I have built a new site(finished last week, but no SEO, no clients). I know apply for ads need a long time. So I send my request to google adsense, and then send my site to web search and do the SEO, but yesterday I received an e-mail: Thank you for your interest in Google AdSense. Unfortunately, after reviewing your application, we're unable to accept you into Google AdSense at this time. what is the preparation before apply for ads? Am I ignore something must do before apply for ads? (what should I do before? then apply to Google AdSense?) And how to apply Google doubleclicks? Or other ads service? I am newer in this section. can anyone recommend me some good ads proverder? Thanks.
Your site should have content and comply with adsense's rules and be about something adsense wants in their publisher network.
