Robots.txt + indexing accuracy: Flowchart no longer claims robots-blocked pages "Cannot Index" (Google may still index them). Added nuance that noindex cannot be seen when robots.txt blocks crawling. Clarified mutual exclusivity of robots blocking vs noindex.
noindex, follow link-equity claims: Replaced definitive "passes/preserves link equity" language with Google's stated uncertainty — persistently noindexed pages may not pass equity.
GA4/GSC inaccuracies: Removed incorrect "GSC conversion tracking" claim. Corrected GSC-GA4 integration description (search data, not conversion data). Replaced deprecated attribution models (First-click, Linear, Time decay, Position-based) with current models (Data-driven, Paid & organic last click, Google paid channels last click).
Structured data corrections: Removed identifier_exists from Product schema (it is a Merchant Center feed attribute, not schema markup). Corrected Organization schema required/recommended property labels. Moved Product image to required properties. Fixed offers/availability/price requirement sources.
FAQ, HowTo, Sitelinks Search Box: Updated for full deprecation — FAQ rich results deprecated May 2026, HowTo removed, Sitelinks Search Box removed November 2024.
E-commerce faceted navigation: Replaced copy-pasted funnel-stage content table with correct faceted nav control strategies.
