How to find 20 hidden 404s

[BobGW]

Hello,

We have like twenty 404s left to find. How do you find these when:

1. They don't show up in Google Webmaster Tools

2. They don't have any other internal or external pages linking to them.

3. They don't show up in site:domain.com (We have 9000 pages and only 600 show up - I fixed those out of the 600).

4. They are probably causing high bounce rates.

5. They're not in the sitemap

Thanks!

You can try crawl the site using screamingfrog, make sure you  check the box “Check Links Outside Folder” in the spider menu.

The free version checked 397 URLs. Will the purchased version check all 9000?

[Felip3]

Yes I just run a craw for 500 000 urls

[BobGW]

Yes, but if it only check 397 in the free version is it going to stop there in the paid version as well. Just making sure.

Also, will it catch everything?

[Felip3]

Right in the paid version wont stop! You can see in their website that the limit of urls will be remove once you buy the license.  http://www.screamingfrog.co.uk/seo-spider/licence/

It should catch everything, maybe you can contact their support just to make sure, they are very good on support over twitter.

You should be able to crawl the entire site without increasing the RAM, once you buy the paid version.
