Question - When to I start to monetize my site? I'm not in any rush, but I know some people have started after only a few
pages. I just wondered about your thoughts on when to apply to affiliate programs, and to Adsense etc.
Answer - Go ahead and apply to Adsense (but make sure you test everything first or they'll know your application back.)
You can apply for adsense
here, and I've put a few tips on the page as well before you do.
