772 Unpacking LLMs.txt with Carolyn Shelby

Erin welcomes Carolyn Shelby, the Principal SEO at Yoast and a renowned authority in technical and enterprise SEO. Carolyn brings decades of hands-on experience from her pioneering days in digital marketing, working with brands like Disney's ESPN, Tribune Publishing, and major nonprofits. The conversation kicks off with a surprising twist—Carolyn's unique title as Queen of the micronation Ladonia—before diving into her role at Yoast and their latest innovation: the LLMs.txt file generator. Carolyn explains how this new file helps websites communicate their most valuable content directly to large language models like ChatGPT and Google's AI, streamlining the way future search agents discover and answer questions with information from your site. We explore what inspired Yoast's push to roll out LLMs.txt to over 13 million sites, what website owners should include in their files, potential industry pushback, the adoption challenge with search giants, and how this moment could change the way websites optimize for AI-driven search results.
