We have often mentioned the need to build a good network of links that will help us improve our Pagerank and our organic positioning. And we have also clarified that not all links that link us are quality, and that we should aim to achieve incoming links from sites of good PR. The reality is that in terms of incoming links, is sometimes better few but good, that many and of poor quality. It is necessary at this point to clarify what we mean with bad quality links: links from link farms. Definitely, they are not places where we would like to be listed. It is not enough to check the PR of the site where our link is.
It is also important to know how many outbound links have. Google is very smart, and two things immediately catch your attention: the titles as Webs Amigas, and the large amount of outbound links, especially when they are to websites of different nature (perfumeries, sites of bets, download programs, etc.). Google said that it suggests that the sites do not have more than 100 links to other websites per page <>. And also draws attention to a momentous question: more links have one page shall be apportioned that PR between all the outgoing links, so ultimately, only a tiny part of the PR of the site will have the link site. The contextual links are links within relevant texts that are semantically related to the keywords you are looking for position. The most obvious example are the links that are included in articles in a blog. For example, if your blog is about dogs and other domestic animals, a contextual link is one that included for example in the phrase food for dogs, pointing to a site that speaks precisely of that. But if you include a link to a site on vacation in the Caribbean, there is no relationship with the theme of the blog.
Consequently, it is not a quality link. Contextual links generate trust and credibility by the search engines that we indexed, provide relevant information to our readers, and our PR increase. As a result, when we seek incoming links, it would be optimal if them were contextual. Examples of this can be articles that we write for other sites with the same theme, professional directories, or specialized sites. An excellent way to have contextual links pointing to our site may be through participation in specialized forums, or relevant to our subject communities. Achieve a network of contextual links linking us may take more time that simply buy links, or make exchanges with sites that are in bad neighborhoods, as same Google defines it. However, the result will be much better, and will be worth every minute of time invested.
