The Manual Method (Free but slow)

The most obvious way to find these businesses is directly on Google Maps.

1. Open Google Maps and type a local query (e.g., "Plumbers in Austin, TX").
2. Look at the pins on the map.
3. Click the first pin. Look at the information panel on the left.
4. Does it have a global "Website" icon next to the "Directions" icon? If yes, skip to the next pin.
5. If the "Website" icon is missing, you have found a prospect.
6. Log their name and phone number in a spreadsheet.

The problem: This process takes roughly 15-20 seconds per business. To find 50 qualified prospects, you will spend about 3 to 4 hours doing mind-numbing data entry.

The Chamber of Commerce Method

Many local Chambers of Commerce offer member directories on their website.

You can export or scrape these directories. Because they usually have dedicated columns for Name, Phone, and Website, you can easily sort the Excel file to highlight the blank rows in the Website column.

The problem: The data is often wildly outdated, and many of those businesses may have gone bankrupt years ago.

The Automated Method (Fernly)

Instead of spending 4 hours clicking on maps, you can use specialized discovery engines like Fernly to do this instantly.

Fernly integrates with live web data. When you type "Plumbers in Austin, TX" into Fernly:

• It pulls hundreds of live business profiles in seconds.
• You simply toggle the "No Website" filter.
• The list instantly filters down to the 20 plumbers missing a website.
• You click "Claim" to add them to your CRM.

What takes 4 hours manually takes roughly 45 seconds using Fernly.
