Am I dumb or am I dumb?????

 I've suddenly realised that for the last six months I didn't even understand what article marketing is let alone how you do it. 

I thought article marketing meant writing articles about all sorts of things and trying to earn money from them, as on Helium and HubPages, for example, i.e. marketing articles.

Now the light bulb's come on and I finally realise that it means using articles to market one or a few specific products that I have selected. 

No wonder that whatever I read about it in the past didn't make much sense!
