The 'Çheck Traffic' tab which is there with every article, does give you a inkling of the traffic, your article is generating. But it doesn't give much details about the traffic and is not very user friendly. I for one, prefer to use the StatCounter tool, which is very much user friendly and gives even the minute details of the traffic, like place of origin, time, keyword, platform used, search engine, etc. The details are given on a day to day basis or whichever way you like. Every article or ask expert question raised by you, if they are generating traffic, are all listed one by one. It gives you a very clear picture of the resources that are being visited. You even get the country profile of the visitors.
Whether ask expert answers and forum responses can be tracked or not, I am not very sure. But the ask expert questions are getting tracked and probably the forum threads too will get tracked if they are generating traffic.
There are other ways to track your traffic, StatCounter is one of them. It's a very helpful tool. Through this tool only, I realized that one of my old article was getting good page views and I got it republished. Do register now, in case you haven't done yet. In the dashboard itself there's a tab to configure the StatCounter. There are however, some limitations with StatCounter. The earnings cannot be monitored, perhaps. For monitoring the earnings (even though meagre), I use the AdSense site. In the AdSense site individual articles can be monitored for the revenue they are generating.
Patience and perseverance pays
