Unfortunately none of them ever did and if they did rank in google they were for search terms nobody used. Knowing what I now know about search engines I am aware that this whole experience was a very stupid and expensive move on my part.
My goal however has not changed - I am always looking for sites that sell physical products (Amazon OK) that already have or could easily get passive traffic. I also buy traffic that is looking to buy, but sources for this are scarce in my experience.
If anybody has any experience with good purchases of traffic or good DFY sites can you post here so that we can all benefit.
