technical-seo-2026-delta
description
Use when a site needs only the 2025–2026 Google/Bing technical changes checked (generative eligibility, snippet controls, dead rich results, crawler split, new Search Console reports and measurement caveats, EEA site-reputation split, regional SERP units, emergency crawl-rate controls). Not a classic full-site technical audit.
- What it does
- Checks only what changed in 2025–2026 (generative eligibility, snippet controls, crawler split, dead rich results, new Search Console reports) and returns a pass/fail list with evidence URLs.
- Where it stops
- Not a classic full-site technical audit.
One-time payment. The zip has all 11 skill folders with their references.

- # Technical SEO 2026 delta
- Apply the official 2025–2026 deltas, then stop. Do **not** redo classic Core Web Vitals, title/H1, full hreflang programs, sitemap hygiene, or generic JSON-LD recipes here. Those are out of scope for this skill.
- **Host-hygiene guard.** Before ranking a www/apex (non-canonical host) cleanup as a traffic lever, check Search Console impressions on the non-canonical host. Near zero means a hygiene ticket, not a growth lever.
- **Freshness.** The checklist facts are dated (current as of early November 2026). If they are more than 14 days old, run the `search-change-triage` skill first and update the checklist with anything material.
- **Checklist (load when scoring):** [references/checklist.md](references/checklist.md): generative eligibility, snippet/preview controls, crawler matrix, rich-result overrides, indexation/JS/AMP/Discover/Preferred Sources, EEA site-reputation split, regional SERP aggregator/supplier units (+ UGC Fresh Data Program scope note), Bing freshness, emergency crawl-rate reduction (`Retry-After`).
