Keyword proximity refers to how close together keywords are to one another, or to another element on the website. There is a real art to nailing down keyword proximity within a body of text. The goal really isn’t to have all of your keywords within a close proximity, but it definitely is something to consider. One common piece of advice you will find is that the closer your key phrase is together within a piece of content, the more relevant that page might be Googlebot for that particular keyword or key phrase.
