I know about meta ads.
If you go to Facebook meta ads and search by company name using "", eg, " abc.com" then u will get all the ads they are running. Copy that URL, go to clay, create a formula ( when u paste that copied link u will see company name in between, remove it and use " company name" columns instead, all links for meta ads will bhe created, after that use claygents and ask him about if they are running ads or not, dm me of u are not able to understand. I will show u examples
