# Build a fuller list from several lead sources

> No directory lists every business. Combining sources and removing duplicates gives you far better coverage.

## Why combine

Each source has blind spots. Google Maps has the widest coverage of local businesses. Yelp is strong for restaurants and home services. A roofer might be on both; a new barbershop only on Maps.

## Step 1: Run the same niche everywhere

| Source | How to search |
|---|---|
| Google Maps | Niche + city, country |
| Yelp | Search term + city |

## Step 2: Export with the same layout

Use the same export layout for each (for instance **Instantly** or **Main columns**) so columns line up.

## Step 3: Remove duplicates

Match in this order:

1. **Website domain** — the most reliable key
2. **Phone number** (digits only)
3. **Business name + city** — for businesses without a website

Keep the row with the most data: an owner name, more emails, a rating.

## Step 4: Merge the signals

A business found on several sources gives you more to say: its Google rank, Yelp rating and TrustScore together. Keep those columns side by side for personalisation.

## Step 5: Send as one list

Import the merged file into your sequencer, or send each list with **Send to** and let your tool skip duplicates (Instantly and Smartlead can skip leads already in your workspace).

## Cost

Each list costs one credit per lead found, so overlapping businesses cost a credit on each source. Begin with the source that fits your niche best and add the others where coverage is thin.

## Frequently asked questions

### What is the best way to remove duplicate businesses?

Match on website domain first, then phone number, then business name plus city.

### Do I pay twice for a business found on two sources?

Each source charges one credit per lead it returns, so yes — which is why it helps to begin with the best source for your niche.
