What Happened?
On March 13, an automated bot named yoshi-code-bot released thousands of documents on Github. These documents, purportedly from Google’s Content API Warehouse, were shared with Rand Fishkin, co-founder of SparkToro, and Michael King, CEO of iPullRank. Both industry experts have reviewed and analyzed the content, shedding light on the inner workings of Google’s ranking system. This event is being hailed as one of the most significant developments in SEO history, similar to the Yandex search ranking factors leak of 2023.
Why We Care
For SEOs and digital marketers, understanding Google’s ranking algorithm is the holy grail. The insights from these documents provide a roadmap to optimize content more effectively, align with Google’s ranking priorities, and ultimately improve search visibility. The revelations could fundamentally change how we approach SEO, making this leak a pivotal moment in the industry.
What’s Inside the Documents?
Current Documentation
The documents are up-to-date as of March, representing the most current information on Google’s ranking mechanisms. They detail 2,596 modules in the API documentation with 14,014 attributes, providing an extensive view of the elements Google considers.
Ranking Features
The documents list various ranking features but do not specify the weighting of these features. This means we know the factors that influence rankings but not their relative importance.
Twiddlers and Demotions
One of the significant revelations is the concept of “Twiddlers.” These are re-ranking functions that can adjust the information retrieval score of a document or change its ranking. Content can be demoted for several reasons, including:
- Mismatched links to the target site
- User dissatisfaction signals from SERPs
- Poor product reviews
- Inappropriate content (e.g., pornography)
- Location-based issues
- Use of exact match domains
Change History
Google keeps a copy of every version of every page it has ever indexed. However, it only uses the last 20 changes of a URL when analyzing links. This historical approach to indexing means Google can track the evolution of a page’s content and links.
Link Relevance and Diversity
The importance of links remains a critical factor. The documents confirm that link diversity and relevance are key, with PageRank still playing a significant role. This underscores the enduring value of quality backlinks in SEO.
Clicks and User Engagement
Successful clicks are crucial for ranking. Google uses various metrics such as badClicks, goodClicks, lastLongestClicks, and unsquashedClicks to measure user engagement. Longer documents may be truncated, while shorter content is scored based on originality, especially for YMYL (Your Money Your Life) content like health and news articles.
Brand and Entities
Brand recognition and authority are paramount. According to Fishkin, building a notable, popular, and well-recognized brand is essential for improving organic search rankings. Additionally, Google tracks authorship and entity associations with content, indicating that who writes the content matters significantly.
Chrome Data and Whitelists
Google uses data from its Chrome browser for ranking purposes, as indicated by a module called ChromeInTotal. The documents also suggest that certain domains related to elections and COVID-19 are whitelisted, reflecting Google’s use of exception lists to manage specific algorithms’ impacts.
Small Sites and Freshness
The leak reveals a feature called smallPersonalSite, suggesting that Google may boost or demote small personal sites or blogs. Freshness is another critical factor, with Google analyzing dates in bylines, URLs, and on-page content to determine the recency of information.
Other Interesting Findings
- SiteAuthority: Google uses a concept called siteAuthority, affecting how content quality on one part of a site can influence the site’s overall ranking.
- Page Titles: Google evaluates how well a page title matches a query using a feature called titlematchScore.
- Font Size and Anchor Text: Google measures the average weighted font size of terms in documents and anchor text, indicating the importance of on-page content structure.
What Does It All Mean?
Michael King summarizes the findings by emphasizing the need to drive more successful clicks using a broader set of queries and earn more link diversity. This approach aligns with creating high-quality content and providing excellent user experiences, which are fundamental to SEO success.
Key Takeaways for SEOs
- Focus on User Experience: Creating engaging, valuable content that attracts and retains users is more important than ever.
- Diversify Links: Building a diverse and relevant backlink profile remains a cornerstone of effective SEO.
- Monitor Content Changes: Keeping track of content changes and ensuring they align with SEO best practices is crucial.
- Brand Building: Establishing a strong, recognizable brand can significantly enhance search visibility.
- Leverage Data Insights: Utilizing data from tools like Google Analytics and Chrome can provide actionable insights for optimization.
