Views go up and down like a fiddlers elbow. As people searching for things varies. My most views in one day, on one hub was 700. But this has lasted for several months. It has now slowed down to around 100 - 200 per day.
It spikes often as it gets shared quite a lot when people find it. Then it goes back up to the 500 - 700 mark. I do not market it excessively and prefer to get organic traffic.
It is on the Google chrome browser. It has had 25,000 + views in just over 2 months. Titled 'This site has insecure content' It has very little in terms of on-page SEO apart from the obvious, and is my most popular hub, currently.
200 views in one day is pretty darn good going. Congratulations.
It really is a numbers game and the more good quality hubs you have, the more aggregate views you will get. It is not really about individual hubs but about a bunch of good hubs with great content.
There are hubbers on here with just a few more hubs than me, making a good second income. They have been on hubpages for years and their hubs are mature. Apart from the panda updates. etc.
I expect my earnings will catch up with them in the not to distant future.
