What is keyword proximity?

Keyword proximity refers to the distance between the keywords, i.e., it tells how close keywords are to each other in a phrase or body of text. It is used to measure the distance between two keywords in the text. It is used by some search engines to measure the relevancy of a given page to the search request. It specifies that the closer the two keywords in a phrase or a search term, the more relevant will be the phrase. For example, see the keywords “Delhi Digital Photographer” in the search term “Delhi Photographer Ram Kumar specialized in digital photography.” The proximity between Delhi and Photographer is excellent, but between the “Photographer” and “digital” proximity is not good as there are four words between them. So, a search term’s keywords should be as close to each other as possible.
