Keyword cooccurence

[mickey11]

Is there any truth to keyword cooccurence being a ranking factor in google or any other search engines. Meaning that they not only look at the words you are targeting but the other words on the page to see if those words have a close relationship to the main theme ( the words being supposedly targeted)

I heard that keyword coocurrence does not scale well over the billions of pages that are on the internet however, some waterdowned approached of keyword cooccurence is possible.

what do you guys think?

I think they definitely do that for spamming reasons, otherwise you could make a million pages with latin text and only put your keyword repeated in the content and get it ranked.

A real article speaking about a topic would generally have similar related words also included in the article.
