The products I was promoting were seasonal so as those products are not available anymore websites don't of course can't convert. However if we use an indicator when those products were available it actually converted very well. I was so shocked at first with the results. From that experience I learned that you can sell "anything" to people. The best part is that I used those pages as landing pages for Pay Per Click campaigns and results were even more incredible. CTR was incredible and CR was also very good but we also had some luck with some factors at that point also those offers that are not available today in this way.
I was so busy with other things that I had to leave that strategy but I am thinking to start it again with of course few tweaks and improvments and on new products.
