I've been running, to minimal avail, ads that take visitors to my homepage. Only ~6% of them who get here this way even view a product, and only a few more than that view a collection. I don't like how this pans out with PPC advertising.
If I switch to ads for individual products which take visitors directly there, does that generally prove to be a better return on investment? Also, what kind of google ads budget can it be done on?
