Keyword Proximity and Keyword weight

Keyword Proximity

Keyword proximity refers to the closeness between two or more keywords. In general, the closer the keywords are, the better.

For example:

How Keyword Density Affects Search Engine Rankings

How Keyword Density Affects Rankings In Search Engine

Using the example above, if someone searched for "search engine rankings," a web page containing the first sentence is more likely to rank higher than the second.

The reason is because the keywords are placed closer together. This is assuming that everything else is equal, of course.

Keyword weight

Keyword weight is the percentage or concentration of keywords on your page in relation to all other words on the page. A "keyword" can be either a single word, or a short phrase.

Keyword weight refers to the number of keywords appearing in the page area divided by the total number of words appearing in that area. Weight also depends on whether the keyword is a single word or a multi-word phrase.
