By installing a Google Toolbar or a series of PageRank measurement and analysis sites in a Web browser, you can measure the PageRank value of a site, and in fact, measuring the PageRank value of your site or competitor's site is meaningless, Once people realized that they could manipulate the Google search algorithm by accessing a large number of links from highly PageRank sites, all this was meaningless.
PageRank lose meaning
The PageRank, which once updated every one or two months, are becoming less frequent, and now they are almost meaningless because the PageRank update displays data that is not current data and is useless. We can verify whether it is true, first select an industry keyword and search on Google, browse the top ten of the search results, write down the PR value of the site, you can find, not as we think, the PR value of the site ranked in the top of the search results, but some PR value is very small or even zero site, Compared to those sites with high PR value, they got a higher ranking in search engines. The reason is that PageRank itself has ceased to function long ago, and Google Now updates PageRank in the toolbar is merely a symbolic gesture, and it is estimated that in the next two or three years they will permanently stop updating PageRank.
TrustRank is important.
TrustRank has been playing an important role in replacing PageRank for some time now. TrustRank can be translated as "Trust Index", as the name suggests, it measures the site's trust on Google, the higher the site's TrustRank value, meaning that the higher the quality of the site. Of course, Google learned the former lesson, no longer its own search engine internal work mechanism to the public, in case someone else try to manipulate, the destruction of fairness.
Here are some factors that can affect the TrustRank value of a Web site and thus affect search engine rankings: 1. Domain name registration time in five years or five years; 2. Web site hosted on a dedicated server; 3. Site loading time is fast; 4. The site content is original; 5. Visitors stay longer than 90 seconds per page; 6. The website is referenced by several international IP segments; 7. The website has authority in its industry. These are the qualities that commercial websites and blogs should have, not those that use spam and fake inbound links to make quick money.
Although the TrustRank algorithm was originally used as a garbage detection method, in the current search engine ranking algorithm, the TrustRank concept is more widely used, often affecting the overall ranking of most sites. So, TrustRank is really important, really worthy of attention. (CNPDA Smart Mobile Forum bbs.icnpda.com reprint)
