I have a website (example : abcstore.com) that is about Gifts for men, and I am promoting amazon products on it. But it is really really hard to get sales as far as "Gifts for men" is a pretty mass topic to cover up. I would say, I had got about less than US$10 sales over a year via that site.
I had noticed that many guys are saying that to target niche market, like products only. For example : Laptops, Micro oven, Coffee makers or etc. I am sure that is worth to have it, because the conversion rate may be high specially from Google traffic.
Now my question is, If I decided to get go for only one product and promote using same site called (example) abcstore.com. Will it be harder in terms of promoting? (Reason is, already I have many backlinks pointing to the site using gifts for men related keywords)
I know, I can go for new domain and promote it, it will be easier, but I love my old domain and I don't like to give it up without earning any sales using that domain
