Hi, One one of my sites, the ads don't show on the homepage (google public ads appear), although it's got enough content and it's properly optimized. On all other pages ads display without any problems. What do you think could be the problem?
I think you mean that adsense public ads appear at your homepage, not adsense ads not shown. Try change your ads placement, it works
Did you implement section targeting? If you have content in your web page, you won't see community ads for long.
