The best way that I've found to maintain an average amount of views, is to publish on a consistent schedule. For instance, I know some publishers on HubPages who publish one Hub every two days at a specific time, and they've noticed a great consistency with their earnings/views. However, I must note that my highest ever amount of views actually occurred whilst I wasn't writing on HubPages at all!
For around two weeks my views were constantly at around 1,000 views daily, and I believe this was due to me having a break from publishing content. Maybe sometimes you need to take a short break from publishing hubs, so that they can naturally mature and gain ranks on the search engines. Especially, if you are publishing high quality/keyword optimised content.
