How to Put Multiple Locations on a Map (Step-by-Step Tutorial)
How to Put Multiple Locations on a Map: The Technical Guide
Need to visualize multiple addresses on a single map? Whether you’re showing store locations, event venues, delivery areas, or property listings, displaying multiple points on a map requires specific techniques. Here’s the working method using Google Maps Platform.
Method 1: Using Google Maps JavaScript API with Custom Markers
This approach gives you complete control but requires programming knowledge and API setup.
Step 1: Set Up Google Cloud Project
- 1. Visit [Google Cloud Console](https://console.cloud.google.com/)
- 2. Create a new project (e.g., “Multi-Location Visualizer”)
- 3. Enable billing ($200 monthly free credit for most use cases)
- 4. Enable these essential APIs:
- – Maps JavaScript API (for the interactive map)
- – Geocoding API (to convert addresses to coordinates)
- – Places API (for search functionality)
Step 2: Generate and Secure Your API Key
- 1. Go to Credentials → Create Credentials → API Key
- 2. Immediately restrict to prevent security issues:
- – Application: HTTP referrers
- – Website restrictions: `*.yourdomain.com/*`
- – API restrictions: Select only the three APIs you enabled
Step 3: Create the Map with Multiple Locations
Create `multiple-locations-map.html` with this complete code:

Code language: HTML, XML (xml)Step 4: Deploy and Customize
- 1. Replace API Key: Insert your actual Google Maps API key
- 2. Customize Data: Replace the sample locations with your own data
- 3. Style Adjustments: Modify CSS colors to match your brand
- 4. Add Features: Implement clustering for many markers (>100 locations)
- 5. Embed: Add to your site via iframe or direct integration
The Challenges of This DIY Approach
While technically impressive, this method has significant drawbacks:
1. API Complexity: Managing quotas, billing, and key security
2. Data Management: No built-in database for location storage
3. Scalability Issues: Performance degrades with 100+ markers
4. Maintenance Burden: Constant updates for API changes
5. Mobile Optimization: Requires additional responsive design work
6. No Admin Interface: All changes require code modifications
7. Limited Collaboration: No team editing or permission controls
