How effective is Crawl DIagnostics in determining crawlibility?

[waltergah]

Is Seomoz crawl diagnostics useful for determining what pages Google has a hard time indexing. One of the problems with my site is that it uses JS and Flash and I know Google isnt too keen on that. Can Crawl Diagnostics accurately tell me if there is too much of something and therefore Google is having a hard time crawling?

I want to be able to know if JS or Flash is hurting any of my pages in any way. I provide good content and I want to make sure Google can pick it up.....Is this too much to ask? Is there anything out there for this?

Hi Kyu,

Unfortunately, our crawler does not report if there are issues crawling your site due to JS or Flash, as it is actually unable to parse either of those languages so it does not process any information in those languages. Google's crawler is much more sophisticated than ours, as Host1 points out, so they may be able to parse your site and index it more thoroughly than we can.

Please let me know if you have any other questions.

Hi Kyu,

Host1 is correct about Google. You most likely don't need to worry about your Google index.

As for our crawler. Roger doesn't like Java or Flash so you may see your index and crawl diagnostic with us be hindered a bit as such.

Thanks!
Joel.

I quote:

Googlebot can index almost any text a user can see as they interact with any Flash SWF file on your site, and can use that text to generate a snippet or match query terms in Google searches. Additionally, Googlebot can also discover URLs in SWF files (for example, links to other pages on your site) and follow those links.

We'll crawl and index this content in the same way that we crawl and index other content on your site—you don't need to take any special action. However, we don't guarantee that we'll crawl or index all the content, Flash or otherwise.
