I have subscribed to and been allowed to carry Word Ads on my blog. Yet, while I can see my Word Ads on my site, others cannot. Why is this? I asked a friend using Google Chrome to look and they didn’t appear. Likewise with Safari (they were both looking on iPad). I use Firefox. Is this anything to do with it? Or is there another reason (iPad)? I presume everyone should see them, am I wrong? Please help.
