I'm just curious. Its mostly based on traffic, bounce rate, and visitors right? I've read that blogs normally have a higher bounce rate than normal websites so how would the prices differ for blogs? And, let's say a "big" company/corporation website (e.g: amazon, funimation, tokyopop, sony music, etc etc etc) wants to buy an ad space on your blog. How much should you charge them? Would the price be higher since they're "big corporations" or would it be based normally as if they were regular small sites/individuals? And what sort of payment do you recommend doing for these big guys? Does paypal still seem professional enough? Do these companies even have paypal? I think amazon might but the others I don't know...
