Great content has no shelf life
A great example of evergreen content from over 50 years ago
Earlier today I was reading a great post on creativity, it was thought provoking, relevant and it was written 55 years ago by Isaac Asimov.
You will be surprised to know that Asimov didn't write this thinking it would make a great blog post some day, sit on the first page of some major link sharing websites and get hundreds or thousands of shares across various social networks.
He didn't even write it to a mass audience, he wrote it for a small team of scientists.
This is clearly an extreme example, there are few that could get their point across just like Asimov but the point I would like to make is that if you invest in good content it can reap rewards for years to come.
Can you say the same about your marketing or SEO campaign? You cannot. I have made the case against evergreen content before, but there are clearly some benefits.
