Structured data becomes a retrieval qualifier in 2026. 67+ AI bots now crawl the web. Here is the complete technical checklist for WordPress sites.
Yoast's 2026 predictions team made a clear call: "Structured data shifts from ranking enhancer to retrieval qualifier." The implication is that schema markup will transition from a competitive advantage to a baseline requirement — sites without it simply will not show up in AI-mediated search results.
| Schema Type | Required For | Key Fields |
|---|---|---|
| Article / BlogPosting | Blog posts, news, editorial | headline, datePublished, dateModified, author, publisher |
| Product + Offer + AggregateRating | E-commerce product pages | name, sku, brand, gtin, mpn, offers.price, aggregateRating |
| FAQPage | FAQ sections (rich results + AI citations) | mainEntity[Question.name, Answer.text] |
| BreadcrumbList | Navigation context for AI | itemListElement[position, name, item] |
| Organization / LocalBusiness | Brand identity, local SEO | name, url, logo, sameAs, address, openingHours |
2026 standard: Every page should have at least one schema type. Product pages need Product + Offer + AggregateRating. Blog posts need Article with author entity. Homepage needs Organization.
| Bot | Platform | Respects robots.txt? | Reads schema? |
|---|---|---|---|
| OAI-SearchBot | OpenAI (ChatGPT Search) | ✅ | ✅ |
| GPTBot | OpenAI (training) | ✅ | Partial |
| ClaudeBot | Anthropic | ✅ | ✅ |
| PerplexityBot | Perplexity | ✅ | ✅ |
| Google-Extended | Google (AI training opt-out) | ✅ | N/A |
| Bytespider | ByteDance (AI training) | ❌ (widely reported) | Unknown |
LCP < 2.5s (optimize hero images: WebP, srcset, CDN), INP < 200ms (minimize main-thread JS, defer non-critical scripts), CLS < 0.1 (set explicit width/height on images). MakeWPFast vendor-published benchmark of Shop2LLM: TTFB +5ms, negligible memory overhead (under 1 MB), zero additional database queries — if a plugin adds performance overhead, its features need to justify it.

| Sitemap Type | Priority |
|---|---|
| Standard XML (posts, pages) | Must have |
| Image sitemap | Must have (e-commerce) |
| Video sitemap | Nice to have (media sites) |
| News sitemap | Must have (news sites) |
| Paginated (1000+ URLs) | Must have (large sites) |
Google Search Console integration closes the loop — without it, you are generating sitemaps without knowing whether Google is actually indexing them.
AI systems evaluate content quality partly through link structure. Every page should have at least 3 internal inbound links. Product pages should be linked from category pages and comparison content. Blog posts should be interlinked using relevant anchor text — not "click here." Orphan pages (zero internal links) should be identified and linked.
