I get that to apply for an AdSense account, a website needs to already have "sufficient content". As you can guess my website, being brand-new, did not. I am not disputing that fact, so I do not think this is a duplicate with other questions that do.
I do however wonder why this is a policy?
I guess their reasoning MIGHT be because Google wants to uphold a sense of quality in the content they support. A practically blank website is not quality content (yet).
But isn't this a Catch 22? Creating quality content takes time (and thus money). Without ad-revenue to back this up, it's not easy to justify the expense (to my wife mostly, but that is beside my point :) )?
Compare with YouTube where you can apply for a partner account having uploaded 0 videos.
Another reason might be that they won't know what ads to show on an "empty website", but seems to me they could just as well pick something "random, but safe" themselves...
If anyone has an authoritative answer (based on information from Google or personal experience) I'd be happy to hear it.
