Ever Wondered What Goes Into 30 Seconds of Radio?
You hear them every day. Between songs, during the morning jam, while you’re waiting for your teh tarik. A cheerful voice, a bit of music, a phone number, and it’s over before you’ve finished your sip.
It sounds simple, but a lot happens behind those few seconds. If you’re thinking of trying radio commercials for your business, it helps to know how one actually comes together. Here’s the journey from idea to airtime, step by step.
First, Why 30 Seconds?
Radio spots usually come in three lengths:
- 15 seconds: a quick reminder or a single offer. Good for keeping your name fresh once people already know you.
- 30 seconds: the most common length. Enough time for one clear message without losing anyone.
- 60 seconds: room for a story or a more detailed offer, but it costs more airtime and is harder to keep interesting.
For most local businesses, 30 seconds is the sweet spot. It’s roughly 70 to 80 words, so every line has to earn its place.
Step 1: The Brief
Everything starts with a few simple questions:
- What are you promoting?
- Who should hear it?
- What do you want them to do afterwards?
- Which language will your customers respond to?
- What’s your budget?
Get these answers down in a paragraph or two. A clear brief saves a lot of back and forth later.
Step 2: The Script
A good 30-second script has a simple shape:
- First 5 seconds, the hook. Grab attention fast. A question, a problem or a familiar situation works well.
- Next 15 seconds, the message. Your offer and why it matters. One idea only.
- Last 10 seconds, the action. Say your business name, then tell people what to do next: call, WhatsApp or visit.
Compare two openings. “Welcome to Bengkel Maju, your trusted car service centre.” Or “Balik kampung soon? Get your car checked before you hit the highway.” The second one gets attention, doesn’t it?
Put together, a full script might sound like this (the name and number are made up): “Balik kampung soon? Get your car checked at Bengkel Maju in Klang before you hit the highway. Our team will check your tyres, brakes and oil, so you can drive home with peace of mind. Book this week and get a free tyre check with every service. WhatsApp Bengkel Maju at 012-XXX XXXX. Safe journey starts here.”
Step 3: Choosing the Voice and Language
The voice is the personality of your ad. A cafe might want someone cheerful and quick. A clinic might want a calm, warm voice. Think about who your customers are, not just what you personally like.
Language matters just as much. Malaysia has stations in Malay, Mandarin, Tamil and English, and plenty of listeners switch between them. Some brands record the same radio commercials in two languages and run them on different stations. Others use a natural mix, the way people really speak. Whatever you choose, make sure the wording sounds like a real person, not a translation.
Step 4: Music and Sound
Music sets the mood. Upbeat for a sale, softer for a service business. But it should support the voice, never drown it out. If a listener can’t hear your phone number over the background track, the music is too loud.
Sound effects can help too, like a door bell or a sizzling pan, but use them sparingly. And if you’re using music, ask your producer to make sure it’s properly licensed for broadcast.
Step 5: Recording and Editing
This is where the script becomes a real ad. A voice artist records in a studio, usually with a producer giving direction on tone and pace. Then the editor puts everything together:
- Trimming the recording to fit exactly 30 seconds
- Balancing the voice and music levels
- Cleaning up any breaths, clicks or background noise
- Making shorter cuts, like a 15-second version, if you need them
It’s worth listening to the final version in a car or on a phone speaker, because that’s where most people will hear it.
Step 6: Approval and Delivery
Before anything airs, check the details carefully. Is the business name pronounced correctly? Is the phone number right? Is the offer wording accurate, including any dates or conditions?
Then the finished file goes to the station. Stations have their own requirements for file format and scheduling, so ask what they need early. Don’t leave this to the last week, especially before Raya, CNY or Deepavali, when slots fill up fast.
Step 7: Airing and Tracking
Once the spot goes on air, the schedule takes over. Remember that radio works through repetition, so plan on running it for a few weeks. To see if it’s working, use a promo code or WhatsApp keyword, and ask new customers how they heard about you.
Common Mistakes to Avoid
Most spots that fall flat trip over the same few things:
- Too much in too little time. Three offers in 30 seconds means listeners remember none of them.
- No call to action. If people don’t know what to do next, they’ll just keep driving.
- A voice that doesn’t fit. A stiff, formal read for a fun brand feels off straight away.
- Skipping the read-aloud test. Lines that look fine on paper can sound clumsy out loud.
- Unchecked details. One wrong digit in a phone number can waste an entire campaign.
Catch these early, and you’ll save yourself time and airtime.
Questions to Ask Before You Start
Whether you work with a station’s team or an outside agency, it’s worth asking:
- Who writes the script, and how many revisions are included?
- Are the voice artist and music included in the price?
- Will I get shorter versions, like a 15-second cut?
- What file format and deadline does the station need?
- Can I hear a sample or a draft before it airs?
Final Thoughts
A 30-second radio commercial is short, but it isn’t simple. The best ones come from a clear brief, a tight script, a voice that suits the brand, and a bit of care at every step. Get those right, and the rest tends to fall into place.
