Keyword proximity refers to how close together your keywords are comparied to how close together they were in the search phrase. For example: If someone searched for this string of words, "peanut butter and jelly" and if your page had the following sentence, "Peanut butter is also good when it is used with jelly." then your page might be found because it contains the words that were searched for but it wouldn't be as likely to be found as it would if the words on your Web page were exactly as used in the search for phrase. Therefore, always try to use your keyword phrases exactly as they are likely to be used in a search phrase.
