In this Whiteboard Friday session, Tom Capper discusses four key insights from a recent leak of internal Google documentation on their search algorithm. This leak has provided unprecedented details and confirmed several theories long speculated within the SEO community.
Clickstream
Google has historically denied using Chrome data or click data to inform search rankings. However, the leaked documents confirm that Google does use click data through a system called Navboost and incorporates Chrome traffic data. This revelation underscores the importance of user experience and brand engagement in SEO practices.
SiteAuthority
The documents reveal that Google uses a metric similar to Moz's Domain Authority, referred to as siteAuthority. This metric is primarily used to assess new pages, approximating their value based on the domain-level score. While it confirms the existence of site-level signals, the exact application and weight of this metric remain unclear.
Branded Search
The leak suggests that Google considers the ratio of branded search volume to links as part of its ranking factors, potentially linked to the Panda algorithm. This means that if a site has many links but low branded search volume, it may be flagged as suspicious. This insight aligns with observations that sites with strong brands tend to perform better in organic rankings.
Demotions
The documents detail various algorithmic penalties, including exact match domain demotion and product review demotion. Google appears to target product review sites, possibly due to their association with low-quality content or affiliate links. Another mentioned demotion, nav demotion, could relate to poor navigation experiences on websites.
These insights provide valuable confirmation and new information for the SEO community, highlighting the importance of user experience, brand strength, and content quality in Google's search algorithm.
