Does anyone know about existence of a code, which would allow to manage Google Adsense ads (on one's website) from one location instead of editing each ads individually? Or at least certain size of ads - in one go, another size - al locations in one edit, etc. I have thousands of pages of blog and 1 to 3 ads per page and now I realize I added them slowly over the years, ad by ad and now when it is time to edit them all, it will take me a very long time. Hmm. Save my ass, please.
You will have to edit them all manually. Or do a search and replace via phpmyadmin Set up something like https://www.revive-adserver.com/ next time
