What Is a Redirect?
A redirect is a server instruction that sends users and search engines from one URL to another. Redirects help preserve access when a page address changes, a site structure is updated, or duplicate URLs need one preferred destination. The redirect type determines how browsers respond and how search engines interpret the URL change.

- The redirect type affects search engine interpretation.
- A redirect is not the same as a canonical URL.
How Redirect Works

A redirect works when a browser requests one URL and the web server returns instructions to visit another. The browser follows the instruction and loads the destination page. Search engines also process the response, which helps them understand whether the move is temporary or intended to remain in place.

A permanent redirect is commonly used after a page address changes, while a temporary redirect suits a short-term change. The server response carries the redirect status, and the destination URL should match the page a visitor expects. A canonical URL communicates a preferred version to search engines but does not send visitors away from the requested page.

Expert Note
When we review redirects, we trace the old URL to its final destination and check for chains, loops, and irrelevant targets. We also compare server responses with the site structure and sitemap so changed dental service pages remain clear to visitors and search engines.
