Hi, not sure if this is the right place to post. I've started blogging in November (it's a product reviews blog) and last night I was delighted that I could apply for Ad Sense. After submitting my application, straight away ads automatically appeared on my blog, but after an hour where the ads were are now just a blank space. Has my application been approved because I can sign in the Ad Sense account or am I still waiting for approval? I'm completely new to blogging and have no ideas at all.
