Thank you for your question - I'm sorry that I just saw it today. It definitely took me a lot of time to get to this point (it will be 5 years on HubPages for me this October). I spent a lot of time writing Hubs, commenting on other Hubs, visiting the forums, etc. You earn higher scores when you take part in a variety of activities on HubPages, not just writing Hubs. And the more you do, the more hits you'll get.
