Is digital audio advertising worth it for local firms?

Quick answer

Digital audio advertising can be worth testing for a local business that has a seasonal or recurring need to be remembered, a simple message and a budget to run for several weeks. It builds awareness rather than instant clicks. Target your area, write a 30-second script that says your name twice, and measure brand searches and calls afterwards.

Audio advertising used to mean commercial radio, with production costs and airtime packages that put it out of reach of most small firms. That has changed. Music streaming services, podcasts and digital radio stations now sell adverts through self-serve tools, with location targeting and budgets small enough for a local business to test. The question is no longer whether you can afford to try audio, but whether audio suits what you sell. This guide covers the options, who they suit, how to write an advert that works, and how to tell whether it did.

The three kinds of digital audio advertising

Streaming platforms such as Spotify Advertising offer self-serve tools for small budgets. Podcast adverts are bought through hosting networks or directly from shows. Digital radio advertising is sold by the commercial radio groups, often with packages aimed at local businesses.

Who audio suits

• Businesses with a seasonal moment: heating engineers before winter, garden centres in spring, tax advisers before the January deadline.
• Local venues and events: a new restaurant, a summer festival, a pantomime.
• Consumer services people need repeatedly: car servicing, dentists, gyms, takeaways.
• Brands with a memorable name or sound that is easy to say and remember.

Who should wait

• Businesses that rely on people searching at the moment of need, such as emergency locksmiths, which usually do better with search ads.
• Firms whose offer needs pictures to understand, such as interior design.
• Very small budgets that cannot run for several weeks; audio needs repetition to work.
• Businesses whose name is hard to spell after hearing it, unless the advert spells it out.

Our guide to measuring marketing return helps you decide whether a test budget is worth it at your size.

How people listen

Audio is heard while people do something else: driving, cooking, working, running. That has two consequences. Your advert competes with whatever they are doing, so it must be simple. And it reaches people at moments screens cannot, such as in the car on the way to the shops. RAJAR, the body that measures UK radio listening, publishes listening figures that show how much time people spend with radio and audio, which is a useful reality check before committing.

Writing a 30-second advert

1. Open with the listener’s situation, not your name: “Boiler making that noise again?”
2. Say who you are, clearly, and say it again before the end.
3. One message. One service, one reason to choose you.
4. One action, easy to remember: a simple web address or a business name to search.
5. Read it aloud and time it. Thirty seconds is about 70 to 80 spoken words.

Avoid phone numbers unless they are very memorable; nobody writes them down in the car. Make the name easy to spell, or spell it. Use a voice and tone that match your brand: calm and reassuring for a dentist, upbeat for a café.

Three example scripts, in outline

A heating engineer, autumn: open with the sound of a boiler struggling, then “Cold mornings are coming. Book your boiler service now, before the rush.” Name, area, “search” the business name, name again.

A new restaurant: open with the sizzle of a grill, a line about what is special, the street it is on and the opening offer, then the name twice and a simple web address.

A dental practice taking new patients: a calm voice, “Looking for a dentist in Harrogate who is taking new patients?”, one reassurance, the practice name twice and how to book online.

Each one has a single message, a local reference and an easy next step. None of them lists services or reads out a phone number.

Budget and frequency

Audio relies on repetition. A listener who hears your advert once may not remember it; hearing it several times over a few weeks is what builds recall. That means a test should run long enough, and in a tight enough area, for the same people to hear it more than once. It is better to cover one town well for six weeks than a whole county thinly for one. Most self-serve platforms let you set a daily or campaign budget and show how many times your advert was played, and to how many listeners. Watch the ratio between the two: if each listener only hears the advert once, your area is probably too wide for your budget.

Podcasts: a closer look

Podcast adverts work differently from streaming adverts. When a host reads your advert in their own words, listeners hear a recommendation from someone they already trust, which can be powerful for the right product. Local podcasts, such as those covering a town’s news, sport or food scene, can be an affordable way to reach engaged local listeners. Ask the show how many people listen in your area, what other businesses have advertised, and whether you can approve the script. Episodes stay online, so a host-read advert in a popular episode can keep being heard for months.

Production

Many platforms offer free or low-cost voice-over and production when you buy adverts, often with a library of music. Podcast hosts may read your advert themselves, which can carry more trust. For radio, stations usually produce the advert as part of the package. Listen to the finished version on a phone speaker and in a car, because that is how most people will hear it.

Targeting locally

Digital audio’s advantage over traditional radio is targeting. Restrict streaming adverts to the towns or postcodes you serve, schedule them for the hours people make decisions (mornings and drive time are popular), and choose audiences that match your customers. For podcasts, local shows and topic-specific shows can be more effective than large general ones. Narrow targeting means fewer plays but less waste.

The rules

Adverts on UK commercial radio are cleared before broadcast through Radiocentre’s clearance service and must follow the broadcast advertising code. Adverts on streaming platforms and podcasts follow the non-broadcast UK advertising code and the platform’s own policies. In every case, claims must be true and provable, prices and offers clear, and any terms stated or easy to find.

Measuring it

Audio adverts are rarely clicked, so do not judge them by clicks. Measure what people do afterwards:

• Searches for your business name, in Google Search Console and your Business Profile insights.
• Direct visits to your website.
• Calls to a number used only in the advert.
• A memorable offer code mentioned only in the advert.
• Asking new customers how they heard of you.

Compare the campaign weeks with the weeks before, and with the same period last year if your business is seasonal. Our guide to website analytics for beginners covers where to find these numbers.

Combining audio with search

Audio works best as the first touch, with search catching the second. Someone hears your advert in the car, then searches for you later. If your Google Business Profile is thin or your website slow, that second step loses them. Before spending on audio, make sure your Google Business Profile is complete and your website makes it easy to get in touch. Running a modest search campaign alongside, bidding on your own business name, catches people who search after hearing the advert.

A worked example

A family-run garden centre in Yorkshire tested streaming audio in early spring, the start of its busiest season. It targeted listeners within fifteen miles, weekend mornings and weekday evenings, with a 30-second advert opening with “First warm weekend? Your garden’s been waiting.” The centre’s name was said twice, along with one simple message about its new plant range and a short web address. It ran for six weeks. Clicks were negligible, as expected. Searches for the centre’s name rose compared with the same weeks the previous year, and several customers at the till mentioned hearing the advert. The centre kept audio for spring and autumn and dropped it in summer, when footfall came anyway.

Common mistakes

• Cramming three messages and a phone number into 30 seconds.
• Running for a week and judging the result.
• Targeting the whole country for a local business.
• Measuring by clicks.
• Neglecting the website and Business Profile people search for afterwards.

Questions to ask before you buy

• How many listeners in my area, and how many times will each hear the advert?
• Is production included, and can I approve the final version?
• What reports will I get, and how often?
• Is there a minimum spend or contract length?

The verdict

Digital audio is worth testing for a local business with a clear seasonal moment, a simple message and the patience to run for several weeks, provided the search and website side is ready to catch the interest it creates. For businesses that depend on urgent searches, put the budget into search first.
