hi , can i put adsense with other ad company on my site at the sametime , example , buysellads.com's ad and yahoo ads . thanks
Even if you can, its not a good idea. Adsense pays most, so you get most from clicks from adsense ads.So its always best way to use only best paying company ads on your site.
Adsense is usually going to pay you the highest as far as this type of monetization. What you might want to consider is to use different ways to monetize your site along with Adsense. Options would include Amazon Associate, CPA offers, and maybe ClickBank products. This way you are offering choices and creating multiple income streams at the same time. Good Luck! Just my 2 cents... Ira
