It is believed that Google used an algorithm called “TrustRank”, by which search engines determine the true value of a site. Determine to what extent it would be useful for consumers determine how many users would receive dividends from the visit to the site, and many other factors. Trust Rank is different from PageRank. Sometimes TrustRank is compared with the domain’s PageRank, and although there’s some potential reasons for it is good to know that the two algorithm has more differences than similarities. TrustRank is designed to clear SPAM-and the index for this purpose used the idea that the best sites rarely put links to bad sites.
Ranking the importance of various factors over the years and the growth of TrustRank
In 2009, Google received a patent for the Trust Rank. The patent is considered possible links of Trust Rank (confidence level) of users rating the web pages using annotations (ratings and reviews).

A search engine system provides search results that are ranked according to a measure of the trust associated with entities that have provided labels for the documents in the search results. A search engine receives a query and selects documents relevant to the query.
The search engine also determines labels associated with selected documents, and the trust ranks of the entities that provided the labels. The trust ranks are used to determine trust factors for the respective documents. The trust factors are used to adjust information retrieval scores of the documents. The search results are then ranked based on the adjusted information retrieval scores.
The main idea of ​​the Trust Rank patents is that there are many experts on various issues in different sites. These experts have their own pages and participate in discussions on blogs, news sites, forums and social networks. Namely the annotations and labels left by these experts could be used by search engines to redistribute rating in the search results.
The concept of TrustRank-and
One of the important elements to define a CE as an authoritative site is TrustRank (except by Google, such a method of determining the credibility of a resource to be used by Yahoo).

In optimization there are ways to get TrustRank, through certain techniques by which to demonstrate the search engine importance and value of your site.
TrustRank has several aspects. One way to get a good TrustRank is to work on your site consistently and persistently, adding only quality links, update content and not using prohibited techniques (or not if you are caught using :)). Website high TrustRank almost never entered the Sandbox and the opposite site Sandbox is almost certainly bad TrustRank.
Are there other factors to help increase TrustRank? Among the various sources I read a lot, but here the main proposals gathered in the list:
Long domain registration – almost universally recommended if you have serious intentions for the site to make or extend domain registration for 10 years
Availability of SSL Certificate – nice and do not forget to continue it
Use Hacker Safe service and availability of Hacker Safe logo on the site – any links and certificates from various Kid Safe, Family Safe, and Family Friendly sites are more than welcome.
Easily accessible real address (not just mailbox) – the use of microformats, if not help, at least not interfere
Separate page policy on data protection – Privacy Policy
Logos and certificates of large membership sites – BBB, chambers of commerce, payment systems and foundations (foundations or links from sites that thanks to donations have great taste something very decent price :-))
Inbound links from sites with a high TrustRank (to come to the topic πŸ™‚

Factors for improving Google TrustRank
These several actions can show Google, you’re serious about your presence on the Internet, and you want to demonstrate quality information to consumers.
