## Excluded sources (with rationale)

- **Neil Patel** — General-SEO popularizer. Local content broad-stroke; not operator-grade.
- **Brian Dean** — General-SEO. No focused local practitioner depth.
- **Matt Diggity** — Affiliate SEO focus, not local.
- **Aleyda Solís** — International SEO focus. Excellent practitioner, but local is not her vertical.
- **Caleb Ulku** — Dominant in YouTube organic results but content has popularizer / course-seller pattern. Did not earn anchor practitioner slot.
- **Generic "Top SEO Experts 2026" lists** — Methodology weights raw follower count, biases toward general-SEO popularizers over local specialists. Used only as cross-reference.

## Authoritative non-practitioner sources (used for verification)

- **Google Business Profile Help** — official guidelines for eligibility, suspensions, policies
- **Google Search Central** — algorithm update calendar, local search documentation
- **Whitespark blog** — research articles confirming practitioner claims

- **Search Engine Land** — industry news; algorithm update reporting
- **Search Engine Roundtable (Barry Schwartz)** — real-time SEO news; algorithm sweep documentation
- **DOJ trial revelations (2023-2024)** — confirmed Google uses NavBoost-style behavioral signals
