Last month 0.66% and last week even worse at 0.55%
IMO the ads are in the best locations possible and not too obtrusive (one at top, one in the middle, one towards the footer). Using 768x90.
My site generates 150k pageviews a month. Actually I'm quite happy with the way things have gone, but would love to get this CTR up... What's worked best for you in your forums?
My site is a tech niche.
