How Browsers Really Parse HTML (and What That Means for SEO)  @GoogleSearchCentral
Uploaded February 2026 | Updated September 2026, 2 weeks ago
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. You’ll also hear when link hints like preload, prefetch, and DNS prefetch help performance (and indirectly SEO), and where meta and link tags really belong.
