What is URL normalization? A typical case of a nonstandard web site is a page with 3W and no 3W is included in the search engine, resulting in a long list of sites can not do, especially Baidu, many novice will encounter this problem. Non-canonical URL refers to the same content but the URL is not the same, and the normalized URL is a page only a URL to point to it. An example of an irregular URL is given below:

This is a snapshot of an article in the A5 website. These 2 different URLs point to the exact same page, but the URL is different. The above is the URL to use when accessing from the Member Center, and the following is the URL to use when accessing from the article list. I've also checked the Chinaz, and the URLs used for the same article from the Member Center and the regular articles list are unified. For some small sites, there may not be such a problem, but some large functional web sites will inevitably occur.

Such an irregular URL to the webmaster, multiple URLs scattered weights, not conducive to ranking, the search engine waste resources, waste of bandwidth.

Focus on Google SEO webmaster may know canonical tag, this is Google, Yahoo, Microsoft jointly released a new label to solve the problem of Web site normalization, such as: <link rel= "canonical href=" http:// Www.admin5.com/article/20110206/312523.shtml "/> So the code in the URL by the search engine identified as the canonical URL, then for the page other different URL search engine will automatically 301 redirect to the page, 301 is only for search engines, the page does not really turn. I do not want to talk about this, because Baidu does not support this label.

How to solve this problem?

1. For 3W and less than 3W page problems, the recommended approach is to take the domain name without 3W to the domain name with 3W (Google Google Administrator tools are easy to achieve, there are a lot of tutorials online.)

2. If the website is inconvenient to implement 301 redirects, use an absolute URL instead of a relative URL (in fact I think you should use an absolute address at all times).

3. A CMS system with a normalized URL, such as Dede.

4. Communicate with programmers to avoid irregular URLs as far as possible.

Do search engine optimization is not a simple content plus outside the chain, there are a lot of small problems need attention, http://www.sffb.net is willing to learn and discuss together.
