PageRank (PR) page does not refer to Web pages, but to Google founder Larry Page, the patent he applied for in 2001, named after his own name, Google's PageRank measure the value of a site based on the number and quality of external links and internal links.
TrustRank (trust index) is a 2006 Yahoo application of a patent, trusted rank is used to detect spam sites, but now the search engine ranking algorithm, often affect the overall ranking of most sites, The interesting thing is that what you usually say about TrustRank is Google algorithm.
Google PageRank Flaw
We know that the PR value of the site is often shown in the past 2-3 months a point in the value of a time, and the most important reason is the size of the PR value is to rely on a large number of inbound links to get a good value, this technique can cheat, can buy and sell links, can achieve results. In fact, the PageRank factor, as the most important factor, represents the PageRank judgment.
Google is also aware of the problem, and in the last PR update post blog said: "Over the years Google Webmaster Center team has been warning the vast number of webmaster, should not be so dependent on PageRank, as a representative of the success of the site index." "And Lou through practice also proved that the level of PR value and the ranking of the Web page is not very related."
About TrustRank
Google TrustRank's impact has become more and more obvious, trustrank using a half artificial way, through Google or some other search agency experts, first to determine the number of site TR value, and then through the machine's connection structure analysis to determine the other site's TR value.

2: Content is original, invest time and energy continue to increase the original content, the site has a good user experience at the same time, look more professional, in this area to establish authority.
3: The age of Domain name is an important factor, 5-6 years of domain name has a higher ranking, so that the search engine can easily detect spam activities.
4: Reverse link correlation, if you purchase 50 pr3-4 backlinks, Google is very easy to detect, if not related sites, these links may reduce your TR ranking.
5: Content duplication, resulting in a drop in traffic is an important reason is that the content of hundreds of sites repeat, often unlucky is those small sites.
6: The quality of the server, including independent IP, the site can be sustained and stable access, the site is cited by a number of international IP segments. '
