Hi. I am in problem. In google webmaster tools showing 17 url not found (404). but there is not any these file in my sever, I have checked properly. what would be happen??
In google webmaster tools there is an option to view the site map that google sees, might be a good idea to have a look at this as for some reason the missing files are located in this site map.
If Google webmaster showing 404 URL that mean those URL must be in you site. From any of page that 404 link given. If your site has less page than check all page manually. If you have more pages than you have to use one software called Xenu. http://home.snafu.de/tilman/xenulink.html here is given link to download free. Xenu analyze your pages from your site and also show from which pages that 404 link given. Try it and let me know if any query you have than.
