That means if you get your website to a 2% CTR (which is average at best) you should earn 100$ per day with this website. Work on adsense optimization. That's the way to do it. If you don't want to share your website, look at top 10 competitor websites. How are their ad positions, which monetization options do they implement? If they use the same technique over a longer period of time it probably works. Also, have you considered affiliate marketing and/or opt-in lists?
Same here around that much CTR. Have been getting some success with placements though. Now working on more traffic.
it depends upon niche, placement, traffic, ad design and many other factors. some ppl will say its good and some wil say its poor. I will say its really poor , seems 0.01$ cents
Social Networking sites are very hard to monetize, even google is not doing as well as it expected with its myspace deal.
I suggest you try to improve your CTR. Try different ad units. I suggest you use the 336*280 or 250*250 ad unit. This will help to increase the CTR.
Sure I will, till now, I used 468*60 and 160*600 because they fit it, but now I'll try with these once.
