Most webmasters already know that repetitive content can negatively affect the ranking of sites. But how can you check a particular website for this problem and how can you reduce or avoid it?

From the outset, you can divide the duplication into two main categories:

Duplicate content caused by web site structure

Content theft caused by duplication

About duplicate content caused by web site structure

Some web site structures themselves can cause duplicates, as shown in the following example:

Print Friendly (ptint-friendly) pages

Have roughly similar content on multiple pages and can be accessed through different URL addresses

There are very similar units on the page, such as in an e-business category, a series of different color linings with similar descriptions

The page is part of a tracking application's membership program, and the program is not configured correctly

Multiple pages have duplicate headings or duplicate meta tag values

Use session ID in URL address

Standardization issues

To find the duplicate content caused by the site structure, you can use the site:www.yingyuxuexi.org.cn query string to check the URL address of a Web site that has been indexed by a search engine. All major search engines (Google,yahoo!,microsoft Live Search) support this feature. Typically, a "print friendly" page is indexed and quickly displayed.

Google often places what it considers to be a duplicate content in the Supplemental Index (supplemental index). At the bottom of the search engine results there is a tag for the supplemental material, which is what is placed. Of course, Google has now hidden the logo. If a Web site has many pages that appear in the Supplemental index, it may mean that the pages are duplicates-at least as Google thinks. If possible, study the URL address of these pages and find out if there are any previously mentioned situations. In particular, look at the page that is behind the result. If you do not pay attention to the problem is particularly easy to duplicate content, so in favor of the search engine point of view will be useful.

About content theft caused by duplication

Content theft creates a completely different problem. Just as thieves can steal real property, they can also steal content. Undoubtedly, this is why it is called content theft. This brings problems for search engines, as search engines try to filter repetitive content from search results (and from different sites), sometimes making some false decisions about what is the original authoritative content.

In some cases, this is a hidden problem and could have disastrous effects on the rankings. If you are a victim of content theft and want to act, first send a letter to the person who uses the illegal content to suspend and suspend. You can use the contact information provided by the Web site or the contact information in the WHOIS record for that domain name. If this fails, then the mainstream search engine can be found to warn them of content theft.

The following is the URL address of the mainstream search engine responsible for this:

Google:http://www.google.com/dmca.html

Yahoo!:http://docs.yahoo.com/info/copyrighffcopyright.html

Basically as long as a website is to adhere to constantly update original content, Baidu, Google, Yahoo and other search engines have been able to well identify original source of content. What the webmaster needs to do is to keep updating the quality of the site content every day.
