I realize no one has a perfect crystal ball and Google is chaning the game moment by moment. Yet, I was wondering what your thoughts are and your experience on your Hubs, do they grow over time with traffic or simply plateau?
I read WryLilt's post about Hubs not maturing until 6-9 months.
It also depends on how much competition there is out there for the topic you're writing on, as well as how much new content is introduced. Google, in the past, has tended to favor older content over new, except for when it's initially posted on the web.
I think it was Paul Edmondson who posted and said that admin has calculated that it takes Hubs three years on average to mature, which he described as reaching their peak potential of traffic/audience reach.
My own experience is much more in line with that time estimation than WryLilt's quoted time frame.
And as for evergreen Hubs, I have some that are 4-5 years old which is about as old as a Hub can be and they are steadily productive.
