Google Maps in 2026 is fundamentally different from two years ago. The introduction of AI Overviews in search results, the integration of Gemini into the search algorithm, and the accelerated adoption of voice search have dramatically changed the local search landscape. In this article, we share the most current insights from our experiments — based on data from more than 340 geo-grid measurements on 47 Dutch businesses between October 2024 and April 2026.
Why 2025 knowledge hurts you in 2026
Most Local SEO guides you find online were written in 2023 or 2024. They advise you to focus on three factors: relevance, prominence, and proximity. These three pillars are still relevant, but the way Google weighs them has changed dramatically. A strategy that worked in 2024 — collecting lots of reviews, completing your GBP, and building backlinks — is a necessary but insufficient foundation in 2026. What really makes the difference are nine factors we have identified and measured in our experiments.
Ranking Factor 1: GBP Profile Completeness (weight: high)
A fully completed Google Business Profile has been the starting point of every Local SEO strategy for years, but in 2026 the definition of “complete” has expanded. Google added new fields to GBP profiles in Q3 2025 for service businesses, hospitality, and healthcare. Businesses that filled in these new fields saw an average position improvement of 2.4 in the Local Pack within 21 days after completing them — without making any other changes.
Specifically: expanded service listings with price ranges, an updated “more information” section with FAQ-like content, and active use of the new “highlights” feature launched in November 2025. Businesses using the highlights feature appear 34% more often in Knowledge Panel results on mobile.
Ranking Factor 2: Review Velocity and Sentiment Analysis (weight: high)
Google has been analyzing review content for years, but in 2026 the sentiment analysis has been significantly refined. Reviews describing specific services, locations, or experiences carry more weight than generic positive feedback. In our experiment with eight Amsterdam restaurants, businesses whose reviews described specific dishes, atmosphere, and service averaged 3.1 positions higher than restaurants with comparable numbers of reviews but generic feedback (“great restaurant, highly recommended!”).
Even more important is review velocity: the speed at which new reviews come in. Google rewards businesses that consistently receive new reviews far more than businesses with a large historical review volume but little recent activity. In our dataset: four to eight targeted reviews per month outperforms a competitor with 200 reviews but no activity in the past three months.
Ranking Factors 3-9: The Measurable Signals
Website-GBP relevance match (factor 3): Google actively compares your website content with the categories and services in your GBP. A plumber who lists “boiler installation” as a service in their GBP but has no dedicated page for that service on their website misses a significant relevance signal. Businesses that exactly mirror their website structure to their GBP service listings scored an average of 2.8 positions higher in our experiments.
GBP engagement (factor 4): Posts, Q&A interactions, and messaging activity are engagement signals Google uses to measure a business’s relevance and activity. Posts that generate CTA clicks score measurably higher than posts without engagement.
Core Web Vitals (factor 5): Businesses whose website has poor LCP or high CLS are disadvantaged in the Local Pack compared to competitors with technically equivalent GBPs but better Core Web Vitals. In our A/B test improving website performance for five businesses, we saw an average Local Pack improvement of 1.2 positions.
Photo engagement (factor 6): Both total photo views and click-through rate to photos count as engagement signals. Businesses uploading high-quality new photos monthly scored significantly better.
Service area specificity (factor 7): Service businesses setting their service area at neighborhood level saw an average 2.3-position improvement in border zones of their service area.
Message response time (factor 8): Businesses with response times under one hour scored structurally higher than businesses with longer response times.
Local citation quality (factor 9): In 2026, citation quality matters more than quantity. Fifteen to twenty high-authority, sector-specific citations outperform a volume approach with fifty generic directory listings.
