With a 301 redirect, the page being redirected receives the entire link value (ranking power) from the original page. The HTTP status code 301 is the one that is used for this kind of forwarding. When it comes to implementing redirects on a website, 301 forwardings is generally considered to be the most effective method.
The process of rerouting traffic flowing from one URL or page to another URL or page at a different destination may be accomplished in a straightforward manner by using a 301 redirect. When you delete a post or page, for instance, this information is removed exclusively from your own website and is not removed from any search engines.
The article or page continues to be shown on search engine results pages (SERP) for an extended period of time. If someone clicks on that specific link, which does not exist on your website, you will get a 404 error. So, this is the situation in which the 301 permanent redirections might help you solve this problem. Use the 301 redirection function, which may be found in a variety of plugins.
A 301 redirect notifies users that the page they have requested has been permanently relocated to the Destination URL or page, and it assists in the transmission of traffic from the Requested URLs in a way that is beneficial to search engines. When you create a 301 redirect, you are informing search engines that the material formerly located at the Requested URL has moved permanently to the Destination URL, where it may now be accessed.
This information is also shared with search engines when you use the 301 Redirect. When a Google bot visits your website again in the future to update its index, it will notice not just that there is a redirect, but also that the redirection is being treated as permanent. After that, it will include the newly added page in its index.
In terms of link equity, Google does NOT pass 100% equity through 301 redirects because doing so would enable spammy SEO practices. In point of fact, just like with backlinks, the level of PageRank decreases through each node in the link graph, which means that it changes from URL to URL within the link graph.
As a result, you need to give serious consideration to the question of whether or not a 301 redirect is totally required or wise. When you have made the decision that you need to migrate the design of a website or migrate the domain name, you should first carefully consider the risk-to-reward ratio, and once you have done so, you should utilize a 301 redirect.
Also, you should never redirect all of the URLs to the homepage if those pages are unnecessary and need to be deleted. Instead, you should always attempt to send PageRank in a meaningful fashion to material that is semantically aligned, and you should only do this if you really have to.
