Crawl Errors

[azguy]

Okay, I was just in my Google Webmaster Tools and was looking at some of the stats.

I have 1354 "not found" pages google says.

Many of these URL's are bizarre. I don't know what they are. Others I do know.

What should I do about this? Especially all the URL's I don't even know what they are?

can you use those individually to get to a real page on the site?  or even when you do them manually, do they lead to a 404 not found error?  Links in Google's system come from somewhere - either within a site's architecture that site owners weren't aware of, or from 3rd party sources that got something wrong in how they found or scraped content.  Many of the URLs Google reports show a "links" column off to the right you can click on to see where those URLs are located on the web either on your own site or another...

These errors don't affect you negatively at all, it's more for you to find errors in your site. Follow Alan's advice by looking at the 'links' data and fix the one's that are caused by any coding problems in your site. You will always get a certain amount of bad links coming from external sources, you can either just leave them or if you are finding many links to the same 404 page you can actually recapture that link juice by 301 redirecting them to a relevant page on your site.

Okay, and thanks Alan!!
