The problem with an everything is free model to begin with is you set expectations at that level and attract people who don’t want to buy things. You need to go in with the mindset of what content will get me buyers now, not later, which means you make offers from day one based on very clear positioning from day one (or no one will buy). You still provide value for free of course, but it’s tied in with immediate offers so you can set a standard and begin seeing if you actually have a business that makes money.
Your content absolutely deserves to be updated on a regular basis. There’s always new information popping up, new data, new techniques, methods, products, or whatever else it is that you write about. Your audience wants to read about what’s new. Google wants to see you write about it too. Literally, the world wants you to keep your content up to date. If you don’t … goodbye your Google rankings.
