Content for acquisition, the reader’s relationship is to the topic, they have to be convinced the topic is relevant to their life goals but it’s valuable despite who the topic.
Content for retention, the readers relationship is to you as the writer and the topic is merely there as a MacGuffin to help illuminate some aspect of you that is unique.
Business Insider had this down to a science over a decade ago. They started a series called “So Expensive”, detailing why various things were expensive, the first 4 videos in the series were: Caviar, Saffron, Rolexes and Horseshoe Crab Blood. Statistically, some tens of millions of people have organically had the thought of why the first 3 were expensive but zero people have even wondered why horseshoe crab blood was expensive. The 4th video was a way to test, of all the people who were willing to click on the first three, how many were willing to follow along to the 4th because of a trust in BI? The next 4 in the series was Vanilla, Silk, Louboutins & Scorpion Venom.
Creating all content for acquisition is both too exhausting and also sub optimal for the reader because they want deeper stuff to follow as well. I suggest up to 1 in 3 acquisition articles if you can manage when starting out but then ramping down to no more than 1 in 10 fairly quickly or you burn out.
