The function of any redirect is to redirect the traffic of a resource from one of its pages to others. Why is this done? In fact, there can be quite a few reasons. For example, when it comes to moving a website from one domain name to another. Let's say you were the owner of the resource http://site.ru/. The website was nice and had decent traffic. However, for some reason, you were forced to change its name to http://site1.ru/. Someone may ask: "Why do we need a redirect when you can use domain parking?" Indeed, the latter method is easier and, in the opinion of many experts, more effective. Of course, both when using a redirect and when choosing a parking lot, the visitor will see your website. Nevertheless, there is a reason to use a redirect. For example, in the case of a redirect, it is the redirection that takes place, and when parking, both websites are regarded as one resource. Redirect is often used for the so-called domain gluing. This combination allows you to get fictitious PR and TIC belonging to one of the resources and resell the domain for money. Of course, professional webmasters are unlikely to buy this trick, but beginners may do. At the end, we want to give examples of status codes for redirects: • "300" offers you to make a choice • "301" permanent movement • "302" temporary redirect • "303" resource address changed • "304" content has not changed • "305" proxy usage for access • "306" is no longer used. A lot of redirects on the website often harm optimization, try to avoid them and keep them under control if possible. To control all redirects on your website, use Sonar.Network website monitoring. It is very easy to get information about any redirect or error on your website.
