Unbelievable! If its true, its great for you! If you manage to get so many hits, how do pay for your bandwidth, content hosting etc? Your site must be a giant portal. It can certainly not be a 1-15 pages static limited content site focused on a single niche. How do you make profit from this site otherwise? I am very curious!
I dont it will be. What i suppose it not unquie hits. Let us know your figure. All the way if your ctr is high then adsense is really worth
Of course u can use adsense unless you are having a site which against adsense TOS like adult and etc
If this is correct and you are getting those figures per week why just stick with adsense if it was me i would start to take full advantage and not miss the opportunity and add other revenue streams from it.It would make sense.
