RankBrain is a machine learning system that helps Google sort their search results. Your search engine results page (SERP) or the order Google displays results on its search page is depended on several factors. Google uses a trademarked algorithm called PageRank, which assigns each Web page a relevancy score. Which is again depended on factors like :
- How long the Web page has existed
- How frequent the keywords were used within the Web page and their location
- The number of other Web pages that link to the page in question and so on …
But now things have started changing. Now it’s not just about keywords and web links, now Google measures how users are interacting with the search results.
RankBrain simply measures how users interact with the search results and rank them accordingly.
RankBrain mainly focuses on two factors :
- Dwell time
- Percentage of people click on your result.
Dwell Time is nothing but How long someone spends on your page (The more time they stay on your page, the better). It is found that the average Dwell Time for a top 10 Google result is 3 minutes and 10 seconds.
The more time you spend on a website gives Google an idea that the user probably likes the content and is relevant. And then they uprank the result in search page. So that user can find the useful content upfront.
