What do you think is happening here?
I replaced the product with a much lower commission ($28.50 per sale) and the conversion has increased. Now it is earning at least 1 sale per day again with the new product but not making the same because of lower commission per sale.
What do you think happened. I tried contacting the product owner but I got snubbed several times.
Although I still add articles from time to time, I now concentrate on an authority site with dozens of different products (planning to promote hundreds to even thousands). I learned a lesson, that promoting just one product is not reliable at all.
