Most web designers who do local prospecting already know that Google Maps is useful. What they do not do is use it systematically. They run a search, look at a few profiles, click through to some websites, and move on. That approach works but it is slow and inconsistent.

This guide covers how to use Google Maps as a proper prospecting tool, including the manual approach and when it makes sense to automate it.

Why Google Maps works for this

The core reason is simple: local businesses have to be on Google Maps to get found. A plumber in Sheffield who has never touched LinkedIn still has a Google Business Profile because their customers search on Google. That profile contains the business name, phone number, category, address, website (if they have one), and review count.

When you are looking for businesses that need a website or better SEO, that information tells you almost everything you need to qualify them in or out before you even make contact.

The manual process

Open Google Maps and search for a business category in a specific location. Something like “electricians in Bristol” or “beauty salons in Leeds”. You will see a list of results in the sidebar.

For each result, you are looking for a few things:

• No website link in the profile. This is your clearest signal. The business has enough customers to set up a Google profile but has not bothered with a website.
• A weak or outdated website. Click through and spend ten seconds on it. Is it mobile-friendly? Does it load quickly? Does it look like it was built before 2015? Those are all pitch angles.
• Low review count. A business with three reviews and a 4.2 rating has not invested in their online presence. They may be open to help.
• No photos or incomplete profile. Signals low engagement with their digital presence overall.

When you find a promising prospect, note down the business name, category, phone number, and any contact info visible on their website. Build a simple spreadsheet and work through it methodically.

The limits of doing this manually

The manual approach works. The problem is speed. Going through one city and one business category properly takes a couple of hours. If you want to cover multiple cities, multiple categories, and build a pipeline of 50 or 100 qualified prospects, you are looking at days of work just on prospecting before you have written a single email.

There is also a consistency problem. When you are doing this manually after a long client call, you get less thorough. You skip businesses you would have clicked on earlier. The quality of your pipeline varies based on how you felt that afternoon.

When to automate it

Automation makes sense when prospecting is a regular part of your week rather than an occasional task. If you are actively trying to grow your client base and you want a consistent flow of leads, doing this by hand every week is not sustainable.

Tools that pull from Google Places data can run through hundreds of businesses in a city in minutes, apply filters (no website, minimum review count, specific categories), and surface only the ones worth your time. You still do the outreach yourself, but the scouting part happens automatically.

Putting it into practice

Whether you go manual or automated, the workflow is the same. Pick a city. Pick a category. Filter for weak web presence. Build a list. Reach out.

The category choice matters more than most people think. Trades (electricians, plumbers, builders) and health services (physios, dentists, opticians) tend to have the highest proportion of businesses with outdated or missing websites. Restaurants are a mixed bag. Professional services (accountants, solicitors) vary a lot by firm age.

Start narrow. Pick one city and one category you know well. Build a list of 20 prospects and write personalised outreach for all of them before expanding. It is better to go deep on a small list than shallow on a large one.
