When you move a web page from one URL to another, you use redirects to ensure that users and search engines are directed to the new URL. 301 is a permanent redirect. It tells search engines that the page has permanently moved to a new location. 302 is a temporary redirect. It tells search engines that the move is only temporary, so they should keep the original page indexed. Meta Refresh is a type of redirect that happens on the page level. It's not as SEO-friendly as server-side redirects because it doesn't pass the same level of link equity. Canonical tags are HTML elements that help prevent duplicate content issues by specifying the preferred version of a web page.
