In the past, back link success or value was measured by Google PageRank. This tool is a most commonly seen in the Google toolbar as the optional PageRank tool.
Although not as important as it used to be, the concept of having links back to your site is still valuable today.
In basic link terminology, a back link is any link from one web site to another website. Back links are also known as incoming links, inbound links, inlinks, and inward links. The links can go from a home page on one site to an internal page on another site or visa versa.
The value of the link is based on many things, most importantly the relevance and importance of the site that the link is coming from. A link from a contractor website to a private investigator website is not going to do much for the private investigator. A link from one private investigator to another private investigator is much more beneficial.
We use a few different processes and tools to improve backinks including three way linking relationships with other relevant sites and web linking companies with numerous sites to link from. There are also many directories from which to gain good links
