Every webmaster knows, with www and without the difference and contact with WWW domain name, most stationmaster also did 301 redirect. Redirect the domain name 301 to the primary domain name, which can effectively pass the weight. The method of weight transfer is related to the algorithm of search engine. It seems like a cliché that how you can achieve the maximum weight transfer by directing. But what does URL forwarding and redirection have to do with it? This paper mainly explains the impact of URL forwarding and 301 redirection methods on weight transfer.

URL forwarding function in the domestic domain registrars are listed as "prohibited" one of the functions. According to the relevant regulations, this function is limited to use. URL forwarding is not a mystery, its most basic use is to link the new domain name and existing sites. The reason for the ban is that many domain registrars use this feature for forwarding to illegal websites, and a large number of "highly imitated domain names" are forwarded to illegal websites to squeeze profits. But this is not to say this function and stationmaster is missed. There are two ways to use this feature, the first way is to register in the foreign Domain name registrar, admin domain name can implement URL forwarding function; the second can host (or change NX Records) to a domain name management system that supports forwarding functions. How to do this is not covered in this article. If you have any questions, please contact Xiu Meng site long. When you use URL forwarding, you need to be aware of an issue: implicit forwarding and explicit forwarding.

Implicit forwarding: Forwarding is similar to the CNAME alias, the DNS server actually forwards the data, but the user does not see the forwarding effect when fed back to the browser.

Explicit forwarding: The forwarding method is similar to redirection, and the DNS server actually forwards the data, which is also visible in the user's browser.

Implicit forwarding is disabled by most managers because it hides real domain names.

Let's say 301 redirects. 301 redirects mainly modify the way of Apache, Ngix, IIS configuration, modify jni.so and modify. htaccess. Data capture concludes that either modifying the server configuration or using the. htaccess, the data received is the same. In other words, there are no two ways to distinguish between sending and receiving data. However, if you crawl the. htaccess file, you can match the redirection method with the regular expression. Content about 301 redirects is also not covered in this article.

The focus of this article is to understand URL forwarding and 301 redirects. When the weight is passed, the search engine transmits the value according to the feedback speed. Search engines are a scoring standard for simulating user experience, and if data feedback is too slow, the user experience is considered poor. After the study found that the speed of URL forwarding is the fastest, provided that there is a good DNS, followed by the modification of the server configuration mode of 301 redirect; the slowest is to modify the. htaccess file.

Principle: URL forwarding is the data in the DNS level of transmission, high efficiency, small amount of data, fast; Modifying the local server settings is faster than modifying the. htaccess file, because if. htaccess, the server receives the data and accesses the file under the directory, and the cost of the access step is much higher. The server settings are exempt from this step by taking effect directly.

The conclusion is that for weight transfer, URL forwarding effect is better than modifying server configuration, both of which are better than modifying. htaccess.

Another thing to note is that explicit forwarding for URLs is divided into 301 explicit forwarding and 302 display forwarding. If 302 explicit forwarding is not passed the weight value. Similarly, URL implicit forwarding is not the right value, and may even be the search engine K station.
