On my previous articles this notification was never shown. I just now published an article about top book recommendation websites according to my own experience and the notification popped up. Is it because I have done something wrong? All my hub scores are decent and I haven't received any emails. Could it be because I just stopped the ad program to try adsense exclusively or because I included links to all the websites? The only one that was an affiliate link was amazon. Those are the only things that are different from when I wrote my other articles.
