Most of my sites have all of the ads units that are allowed in adsese, affiliate links, chitika etc. What do you guys usually do, what works better, more ads and more money or less ads and a better user experience. Will providing a better user experince generate more money in the long run, or should I continue to make more money by putting lots of adsense in my websites?
It depends on the niche your in/ROI If i where you I would sell my own digital product(s) and keep all the profits. With adsense google/ product seller have to profit also.
You need to decide on which way you want to go. Either try to make money selling affiliate products, or try to make money with adsense. Don't make the mistake of trying to do both with one site. Obviously, if you are going the affiliate product route, the only exit off the page you want is to the payment page. Make sense?
