Just wonder anyone here has the same experiences with me where some of the pages in the webpage was without any Adsense Ads? When you refresh them a few times, the ads was displayed again. Please help me if you know what is the reason behind this. Thanks
sometimes, when there are no ads to be shown, google public service ads are viewed instead and when you don't accept that option, then it must show a 404 error page instead on an ad.
