The Technical SEO Playbook
The plumbing your content is losing to.
The best content in the world cannot rank on a broken foundation. Only about 33% of sites pass Core Web Vitals, and pages that fail see roughly 18% lower visibility. This 2026 Edition playbook is the technical SEO discipline Hotseat brings to client sites: how to prioritise between crawl, render, and speed; crawlability and indexation; site architecture and internal linking; Core Web Vitals with a focus on INP; JavaScript and rendering for both search and AI crawlers; structured data; and the measurement framework that retires the Lighthouse score.
