How Browsers Really Parse HTML (and What That Means for SEO)

Musonera Jean Claude's podcast · Feb 26, 2026 · 32m

Martin and Gary unpack how HTML parsing really works, why the HTML standard is so lenient, and how messy markup can silently break key SEO signals like hreflang and rel=canonical. They revisit validators and cross‑browser hacks from the Netscape/IE days, and discuss whether semantic HTML and strict validity truly matter for search.
