Welcome to the Q&A Forum

Hi guys,

So I'm working through a large dataset of 404 errors and trying to clean up the site's crawl-ability. A piece of the puzzle I can't seem to wrap my head around has to do with AJAX endpoints. It looks like GWT thinks these are URLs that don't exist and, therefore, is reporting them as 404 errors.

Anyone experience this before?

Thanks for the thorough response Chiaryn! I figured as much but wanted to make sure I wasn't overlooking anything.

Hi guys,

I have a question in regards to the duplicate page titles being reported in my crawl diagnostics. It appears that the URL parameter "?ctm" is causing the crawler to think that duplicate pages exist. In GWT, we've specified to use the representative URL when that parameter is used. It appears to be working, since when I search site:http://www.causes.com/about?ctm=home, I am served a single search result for www.causes.com/about. That begs the question, why is the SEOMoz crawler saying there is duplicate page titles when Google isn't (doesn't appear under the HTML improvements for duplicate page titles)? A canonical URL is not used for this page so I'm assuming that may be one reason why. The only other thing I can think of is that Google's crawler is simply "smarter" than the Moz crawler (no offense, you guys put out an awesome product!).

Any help is greatly appreciated and I'm looking forward to being an active participant in the Q&A community!

Cheers,

Brad
