Quick guidance to pick the right vendor

• Ask for a technical SEO audit sample (crawl report, site‑speed score, schema/structured data review, indexability issues, canonicalization, mobile UX). Prefer audits that reference measurable tests (Lighthouse, PageSpeed, Screaming Frog, Search Console logs).
• Confirm law‑industry experience (E‑E‑A‑T, attorney bios, malpractice/ethical ad rules) and examples of Dallas clients or results.
• Get deliverables & reporting cadence (what they fix vs. what they recommend, timeline, and KPIs).
• Ask about in‑house vs. outsourced work, pricing model (project vs. retainer), and conflicts of interest (don’t work with direct competitors if that’s important).

If you want, I can:

• narrow these to agencies with offices physically in Dallas,
• pull sample technical audit excerpts or client case studies for any 2–3 of these, or
• draft an RFP/email template you can send to them asking for a technical SEO proposal. Which would you like?
