When it comes to build links targeted to specific keywords, you need to keep in mind the relevance of the overall keyword phrase.  For example, let’s talk about a keyword phrase like ‘Credit Card Offers”

The Google ranking algorithm does use relevancy for its search results.  There are 3 main components – Technical, Content, and Links.  The first two items – Technical and Content – are primarily based on your website.  The third – Links – is the basis for Google PageRank, which is collective the most dominant of the 3 components.

In this example, I might build links for “Credit Cards” and “Credit Card Offers”, but not “Offers”  This is because you can build relevance for ‘Keyword Phrase 1′ and ‘Keyword Phrase 2′, if both are relevant to your website.  However, the content and the linking will be harder to establish relevancy for “Offers” as a stand-alone phrase.

In addition, once you rank for a particular keyword like “Credit Cards”…Google will watch the behavior of its users to see if they like to visit your site after typing this keyword and it if seems like a majority of users are happy with the result, this also confirms relevance.  All of this is done by algorithms, Google states in several public releases and their methodology supports that ‘hand-editing’ doesn’t occur for top rankings.
