Factors that Influence the Value of a Link
In my last post, I discussed the different types of link building methods that can be utilized. In this post, I want to look further at what factors determine the value of a link. Every link has a different value and you need to understand this if you want to make educated decisions on how you should invest your time and money. Since nobody has complete insight into the inner workings of Google and their algorithm, except people at Google of course, many of the factors that effect the value of a link are not completely agreed upon by experts in the industry. Although there are certain factors that everyone seems to agree on.
The most commonly agreed upon factors are Alexa ranking, Robots.txt excluded page, domain authority (in quality of backlinks), page relevance and the number of links. The most controversial factors are TLD, type of links, domain authority (in PageRank), domain authority (in rankings on irrelevant keywords) and target page location. The most important factors are Robots.txt excluded page, Anchor Text, link is on penalized page, page authority (inbound links), domain authority (in quality of backlinks), amount of outbound links on a page, total amount of links on a page, age of domain, relevant authority (in rankings on relevant keywords) and Javascript link.
