One SEO professional was curious about autocomplete suggestions on the Google SERPs.
Danny Sullivan wrote in a blog post, about a year ago on the Google Search blog, regarding how they are generated.
This included a lot of information about these predictions and how they work. Additionally, the SEO pro was curious about the related features on the SERPs (search engine results pages), which are related searches, all the way down at the bottom of the Google search results page.
They couldn’t find any information on this, to be honest.
The only thing that they were able to find came from Google Trends, where they have a similar concept of related searches.
Their definition of related searches here is that these terms are frequently searched with the term you entered in the same session.
Their main question about autocomplete suggestions is: does this also apply to the classic Google Search?
If not, then how are these related searches actually generated and where do they come from?
John replied that they don’t have any documentation on that, specifically.
Usually, things on other search products at Google are not the same across product and search.
While it’s possible that Google Trends may use something similar to Google Search, John warns against assuming that it’s the same kind of algorithm or same setup for that.
He expounded that intuitively, it does sound like it’s kind of similar, and it could make sense for related searches.
He thinks it is similar to a lot of features in search, where they may have some larger aspects documented, but on the smaller aspects, they don’t have exact documentation individually.
