- So is it niche marketing?

- Are all your websites revolving around the same niche?

- How many do you deploy for particular keyword and its long-tail keyword?

- How many years/months you spent on keyword research? I mean when did you eventually ended up on this niche?

- All your income is just Adsense? or Affiliate marketing too?

- All yours websites are ranked #1 on SERP or few just somehwere on page #1?

- Is your traffic source completely organic?

- How much of black hat SEO involved?
