For affiliate marketing micro niche sites are very helpful to get sales. Anybody any idea where I can buy these kind of sites legitimately?
Look for them in various private forum or the community boards those who have a buy/sell section. They are not too hard to find.
They can be found in community boards which boards buys and sells them but why would you want to buy them for the first instance? Maximum of those sites are worth nothing they never generates revenue. If you want you can build one it will be way safer.
Once I bought a niche site from a friend whom I met with in a facebook private group.
can you tell me your budget range?
