Is it good to redirect million of pages on a single page?

[vivekrathore]

My site has 10 lakh approx. genuine urls. But due to some unidentified bugs site has created irrelevant urls 10 million approx.  Since we don’t know the origin of these non-relevant links, we want to redirect or remove all these urls. Please suggest is it good to redirect such a high number urls to home page or to throw 404 for these pages.  Or any other suggestions to solve this issue.

I would go 404's (and let them die) as I dont think those have any good content on them since it was just generated.

Redirecting them wont really do much.

If for any reason you are seeing traffic flow to these pages then i would redirect if possible.

I would throw HTTP 410s for them all if they don't get traffic. 410 carries a little bit more weight than 404s and we're not talking about a small number of pages here. I wouldn't redirect them to the homepage as you'll almost certainly get a ton of "soft 404s" in WMT if done all at once.

If they are getting traffic, then it'll be a harder job to unpick the pages that have value.

Hi anirbandas,

10 million are a lot of pages ... First of all, still researching and double check to see which is the intent of these links.

You can do any of the options that you have been recommended above, or monitor these links and if you see something strange disavow tool using Google.

Good luck

If you search on youtube you may find a video of Matt Cutts where he is saying redirect a million url overnight to the same page would rise a flag in the anti-spam team and lead to a manual review. If you have nothing to fear and you believe your redirects are legit you don't necessarily have to be scared.

But if the links are due to a bug, I guess they have no juice to pass, so why redirect?

I would also say you can also disavow those links to google - would take a good amount of your time though.

If they were recently randomly generated by some errand code, you can let them die and 404. The only time you want to redirect a page to another is if that page 1) is getting traffic or 2) has backlinks. Since you're dealing with a code error, those two are very unlikely and you can be confident in just killing the pages.
