I made a blog few months back,I wanted to add adsense for it but yesterday I found out that the e-mail address I use is blacklisted by google adsense,I have applied for google adsense some years back but they replied back that the site did not had much content.Why would they blacklist my email address?Can I have a new adsense account?
They usually don't allow adsense for what they deem to be "personal content". I've tried it before on a personal blog. Also (as you found out) they only allow ads once the site has a fair bit of content on it.
I can't find a link to it, but I suspect that's the reason.
Ok, I've read around a bit and it might be that it refers to the content between the targeting tags that you're supposed to put in your HTML. Maybe there's not enough content between the tags?
