The guide also covers performance optimizations (zero JS by default, image optimization, CDN caching, No-Vary-Search headers), redirects, fuzzy 404 handling, and analytics setup. Written by Joost de Valk (creator of Yoast SEO), it reflects how SEO has evolved from keyword matching to serving both human readers and AI agents that parse meaning and walk knowledge graphs. ## Full article daily.dev links to this article rather than hosting it.
