Nowadays, the world’s search giant is known to operate with a comprehensive ranking algorithm, which relies on about two hundred different factors. Among the others, Google search engine evaluates backlinks of every website profile using about a dozen different qualities of compelling SEO. Before showing you what exactly is taken into account by Google to “understand” the real value of every backlink on the Web, let me start with some basic teminology.
What Makes a Backlink?
First and foremost, what is a backlink by definition? Like Google itself, every major search engine identifies backlinks as inbound or incoming links from any third-party online resource, back to your own website. And let’s face it - earlier this year there was the first exact message ever voiced by Google’s officials about inbound link profile being among the primary three ranking factors. That’s why Google search engine gives backlinks so much importance for now. To put it simply, they are the “votes” of confidence, which validate every website’s trustworthiness among the users and reconfirm the quality of every page content on the whole.
The thing is that “the ideal” authority website at scale means every page is trusted by the live users, the industry experts (or market niche influencers), as well as the other authoritative websites or blogs, and the major search engines after all. Note, however, that any online source with a high authority doesn’t necessarily mean that it’s one of the most visited publishers of nearly global sale. After all, if one is running a niche blog or website with a unique, valuable, and relevant content - such source might as well be highly regarded, perhaps even better than most. That way, every search engine verifies backlinks to decide if the website or blog is worth showing among the top results on the SERPs.
Google Search Engine Verifies Backlinks by:
individual referral domain count linking to every page of your website or blog;
link profile diversity (i.e., set of different backlinks, with unequal PageRank, coming from as many various places on the Web as possible);
pagerank (PR), domain authority (DA), and page authority (PA) of each online source linking to your web pages (i.e., it’s far better to have a few backlinks with high authority and trust, rather than a huge pack of low-quality ones);
backlinks from the aged domains are usually seen more valuable than the ones from the newborn resources having gone live more recently;
relevant websites or blogs will deliver normal backlinks with considerably greater value if compared to nearly null and void links coming from irrelevnt sources;
applying for Black-Hat SEO (for example link farms, spam links, doorway pages, link wheels, hidden anchors, etc.) got an extreme potential to bring severe negative impact on the current website rankings;
inbound context links (i.e., backlinks found in the main body text of web page content) are much more powerful, rather than any other site-wide (otherwise, footer) links seen in separate widgets, plugins, or other on-page sections.
