Brian Dean is the founder of Backlinko and Exploding Topics, both acquired by Semrush, which itself was recently acquired by Adobe for $1.9 billion. Brian's story starts exactly where a lot of great stories start: broke, directionless, and eating canned beef stew in his dad's basement during the 2008 financial crisis. He picked up a copy of The 4-Hour Workweek and took action. As is nearly always the case, his path wasn’t a straight line, but a series of winding turns, all fed by experiments. His journey includes failures, two successful exits, and a hard-won answer to the question most people never think to ask: what do you actually do with your freedom once you have it?This episode is brought to you by:Incogni, which automatically removes your personal data from the web, helping shield you from fraud, scams, and identity theft: https://incogni.com/Tim (use code TIM at checkout and get 60% off an annual plan)Fin powerful AI Agent for all your customer service: Fin.Ai/TimTimestamps:[00:00:00] Start.[00:02:53] From PhD pipettes to Dad’s basement to Jerry Springer.[00:04:38] The 4-Hour Workweek finds its dream reader — marginal notes and all.[00:06:04] First product flops, free traffic beckons, and SEO.[00:07:40] The 200-domain AdSense empire.[00:09:40] Dreamlining: From “escape the basement” to “3k a month in Thailand.”[00:11:27] When Google’s Panda update slapped the internet (and Brian’s empire).[00:12:32] Scared straight: Black hat to white hat via a hostel in Spain.[00:17:55] Backlinko is born.[00:19:50] The 200 ranking factors post: 25 hours of patent-digging, a million visitors.[00:22:13] New rule: One post a month, 10x better than anything out there.[00:23:02] Semrush comes knocking to buy his company — Brian ignores the email.[00:24:02] Taking celebratory shots at Legal Sea Foods while wondering where the contract is.[00:25:32] Due diligence hell: Hunting down ghosted freelancers and the contractor commandments.[00:29:25] SEC market-close rules vs. Brian’s 10 p.m. bedtime.[00:30:16] Post-acquisition: Hopping from one treadmill to the next.[00:34:19] Backlinko on autopilot, boredom on full blast, and the chapter everyone skips.[00:35:42] Exploding Topics: The paid newsletter mistake vs. the obvious SaaS play.[00:38:41] Data-driven content and the ChatGPT user stats flywheel.[00:41:00] Noah Kagan’s advice: Double down on what works — then 10x down.[00:42:26] Ready, Fire, Aim — the litmus test for would-be founders.[00:44:06] Startup costs: $500 for Backlinko vs. $90k to acquire Exploding Topics.[00:47:29] How love and a Craigslist apartment scam in Berlin landed Brian in Portugal.[00:48:48] Geoarbitrage still works — just don’t trust the 2007 pricing.[00:50:20] Post-exit stress: Oura Ring at 2x baseline and the Algarve hard reset.[00:52:21] Why founders who launch within a year of selling usually regret it.[00:53:30] Tennis as the ultimate void-filler: Fun, fitness, community, and fresh air in one sport.[00:54:31] The paradox of choice after exit: Structure, identity, and vertigo.[00:56:52] Parting thoughts.*For show notes and past guests on The Tim Ferriss Show, please visit tim.blog/podcast.For deals from sponsors of The Tim Ferriss Show, please visit tim.blog/podcast-sponsorsSign up for Tim’s email newsletter (5-Bullet Friday) at tim.blog/friday.For transcripts of episodes, go to tim.blog/transcripts.Discover Tim’s books: tim.blog/books.Follow Tim:Twitter: twitter.com/tferriss Instagram: instagram.com/timferrissYouTube: youtube.com/timferrissFacebook: facebook.com/timferriss LinkedIn: linkedin.com/in/timferrissSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
