404 error message on Joomla - how to find and fix broken links?

If someone visits a page that does not exist, then a server will return a 404 not found error. Broken links may have very bad impact on your website's reputation, frustrate your visitors and result in smaller number of visits. That is why it is so important to avoid 404 error pages as much as possible.

Of course not all 404 errors messages on Joomla site are bad. If you have deleted an article or product because it was no longer relevant on your website, then 404 error for such content is fine. Google will simply remove that page from the search results after some time.

The things are different when 404 page not found error occurs for a content that is still present on your website but under a different URL address. This may happen, for example, when you update the article alias or category.
