Here are Dallas-area agencies known for working with law firms and offering technical SEO services (speed, crawl/indexing, schema, site architecture, mobile/responsive fixes, Core Web Vitals, etc.). I list firms that explicitly market legal/attorney SEO and mention technical SEO or related technical services on their pages:

• Everest Legal Marketing — legal-focused agency that lists Dallas services and law‑firm SEO (site audits, on‑page & technical work). (everestlegalmarketing.com)

• 9Sail — explicitly describes law‑firm SEO for Dallas and calls out technical SEO (performance, security, mobile). (9Sail.com)

Notes and next steps

• I pulled these from each firm’s Dallas/legal‑SEO pages; if you want a shortlist of 2–3 to contact, tell me whether you prefer: (A) price-minded/smaller shop, (B) legal-specialist boutique, or (C) larger agency with full-service capabilities — I’ll rank by that and add contact pages and quick vetting questions to ask each one.
