: How to fix Google 404 not found Crawl Errors? I was checking on Google webmater tool for my blog site to see if there's any indication on why my blog traffic decreased to half in one day

There's a blog post on this topic on Google's Webmaster Central blog, it covers most of the questions around 404 errors.

Generally speaking:


If these are pages that you removed, then the 404 HTTP result code is fine.
If these are pages that changed addresses, then you should 301 redirect to the new addresses. How you do this depends on your setup, for Apache-servers you may be able to use the .htaccess file for this.
Unless these are pages that used to receive a lot of traffic from search, these 404s won't be the reason for your site's traffic dropping like that. Google understands that the web changes and that URLs disappear - that is not a reason for Google to stop showing your site.


So my recommendation would be to check the URLs that are listed as 404 crawl errors. If any are important, then set up redirects to the appropriate new URLs as soon as you can. If none of them are important, then keep this in mind as something worth cleaning up when you have time, but focus on the rest of your site first. Often drastic drops in traffic are due more to the general quality of the website, so that's what I'd recommend working on first.
