NAB/RAB Issue Commercial Frequency Guidelines


How Many Radio Ads Should You Run Per Week?  The answer always starts the same: “It depends. What is your goal?”
According to a Piere Bouvard blog post, the Radio Advertising Bureau (RAB) fields this question daily. 
To help advertisers and agencies get it right, Cumulus Media | Westwood One partnered with the RAB to establish clear, research-based guidelines built around four distinct campaign objectives. These tiers—Minimum (Very Light), Maintenance (Light), High Impact (Medium), and Launch (Heavy)—are defined by weekly reach and average frequency against a radio station’s audience.



Key Insights Most Advertisers Miss
  • Agencies and radio sellers routinely underestimate what it takes to achieve meaningful impact. Most campaigns fall into the Minimum/Very Light category, reaching only about one-third of the station’s audience.
  • The Wizards of Ads—one of the most successful local radio agencies in the country—strongly recommends the High Impact/Medium schedule as the ideal “always-on” approach: reaching two-thirds of a station’s audience an average of three times per week, 52 weeks a year.
  • Media Monitors data confirms that only a small fraction of American radio schedules reach High Impact or Launch levels. The vast majority stay in the ineffective “very light” zone.
  • iHeartMedia’s attribution study shows a clear lift in auto dealer website traffic as the number of daily radio ads increases. Campaigns that span all days and dayparts deliver the strongest results.
The number of ads needed to achieve each of the four levels of radio station reach vary by AM/FM radio programming format





















Bottom Line
  • Radio advertising is not one-size-fits-all.
  • Want quiet, low-cost maintenance? Use a Light schedule.
  • Running a weekend sales event? You probably need Medium.
  • Launching something big or need to dominate the market? Go Heavy.
Understanding your specific goal is the first and most important step in building an effective AM/FM radio media plan. The right number of ads isn’t about spending more—it’s about spending smart.
