is a 404 error
Error 404 is an http status code that indicates that we are using the indicated web page.
This error code has been returned by the server where the web page is hosted, and in theory, the search engines do not index the content of the page, I say in theory because if the page was indexed Google may take days sometimes even weeks to eliminate that search engine result.
Surely I can tell you that it is the most common error in any web page or blog and that it does not exist for that, that there is no website that is free of the happy 404.
Why the 404 error occurs
The 404 is produced by different causes, but these are perhaps the most common:
1.-External link to a web page that no longer exists. I had a teacher who told me that many of the 404 errors in the future, I personally think we should do a good job of detecting and dedicating a few minutes every week or every 15 days to detect and clear these external links.
There are different reasons why we have an external page to be there but the most important thing is that “the host does not exist”.
2.- Internal link to a page that no longer exists. This error 404 may be less than usual but sometimes we have to delete it from the website and forget about 404 errors.
Another common error 404 is to link the website of the website what causes it generates the error.
3.- We misspell the address in the browser. Many less usual and common but it is also when we type the url manually in the browser.
4.- False error 404. Not because we receive one of the 404 errors means that it really is, to verify it. I recommend that you do that web page as Google does and certify that the http error exists.
Another simpler method is to do a simple check and visit the URL.
5.- Deleted page that reports a 404. This case is the least known if you do not use the tool Google Webmaster Tools is very difficult to realize, and it happens when you delete it on your website that is linked in a way internal, that is, from your own domain, or which, in addition to having a 404 link to our website we will also be missing link juice.
Are 404 errors for SEO?
According to Google, in most cases they are not:
