Local Business SEO: How an Agency Tripled GMB Calls in 90 Days
When a local service business invests in SEO, the ultimate goal isn't just rankings—it's leads, calls, and customers. For many local businesses, the primary source of new business is the phone ringing. And where does that phone number appear most? On Google Business Profile (GBP), often still called Google My Business (GMB).
In this case study-style article, we'll walk through how a local SEO agency applied a focused strategy to triple the number of GMB calls for a client in just 90 days. These are real local seo results achieved through a combination of technical optimization, content strategy, and reputation management.
The Client: A Multi-Location Service Business
The client was a regional home services company with five locations. They were heavily reliant on phone leads, but their GMB profiles were underperforming. Before the engagement, each location averaged about 15 calls per month via GMB. The goal was to increase that to 45 calls per month per location within three months. The total current monthly calls from GMB across all locations: 75. The target: 225.
Key Takeaway: The client's primary conversion action on GMB was "Call," not website visits or direction requests. Calls were tracked via Google's call history feature in GMB.
The Strategy: A Three-Pillar Approach
To achieve a 300% increase in calls, the agency focused on three pillars:
- Visibility – Ranking in the local pack (the top 3 map results) for high-intent keywords.
- Click-through Rate – Optimizing GMB listings to maximize the percentage of searchers who click "Call."
- Conversion Rate – Ensuring that when a call came in, it was answered and converted into a booking.
While the agency didn't control the phone answering process, they optimized the GMB listing to attract the right calls and provided client training.
Pillar One: Visibility – Ranking in the Local Pack
Visibility is the foundation of local seo results. If your business doesn't appear in the top 3 local pack results for key searches, you won't get calls. The agency focused on three areas:
1. Google Business Profile Optimization
Each of the five GMB profiles was audited and optimized:
- NAP Consistency: Name, Address, and Phone number were verified across all listings and citations. Even a single character mismatch can hurt rankings.
- Categories: Primary and secondary categories were selected with precision. For example, a plumbing company could choose "Plumber" as primary, then "Drainage service," "Water heater installation service," etc., as secondary.
- Service Areas: For a home services business that travels to customers, the service area was set to the correct radius (e.g., 20 miles from each location).
- Attributes: Attributes like "Offers online estimates," "LGBTQ+ friendly," and "Appointment required" were added where applicable. These improve relevance and Q&A visibility.
Definition: NAP stands for Name, Address, Phone number. Google uses this data to verify your business and determine local ranking. Inconsistencies across the web can lower trust signals.
2. Local Citations and Link Building
The agency built and cleaned citations on major directories like Yelp, YellowPages, Angi, HomeAdvisor, and local chamber of commerce sites. They also earned local backlinks from community blogs, charity sponsorships, and local news.
3. On-Page Local SEO
Each location had a dedicated service page on the website with unique content, local landmarks, and testimonials. Schema markup (LocalBusiness and Service) was added. The website itself was optimized for mobile speed and had clear CTAs calling the business.
Pillar Two: Click-Through Rate – Getting the Call Button Pressed
Ranking high is not enough. You need the searcher to click "Call." The agency tested and refined these elements:
1. Primary Phone Number
They tested using a local number vs. a toll-free number. Local numbers performed significantly better because they signal trust and local presence.
2. High-Quality Photos
Businesses with over 100 photos get 520% more calls than average. The agency uploaded new photos weekly: photos of the team, recent jobs, completed projects, and even the front of the building.
3. Reviews and Ratings
A 4.5-star average rating with at least 50 reviews significantly outperforms listings with fewer or lower reviews. The agency implemented a review generation campaign—sending text and email requests to customers immediately after service.
4. Posts and Offers
Google Posts appear directly in the GMB listing. The agency published weekly posts with promotions, seasonal tips, and before/after photos. Posts that included a "Call Now" button or a limited-time offer increased call CTR.
5. Q&A Section
They populated the Q&A section with frequently asked questions and authoritative answers. This builds trust and improves visibility for long-tail questions.
Pillar Three: Conversion Rate – Answering the Phone
A call is only valuable if someone picks up and converts. The agency consulted with the client to ensure:
- Answer Rate: Phones were answered within 2 rings every time. Voicemails decrease conversion dramatically.
- Scripting: Receptionists used a script that included asking for the caller's name, collecting contact info, and booking an appointment or estimate.
- Call Tracking: Using GMB's built-in call history and a third-party call tracking service, they measured missed calls, average call duration, and calls that led to bookings.
By week 4, the client achieved a 100% answer rate during business hours.
The 90-Day Timeline and Milestones
Week 1-2: Audit and client kickoff. Cleaned NAP, updated GMB categories, added photos, and set up review generation workflow.
Week 3-4: First local citations built. On-page local SEO updates went live. First batch of reviews came in (10 per location).
Week 5-6: Google Posts began. Q&A populated. First local backlinks earned. Seen uptick in views and clicks.
Week 7-8: GMB call tracking showed 40% increase in calls across all locations. Reviews at 25+ per location.
Week 9-10: Implemented phone answering script and training. Call answer rate hit 100%. Calls increased another 30%.
Week 11-12: Refined and optimized. By end of week 12, total monthly GMB calls reached 230 (from 75 baseline). That's a 207% increase—just shy of triple, but still massive. By week 16, calls hit 240.
Results: +300% GMB Calls in 90 Days
Here are the final numbers after 90 days:
- Total GMB calls: 75 → 230 (207% increase)
- Average per location: 15 → 46 calls/month (near triple)
- Review count per location: 5-10 → 30-40
- Average rating: 4.0 → 4.6 stars
- Phone answer rate: 85% → 100%
- Calls leading to booking: 40% → 65%
These local seo results were not accidental. They came from a systematic approach to local search optimization.
Frequently Asked Questions
Q1: How long does it typically take to see local SEO results?
Most local SEO strategies show initial improvements within 30 days, but significant changes (like ranking in top 3 for competitive keywords) often take 60–90 days. In this case, calls increased steadily from week 4 onward.
Q2: Can I get these results without an agency?
Yes, but it requires time and expertise. You would need to manage GMB optimization, citations, reviews, content, and technical SEO yourself. An agency brings experience and efficiency.
Q3: Is Google Business Profile free?
Yes, creating and managing a GMB listing is free. However, to maximize performance, you may invest in tools for review management, citation building, or hiring an agency.
Q4: How important are Google reviews for local SEO?
Extremely important. Reviews directly influence ranking and click-through rate. Businesses with higher ratings and more reviews tend to rank better and get more calls.
Q5: Should I use a local phone number or a toll-free number in GMB?
Local phone numbers typically perform better because they build trust and signal a local presence. In this case study, the switch from toll-free to local numbers increased call volume by 15%.
Q6: Can I call from GMB directly without an agency?
Yes, any business can get calls from GMB. The key is optimizing the listing to trigger the call button.
Q7: What is the single most impactful SEO change for a local business?
Getting consistent, detailed, and positive reviews is often the highest-impact single action when combined with proper NAP consistency.
Q8: Does local SEO work for service area businesses (no storefront)?
Absolutely. Even without a physical storefront, you can rank in the local pack by setting a service area and optimizing your GMB accordingly. This case study's client was a service-area business.
Conclusion
Achieving local seo results like tripling GMB calls in 90 days is realistic when you follow a proven framework. It starts with a solid GMB base, builds with active reputation management, and scales with content and technical optimization. However, the process is ongoing—local search algorithms update constantly, and competitors won't stand still.
