How to find all 404 errors of a blog quickly?

[diamondhead]

I was using blogspot. And moved my blog from it to wordpress. Now many urls are showing the 404 error. How to quickly find all of them and then deal with it?

The most easiest way to deal with it is to create a site-wide audit. To run that you can use any tool you like such as semrush or ahref or moz. If my guess is correct moz even let you do it even if you are only signed in as a trial user.

So, any audit tool should do it??

[supaul]

Not any. But any good audit tool should do it. Preferably the paid ones.

Which will be good for a all-in-one tool? SEMrush or Moz Pro?

Please check manually. That will be better.

This is the easy way to use Google search console to find all 404 pages and fix them. To find the list of all 404 pages, you can log in to the Google search console account and click on Crawl errors under diagnostics. Click on not found, and you will see a list of all the links resulting in the 404 error.
