Welcome to the Q&A Forum

Hmmm... feels like I'm misunderstanding part of the question here. To get your AJAX content indexed, your server needs to return an HTML snapshot to the crawler, so the simple (or not-so-simple) answer is to inject a meta robots noindex, follow tag into the HTML of the snapshot, just like you would a regular HTML page. How you do this depends on your technology choice and server configuration, (which unfortunately I probably can't help you much with) If you'd like, feel free to leave a few more details about your particular situation and the solutions your using, and perhaps another community member can chime in.

Hi there! This is Megan from the SEOmoz Help Team.  I'm really sorry that you're running into problems with your OSE exports!  Since this is more of a tools related question, I'm going to open up a helpdesk ticket for you for tracking purposes in case this is a bug.  I'll be in touch with you shortly! Cheers!

Hi wwmind, I was going suggest Xenu, but also Screaming Frog. There's a both a free and paid version. To crawl more than 500 URLs, you'd need to get a license for the paid version. http://www.screamingfrog.co.uk/seo-spider/ The other option, if you can't find all of your broken links, is to redirect them via a 301. Installing a bunch of 301's via .htaccess or another means isn't as good of a solution as fixing your links, but it might offer a more scalable solution. Regardless, best of luck with your SEO!
