a brief look at your site showed me what seem to be very interesting titles; factual and useful. On the other hand, they mostly fall into a niche.
What are you doing to give them exposure? If you're waiting for HP to do it, you'll be waiting for a long time. Once hubpages members are exhausted, what then?
Go search for sites, blogs that are about an article you wrote and find a way of introducing your article. You need to find a batch of new readers. EG: Find a blog about iPhones, and chat a bit,then offer your article. No doubt many will be interested.
Those are the ways I know. Maybe other members will help you with some other ways.
Hope you get the rising figures soon Debra. Go Girl, Go.
