I have been working on my blog and just had someone ask to run banners on it. I am new to blogging (about 3 months), and was just writing and learning SEO, but I would like to take advantage of this, especially since they have offered to help monetize my site even more than it is now. What fees are common for 160x600, 240x400, 300x250, 336x280, 468x60, 728x90. banners? They asked to have it on every page, and I am up to 629 pages as of 1/26/12. I do PR5 and up backlinks most of the time, and continue to build the site and increase visitors. Any suggestions? Thanks guys!!
