Do not ignore the negative effects of www in the website domain name

When a user visits a website, such as the network can input www.huazon.com or huazon.com, so that can be normal access to the site, normal use, and will not feel anything wrong. And as webmaster friends, do you ever think this will affect SEO optimization effect? In the website promotion, do you promote the homepage with www or not with www? What is the outer chain of your release? How's your weight lately? Has your Baidu snapshot been updated? Did your website do 301 redirects?

If you are confused about the above problem, then you should pay attention to, your site is very dangerous, at any time will be http://www.aliyun.com/zixun/aggregation/8766.html "> Baidu down the right, resulting in a decline in rankings."

The author recently also noticed this problem, to the public network as an example to you talk about:

The following two pictures are a recent day Baidu snapshot:

Baidu Snapshot with www

Baidu Snapshot without www

Why is this happening?

This is because this site did not do 301 redirects, in search engines, different URL of the domain name is not the same, so the site is included 2 times.

You go to the query below with www and without the WWW domain name and outside the chain of the situation, is not the same ah?

This is inevitable, because the search engine will this different URL classified as a different site, that is two sites, where I do not recommend that you always tangle with the WWW and without the www included problems, because you tangle also no use. Because we rarely optimize the URLs without WWW, also will not give him to increase the chain, and even the content link will not increase, and then talk about what impact, say really do not take the WWW under the general situation is not to participate in keyword rankings, so you do not have to tangle him, our preferred domain optimization is generally with WWW web site.

Generally not with the WWW included are better? In fact, this problem is not included in the problem, but the weight of the impact of the problem. Because no www is in the normal state of the collection, because he has not been external links and internal links to the weight of the problem. We all know that with the WWW often have to be bothered by external links, because we have to use the WWW to do keyword rankings, so we have to work to increase external links and increase internal links, so contradictions are coming.

Do you need to do 301 redirects?

I suggest or is necessary, so that the uniqueness of the domain name, so that users can remember our preferred domain, the non-preferred domain 301 directed to the preferred domain is very necessary practice, and in the website promotion, can guarantee the weight of the site, the site rankings, will not lead to decentralized weight.
