Google penalty site in the form of a lot, according to the site violates the Google Webmaster guidelines, the severity of the punishment also has the size. The web site that is being punished is not necessarily in serp, and in some cases it simply does not appear.

Google Supplemental Index (supplemental Index)

Google Sandbox effect

Many SEO experts speculate that new sites must undergo a trial period to get a good ranking at Google. In fact, many new sites seem to have passed this stage, and many people have found that this period is about 6 months in length. Matt Cutts in an interview with Barry Schwartz that "there may be a sandbox-like thing in the algorithm, but not every industry."

We believe that Google may not have a "sandbox" explicitly, but the effect is real. For this reason, it should be considered "effect" rather than "punishment". It may be a composite effect of several algorithms, not a sandbox algorithm. Many sites do not appear to be bound by this rule, especially those that get links from authoritative sites. For example, some links from authoritative websites and other famous web sites may allow a Web site to be freed from the sandbox effect.

Some people assume that Yahoo has similar algorithmic factors, but not so serious and clear. MSN Search does not seem to have such a similar implementation.

Expired Domain name penalty

Start a new web site using a previously expired domain name that was previously used to escape the sandbox effect. It used to work because Google didn't realize the site was new. Google has recently made up for this loophole, and it now seems to be an occasional opportunity.

An expired domain name may now be temporarily penalized. This is important because additional latency is added before the site gets a good ranking. In some cases, Google will not even be able to retrieve the pages at this time, allowing the site to be stolen by the content.

Google may also be able to score any links that were obtained before the domain was re-register. Other search engines do not seem to be punishing the previous expired domain names.

Repeat content penalty

Search engines try to avoid retrieving multiple copies of the same content, that is, duplicate content. Many search engine optimization experts believe that the search engine not only will not retrieve this page, but also the site containing duplicate content punishment.

There is still controversy over this issue, but in any case, the duplication in the site does not increase the rankings in any of the mainstream search engines. Therefore, you should avoid duplication of content, about how to avoid duplication of content, there are related articles introduced separately.

Google Supplemental Index

This is not a strict punishment, but it may be the result of punishment. Google places the search data it collects in two indexes: the primary index and the Supplemental Index (supplemlental index). The supplemental index stores pages that Google considers less important for a variety of reasons. The results from the Supplemental index usually appear at the end of the Google query (unless the query is very special), and these results are labeled as supplementary results.

Despite the current external view, Google has shown no sign of a supplemental index, but it may still be one of the procedures for Google to judge the value of a Web page.

There may be times when you just accidentally violate the rules of the search engine. So how do you find out if your site is being punished by search engines?

1. Search your domain name, such as search: www.smzpw.com.cn, your site is not ranked first. (Note, this method only has been included in the search engine site effective, just set up the site is often the case, but because the establishment of time is too short, but also bought to be indexed by the search engine)

2. Search "site: your domain name", such as "site:www.smzpw.com.cn" returned 0 results;

3. The number of visits from search engines has dropped dramatically in a short time.

4. The number of Web pages included in the search index database has dropped rapidly.

5. Search engines are getting fewer links per month, or even 0.

6. The homepage can only be searched by the direct input URL, any search request to the keyword on the webpage no longer works.

If these conditions arise, your site may be punished. The worst case scenario is being blocked by multiple search engines, if you have a few search engines to find your site, but the other can not find, your site may be restricted, if your violation is not serious to ban the site, you will still suffer some punishment, The search engine will remove a lot of your pages from the index library or lower your search rankings.

You need to clean up the cheating on your site in time, and then ask the search engine to recover, and the search engine will usually agree.
