I just received my confirmation a few hours ago from Adsense. I pasted the code into my wordpress blog (via MightyAdsense) but no ads have appeared on my new posts. How long until the ads start showing (I understand I'll probably be seeing PSA for a little bit)?
You should have adsense show up immediately. It may be irrelevent at first, but it takes a few minutes for it to post relevent ad. You may want to check your placement if you don't see any changes at all.
I'm an idiot. LOL I just realized my work has an adblock-type program in place on the network. Thanks anyways
