming, Google can link from forums devalue significantly .

131. Number words for linking content: a link from a word with a value of 1000 words is more valuable than a link within a 25 word fragment.

132. Quality of linking content: Links from poorly written or sponsored content do not give as much value as links from well written, content.

133. Sitewide links : Matt Cutts has confirmed that sitewide links are "compressed" to count as a single link.

User interaction factors

134. RankBrain: RankBrain is Google's AI algorithm. Many believe that the main goal is to measure how users interact with the search results (and rank the results accordingly).

135. Organic click frequency for a keyword : according to Google pages that are clicked more in the CTR can get an SERP boost for that specific keyword.

136. Organic CTR for all keywords The organic CTR of a site for all keywords to which it applies can be a human based, user interaction signal (in other words, a ' quality score' for the organic results ).

137. Bounce rate: Not everyone in SEO agrees on the bounce rate, but it can be a way for Google to use their users as quality testers (pages with a high bounce rate are probably not a great result for that keyword) . Also found a recent study by SEMRush a correlation between bounce rate and Google rankings.

138. Direct traffic: er it is confirmed that Google data from Google Chrome used to determine how many people visit the site (and how often). Sites with a lot of direct traffic are likely to be sites of higher quality than sites that receive little direct traffic. The SEMRush study I just mentioned even found a significant correlation between direct traffic and Google rankings.

139. Repeat traffic Sites with returning visitors can get a Google ranking boost.

140. Pogosticking: "Pogosticking" is a special type of bounce. In this case the user clicks on other search results in an attempt to find the answer to his question. Results where people can 'Pogostick' from downgrade significantly .

141. Blocked sites Google has terminated this function in Chrome. However, Panda used this function as a quality signal.Google can still use a variant of this.

142. Chrome bookmarks: we know that Google collects Chrome browser usage data . Bookmarked pages in Chrome may get a boost.

143. Number of comments: pages with many comments can be a signal of user interaction and quality. As a matter of fact a Googler said that comments "a lot" can help in ranking.

144. Dwell Time: Google pays much attention to 'dwell time': how long people spend on your page when they come out of a Google search. This is also called 'long clicks versus short clicks'. In short: Google measures how long Google searchers spend on your page. The longer it takes, the better.

Special rules for Google algorithms

145. Query deserves freshness: Google gives newer pages a boost for certain searches .

146. Query deserves diversity: Google can add diversity to an SERP for ambiguous keywords like "Ted", "WWF" or "ruby".

147. Browsing by the user You probably noticed this yourself: websites you visit often get an SERP-boost for your searches.

148. User search history: Search chain Influences search results for later searches . For example, if you search for 'reviews' and then search for 'toasters', Google will rank the review sites for toasters in the SERPs sooner.

149. Highlighted fragments: according to a SEMRUSH study Google selects highlighted fragments based on a combination of content length, formatting, page ownership and HTTP usage.

150. Geographical targeting: Google prefers sites with an IP address from a local server and a country-specific domain name.

151. Safe search: search results with curse words or adult content will not be displayed for people with SafeSearchEngaged.

152. Google+ circles: Although Google+ is essentially dead, Google displays higher results for authors and sites you've added to your Google Plus circles.

153. "YMYL" Keywords: Google has higher quality standardsfor "Your money or your life" words.

154. DMCA complaints: Google "downranks" pages with legitimate DMCA complaints .

155. Domain Diversity the so-called " Bigfoot Update "supposedly added more domains to each SERP page.

156. Transaction searches Google sometimes displays other results for shop-related keywords, such as flight searches.

157. Local searches: for local searches, Google often places local results above 'normal' organic SERPs.

158. Top Stories section: Certain keywords activate a Top Stories box:

159. Big Brands preference: after the Vince update Google started boosting major brands for certain keywords.

160. Store results: Google sometimes displays results of Google Shopping in organic SERPs:

161. Image results: Google images sometimes appear in normal, organic search results.

162. Easter Egg Results: Google has a dozen Easter Egg results . For example, if you search for 'Atari Breakout' in the Google image search, the search results become a playable game (!). Scream out for Victor Pan for this one.

163. Results of individual sites for brands: Bring domain- or brand-oriented keywords different results on the same site .

164. Payday Loans Update: this is a special algorithm designed to " highly spammy searches "...to clean up.

165. Brand name Anchor text: brand anchor text is a simple - but strong - brand signal.

166. Marked searches: When people search for your brand on Google, it shows Google that your site is a real brand.

167. Brand and keyword searches: Do people search for a specific keyword together with your brand (for example: "Backlinko Google ranking factors" or "Backlinko SEO")? If this is the case, Google can give you a ranking boost when people search for the unbranded version of that keyword in Google.

168. Site has a Facebook page and loves: Brands usually have Facebook pages with lots of likes.

169. Site has Twitter profile with followers: Twitter profiles with many followers indicate a popular brand.

170. Official Linkedin Company Page: the Most real companies have LinkedIn pages of companies.

171. Known authorship: in February 2013, Google's CEO Eric Schmidt claimed to be famous:
"In the search results, information linked to verified online profiles will be ranked higher than content without such verification, which will result in most users naturally clicking (verified) the top results".

172. Legitimacy of Social Media Accounts: a social media account with 10,000 followers and 2 posts is likely to become lots of interpreted differently than another 10,000-strong account with a lot of interaction. In fact, Google filed a patent for determining whether or not social media accounts were real or fake.

173. Brand entries on Top Stories: Very big brands are always listed on Top Stories sites. Some brands even have a feed with news from their own website, on the first page:

174. Non-linked brand names: Brands are mentioned without being linked. Google probably looks at brand entries without hyperlink as a brand signal.

175. Brick and Mortar Location: real companies have offices. It is possible that Google searches for location data to determine whether a site is a big brand or not.

Web spam factors on the site

176. Panda Penalty: sites with low quality content (in particular content farms) are less visible in the query after they have been searched by a Panda-penalty have been hit.

177. Links to bad neighborhoods: Linking to "bad neighborhoods" - such as spammy pharmacies or payday loan sites - can damage the visibility of your search.

178. Diversions: Sneaky diversions are a big no-no. If it is caught, it can get a site that is not only punished, but indexed.

179. Pop-ups or "Distracting Ads": the official Google Rater Guidelines Document says pop-ups and distracting ads are a sign of a low quality site.

180. Interstitial pop-ups: Google may penalize sites that display full interstitial popups for mobile users.

181. Site-over optimization: Yeah, Google punishes people for over-optimize their site. This includes: keyword padding, head tag padding, excessive keyword decoration.

182. Gibberish content: a Google patent outlines how Google can identify "gibberish" content, which is useful for filtering spun or automatically generated content from their index.

183. Doorway pages: Google wants the page you show to Google to be the page the user eventually sees. If your page redirects people to another page, it is a 'Doorway page'. Of course Google does not like sites that use Doorway pages.

184. Ads above the fold: the " Page Layout Algorithm "punishes sites with a lot of advertisements (and not much content) above the fold.
