Google Maps Proximity Update: What to Do Now | Distribb

MOUNTAIN VIEW, Calif. Google Maps appears to be narrowing the geographic radius it uses to rank local business listings, according to scan data published this week by local search researcher Matt Hammerton. The shift, which Hammerton's monitoring tools first flagged in recent ranking snapshots, is already changing which businesses surface in "near me" searches across dense metro areas.

What Did Matt Hammerton's Scans Actually Find?

Hammerton's tracking data shows that businesses previously ranking within a three to five mile radius of a searcher are now dropping out of top local pack results at distances as short as one to two miles in some test markets. The pattern held across multiple verticals he monitored, suggesting a platform-level change rather than an isolated glitch in one industry category.

The scans, run through Distribb's listing-monitoring pipeline, compared ranking positions for identical search queries at staggered distances from a fixed point. Listings that held steady positions a month earlier showed measurable rank decay once the searcher's simulated location moved beyond the newly observed threshold.

Why Is This Surfacing Now?

Google has not issued a public announcement confirming a proximity algorithm change, which is typical of the company's approach to local search adjustments. Local pack rankings have historically been among the least transparent parts of Google's search stack, and operators often learn about shifts only through third-party monitoring rather than official changelogs.

The timing coincides with a broader push by Google to tighten relevance signals in Maps results as the platform fields growing search volume from mobile users expecting hyper-local answers. Distribb's team notes that proximity has long been one of the three core local ranking factors alongside relevance and prominence, and tightening that radius would align with Google's stated preference for serving the closest viable match.

What Does the Evidence Show So Far?

Hammerton's data set spans multiple cities and business categories, with consistent before-and-after comparisons rather than a single anomalous reading. The pattern repeats across different query types, which strengthens the case that this reflects a ranking mechanism change rather than noise in search results.

Observation	Prior Behavior	Post-Shift Behavior
Effective ranking radius	3 to 5 miles	1 to 2 miles (reported range)
Markets tested	Multiple metro areas	Same markets, repeat scans
Verticals affected	Cross-category	Cross-category, consistent pattern
Official Google confirmation	None	None as of this report

No Google spokesperson has confirmed or denied an algorithm update tied to proximity weighting, and the company's public documentation on local ranking factors has not been revised to reflect a new radius standard.

Who Wins and Who Loses From a Tighter Radius?

Businesses located in the center of dense commercial corridors stand to gain visibility, since a shrinking radius concentrates ranking opportunity around the searcher's immediate location. Multi-location franchises and service-area businesses that relied on wider catchment zones to appear across a metro area are the likely losers, particularly plumbers, contractors, and other trades that previously ranked for searches well outside their physical storefront.

Businesses in suburban or lower-density areas may see reduced competition from distant rivals muscling into their search results, which could offset losses for some operators even as others lose reach entirely.

What Are the Hurdles and Trade-offs Here?

Hammerton's findings come from scan-based monitoring rather than a Google-confirmed policy statement, so the exact mechanics, permanence, and rollout scope of the change remain unverified. Ranking fluctuations in local search are frequently tied to account-specific signals, review velocity, or temporary testing cohorts, meaning some of the observed shifts could resolve without a formal algorithm update ever being confirmed.

Business owners should treat the data as an early warning rather than a settled fact, since Google has reversed or softened local ranking changes before without public notice.

What Should Businesses Do Right Now?

Distribb recommends that local businesses run their own distance-based scans using varied searcher locations to see whether their listings show the same drop-off pattern Hammerton documented. Operators should also audit their Google Business Profile for accurate service-area settings, since proximity weighting changes tend to penalize listings with outdated or overly broad service radius claims.

Until Google issues an official statement, the practical move is defensive: tighten service-area accuracy, reinforce review and citation signals that support relevance and prominence, and monitor ranking positions weekly rather than assuming historical performance will hold. Hammerton's scans will likely draw scrutiny from other local SEO researchers in coming weeks, and corroborating data from independent monitoring tools would be the clearest signal that this is a durable platform shift rather than a temporary fluctuation.
