How To Find Businesses For Advertising ?
I want to go after businesses that are already paying for some form of online advertising. I know there are a lot of local lead scrappers out there, but I can find one that looks for business already buying advertising. I understand that is a broad statement as there are online yellow page ads, eBay classifieds, PPC etc. The best I could find is for PPC is geo.semrush.com which is expensive (the list was $1100). Any ideas on how to find businesses that are already spending money for online advertising?
