Hi , I can see some site sales 100 or 50 niche ready adsense web site , one thing that I do not understand is ; do I have to buy 100 domain to promote these niche sites? any comment appreciated.
Your question makes no sense, are you asking if you need to buy 100 different domain names to make 100 different niche-styled websites? I would never recommend getting that far in over your head, I say start with 1 or 2 really good ideas for websites and then draw traffic to them. From there, once you start building more and more traffic, you'll see great results with AdSense.
Better go with 3-4 sites and pick keywords on those micro niches and make pages about them on your main sites and optimize those pages for traffic. 100+ sites and managing them?? = Some serious Pain in A**
I recommend you to start with a single website and try to get decent traffic to it. When you feel confidence in this website you can start a new one. If you plan to buy 100 niche sites for the link wheel, then it is up to you.
I really wont waste my time. Just build one website that can yield you $1000 a month, rather build 10 websites that can earn $10
it's really ok if you can create 100 sites as long you know how to monetize it. dont just focus on adsense. Try affiliate programs like amazon, cj or ebay.
