Here's an insight to dig for: How many of your buyers are return visitors who had their interest piqued in an earlier visit, vs. first-time visitors? Figuring that out might yield some useful insights.
Since you have the visitor's attention at the beginning, with your articles, you may try to capture their email at this stage via newsletter, coupons, contests, etc.
Keep their eyeballs on your brand so when they are ready to buy they may be more readily to remember you.
Another idea: Do you have "related posts" listings at the end of your articles to encourage clicking to other parts of your site.
