keyword phrase in SEO?

[onehalf.transpo]

A keyword phrase is generally two or more words that are used by advertisers in search engine optimization, or by visitors who are using search engines in a desire to find information based on that particular phrase. For example, an advertiser that sells blue carrot shoes might use “blue carrot shoes” as a keyword phrase to draw more visitors interested in the topic. On the other hand, visitors to a search engine looking to buy blue carrot shoes would also use the keyword phrase “blue carrot shoes” in the search engine, which would then match the keyword phrase with websites like that of the advertiser that mention the same keyword phrase.
