After delivering web articles for last 6 months we have decided to promote our Article Writing service. Would it be a good idea to publish the full articles on our portfolio pages? Or just 3/4 lines , then a buy this article? What works better in terms of conversion?
I would offer a few (Four or five, depending on how many you have.) full Articles and then the rest just four to six lines. Offering full articles will cause you problems, such as people stealing them.
