Mass 404 Checker?

[Andy.Drinkwater]

Screaming Frog Spider does a pretty good job...

As simple as enter the URL and leave it to report back when completed.

Xenu Liunk Seuth - its free and will go through internal links, external or both, it will also show you where the 404 page is being linked from.

Also can report 302s.

Agree with Screaming Frog. It's more comprehensive than **Xenu's Link Sleuth. **

It costs £99 for a year but totally worth it.

I had a few issues with Xenu taking too long to compile a report or simply crashing.

Cheers Andy & Kyle

Problem with this tool as it works similar to Xenu which is great for making sure your current navigation isn't causing problems.

My problem is there are over 15k links pointing to all sorts of articles and I have no idea what's live and what's not.  Running the site through that tool won't report the pages that aren't linked in the navigation anymore but are still being linked to.

Example is manually checking some of the links I've found that the site has quite a few links from the BBC going to 404 pages.  Running the site through Xenu or Screamy Frog doesn't find these pages.

Ideally I'm after a tool I can slap in a load of URLs and it'll do a simple HTTP header check on them.  Only tools I can find do 1 or 10 at a time which would take quite a while trying to do 15k!

To be honest, I don't know anyone who has bad things to say about Screaming Frog - aside from the cost, but as you said, really worth it.

However, it is free for up to 500 page crawl limit, so perhaps give it a go?

Ollie, if I'm understanding your question correctly, the easiest place for you to start is with Google Webmaster Tools. You're looking to discover URLs of pages that used to exist on the sites, but no longer do, yes?

If you click on the Health link in left sidebar, then click Crawl Errors, you get a page showing different kinds of errors the Google crawler has detected. Click on the Not Found error box and you'll get a complete list of all the pages Google is aware of that can no longer be found on your site (i.e. 404s).

You can then download the whole list as a CSV and start cleaning them up from there.

This list will basically include pages that have been linked to at one time or another from other sites on the web, so while not exhaustive, it will show the ones that are most likely to still be getting traffic. For really high-value incoming links, you might even want to contact the linking site and see if you can get them to relink to the correct new page.

Alternatively, if you can access the sites' server logs, they will record all the incoming 404s with their associated URLs as well and you can get a dump from the log files to begin creating your work list. I just find it's usually easier to get access to Webmaster Tools than to get at a clients server log files.

Is that what you're looking for?

Sorry, one additional - since you mentioned using Open Site Explorer...

Go to the Top Pages tab in OSE and filter the results to include only incoming links. One of the columns in that report is HTTP Status. It will tell you if the linked page's status is 404. Again, just download the full CSV, sort the resulting spreadsheet by the Status column and you'll be able to generate a list of URLs that no longer have pages associated with them to start fixing.

Wow nice one mate did not know that in the Top Pages tab that is perfect! I'll remember to click around more often now.

I found this tool on my adventures which was exactly what I was after: http://www.tomanthony.co.uk/tools/bulk-http-header-compare/

Also cheers for your walkthrough, having problems with the site still bleeding 404 pages, first thing first however is fixing these pages getting high quality links to them

Cheers again!

Glad I was able to help!

It would be great if you could mark the answers you found helpful, and mark the question as answered if you feel you got the information you needed. That will make it even more useful for other users.
