I have 2 sites, combined they get around 100-160 visits per day each of these sites have ads on almost every single page.
Yet, on average I only make around £1-1.50 per month... is this normal? Or is there something wrong? Am I placing them ineffectively?
If it makes any difference, I use the same HTML code for almost all of my ads... because for some reason any new code doesn't seem to show up even after weeks, could this be the problem?
