Pages with and without www in URLs

[robiulhasan]

URL normalization is the process of unifying different URLs that display the same content . Examples of cases where normalization is required include:

Pages with and without index.html at the end
PC and smartphone pages
Each page of sort results such as "by name" or "by cheapest" on a list page vp financial mailing leads of an EC site, etc.
For example:

Even if the URLs of each page are different, the content of the page is almost the same. In this state, each URL is treated as a separate website, which is very disadvantageous in terms of SEO. This is because the number of visitors and inbound links for each URL are treated separately, and the SEO evaluation of the site is dispersed.

To improve this situation, each page can be aggregated into one URL using 301 redirects, so that multiple pages are treated as one page. This is called canonicalizing the URL.

2) 302 Redirect
302 redirect is a process to temporarily transfer a page.
It is effective when you want to temporarily move the URL of a page, but it is not often used in practice.
