Before I tell my answer let me say why I don't use my website to gain customers. The reason is because without my website I can not keep up with our sales so I do not need a website.... with that said, I really want to use my site and try to keep up on things in case I ever need to start using it..... This will vary widely for many different sites. You can't just compare CPM rates. How about eCPM? If you don't know what that is... in short since I only have 2 minutes.... CPM is 1 side of the coin while eCPM is the other. Do a search on it if you aren't familiar. Hopefully this helps before you get the conversations started. :)
