Some days ago and a better friend chat site This piece, he suddenly and I said his site appeared a very strange problem, sub domain name under the page included, the main domain name under the Web page has not been included? Looked at his website, I found his main domain name under the page there are some big problems, roughly the following points, It is also the main reason why I think the Web site is not revenue under the main domain name.

1. The main domain name under the Web page does not have what content.

Most of the home page is the navigation, navigation links are sub domain names, the proportion of the picture is very large, navigation and pictures removed, the entire main domain name does not have any page, at that time I ordered not more than 20, even if all included also only 20 pages, not to mention this is impossible.

2. The key words of the website under the main domain name.

A lot of keywords in the main domain Name page content does not appear at all, causing a lot of irrelevant keywords, in search engines, especially Baidu, the general default is cheating, so how the page included?

3. Website main domain name under each page question.

Site title under the main domain name, keyword almost exactly the same, so and each page itself is not the specific content of the combination of points, search engine easily sentenced to cheat processing, the page's collection of natural problems.

In this will not directly say the station name, of course, there are other aspects of the problem, such as the overall framework of the site design and so on. Not one by one, and finally hope that all the webmaster attention to some details, which is to do a point of SEO, and finally I wish all the sites in the new year to do better!

The last to bask in a small station: Http://www.dodocc.com also asked the audit officer a lot of understanding ^_^
