Understanding Media Markets
How markets, demographics, reach metrics, and audience data work on Tap.
Overview#
Media markets are the geographic building blocks of advertising on Tap. Every campaign you plan targets one or more markets, and understanding how they work helps you make smarter decisions about where to spend your budget.
This guide explains what markets are, how audience demographics factor in, what reach and frequency metrics mean, and how Tap uses all of this data to power your campaign planning.
What is a Market on Tap?#
A market on Tap represents a defined geographic region where media platforms operate and audiences are measured. In the United States, these align closely with Designated Market Areas (DMAs) — the standard geographic divisions used by the TV and radio industries to define media markets.
Each market on Tap includes:
- Geographic boundaries — The cities, counties, and regions that make up the market
- Population data — Total households and individuals within the market
- Available inventory — The radio stations, TV networks, podcasts, digital news outlets, and other media platforms that serve the market
- Audience demographics — Breakdowns by age, gender, income, and interests for the market's population
Examples of Markets#
| Market | Region | Households | Top Media Types |
|---|---|---|---|
| New York | NY, NJ, CT | 7.4M | TV, Radio, Digital, Podcast |
| Los Angeles | Southern CA | 5.8M | TV, Radio, Digital, Podcast |
| Chicago | Northern IL, NW IN | 3.5M | TV, Radio, Digital |
| Houston | SE Texas | 2.5M | TV, Radio, Digital |
| Phoenix | Central AZ | 2.0M | TV, Radio, Digital |
| Portland | NW Oregon, SW WA | 1.2M | Radio, Podcast, Digital |
Markets range from major metropolitan areas with millions of households to smaller regional markets. Tap supports markets across the entire United States, giving you access to both national reach and hyper-local targeting.
How Audience Demographics Work#
Every market on Tap comes with detailed demographic data that describes the people living in that region. Tap combines data from multiple sources — including census data, survey panels, and publisher-reported metrics — to build a comprehensive picture of each market's audience.
Key Demographic Dimensions#
- Age — Population broken down by age brackets (e.g., 18-24, 25-34, 35-44, 45-54, 55-64, 65+)
- Gender — Male, female, and total population counts
- Household income — Income distribution across brackets (e.g., under $50K, $50K-$100K, $100K-$150K, $150K+)
- Education — Levels of educational attainment in the market
- Interests and behaviors — Aggregated data on consumer interests, purchasing habits, and media consumption patterns
How Demographics Connect to Platforms#
Each media platform on Tap also has its own audience profile. When you view a radio station, podcast, or TV network, you'll see:
- Audience composition — What percentage of the platform's audience falls into each demographic group
- Audience index — How the platform's audience compares to the market average (an index of 120 means the platform's audience is 20% more concentrated in that demographic than the general market)
- Estimated reach — How many unique individuals the platform reaches within each demographic segment
This lets you match your target audience against available platforms to find the best fit.
Understanding Reach and Frequency#
Reach and frequency are two of the most important metrics in media planning. Tap calculates both for every platform and campaign.
Reach#
Reach is the total number of unique individuals who will be exposed to your ad at least once during a campaign. It's expressed either as a raw number or as a percentage of the target population.
- Platform reach — The number of unique people a single platform delivers (e.g., a radio station with a weekly reach of 250,000 listeners)
- Campaign reach — The combined unduplicated audience across all platforms in your media plan
- Target reach — Reach within your specific target demographic, not just total population
Frequency#
Frequency is the average number of times each reached individual sees or hears your ad during the campaign period.
- Average frequency — Total impressions divided by total reach
- Effective frequency — The minimum number of exposures needed for your message to make an impact (industry standard is typically 3+)
- Frequency distribution — A breakdown showing what percentage of your audience was reached 1 time, 2 times, 3+ times, etc.
The Reach-Frequency Tradeoff#
There's a natural tension between reach and frequency:
- Broader reach means exposing more people to your message, but each person may see it fewer times
- Higher frequency means your message is reinforced through repetition, but you're reaching fewer total people
Tap's AI planner helps you find the right balance based on your campaign goals. Brand awareness campaigns typically favor reach, while direct response campaigns may benefit from higher frequency.
Tap's AI uses your market data, audience profiles, and campaign goals to automatically optimize the balance between reach and frequency. You can also set manual targets if you have specific requirements.
Reading Audience Data Reports#
Tap provides audience data reports at the market, platform, and campaign level. Here's how to interpret them.
Market-Level Reports#
Market reports give you a bird's-eye view of a geographic region:
- Market summary — Total population, households, and media landscape overview
- Demographic breakdown — Charts showing age, gender, income, and interest distributions
- Platform inventory — All available media platforms in the market, with audience size and type
- Competitive landscape — Aggregated advertising activity in the market (where available)
To access a market report, navigate to Markets from the sidebar and select any market.
Platform-Level Reports#
Platform reports drill down into a specific media property:
- Audience size — Weekly or monthly unique listeners/viewers/visitors
- Audience composition — Demographic breakdown of the platform's audience
- Daypart analysis — How audience size varies by time of day (for broadcast media)
- Rate card — Available ad formats and pricing
- Audience trend — Historical audience data showing growth or decline over time
Campaign-Level Reports#
Once a campaign is running, Tap generates campaign reports that include:
- Delivery metrics — Impressions delivered, spots aired, or ads served
- Reach estimates — Projected unique audience reached across all platforms
- Frequency analysis — Average and effective frequency achieved
- Budget pacing — How spending tracks against your budget over time
- Performance by market — Breakdowns for each market in multi-market campaigns
How Tap Uses Market Data for Campaign Planning#
Tap's AI planner uses market data at every stage of campaign planning. Here's what happens behind the scenes.
Platform Selection#
When you define your target audience and select markets, Tap's AI:
- Identifies all available platforms in your selected markets
- Scores each platform based on audience overlap with your target demographic
- Ranks platforms by cost efficiency (cost per thousand target impressions, or target CPM)
- Recommends a media mix that maximizes reach within your budget
Budget Allocation#
For multi-market campaigns, Tap distributes your budget across markets based on:
- Market size — Larger markets receive proportionally more budget
- Target audience concentration — Markets with higher concentrations of your target demographic are prioritized
- Media costs — Adjustments are made for markets where media rates are higher or lower than average
- Campaign goals — Reach-focused campaigns spread budget more evenly; frequency-focused campaigns concentrate spending
Ongoing Optimization#
As your campaign runs, Tap monitors performance and may suggest adjustments:
- Shifting budget from underperforming markets to stronger ones
- Adding platforms that reach underserved audience segments
- Adjusting frequency caps to avoid oversaturation
You don't need to be a media planning expert to use Tap effectively. The AI handles the heavy lifting — but understanding these concepts helps you evaluate recommendations and make informed decisions.
Choosing the Right Markets#
Selecting markets is one of the most impactful decisions in campaign planning. Here are strategies for different scenarios:
Local Campaigns#
If you serve a specific city or region, focus on the single DMA that covers your area. This concentrates your budget for maximum frequency and impact. For example, a restaurant chain in Phoenix would target only the Phoenix DMA rather than spreading budget across the state.
Regional Campaigns#
For brands that serve multiple cities or a broader region, select a cluster of adjacent markets. Tap lets you group markets together and allocate budget proportionally based on population or opportunity. A Pacific Northwest retailer might target Portland, Seattle, and Eugene as a regional cluster.
National Campaigns#
National campaigns typically target the top 25-50 DMAs to cover the majority of the US population. Tap's AI can recommend the optimal set of markets based on your target audience and budget. You don't need to select all 210 DMAs — the top 25 markets cover roughly 55% of US households.
More markets means your budget is spread thinner. If you're working with a limited budget, it's better to dominate a few key markets than to have minimal presence across many. Tap's planner will warn you if your budget-to-market ratio is too low for effective reach.
Comparing Markets Side by Side#
Tap's market comparison view lets you evaluate multiple markets at once. You can compare:
- Total audience size and demographic composition
- Number of available platforms by media type
- Average media costs (CPM) across channels
- Your target audience concentration relative to the general population
This helps you prioritize markets where your target audience is most concentrated and media costs are most efficient.
