Generate Leads with Google Maps - AlexK1919
This workflow automatically searches for business location information in a specified area by calling the Google Maps API, and writes the deduplicated data (such as name, address, phone number, rating, etc.) into Google Sheets, significantly improving the efficiency of potential customer acquisition. The built-in retry mechanism ensures stability under API call limits, making it suitable for marketing teams, sales personnel, and data analysts, thereby supporting precise marketing and business decision-making.
Workflow Name
Generate Leads with Google Maps - AlexK1919
Key Features and Highlights
This workflow automatically searches and collects business location information within specified subcategories and postal code areas by leveraging the Google Maps API. After deduplication, it writes comprehensive business data—such as name, address, phone number, rating, reviews, website links, and social media information—directly into Google Sheets, enabling efficient and automated lead generation. The workflow incorporates a multi-level exponential backoff retry mechanism to intelligently handle API rate limits, ensuring data retrieval stability and completeness.
Core Problems Addressed
- Manual lead data collection is time-consuming, labor-intensive, and prone to errors.
- API call frequency limits cause interruptions in data scraping.
- Complex deduplication and status management make it difficult to maintain data accuracy.
- Integrating multi-dimensional business information is challenging, impacting subsequent marketing and analysis.
Use Cases
- Marketing teams rapidly generate accurate bulk lead lists.
- Sales personnel efficiently acquire business contact data for target areas.
- Data analysts build local business databases to support informed decision-making.
- Automation enthusiasts and developers explore Google Maps data integration applications.
Main Workflow Steps
- Trigger Start: Manually initiate the workflow via a trigger.
- Configuration Reading: Read target postal code lists and subcategory settings from Google Sheets.
- Data Filtering: Exclude postal codes and subcategories that have been processed or marked to ignore.
- Iterative Processing: Sequentially call the Google Maps Places Search API for each postal code and subcategory combination.
- Empty Result Handling: If the API returns no results, proceed to the next subcategory.
- Data Splitting: Break down the returned location list into individual data entries.
- Deduplication: Remove duplicates based on place_id to avoid redundant entries.
- Data Storage: Append or update lead data in Google Sheets and update processing status accordingly.
- Exception Retry: Employ an exponential backoff algorithm to handle API rate limits and call failures, retrying up to 5 times.
- Error Termination: If the maximum retry count is reached without success, stop the workflow and display an error notification.
