Google Webmaster Tools gives "404 not found" although page exists

M开发者_Go百科y website is submitted to Google, but when I search for "rifflex", I don't get the homepage. I just get all the other pages of the website.

When I go to Webmaster Tools, I see in the "crawl errors" section that the homepage is giving a 404 not found error. However, when I visit it normally, it exists and gives no errors. When I try the "Fetch as Googlebot" tool, it also doesn't give an error.

A few questions you have to ask yourself:

• Do you do any kind of user agent redirection to mobile sites?
• Are you using any content management system?
• Have you entered anything in Robots.txt?
• Do you use meta tag's (robots)?

Check out the IIS Search Engine Optimization Toolkit. You can use it to perform easily a full analysis of your website. Installation is very easy using the Web Platform Installer.

If you have still problems, you can ask your question too on the Google Webmaster forums
