my other sites are running fine, but the old ones with photo galleries (travel etc) are really paying peanuts : average CTR is 0.3%, average click (mostly hotels) pays 0.10/0.20 cents. is it normal ? better make "review" site with photos instead of just photos and few captions ? i mean, the users are there, the impressions are there, the issue is just the clicks pay nothing and the CTR keeps being very low (only rarely it hits 1%). any suggestion ?
