Had a look on flippa awhile ago and came across a health site that sold for around $17000. The site claimed to make 4-5k pm and was an affiliate for two health products. The traffic for the site was paid traffic (PPC and PPV). I had a look at some pre made websites and found a few sites similar to the one sold on flippa and wondered if he really did make 4-5k with his site. He had personally sent the advertising spend ($800-$1000 pm) and conversions of the product.
Just wanted to know if pre made niche websites are worth using?
