Why I Still Buy Drive-Time Spots When Everything Else Can Be Tracked
I spent the better part of 2019 trying to optimize a local retail campaign exclusively through social and search. The ROAS looked good on paper. The client kept asking why phone calls weren't moving. I went back to radio for the last six weeks of that campaign, ran drive-time spots only, and watched the call volume tick up enough to cover the media spend within three days. That's the thing nobody writes about. You can measure digital clicks all day long. But drive-time radio hits people in a context where they're actually able to act on what they hear. Drive time is between 6 AM and 10 AM, then 3 PM to 7 PM. That's when the majority of car commuters are tuned in. People are stuck in traffic, they're not scrolling their phones, and they're listening to the same stations week after week. That repetition builds something digital ads struggle to replicate without burning through budget. The conundrum isn't that radio is better than digital. It's that radio fills a gap most media plans ignore until it's too late. Most people buy drive-time slots wrong. They order a 30-second spot and walk away. That doesn't work. You need a flight plan that accounts for frequency and timing. Here's what I use as a baseline for a mid-market campaign:
A four-week flight, Monday through Saturday, with spots rotated between two or three stations in the same market. Each station gets roughly eight to twelve spots per week during drive time. That puts you at about 32 to 48 total impressions per week per station. The cost per thousand impressions, or CPM, usually runs between $8 and $15 for drive time in most markets. A typical four-week flight for a small business might sit between $4,000 and $8,000 depending on the market size and how competitive the station is. The key is frequency. People need to hear your message at least three times before they'll remember it. A single spot drops off the moment the car turns into a parking lot. Eight to twelve spots per week means a listener hears you on multiple days, which is different from hearing one spot eight times in a row. That difference matters for recall.
The Edge Case That Almost Made Me Quit Radio Completely
Back in 2021, I ran a campaign for a plumbing company in a suburb where the drive-time demographics were skewed older. The client was getting zero call tracking returns from the digital side. I set up a dedicated call-tracking number on the radio spots and ran the flight for three weeks. The calls came in, but the timing was wrong. Most calls happened between 11 AM and 1 PM, not during the drive-time window when the spots aired. The audience was listening, but they weren't calling until later in the day. The workaround was simple but easy to miss. I shifted the flight to include morning drive and midday slots between 10 AM and 2 PM. Call volume doubled in the next three-week flight. The lesson was that drive time isn't always the best time, depending on who you're targeting. For a plumber, the relevant audience might be home during the day, not commuting. If you're selling something to working parents, drive time still works because they're the ones making the decision while stuck in traffic.

What People Get Wrong About Measuring Radio
Digital gives you click-through rates, conversion windows, and attribution models. Radio gives you call volume and sometimes a branded lift study. Those aren't the same thing, and expecting them to be is where most campaigns fail. The standard workaround is a unique phone number on the creative, tracked through a CRM or call-tracking platform like CallRail or HyperTrack. You can also use promo codes if you're running a product campaign, though that's less common for service businesses. The counter-intuitive part is that even untracked radio spots can move the needle. If you run drive-time spots for six weeks and your website traffic from direct visits goes up, or your branded search volume increases, that's radio working. You just won't see it in a conversion report. I've seen this happen repeatedly with local HVAC companies during peak season. Their digital channels showed flat performance while radio was pulling in enough overflow calls to keep the trucks on the road.
The Real Limitations You Need to Know Before You Commit
Radio doesn't scale the way programmatic ads do. You can't tweak a creative every hour based on performance data. If your spot flops, you're stuck with it until the next flight cycle. Production quality matters more here than anywhere else because the medium is audio-only. A poorly recorded voiceover with background noise will get ignored in three seconds. Budget-wise, drive-time slots in top markets like New York or Los Angeles can run $500 to $1,200 per spot. That adds up fast if you're buying a heavy flight across multiple stations. The other limitation is geographic reach. If your business operates across a metro area, you need to make sure the stations you're buying cover the right zip codes. Some markets have stations that sound like they're local but only reach one corner of the city. I learned this the hard way with a real estate client who thought they were buying a market-wide flight. Half the spots only reached the northern suburbs. The fix was to request Nielsen Arbitol data or the station's own audience maps before signing the buy. Always ask for the station's demo breakdown and DMA coverage.
When Radio Makes Sense and When It Doesn't
Drive-time radio works well for local service businesses, retailers with a physical location, and brands that need awareness in a specific market. It's less effective for e-commerce businesses without a local angle, B2B companies, or products that require detailed explanation beyond 30 seconds. If your sales cycle is longer than a week, digital nurtures the lead better. If someone hears your spot and needs to research before buying, they'll forget where they heard it by the time they're ready to pull the trigger. For immediate action businesses like towing, emergency plumbing, or urgent care clinics, drive time is still one of the most efficient channels available. The audience is captive, the message is simple, and the decision is usually made on the spot. I've run campaigns where a single flight generated more qualified calls than three months of Google Ads at half the cost. That's not common, but it happens often enough that I still recommend radio for the right clients.
Practical Steps to Run Your First Flight
Start by identifying your market and the stations that dominate drive-time listenership. Most radio groups have online rate cards, but those numbers are inflated. The actual cost is usually 40 to 60 percent lower once you negotiate or work with an independent media buyer. Reach out to two or three stations and ask for their drive-time demo and available packages. Get the flight details in writing, including which days, times, and stations are covered. Next, write the creative. Keep it under 30 seconds. Lead with the problem, not the feature. A plumbing ad that opens with "Your water heater just blew" works better than one that starts with "We've been serving this community since 1998." Include a clear call to action with a tracked number. Test two versions if the budget allows, then double down on what moves the metrics. After the flight runs, pull the call data and compare it to your baseline. If the numbers are there, repeat the flight with adjustments. If they're not, look at the audience data and see whether the mismatch was demographic, geographic, or creative. The process usually takes about two weeks from initial outreach to first air date if you move quickly. Delays happen when you wait on creative approval or when the station has already sold out the slots you want. Lock in your buy early, especially if you're targeting a specific season.
A Note on Digital Integration
The best radio campaigns don't exist in isolation. Pair drive-time spots with a landing page that matches the message in the ad. Use the same tracking number on both the radio spot and your digital ads so you can see which channel is driving the action. Run a retargeting campaign for people who visited the landing page but didn't call. This setup costs a bit more in management time, maybe two to three hours per flight, but it gives you a much clearer picture of what's actually working. Without it, you're guessing. With it, you know whether radio is filling the top of your funnel or just generating noise.
