Quality Link Building is one of the most important factors in building your search engine reputation. It is not enough just to have a lot of backlinks. It is the quality of backlinks more than the quantity that will help you rank better in search engines.
Quality links do not just appear randomly—you have to work for them. Acquiring these links may be time-consuming, but they will benefit your site greatly for as long as they remain. While you may not have complete control over who links to you naturally, quality links are what you should aim for in your artificial link building efforts.
There are four main categories that search engines look at when evaluating a link’s quality: site attributes, page attributes, relevance, and anchor text. Each one will be looked at in turn.
Rank – They come from sites with a high number of quality backlinks. The more highly ranked the site is the more it will impact your search ranking.
Popularity – The site the link resides on has a lot of traffic. The more traffic the site has the more visitors it can refer to your site.
The next quality link building factors are those relating to the page linking in to your site.
Link quantity – The value of a link on a page increases the fewer links the page contains. Additionally, an external link appearing site-wide on every page may even be completely devalued.
Link age – Long held links weigh more heavily than new links. The value of a link therefore increases over time.
Permanence – You should aim for permanent links. The ranking boost a link provides is lost when it is no longer there.
Concentrate your quality link building efforts around sites within niches similar to your own. These are not only much more valuable in terms of search ranking, but visitors to those sites will also be more interested in your site, and therefore be more likely to click through to it. There are three types of relevance: niche, page, and context relevance.
Niche relevance – A link from a site related to your site’s niche is better than one that is not, in terms of both the ranking value it provides and the traffic it generates.
Page relevance – The subject of the linking page and the linked to page should be related to provide the most ranking and traffic value.
Context relevance – A link from inside an on-topic paragraph carries greater weight than a link from outside the content, for example, in the sidebar or footer.
Anchor text is one of the most powerful link ranking components. In terms of SEO, the best links are simple HTML text links. The anchor text of the link should include the descriptive keywords that you have optimized the page to rank for. Search engines use this text to help determine the subject matter of the linked to document. To make your links seem more natural, you should mix up the anchor text a bit with different keyword phrases.
