SEO for Google’s Hummingbird is about more than just including a few key phrases in the text on a page.

Its task is to understand what the user wanted to receive by request and find the most relevant answer.

It takes into account geo-targeting, i.e. the geo-referencing of the request, the number of recommendations in social networks for the site, and the user’s interests, which are evaluated by previous clicks. All this should help in finding the right answer to any request.

Fill the site with human content. Exact occurrences of queries play an ever-smaller role in ranking since word forms and the presence of words of the same thematic group are taken into account.
