Hey my youtube blog is averageing about 30,000+ unuiqe page views a month...can you take a look at my placement and tell me how i can improve?
30,000/mo, eh? http://www.sitemeter.com/?a=stats&s=s26dahamu Anyway, to answer your question... I'd switch it up in 2 week intervals. For the next 14 days, try putting just three of the 336 x 280 between your blog posts. Try adding a verticle 160x90 or something... just switch it up to find the right conversation. I've read that repeat viewers sometimes become blind to the ads, so a little change probably wouldn't hurt if people are coming back to your site.
on the right hand column get rid of the feedburner signup section -- move your google bnner up and contrast the color with the black -- i missed it 3 times looking at your site -- make it stand out a bit more....on your single post pages put a big squre abover the post itself - under the title but b4 the content -- make people see your ads
