A contextual link is one in which the clickable text is made up of a keyword phrase you want to obtain a good ranking in Google or other search engines.

Be careful though many of these links are obtained by money and Google doesn't like the buying and selling of links for extra ranking.

Also be sure these links are relevant to your site otherwise they will count for nothing, their SEO value will be worthless.

Writing good articles is the best way to create strong links to your site especially if it's on a blog or forum that is relevant to your business category.
