What the study was designed to answer.
The central question was: how many Google reviews does a local service business actually need to appear in the Google Maps local pack (the top 3 results shown in map-based searches) in a given market?
Anecdotal answers to this question vary widely and tend to be stated as universal thresholds without geographic or vertical context. A roofing contractor in Los Angeles competes in a materially different review environment than one in Boise, Idaho. The goal was to produce thresholds that are segmented by market size and trade category, not stated as single national figures.
The full benchmark findings are published at Google Review Benchmarks for Local Service Businesses (2026).
20 US cities across three market-size tiers.
Cities were selected to represent three distinct market-size tiers: major metros (1M+ population), mid-size markets (200K–1M), and smaller markets (under 200K). Selection within each tier prioritized geographic distribution across US regions.
7 categories, selected for search intent clarity.
Categories were selected based on two criteria: (1) the category must generate meaningful local pack search volume, meaning homeowners or commercial buyers regularly use Google Maps to find these businesses; and (2) the category must have enough competing businesses in most of the 20 cities to produce a meaningful top-3 sample.
How the data was gathered.
Search query structure
For each city and trade category combination, a standardized Google Maps search was performed using the query format: “[trade category] [city name]” — for example, “HVAC contractor Chicago” or “plumber Boise.” Searches were conducted from a consistent browser environment without logged-in accounts to reduce personalization effects.
What was recorded
For the top-3 (local pack) results and the next 7 businesses visible in the expanded map results, the following data points were recorded:
- Business name and map pack position (1, 2, or 3, or outside top 3)
- Total Google review count at time of snapshot
- Average star rating
- Number of reviews posted in the prior 90 days (review velocity)
- Whether the business had a claimed and complete Google Business Profile
Snapshot timing
All data was collected during Q1 2026 (January through March). Snapshots for a given city and category were taken within a single 48-hour window to minimize variability from ongoing review accumulation. The data reflects a point-in-time snapshot, not a longitudinal tracking study.
What “local pack” and “appears in results” mean technically.
Local pack
The “local pack” refers to the block of 3 business listings that Google displays at the top of search results for local queries, accompanied by a map. These are distinct from organic (blue link) results. Position 1 is the top listing in this block; position 3 is the bottom. Positions 4 and below are outside the local pack and require the user to click “More places” to see.
Minimum threshold for local pack appearance
A business “appears in the local pack” if it ranked in positions 1, 2, or 3 for the standardized search query in a given city. The minimum threshold cited in the benchmark data (47 reviews) represents the 25th percentile review count among all businesses that appeared in position 1, 2, or 3 across the full 20-city dataset for that category. It is not an absolute floor — it is the point below which most local pack appearances were not observed.
Review velocity
Review velocity is defined as the number of Google reviews posted in the 90 days prior to the snapshot date. This was estimated by counting reviews with visible dates within the 90-day window on the business's Google profile. Businesses with no reviews in the prior 90 days were recorded as zero velocity.

What this data does not tell you.
Point-in-time snapshot, not a longitudinal study
All data reflects a single Q1 2026 snapshot. Local pack rankings change over time as businesses accumulate or lose reviews, update their Google Business Profiles, or change service areas. The thresholds reflect the competitive environment at the time of data collection.
Proximity is not controlled for
Google Maps ranking factors include proximity of the business to the searcher's location. Searches were conducted without location spoofing, which means businesses geographically closer to the search origin may have appeared in the local pack independently of their review profile. This introduces a confounding variable that cannot be fully eliminated without location-controlled methodology.
Correlation, not causation
The benchmark data establishes that businesses with certain review counts tend to appear in the local pack. It does not prove that achieving those review counts causes local pack placement. Review count correlates with other signals (business age, profile completeness, citation volume) that also influence ranking.
7 categories, not all trades
The study covers HVAC, plumbing, roofing, electrical, painting, landscaping, and general contracting. Thresholds for other trade categories (pest control, pool service, flooring, etc.) were not measured and should not be extrapolated from these figures.
