What is Reach and Frequency?
Reach and Frequency explained clearly with real-world examples and practical significance for marketers.
Reach and Frequency is a fundamental advertising measurement that tracks how many unique people see an advertisement (reach) and how many times they see it (frequency) within a specific time period.
What is Reach and Frequency?
Reach represents the total number of unique individuals exposed to an advertising message during a campaign period, typically expressed as a percentage of the target audience or as an absolute number. Frequency measures the average number of times each person within the reach sees the advertisement.
The basic formula connects these metrics through Gross Rating Points (GRP):
GRP = Reach × Frequency
For example, if a television campaign reaches 40% of the target audience with an average frequency of 3.5 exposures, the campaign generates 140 GRP (40 × 3.5 = 140). This calculation helps media planners compare different campaign strategies and optimize budget allocation.
The Diminishing Returns Problem
Reach typically follows the law of diminishing returns. The first media placements capture audiences efficiently, but additional placements increasingly target people already exposed to the campaign. A campaign might achieve 30% reach with the first $100,000 spent, but require $200,000 more to reach an additional 15% of the audience.
Frequency distribution reveals audience exposure patterns beyond simple averages. While average frequency might be 3.0, the actual distribution could show:
- 50% of the reached audience saw the ad once
- 30% saw it three times
- 20% saw it seven times
This distribution impacts campaign effectiveness more than the average frequency alone.
Digital vs. Traditional Measurement
Digital advertising provides more precise reach and frequency measurement than traditional media. Platforms track individual user exposures across devices and touchpoints, offering detailed frequency caps and reach optimization tools that weren’t available in broadcast-only campaigns.
Reach and Frequency in Practice
Coca-Cola’s “Share a Coke” Strategy
Coca-Cola’s 2019 “Share a Coke” campaign demonstrates strategic reach and frequency planning. The company achieved 70% reach among millennials with an average frequency of 4.2 exposures across television, digital, and out-of-home channels. This combination generated 294 GRP while maintaining cost efficiency by capping individual exposure at eight impressions to prevent ad fatigue.
Nike’s Balanced Approach
Nike’s 2020 “You Can’t Stop Us” campaign targeted 85% reach among sports enthusiasts with 3.8 average frequency. The company allocated:
- 60% of budget to reach-building activities (television and YouTube)
- 40% to frequency-driving tactics (social media retargeting)
This strategy achieved 323 GRP while keeping cost per thousand impressions below $12 across all channels.
P&G’s Launch Formula
Procter & Gamble’s Tide brand typically maintains reach and frequency targets of 80% reach with 5.0 frequency for new product launches. During the 2021 Tide Pods campaign, the company achieved 82% reach and 4.7 frequency among parents aged 25-45, generating 385 GRP. The brand discovered that frequency levels above 6.0 showed diminishing returns in purchase intent metrics.
Spotify’s Viral Efficiency
Spotify’s 2022 “Wrapped” campaign reached 91% of its target audience (music streaming users aged 18-34) with an average frequency of 2.1 exposures. The relatively low frequency reflected the campaign’s viral nature, where organic sharing amplified paid media reach. This approach generated 191 GRP while achieving 47% brand recall, demonstrating how creative execution can maximize impact despite lower frequency levels.
Why Reach and Frequency Matters for Marketers
Reach and frequency optimization directly impacts campaign return on investment by balancing audience breadth with message reinforcement. Campaigns emphasizing reach work best for brand awareness objectives, while higher frequency campaigns suit conversion-focused goals requiring multiple touchpoints to drive action.
Budget Allocation Decisions
Budget allocation decisions depend heavily on reach and frequency analysis. New brands typically prioritize reach to build initial awareness, while established brands may focus on frequency to reinforce messaging among existing customers. The optimal balance varies by product category, with complex purchases requiring higher frequency than impulse buys.
Media Mix Strategy
Media mix decisions rely on each channel’s reach and frequency characteristics. Television excels at building reach quickly, while digital platforms offer precise frequency capping and sequential messaging capabilities. Social media provides cost-effective reach among specific demographics, though frequency management becomes crucial to prevent user irritation.
Competitive Intelligence
Competitive analysis through reach and frequency benchmarking reveals market positioning opportunities. Brands can identify gaps where competitors under-invest or over-saturate audiences, allowing strategic differentiation through alternative reach and frequency approaches.

FAQ
What’s the difference between reach and frequency vs. impressions?
Reach counts unique individuals exposed to advertisements, while impressions count total advertisement views regardless of person. A campaign with 1,000 reach and 3.0 frequency generates 3,000 impressions. Frequency represents the average relationship between total impressions and unique reach.
How do you calculate effective reach and frequency?
Effective reach measures the percentage of target audience receiving optimal message exposure, typically defined as 3+ or 5+ frequency levels. Calculate by determining what frequency threshold drives desired response, then measuring how many unique individuals exceed that threshold within the campaign period.
What’s optimal frequency for different campaign objectives?
Brand awareness campaigns typically require 3-5 average frequency, while direct response campaigns need 6-8 exposures to drive conversions. Complex B2B purchases may require 10+ touchpoints, while simple retail promotions work effectively with 2-3 exposures. Creative quality and competitive intensity also influence optimal frequency levels.
Should marketers prioritize reach or frequency?
Campaign objectives determine priority. New product launches and brand building favor reach maximization to create broad awareness. Conversion-focused campaigns and competitive markets benefit from higher frequency to overcome message clutter and drive action. Budget constraints often force trade-offs between broader reach and deeper frequency.
