Hot photoshop tutorials I tried to blend it, I made my best.. but anyway, I would like to hear some experts opnions *there's a different ad placement in tutorial page.. have a look.
Interior pages top horizontal ad, your black background choice with grey text is hard to read. Consider a lighter color type for the link description.
I think you should focus on getting traffic first. Your placement won't matter if you have no traffic.
Link ads between posts is good, just make sure you don't exceed the per page limit on ad blocks, which can REALLY get out of hand if you are using a loop to display DB rows. I think the limit for ad blocks is 3 per page? Site looks nice, now focus on content content content. You can have the best ad placement in the world but with no traffic you have no earnings.
