If there's one person qualified to talk about social media marketing, it's Steven Bartlett. He built Social Chain — a social media marketing agency that worked with brands like Apple, Coca-Cola, and Amazon — before selling it for tens of millions. He grew The Diary of a CEO to over 10 million YouTube subscribers using the very strategies his guests discuss on the show.
This guide covers the best Diary of a CEO episodes about social media, marketing, and content creation — with key takeaways from each so you can apply the lessons immediately.

Bartlett has hosted several guests who work inside social media platforms or study algorithms professionally. These episodes reveal how content is distributed, why some posts go viral while others die, and what creators should actually optimize for.
Key takeaways:
After watching dozens of marketing-related DOAC episodes, clear patterns emerge. These five principles come up again and again, regardless of the guest:
Every successful marketer on the show shares the same philosophy — lead with value. Give people something genuinely useful before asking for anything in return. Whether it's free content, a free tool, or free education, the transaction starts with generosity.
Bartlett himself is living proof. The reason DOAC grew so fast is that the conversations feel real. There's no script, no rehearsal, and guests are encouraged to be vulnerable. In an era of polished, corporate content, authenticity stands out because so few people are willing to do it.
Most creators spend 90% of their time making content and 10% distributing it. The guests on DOAC consistently argue the ratio should be reversed. A mediocre piece of content with great distribution beats a masterpiece that nobody sees.
Platform tactics change every month. Human psychology hasn't changed in thousands of years. The marketers who win long-term are the ones who understand why people click, share, and buy — not just which button to press on which platform.
An audience watches. A community participates. The most valuable brands on social media are the ones that make their followers feel like members. Bartlett's own community around DOAC — including the conversation cards, live events, and social engagement — exemplifies this principle.
Whether you're building a personal brand, growing a business account, or launching a content platform, here's a practical framework drawn from the best marketing episodes on DOAC:
