If you’re in the early stages of learning how to write for the purposes of content marketing then there’s value in writing every day. But that’s more to learn about what resonates with your audience, how to organize your thoughts in words, how to write a compelling title, etc. than it is good content strategy.
Does that make sense?
People have a lot of anxiety about publishing their thoughts so there’s a lot of value in saying, “Just write and click publish!” It’s just a matter of where you are as a company. If you’re trying to figure out how to get started, by all means, jump in and just get words out of your brain. But it’s not a long-term strategy.
