True or false I'm not quite sure but what I have seen is some product posts that have no buying keyword like buy, cheap or price in post title or content will lead to visitor just go and close the page, no any action to click the affiliate link.
Some people may click the link just want to see more details, sure that you got cookie and may get the sell but this's very few and almost not.
Affiliater needed the people who want to buy and intent to seek the product, compare and buy, unwanted visitor just want to look around or collect the information. Action should be done at that time or the next day at less.
I would consider to put the buying keyword at somewhere, that might not be in post title, at this time still not finalize yet, need to give myself a bit to learn more....
