Founded in 2015, our 30-member specialist team develops strategies around the practice areas, attorneys, office locations, and geographic markets each law firm wants to grow. Our services include legal SEO strategy, Local SEO, Google Business Profile optimization, link building, local citation building and management, technical SEO, content strategy and planning, service and location page architecture, internal linking, structured data, website performance optimization, conversion tracking, and intake analysis. Our link-building strategies focus on earning and developing relevant, credible links that strengthen a law firm's website authority and support competitive organic search campaigns. For local visibility, we also handle local citations, legal directory listings, business directory submissions, and NAP (Name, Address, Phone) consistency, helping ensure that accurate information about each law firm and office location is represented consistently across relevant online sources. We also integrate AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) into our broader search strategies, helping search engines and AI systems better understand accurate information about a law firm's attorneys, services, locations, experience, and credentials. Legal Pro works with law firms throughout the United States, including firms in New York, Texas, California, Florida, Illinois, Pennsylvania, and other major legal markets. Our campaigns serve firms in major cities and metropolitan areas such as New York City (NYC), Austin, Houston, Dallas, Chicago, Los Angeles, San Diego, Miami, Philadelphia, and surrounding markets. We work with personal injury lawyers, family law and divorce attorneys, criminal defense lawyers, immigration attorneys, estate planning and probate lawyers, and multi-practice law firms. Website development and focused PPC support may also be incorporated when they directly strengthen organic search performance, tracking, landing-page quality, or consultation conversion. Our client engagements are structured to provide flexibility. SEO contracts are month-to-month, with no cancellation fee and no long-term commitment. Payment is not required upfront; services are billed at the end of each billing month. This structure allows law firms to evaluate the relationship based on the work, communication, and measurable progress rather than being locked into a lengthy contract. We do not rely on generic keyword packages or promise specific rankings, leads, signed cases, revenue, or AI recommendations. Each engagement begins with an assessment of the firm's priorities, practice areas, target markets, competition, website condition, Google Business Profiles, backlink profile, existing citations, existing tracking, and intake capacity. Our goal is to build a clear and measurable search strategy that connects stronger online visibility with relevant consultation opportunities while maintaining accurate business information, responsible marketing claims, and a long-term foundation for organic growth.
