Local radio advertising has been around for nearly a century. B2B marketers still ask about it, and for good reason: radio is everywhere, local markets are accessible, and the idea of reaching commuters during drive time feels intuitive. But does radio actually work for B2B? And how does it stack up against newer audio channels?
This guide breaks down everything: how radio advertising works, what it costs, how iHeart's local network operates, where radio delivers value, and where it falls short for B2B brands.
When you buy local radio advertising, you're purchasing airtime from a station that broadcasts to a defined geographic market. That could be a single city, a metro area, or a cluster of neighboring markets.
Ads on radio come in two main formats:
Most radio buys are negotiated directly with a station or through a radio advertising agency that has relationships across multiple markets. You choose your dayparts (morning drive, midday, evening drive, overnight), your frequency, and your run dates.
The pitch: radio reaches people who are hard to reach online, in cars, on job sites, in warehouses. For consumer brands, this is genuinely valuable. For B2B brands, it gets more complicated.
Radio advertising cost varies a lot based on market size, time of day, and station popularity. Here's a realistic breakdown:
Radio CPM typically runs $10 to $20, which looks competitive on paper. But radio "impressions" are estimates from Nielsen ratings data, not verified listens like a podcast download or a digital ad impression.
Before your ad ever airs, you need to create it. A professional radio spot runs:
This means a B2B brand entering a mid-size market should budget at least $3,000 to $8,000 just to get started, before considering the ongoing media buy.
Some stations offer flat-rate packages: a set number of spots per week for a fixed monthly fee. These are common in smaller markets and can simplify budgeting. CPM-based deals are more common in larger markets where ratings data is more robust.
iHeart advertising is worth understanding because iHeart Media is the largest radio broadcaster in the U.S., operating over 850 stations across more than 160 markets. If you're considering radio advertising at scale, iHeart is probably part of the conversation.
iHeart's local advertising platform lets brands buy across multiple markets from a single point of contact, which solves one of traditional radio's biggest headaches (negotiating separately with dozens of stations). iHeart also has a digital audio arm (iHeart Radio streaming), which gives advertisers access to digital ad placement alongside traditional broadcast.
For B2B brands, iHeart's appeal is reach and simplicity. You can set up a campaign that hits 10 markets simultaneously. The tradeoff: you're still buying broad demographic targeting (adults 25-54, commuters, etc.) rather than the intent-based or job-title-based targeting that B2B needs.
iHeart does offer programmatic and data-enhanced targeting through their SmartAudio product, which layers first-party and third-party data onto ad buys. This narrows the gap somewhat, but it still doesn't get you to "target CFOs in SaaS companies" precision.
Radio isn't worthless for B2B. There are real scenarios where it works:
Local services businesses: Accountants, law firms, IT service providers, and HR consultants serving a specific metro often find radio cost-effective for brand awareness. Decision-makers are also commuters.
Recruitment advertising: If you're a regional employer trying to reach skilled tradespeople, warehouse workers, or local professionals, radio reaches people who aren't scrolling LinkedIn at 7am.
Event promotion: A local B2B conference, trade event, or seminar can use radio to drive registrations in a defined geography where the audience can actually attend.
Brand awareness in established markets: If you already dominate a market and want to keep your name top of mind for a local audience, radio's broad reach can act as a reminder layer.
The common thread: radio works when geography is the primary targeting lever and when the B2B audience overlaps meaningfully with the general commuter population.
Be honest about the gaps. Radio is a poor fit for B2B in most cases:
No intent targeting: Radio can't tell the difference between a small business owner and a teenager. You pay for all of them equally.
No account-based reach: ABM (account-based marketing) is a core B2B strategy. Radio has zero ability to target specific companies, job titles, or industries.
Weak attribution: Radio advertising cost is real, but proving it drove pipeline is hard. Vanity URLs and promo codes help, but they don't capture the full picture.
Wrong audience, wrong mindset: B2B decisions happen at desks, in meetings, and during research sessions, not during the morning commute. A CFO listening to the radio isn't evaluating enterprise software at that moment.
Short format constraints: A 30-second spot can't explain a complex B2B value proposition. It can build awareness, but not conviction.
Here's where it gets interesting. Audio advertising has evolved significantly, and podcast advertising often delivers what radio promises but can't quite achieve for B2B.
Podcast advertising networks connect B2B brands with shows where the audience is already self-selected: IT leaders listening to DevOps podcasts, CMOs listening to marketing strategy shows, finance professionals listening to CFO content. The targeting is built into the format.
Podcast advertising rates run higher on a CPM basis, typically $18 to $50 CPM for host-read ads vs. radio's $10 to $20 CPM. But the qualified reach is dramatically better. You're paying for listeners who opted in to that specific content category, not a broad demographic slice of commuters.
B2B podcast advertising also benefits from format. A 60-second host-read ad in a 45-minute show, delivered by a trusted host to an engaged audience, outperforms a 30-second radio spot almost every time in terms of message retention and listener action.
For brands thinking about national campaigns, podcast ad options for national campaigns cover how to scale podcast buys without sacrificing the targeting precision that makes audio work for B2B.
If you do decide to run radio ads, working with a radio advertising agency makes sense for a few reasons:
The downside: agencies add a management fee (typically 10 to 20% of media spend) and most are optimized for consumer brands, not B2B. If you're a B2B brand working with a general radio agency, push them on B2B-specific benchmarks and attribution approaches.
Before committing to a local radio advertising campaign, run through this checklist:
Radio advertising still has a place in audio marketing. For local B2B brands with a geographic audience, strong brand awareness goals, or recruitment needs, it can be a reasonable investment. iHeart's network makes multi-market buying more accessible than it used to be. And flat-rate packages in smaller markets can make the math work.
But for most B2B brands, especially those selling to specific job titles, industries, or company profiles, local radio advertising is a broad tool trying to do a precision job.
Podcast advertising reaches buyers where they're already engaged with relevant content. Owned podcast content goes further: you build an audience, own the channel, and create a compounding asset that works long after the media buy ends.
At Podsicle Media, we help B2B brands build and grow their own podcast presence instead of renting attention from someone else's platform. If you're weighing radio against audio content, let's talk about what owned media could look like for your brand.
