A word or a short phrase that sums up the contents of a web page. Keywords are one of the main ways search engines determine relevance to a user’s search query and form the backbone of SEO. Note that keywords are not the same as a search query. The way you use keywords has a huge impact when it comes to on-page SEO, off-page SEO and backlinks.

A good keyword strategy should use keyword research to find keywords with a range of keyword intent.
