In the backend DNS parsing interface of Alibaba Cloud, you can see that URL forwarding is divided into explicit URLs and invisible URLs. What is the difference between them?
Which one is better for SEO, explicit URL or invisible URL?
1. Explicit URL: When the domain name a.com is entered in the address bar of the browser, the website will be redirected to b.com after opening; in fact, it is the way of 301 or 302 redirection for URL forwarding
2. Invisible URL: when the browser Enter the domain name a.com in the address bar. After the website is opened, the browser address bar is still a.com, but the content of the website b.com is displayed. In fact, the use of iframe framework technology to hide the target address
Crawlers and spiders don't like iframes, and explicit URL redirection weights can be passed, so from an SEO perspective, explicit URLs are more conducive to SEO.
Important: Whether it is an explicit URL or an invisible URL, the domain name needs to be filed. Taking Alibaba Cloud as an example, if the domain name has not been filed, adding a URL forwarding record to the domain name resolution will prompt "Request failed URL filing exception".
