4xx Client Error

[IPIM]

I have 2 pages showing as errors in my Crawl Diagnostics, but I have no idea where these pages have come from, they don't exist on my site.

I have done a site wide search for them and they don't appear to be referenced are linked to from anywhere on my site, so where is SEomoz pulling this info from?

the two links are:

http://www.adgenerator.co.uk/acessibility.asp

http://www.adgenerator.co.uk/reseller-application.asp

The first link has a spelling mistake and the second link should have an "S" on the end of "application"

Is your site verified in Google? Try logging into Google Webmaster Tools and looking at the 404 report there. It often will list the incoming link for a 404 error.

then the only other time I've seen this happen was from inbound links that Google found on other sites.  You can try searching Google itself, however you may or may not be able to discover where they exist.

Nope, just checked the sitemap and not reference to them on there either.

Thanks I will check the site map, I have done a find all search and canot find any reference to those URL's anywhere in my site.

Where does SEOmoz pull this info from?

Google picks up links several ways.  If you are 100% sure these links are not in your own site somewhere (even on a single page, either intentionally or accidentally), check your sitemap.xml file, but be aware that they also pick up links that come from 3rd party web sites.

If you can't find the source, consider setting up a 301 redirect to resolve both of them, or alternately don't worry about them if you only have 2 listed and your site is otherwise doing well.
