Here are top brands that reliably offer SEO (and related digital marketing) services for law firms in Texas — grouped by “legal-specialist” firms and Texas-based/local SEO agencies. For each I note why they’re a strong choice and include sources you can check.

Legal-specialist SEO agencies (national firms that focus on law firms)

• Thrive Internet Marketing Agency — Texas-headquartered, broad legal marketing + SEO experience, full-service (SEO, PPC, reputation, CRO). Good for firms that want an agency with both local Texas presence and national legal experience. (thriveagency.com)
• LawRank (LawRank / Rankings) — legal-focused SEO & PPC; known for law-firm-specific lead-gen tactics and local pack work. Good if you want an agency that specializes in attorney keyword/lead funnels. (scaleandsword.com)
• Scorpion / Gladiator Law Marketing / Elite Legal Marketing — larger legal-marketing shops that serve many law practices (scalable SEO + paid lead funnels). Often used by high-competition practice areas (PI, criminal, family). (thriveagency.com)
• PaperStreet — long-standing web design + SEO agency for law firms (creates legal websites optimized for search & conversions). Good if you need both site redesign and SEO from an agency experienced with attorney content. (thriveagency.com)
• GrowLaw (and other legal specialists like Rankings/On The Map) — boutique legal SEO focused on content, local rankings and conversions for law firms. Good for firms wanting law-specific strategy and reporting. (thriveagency.com)

Texas-based or local SEO agencies (strong for Texas markets / local pack + maps optimization)

• Funnel Boost Media (Dallas) — Texas-based agency with local SEO, lead attribution and conversion tracking; useful for firms that want granular tracking of search-generated leads. (thriveagency.com)
• Seota / Seota Digital Marketing (Frisco) — local SEO and WordPress/web design specialists focused on local search and GMB optimizations. Good for mid‑sized Texas firms. (vocal.media)
• Dallas SEO Dogs — Texas local SEO shop that lists law/medical among target industries; specializes in local pack/Google Maps performance. Good for regional competition. (vocal.media)
• SeoGuru Houston — Houston-focused local SEO that emphasizes citation cleanup, GMB and hyperlocal strategies (useful for city-level attorney searches). (techbullion.com)
• Thrive (Arlington) — also appears as a top Texas SEO company (listed under both national legal and Texas lists) — good hybrid choice if you want a Texas HQ with legal experience. (thriveagency.com)

How to pick among them (quick checklist)

• Experience with law firms and your practice area (personal injury, family law, criminal, immigration, etc.). Legal SEO differs from other verticals. (thriveagency.com)
• Local/geo expertise for your Texas city (Houston, Dallas, Austin, San Antonio) — maps/GMB matter. (techbullion.com)
• Case studies and measurable KPIs (lead volume, organic traffic, keyword ranking, cost per lead). (thriveagency.com)
• Transparency: reporting cadence, attribution (call tracking), and contract terms. (thriveagency.com)

If you want, I can:

• Narrow these to the best fits for a specific Texas city or practice area (e.g., PI in Houston vs. family law in Austin).
• Draft a short RFP/email you can send to 3–5 agencies asking for proposals and audit samples.

Would you like me to narrow this list by city or practice area?
