What is the 404 error?
The appearance of a 404 Error on a website can occur due to different causes. Here are some of the most common:

1. External page removed
Often these errors occur from a link that we have on our website and that lead to an external page that has been removed.
2. Internal content removed
On numerous occasions we begin to make changes to our website that imply changes in the URLs, either because we delete the page or because we change some type of configuration that may affect them, as is the case of the "permanent links" in WordPress , which apply changes in the URL structure. When we make a change to the URL, the source URL is lost, so when we try to access we will face a " 404 Not Found ".
3. Incorrect introduction of the URL in the browser:
Although they are the least common, some users enter the URL directly in the browser and can do it incorrectly. Result? The URL, misspelled, will not be found, resulting in a 404 response code (phew, thank goodness that the vast majority of us trust Google for our searches, even to access our own website).

How to detect 404 errors on your website
There are numerous tools for detecting 404 errors , both free and paid. We show you some of the most used:
Google Search Console
Google Search Console is the star SEO tool in this field as well. And also free. Accessing the “ coverage ” report we can easily see which of our URLs are excluded because they were not found (404). The only "but" is that, being Google, this tool only reports Googlebot errors, ignoring the rest of the bots.
