On my site, there are pages that I know adsense does ok on with CTR of 2ish%. Other ages I know do bad with CTR of 0.5ish% Just wanted to know if there is any adverse effect of me having ads on pages with such low CTR (0.5%) - should I remove these ads or leave them be?
you might get smartpriced if those ads are non-converting..smart pricing will affect your entire account
