Here we look at the world is the search engine giant Google to penalize websites which way? Google has a lot of punishment in the form of websites, according to Google's webmaster guidelines, depending on your degree of violation, the intensity of the punishment is different, being punished website is not necessarily in the SERP, would not appear in some cases, below 'll take you to know Google several punishment.
One, Google Sandbox Effect (sandbox effect)
Second, the expired domain punishment
Third, duplicate content punishment
Four, Google supplemental index (supplemental index)
Next we will learn some of the details of the punishment:
Google Sandbox Effect
Many search engine optimization experts have speculated that the site emerging must go through a test period in order to get a good ranking on Google, in fact, a lot of the new site seems to have passed this stage, and many people find that it takes about the period maintained for 6 months. In an interview with Matt Cutts Barry Schwartz's talked about, "there may be something of a similar algorithm in the sandbox, but not every industry there.
We believe that Google may not explicitly have such a "sandbox", but this effect is true, therefore, it should be considered "effect'' rather than" punishment. "It may be the combined effect of several algorithms , and not a "sandbox algorithm." It seems not many sites that rule constraints, especially those sites to get links from authority sites. example, some links from authoritative sites, and other well-known Web sites, it is possible Let freed from a Web site in the sandbox effect.
Some people assume that Yahoo has a similar algorithm factors, but not so serious and clear, MSN Search does not seem like such a realization.
Expired Domain punishment
Using a previously expired domain name to launch a new Web site, used to be used to evade the trouble is "sandbox effect." Previously able to work because Google has not yet realized that this site is new, recently Google has been to make up for this flaw, it now appears only occasionally happened in the opportunity.
Now an expired domain name may be temporary punishment, which is important, because before to get a good ranking on the site adds additional delays, in some cases, Google will not even go to retrieve these pages during this period, despite This site is stolen content.
Any links Google may also get re-registered the domain name before the drop points. And it seems other search engines will not penalize the front of this expired domain names.
Penalize duplicate content
Search engines try to avoid multiple copies of the same content (ie duplicate content) to search, many search engine optimization experts, search engines will not only not retrieve this page, but it will also contain duplicate content on the site punishment, in there is controversy on this issue, but in any case, the site will not duplicate content to improve the ranking in any of the major search engines, therefore, should avoid excessive duplicate content.
Google supplemental index
This is not a form of punishment in the strict sense, but it may be the result of punishment, Google will search data it collects on two indexes: the main index and the supplemental index (supplemlental Index). Google supplemental index stores various reasons considered less important pages, typically results from the index added in the last Google search results (except the very specific query), and these results are marked as supplemental results.
Although from the outside, Google has not show any mark on the supplemental index, but may still be inside one of Google to determine the value of the program pages on Google's punishment, there are many, such as negative about the ranking 6 minus 30, minus 60 punishment, and so reduce the overall ranking website.
If your site is being punished Google, after reading this article contrast under their own website, to find out the cause of your site being punished, coupled with correct, Google will continue to index your site, and some say the site into the sand Boxes are generally three months, if you do well in these three months, the site will come out from the sandbox, and vice versa will continue to stay in the sandbox inside reflection.
