Crawl errors with 403 error code on Google Webmaster Tools

I’m always seeing this error on my GWT account. The error url given is not a valid link on the site. I believe there should be some faulty link or typo error somewhere on the site. How can I find the broken link on my site and fix it, is there any tool? I’ve try with Dreamweaver and Xenu but both also cannot detect this faulty link.

I would appreciate any help from you guys, thank you.

Don’t those stats show you where the link came from? I use AWStats, which usually shows the origin of the link that led to the 404. It’s usually on some spammy site that is just trying to get backlinks to their own site.

Hi Ralph, thank you for you time and advise.

Nope, there isn’t show in details where the link from on GWT account. You can click on the attached picture above. I suspect this invalid link is somewhere on my webpages with typo error…Do you know how can I track whereabout this faulty link?

403 is a forbidden error - have you checked your robots.txt file to ensure you have not blocked crawler access?

You could also try fetching the page as Googlebot to see what response you get.

My robot file does not blocking any files/directory. We use to fetch as googlebot and it showing 302 code. But, on WMT it showed crawl error of 403 detected on July 6, 2011, any idea, any help, please…

This is how Googlebot fetched the page.
