Today, Mr cubo list some of the most common search engine optimization cheating practices,Sometimes, these cheating practices intended to be used webmasters, attempts to manipulate and deceive the search engine. However, some time, many webmasters may inadvertently use of these practices. He had the other goal is to achieve the effect, but it inadvertently violated the search engine required by the norms.

Whether site owners to employ other designers, or design by theirself, need to pay attention to their own sites can not use these SEO cheating practices.

doorway pages

Is usually the software automatically generate a large number of web pages containing keywords, and then from these pages to do so automatically to the home page. The purposes are to these goals in different keywords for the doorway pages in search engines have a good ranking. When a user clicks on the search results, will automatically go home. Sometimes the bridge is placed on a page of links to the home, rather than automatic shift.

In most cases, these doorway pages are generated by the software. You can imagine, generated text is haphazard and there is no logic.

keyword stuffing

The page in a large number spelled words to enhance Keywords density, improve the website for keywords related degrees. Key words can be spelled in many places, such as the user can see the text itself, may also be in the title tag Title Tag, Key words labels that tab.

It should be said that as the search engine algorithm improvements, keyword density is not an important factor. Such cheating practices can only bring trouble to your site.

hidden text

Hidden text in the HTML page document containing keywords placed in the text, but these characters can not be seen by users, search engines can only be seen. Can have several forms, for instance, the famous ultra-small text, with the same background color of the text, comments on the label of the text on the table inside the label text input, through the stylesheet not visible on the text of the above And so on.

The aim is also to enhance the relevance of the page.

Sometimes, some people still put these places has nothing to do with the site’s content, but very popular words in the hope that the website can be under these popular keywords good position and flow.

hidden link

Hidden links and hidden text similar, but the difference is the Key words on the link inside, and this link is also the user can not see.

cloaked page

Some of the page or the procedures used to detect the script to access the search engine or ordinary users. If a search engine, the page on the return of optimized version of the page. If the visit is the ordinary people, return is another version.

Such cheating, users do not usually found. Because once you look at this web browser, whether on the page or in the HTML document, you have received is a search engine and see the different versions. Detection method is to look at this page snapshot.

link buying

While other sites to buy ad is very normal thing, but sometimes if purchased by advertising links simply to increase page-level PR or to manipulate search engine rankings, it will also be used as means of cheating.

How to distinguish between the normal means of advertising and cheating among a very fuzzy boundaries. But to do so themselves mind is clear. If your site is considered by buying links to cheating, and no way to search engines to argue. Because the search engine’s decision is final.

like PR Hijack, on some of the more difficult to prevent the Black Hat trap tactics, do not want to have a positive discussion, because there are a lot of time on the innocent chief cause great harm.Such things are double-edged sword, If the people have ulterior motives read,they will have a another tool of profiting at others’ expense. On the other hand, has suffered the station master saw, perhaps for their prevention and recovery have a positive significance.

Proxy Hijack means that search engine throug a proxy to visit the page and the page was the real punishment or deleted.

In the use of proxy servers on other sites, the browser display is usually similar to the URL:

http://www.proxysite.com/proxy/www.yoursite.com

Proxysite.com which is a proxy server domain names, yoursite.com is really to visit the site.

Use browser to open this URL of course, no problem, but if search engines to crawl this URL, the original site will be a full copy content pages. Although the copy content pages in most cases not only be ignored or, in some cases, the search engine made an error of judgement, as will the original version and the copy is being punished even be deleted.

Under normal circumstances, through a proxy to visit the URL should not be included. But if it was malicious link to the agent URL, access and search engines will crawl.

How to prevent or restore the ranking of Proxy Hijack?

The simplest, to see if their page was hijacked agent, check that the proxy server’s IP address, on their own servers to shield out that IP address, ban crawl.

However, some time, the proxy server’s IP address there will be changes, but also so many proxy servers, but is likely to shield. The method is more complex server-side through the identification process is whether or not to visit the search engine spiders, it is the real search engine spiders.

In some cases, the search engine spiders through a proxy URL to visit the browser type (User Agent), or search engine spiders. However, some proxy servers may be set up to hide the original IP address, hidden User Agent, which is to determine whether the search engine spiders cause great difficulties.

Then site verification procedures need to take the initiative here really is whether the search engine spiders. If the test procedure is indeed the real spiders, to return to normal pages. If the test is not the spider is a normal user, or fake spider, then returned to the pages are joined noindex, nofollow tags. So that these original page through a proxy access, can not be crawled by the search engine.

As we all know, Google PR is a important thing which webmasters in pursuit of, though not necessarily with the rankings, but the little light green on the toolbar,let peoples exciting.

Today,Mr.Cubo is to talk about the PR hijacking, which is used deception to obtain the toolbar relatively high PR value. Method is to use Jump pages.

In general search engine to deal with the 301 and 302, are the real target should be included as a URL’s URL. Of course there are exceptions, but in most cases this is dealt with.

So if you do A domain name from the 301 or 302 Jump to domain B, B domain PR value is relatively high, in the domain A PR update, the domain B will also show the value of PR. Some people take advantage of this, their PR value of domain names deliberately raising.

At first Jump to 301 or 302 high PR domain B, such as after the PR update, to cancel immediately, put their own content, and then start selling links. This bogus value of PR at least until the next PR update, generally have two or three months time.

Other webmaster came to this site, see a high PR value, but do not know the value of PR is to get abnormality way,the PR value don’t of this site, but another site.

A other way is to use the programme avoid Google’s spiders, to return to 301 or 302, for ordinary visitors and other spiders are content to return to normal. So that we see is a common site, only to see Google.

For example, below this PHP code to achieve this effect:

if (strstr($_SERVER['HTTP_USER_AGENT'], “Googlebot”)) {
header(”HTTP/1.1 301 Moved Permanently”);
header(”Location: http://www.apple.com/”);
exit;
}
else {
header(’Content-Type: text/html; charset=ISO-8859-1′);
};
?>
Here start ordinary HTML code

I do not know programming, just above probably mean, not necessarily accurate.

Both are means of PR value, not their own domain name is the real value of PR. The purpose get the PR value is very obvious,for link sales or RP sale. If the sale is the link to the aspirations of the ad click traffic, the situation may be, if the aspirations of the main or the only demand is high PR value, which undoubtedly is deceiving. This site links to the PR value of no contribution.

So how to identify the PR value of deception?

The most accurate of course, is to see Google’s snapshot, if you see that the page is a kind, Google is the snapshot to see another site, the general site title and logo will show, and I am afraid this is very suspicious of.

Another noteworthy is that the links to find and buy time, if the other side of the show is a high PR value, must be very careful. Links should be to establish the relevance of the content of the main considerations for, PR ranking of the actual level of impact not many people thought so important.
