Actual link ads still display on my website, so the revenue is still being collected but not paid to me, I suppose. Yet my website has tens of thousands of pages and I am unable to remove them all so quickly. May take me a few more months to do that. Sweet deal for Google to make money from the ads that I don’t get paid for any longer.
Are you saying you see actual link ads on your site or are you seeing activity in your reports?
If the link ad units were set as responsive they should now automatically show display ads so there should be no reason that you wouldn’t still get paid for them.
However if the link ad units were set as fixed size then those do need to be removed but sorry at the moment I don’t know if they should still be showing ads or not if the code hasn’t been removed.It depends on your site and how it is configured.
For instance, you can use a text editor to search for the ad unit in all HTML files and remove all ad units in one go. This works if you can download your webpages to your computer, batch find and replace the ad unit locally on your computer, then upload the files to the server again. If you do this, ensure that you have a back-up in case something goes wrong.It’s certainly a pain to remove all those ad codes, but can’t you batch find and replace?
