When someone searches "plumber near me" or "best dentist in city," Google typically shows three local businesses in a map-based section before the organic search results. This is the local 3-pack, and the businesses in it receive a disproportionate share of the clicks, calls, and customers.
According to research from BrightLocal, those three positions collectively capture 44% of all clicks from a local search results page. The businesses outside that box — even if they're ranked 4th or 5th — get dramatically less traffic.
Here's how to understand what drives who gets in, and specifically how reviews factor into the algorithm.
What the Local 3-Pack Is
The local 3-pack appears as a map widget at or near the top of Google search results for queries with local intent. Each listing shows:
- Business name
- Star rating and review count
- Address and distance from searcher
- Business category or service type
- A link to directions and to the full Google Business Profile
When someone clicks a listing, they land on the business's full GBP (formerly Google My Business) profile, where they can call, get directions, read reviews, and visit the website.
This is why GBP optimization — and reviews specifically — matters so much. The local pack puts your profile front and center before your website is ever seen.
The Three Ranking Factors Explained
Google has publicly stated that local ranking is based on three primary factors: relevance, distance, and prominence.
Relevance
How well does your business match what the searcher is looking for? Relevance is determined by your GBP category, your business description, the keywords in your reviews, your services list, and the content on your website.
If you're an HVAC company, choosing the right primary category ("HVAC Contractor" vs just "Contractor") matters. So does listing your specific services (AC repair, furnace installation, emergency HVAC) within your GBP.
Distance
How close is your business to the searcher's location? You can't control your physical address, but you can control your listed service area (important for mobile/delivery businesses) and ensure your NAP (name, address, phone) is accurate everywhere it appears online.
Prominence
This is where reviews play the biggest direct role. Prominence is Google's assessment of how well-known and reputable your business is. It draws on:
- Number of reviews
- Average star rating
- Review recency
- Review response rate
- Mentions of your business name in other authoritative places (news, directories, links)
- Your website's overall authority
Of these, reviews are the component you can most directly improve through deliberate strategy. Your website's domain authority grows slowly. Review count and velocity can be improved in weeks.
How Reviews Contribute to Prominence
Review count gives Google volume evidence that real people interact with your business. A business with 12 reviews signals limited engagement. A business with 180 reviews signals a well-established, frequently-visited operation.
Star rating correlates with user satisfaction and influences whether users click your listing when they see it. Google accounts for both the absolute score and the recency of ratings.
Review recency (how recently reviews have been posted) is a freshness signal. Google's algorithm appears to weight recent reviews more heavily than older ones. A business adding 8–10 reviews per month looks more active than one with 200 reviews and nothing new in 4 months.
Response rate is increasingly recognized as a ranking signal. Google has confirmed that "replying to reviews shows that you value your customers and the feedback that they leave about your business." Multiple independent studies have found correlation between high response rates and better local pack positioning.
The Review Velocity Factor vs Total Count
A common mistake: assuming that total review count is the dominant review-related ranking signal. It's important, but velocity matters independently.
Consider two businesses:
- Business A: 180 reviews, last review posted 3 months ago, 5 new reviews in the past 90 days
- Business B: 95 reviews, last review posted 4 days ago, 22 new reviews in the past 90 days
Business B is gaining faster, has stronger recency signals, and is likely signaling more prominently to Google's freshness filters. In competitive markets, Business B is often the one that moves into (or stays in) the 3-pack while Business A gradually loses position.
This is why burst campaigns ("send review requests to all your past customers this week") are useful for an initial push but not a substitute for sustained velocity. The best strategy is consistent collection — 5–15 new reviews per month, month after month.
Real Case Study: Moving Into the Local Pack in 4 Months
A residential painting company in a mid-size metro market started with 18 Google reviews at 4.1 stars and was ranking position 7–9 for "house painters city" — well outside the local 3-pack.
Their 4-month strategy:
- Month 1: Connected Laudy, sent review requests to 3 years of past customers. Added 34 reviews in the first month. Rating increased to 4.4.
- Month 2: Automated requests triggered on invoice sent. Added 12 reviews. Started responding to all reviews within 24 hours. Rating reached 4.6.
- Month 3: Added 9 reviews. Updated GBP services list with specific painting types (interior, exterior, cabinet, deck). Responded to a well-written 2-star review professionally.
- Month 4: Added 11 reviews. By end of month, appeared in the local 3-pack for primary keyword. Call volume increased by approximately 60%.
Total reviews at the end of Month 4: 84. Average rating: 4.7. Response rate: 100%.
The combination of volume, velocity, quality, and response rate pushed them into the 3-pack past competitors with comparable or higher review counts but lower recency and poor response rates.
The 6-Month Review Strategy for Local Pack Entry
If you're currently outside the local 3-pack, here's a realistic timeline for entry:
Month 1 goal: Close the gap on review count vs the businesses currently in the pack. If they have 60–80 reviews, your target is 40+ by end of Month 1 (using an initial outreach to past customers).
Month 2–3 goal: Achieve parity or superiority in star rating. Maintain 100% response rate. Your review velocity should now be automated and consistent.
Month 4–5 goal: Surpass competitors on review velocity. If they're adding 3 reviews/month and you're adding 10, the algorithm will notice.
Month 6 goal: Local pack entry. This is not guaranteed — proximity and relevance factors also matter. But for most competitive-but-not-hyper-competitive local markets, this timeline produces results.
