Adsense is not always the best

I have a website related to some anti aging hormone. This site is around 3 years old and makes around $600/month consistently with adsense from last one year. This site has top3 ranking on most search engines fir some very good keywords and gets around 1000 uniques a day. So, with those 30,000 uniques and $600 in adsense, I was happy with $20 eCPM. Who wouldn’t I be? It looks like good eCPM. So, I was very happy with this site. Till two days back.

So what happened two days back?
I received an email from one of my site competitors, that he is willing to buy my site (they saw the search engine rankings for it). I told them that the site is not for sale. Then, they gave me an offer which was very difficult to refuse. An offer of $25,000 for the site. I was shocked. Is my site that worth? How he is going to monetize the site making that much money? All these questions came to my mind.
By first seeing the offer price, I was just about to sell it. But then I thought, why not try and see what he is going to do with the site. I can do that myself and see if my earnings can be increased from this site. Thats it, thats where I started researching the related sites and found that most of my competitors are not running adsense but running some affiliate links which pays very good (upto $100 per sale).
I put those affiliate links EXACTLY 48 hours from this post (exactly two days back) and here is what stats I see for those 48 hours:

 So in 48 hours, thats a total of $797.52. So if I keep earning that sort of money everyday, that would be around $11,962.80 per month from this site alone. Even if I take the figures little down to $250 per day (instead of current $396.26), I should be making at-least $7,500 per month from this site, which was only making me $600 per month through adsense http://www.jimkarter.com/wp-admin/post.php?action=edit&post=127
Loading…till now.
So, adsense is not always the best way to monetize your website. If you can the right type of affiliate programs which pays good, you can surely earn much more.
So, did I sell my site for $25,000? You know the answer. At the end of month, I will update you people how the month went.
So, whats next?
As of now I have kept the adsense on the site. I will keep them for next 5 days more (total of seven days). Then I will remove them for next 7 days and will compare my affiliate earnings from these two weeks. That will decide whether I should remove adsense completely from the site or not. My feeling says, adsense will go. What do you say?
