Here to some novice sweep a blind, a lot of people ask me some of the links to the question always ask the outside chain (external link) is more than will be dispersed site weight, I gave the answer is, not. It is because the weight of the site is passed to share, so there is no dispersion or division of the weight of the said, so as long as the normal range of non-cheating means to increase the site outside the chain (external links) or the chain (reverse link) way on the site without any harm. And we do 301 redirect from the search engine optimization point of view, is to let all the site domain name weights are passed to the same domain name, let the weight unified. Such weights point to a domain search engine will understand the site to do redirect domain name is the site's main domain name, and give the highest authority. Below we will be in combat Operation PHP website system 301 redirects.

Our goal in this actual combat is to enter www.xx.com or xx.com or other domain names that are resolved to the same site in the browser to www.xx.com automatically.

Here's how to do this:

The first step is to implement redirection through the following PHP code.

Create a new file named "do301.php" using the "notepad" program we have on every computer (the name can be defined by itself). Save the exit after entering the following code.

-------------------------------does not include this row------------------------------------

Header ("Location: [Url]http://www.sjz-banzheng.com/index.html[/url]");? >

-------------------------------does not include this row------------------------------------

Note that after the input code must be changed to the above link address to your site as the main domain name address, otherwise it will be directed to Shijiazhuang to do this site.

The second step, the do301.php file uploaded to the server space, the process as a webmaster everyone should be able to master, here do not do too much elaboration. However, it is important to note that the do301.php file must be uploaded to the root directory of the site.

The third step, the do301.php file is set as the default home page file, this step needs to be set up in the website Space Control Panel. If the purchase of server space is required through the server Space Control Panel and account password for landing, and then found in the "Modify the default home page" The words of the link or interface to modify, then you will see that there is an input box is everyone familiar with the file name, index.asp, Default.php and so on. Enter do301.php in the front of the input box. Don't forget to make sure you quit again.

The third step, the input of the site's domain name for testing, if the input of several resolution of the same domain name can be directed to the same domain name under the direction of success. If the change of domain name does not occur in the browser address bar, the orientation is not successful, then you need to check the PHP code you entered.

I believe you can see here will understand, do 301 redirect is to make the site unified weight, and can let everyone through the same domain name to find the site is more conducive to the promotion of the site and publicity. 301 redirect is a very simple and very practical optimization skills, I hope we can understand the essence and meaning, facing the increasingly fierce search engine today to master a method of adding points will make our work efficiency improve a lot.
