Congrats my friend , do you want to share your secrets and the site name ? i really want to see your site
Easy to do! that guy does not tell! Why? There are 2 way for a guy like him to achieve this: - screenshot + photoshop/theGimp (free way) - he spent 1000$ on Adwords
I don't understand why people ask successful people about what niche they use ? It is all about trial and error. Most of the people I know who do $100+ a day have multiple niche sites and their income is aggregate of all sites. I have yet to know some one personally who has one site and does $100+ / day (yet to know personally - don't mention DP and other sites - I know these sites might already be doing 100+ everyday but I don't know the owners personally).
Congrats, Personally, I may use google Adsense to cover the site costs but have other businesses to do and there is no dubt that you can earn a lot from Adsense but the question is "If you didn't want to share your story what was the point of opening this new thread and showing that screenshot ?" You could expect a lot of people interested to know more about it. Anyway good luck with your site(s)
Nice reader may be, but not a nice sharer apparently! One important thing you learn from reading over here (if you do it good) is sharing with other can bring you a lot... throwing some numbers without any arguments is useless and has no value to me.
