I Spent $37 on Google Maps API and Got 14,000 Leads
How I used Google Maps Text Search to build a prospect list of 14,000 small businesses with websites but no chatbot.
When you're building a product for small businesses, your first problem isn't building the product. It's finding the businesses.
I needed a list of local businesses with websites. Specifically: businesses that get website visitors but don't have any chat or automated response on their site. Potential DropBot customers.
Buying lead lists felt wrong - expensive, outdated, and full of junk. So I built my own.
The Google Maps Approach
Google Maps knows every local business. It has their name, address, phone number, website, category, ratings, and hours. And Google offers an API to search it.
The Text Search API lets you search for things like "yoga studio in Austin" or "plumber in Chicago" and get back structured data. Including the website URL.
I wrote a script that searched for service businesses across 50 US cities. Salons, clinics, repair shops, studios, tutors, restaurants, dental offices - any category where a chatbot could help.
The Numbers
- Searches run: ~800 queries across categories and cities
- Raw results: ~22,000 businesses
- With websites: ~14,000
- API cost: $37.42
That's $37 for 14,000 qualified leads with business name, category, city, and website URL. Try getting that from a lead vendor.
What I Did With the List
For each website, I ran a quick check: does this site have a chat widget? I looked for common chat tool signatures - Intercom, Drift, Tidio, LiveChat, Zendesk. About 85% had no chat at all.
That gave me roughly 12,000 businesses with websites, no chat widget, and a clear potential use case for DropBot.
What Worked and What Didn't
I started emailing them. Cold outreach, personalized by industry. "Hey, I noticed your [yoga studio/dental clinic/plumbing business] website doesn't have a way to answer visitor questions after hours."
The results were mixed. Open rates were decent (30-35%). Reply rates were low (2-3%). Most small business owners are drowning in cold emails from SEO agencies and ignore anything that smells like sales.
What worked better: using the list to understand which industries respond best, then focusing content and SEO on those industries. The list became a research tool, not just an outreach list.
The Takeaway for Other Founders
If you're selling to small businesses, Google Maps API is the most underrated lead generation tool available. For the cost of a lunch, you get a structured database of every business in your target market.
The hard part isn't finding them. It's earning their trust. But you can't earn trust if you don't know who to talk to. $37 solved that problem.
