Typing "dentists in Germany" into Google Maps gives you a handful of results clustered around one area. The map only shows what fits the current view and a capped results list, so a single country-wide search never returns the whole country. To get real coverage you have to break the country into pieces small enough that each search returns everything, then stitch the pieces back together.
Here is a method you can start today.
Step 1: Define one niche and its keyword set
Pick one business type per run. Mixing "plumbers" and "electricians" makes deduping and writing emails harder later.
Then list every way that business describes itself on Maps. For plumbers that might be:
- plumber
- plumbing service
- emergency plumber
- heating and plumbing
- drain cleaning
Search a few of these manually in one city and look at the categories businesses use. Add any you missed. More keyword variants catch businesses that picked an unusual category, and duplicates get removed later anyway.
Step 2: Build your location list
This is the part that decides your coverage. Write down locations at the right level for the country's size:
- Small countries: every town above a few thousand people is usually manageable.
- Mid-sized countries: all cities plus regional towns.
- Large countries: go region by region (states, provinces, counties), then cities inside each.
A practical rule of thumb: big cities need splitting further. A search for "plumber in London" will stop short, while "plumber in Croydon", "plumber in Camden" and so on each return a fuller set. Use districts or boroughs for any city where a test search seems to stop early.
Keep the list in a spreadsheet with a column for region. You will use it to track progress and to segment later.
Step 3: Run the searches in batches
Multiply keywords by locations and you quickly get hundreds of searches. Doing that by hand is where most attempts die.
In GetClient the Google Maps scraper takes bulk keywords and several cities at once, searching live, so you can paste your keyword set and a batch of 20 or 30 locations per run. Each lead can include business name, category, address, phone, website, emails found, the owner's name and title with a confidence score, and social profiles where those are public.
Work through the country in region-sized batches:
- Run one region.
- Save results into a folder named after that region in My Leads.
- Tick the region off in your spreadsheet.
- Move to the next.
Batching by region makes it easy to spot gaps and to pause and resume without losing track. Credits are used as you scrape, so check plans and credits before you plan a very large country.
Step 4: Check coverage before you trust it
Once a region is done, spot-check it:
- Pick three small towns and search Maps manually. Are those businesses in your list?
- Sort by city. Any town with zero results that should have some needs a re-run, maybe with a nearby larger town name.
- Look at the category column for junk (suppliers, shops, unrelated trades) and filter it out.
It is far cheaper to fix gaps now than after you have written a campaign.
Step 5: Dedupe and clean
Overlapping cities and keyword variants mean the same business appears several times. Remove duplicates by website domain first, then by phone number for businesses without a site. Chains with many branches may share one email, so decide whether you want one contact per brand or per branch.
Next, look at the emails themselves. Addresses like info@ or office@ are role-based emails; they are fine to keep but often reach a shared box, so prefer an owner's address when one was found. Some domains accept mail for any address, called catch-all domains, which makes verification less certain.
Run email verification on the list before sending. A country-wide list built from many sources will contain dead addresses, and bouncing them hurts the sending accounts you rely on.
Step 6: Segment by region and size
A whole country is not one audience. Split it so your emails can be specific:
- By region or city: lets you use {{params.city}} honestly and send in local business hours if the country spans time zones.
- By category: an emergency plumber and a bathroom fitter care about different things; {{params.category}} helps here.
- By signal: businesses with no website, or with an owner name found, often deserve different copy.
The guide on how to segment leads for campaigns goes deeper on this.
Step 7: Send in waves, not all at once
A large list tempts people to blast it. Don't. Start with one region, watch replies and bounces, adjust, then roll out.
In GetClient you can send from your connected Gmail or SMTP accounts, set weekday send limits, and build follow-ups that branch on If Opened or If NOT Opened. Use merge tags written exactly as {{params.name}}, {{params.firstname}} and {{params.city}}. Every email carries a one-click unsubscribe link, and unsubscribed addresses are skipped automatically, which matters more as your list grows.
Before the first wave, run through the cold email launch checklist and read the common cold email mistakes that kill replies. Rules on emailing businesses differ between countries, so check what applies where you and your recipients are; this is not legal advice.
A quick plan for this week
- Day 1: pick the niche, build keywords, build the location list.
- Day 2 to 3: scrape region by region into folders.
- Day 4: spot-check coverage, dedupe, verify.
- Day 5: segment and launch the first region.
You end up with a list you know is complete, not one you hope is.
