In search engine optimization, a keyword phrase is two or more words determined by comprehensive keyword research and development to accurately reflect the language used by your target audience group to search for what you offer.
The keyword phrase is associated with a specific web page that is being optimized for enhanced search engine performance. The idea is to use it in a variety of legitimate ways that represent best practices in professional search engine optimization. The application of the keyword phrase should help both the search engines and the end-users to gain a clear understanding of the content found on a particular web page.
