How to Build a Schema Markup Deprecation Strategy When Google Phases Out 18 Structured Data Types for AI-Native Entity Extraction in 2026

Google's announcement in late 2025 that they'll phase out 18 structured data types by Q3 2026 sent shockwaves through the SEO community. With AI search engines now processing over 40% of all queries and entity extraction becoming increasingly sophisticated, this shift represents the biggest change to structured data since schema.org launched in 2011.

If your content strategy relies on the deprecated schema types, you need to act fast. Here's your complete guide to building a deprecation strategy that not only protects your current visibility but positions you for the AI-first search landscape.

Understanding Google's Schema Deprecation: What's Changing and Why

Google's decision stems from their AI systems becoming advanced enough to extract entities and relationships directly from content without explicit markup. The 18 deprecated types include several commonly used schemas:

  • LocalBusiness (being merged into Organization)

  • SoftwareApplication (replaced by AI-native app detection)

  • VideoObject (superseded by multimodal AI analysis)

  • Recipe (integrated into broader CreativeWork)

  • Event (enhanced through natural language processing)

  • JobPosting (replaced by AI job extraction)

    • This shift affects an estimated 2.8 million websites globally, with e-commerce and local businesses facing the highest impact. The transition period runs through September 2026, giving you roughly 8 months to adapt.

    Why This Matters for AI Visibility

    AI search engines like ChatGPT, Perplexity, and Claude increasingly rely on semantic understanding rather than structured markup. They're looking for:

  • Natural entity relationships in your content

  • Contextual relevance over rigid structure

  • Conversational information architecture that answers user questions

    • This evolution means your content needs to be both human-readable and AI-interpretable without relying on schema crutches.

    Step 1: Audit Your Current Schema Implementation

    Before building your deprecation strategy, you need a comprehensive audit of your existing structured data.

    Inventory Your Schema Types

    Start by cataloging every schema type across your site:

  • Use Google Search Console to identify all structured data types Google recognizes

  • Run a technical SEO crawl with tools like Screaming Frog or Sitebulb

  • Document which pages use deprecated schemas and their current performance

  • Identify high-value pages that depend on deprecated markup for visibility

    • Assess Performance Impact

    For each deprecated schema type, analyze:

  • Current click-through rates from rich results

  • Search visibility for target keywords

  • AI search engine citation frequency

  • Conversion rates from organic traffic

    • This data will help you prioritize which migrations need immediate attention versus those that can wait.

    Step 2: Map Migration Paths for Deprecated Schemas

    Not all deprecated schemas disappear entirely – many are being consolidated or replaced.

    Direct Replacements

    LocalBusiness → Organization

  • Migrate properties like address, telephone, and openingHours

  • Add @type: "Organization" with additionalType for business category

  • Include sameAs properties for social profiles

    • SoftwareApplication → Product

  • Convert app-specific properties to general product attributes

  • Focus on offers, review, and aggregateRating

  • Enhance with natural language descriptions of functionality

    • AI-Native Alternatives

    For schemas being fully deprecated, shift to AI-optimized content strategies:

    VideoObject → Enhanced Content Structure

  • Use descriptive headings that include video topics

  • Add detailed transcripts and summaries

  • Structure content with clear Q&A sections

    • Recipe → Conversational Format

  • Write recipes as step-by-step narratives

  • Include ingredient substitutions and cooking tips

  • Answer common questions within the content

    • Step 3: Optimize Content for AI-Native Entity Extraction

    With structured markup becoming less critical, your content itself must carry the semantic load.

    Enhance Entity Recognition

    Use Clear Entity References

  • Name entities explicitly: "Apple Inc." instead of just "Apple"

  • Provide context for ambiguous terms

  • Include relevant synonyms and variations

    • Build Semantic Relationships

  • Connect related concepts within paragraphs

  • Use transitional phrases that show relationships

  • Create content hierarchies that mirror real-world connections

    • Structure for Conversational AI

    AI search engines excel at answering specific questions. Structure your content to match:

  • Lead with direct answers to common questions

  • Use question-based headings that match search intent

  • Provide context and examples for complex topics

  • Include relevant statistics and data points

    • Tools like Citescope Ai can analyze your content's AI interpretability and suggest optimizations that improve entity extraction without relying on deprecated schemas.

    Step 4: Implement Remaining Structured Data Strategically

    While 18 types are being deprecated, core schema types remain valuable:
