Google uses the registered address on a Business Profile as a primary proximity signal, and that signal decays as searcher distance increases. A firm with one office in downtown Houston will naturally surface for searches originating near that office but lose relevance as queries move toward a suburb fifteen miles out. This is not a flaw — it is how the algorithm weights physical presence. A firm that dominates auto accident searches in its home city may not appear at all for the same query typed from a neighboring city if no physical presence or strong proximity substitute exists there.
Google cross-references the city name in a firm's Business Profile against how that firm's name, address, and phone appear across the broader web — directories, legal listing sites, and local press. If a firm's citations consistently reference its home city but rarely or never mention the neighboring city, that imbalance signals a weaker geographic footprint in the second market. A personal injury firm that earned local press coverage and directory listings around a major slip-and-fall verdict in its home city built city-specific citation equity it has not replicated elsewhere. The result is uneven local authority across municipal boundaries.
Google parses the content of reviews, and reviewers frequently mention where an accident occurred or where they are located. A profile dense with reviews that reference one city name — "my car accident in Springfield," "helped me after my crash near downtown" — builds topical and geographic relevance for that city. When few or no reviews mention the neighboring city, that profile carries less weight in the second market's 3-Pack. For a PI firm, this means the geographic distribution of past clients, and whether those clients left reviews, directly shapes which municipalities the profile ranks in.
The Google Business Profile services section allows firms to list individual practice areas, and those entries contribute to relevance matching against specific queries. A firm that lists "auto accident attorney" as a service but does not pair it with any location context in its profile is competing on a generic signal that favors the closest physical address. Firms in the neighboring city that have built out their services section with more complete entries — including area-specific language where policy allows — absorb the relevance advantage for searches originating there. The services section is a structured signal Google reads before many other profile elements.
Local rankings are always relative — a firm is not measured against an absolute standard but against competing profiles Google considers for the same query in the same location. The neighboring city may have a law firm with a decade of reviews, a verified address, strong citation volume, and active Google Posts, all concentrated in that market. That competitor's relative strength in its home city means it sets a higher bar to displace. A personal injury firm that dominates one city has likely outcompeted weaker local profiles there; in the next city, it faces incumbents it has not yet matched on any of the core signals.
Google Posts are indexed content on a Business Profile and contribute to relevance signals for topical and local queries. A firm that consistently publishes posts about cases and legal topics relevant to its home city — mentioning local landmarks, local courts, or local accident patterns — reinforces geographic relevance for that city. When those same posts never reference the neighboring municipality's roads, courthouses, or case types, the profile accumulates no geographic signal for the second market. Posts about a trucking accident on a specific highway or a premises liability case at a local property anchor the profile to a place in a way that generic posts do not.
Google's local ranking algorithm incorporates the authority of the website linked to a Business Profile, and locally relevant inbound links are a component of that authority. A firm whose website has earned links from local news outlets, bar association event pages, and community organizations in its home city has built a locally-anchored web authority signal. That signal is geographically concentrated — links from the home city's local press do not automatically extend authority into the neighboring city's search results. A firm that has not earned any links from publications, directories, or organizations based in the neighboring municipality starts that market with a structural web authority deficit.
