Route (OOH Audience Measurement)

Route: Measuring Out-of-Home Advertising Effectiveness

Route is the industry-standard audience measurement currency for Out-of-Home (OOH) advertising in the UK. Developed by the Outdoor Advertising Association (OAA) and IPSOS, Route provides reliable data on who sees your OOH campaigns, when they see them, and how often. Understanding Route is essential for media buyers looking to justify OOH spend and optimise campaign performance.

Why Route Matters for Your OOH Strategy

Unlike digital channels where tracking is straightforward, OOH requires a standardised measurement approach. Route solves this by providing:

• Comparable audience data across all OOH formats (billboards, transit, roadside, retail)
• Demographic breakdowns to target specific audiences
• Frequency and reach metrics to plan effective campaigns
• Cross-media planning capabilities to integrate OOH with other channels

For a UK marketing professional, Route data enables you to speak the same language as media owners, justify investment to stakeholders, and make confident media buying decisions.

Understanding Route's Key Metrics

Visibility and Impacts

Route distinguishes between visibility and impacts:

• Visibility measures whether someone could physically see an advertisement
• Impacts represent actual exposures – when a person has the opportunity to see a poster or campaign

For example, a billboard on the M25 near Junction 10 might have high visibility to commuters, but actual impacts depend on traffic flow, time of day, and sightlines.

Target Audience Profiles

Route provides audience data segmented by:

• Age groups (16-24, 25-34, 35-44, 45-54, 55-64, 65+)
• Gender
• Socio-economic classifications (ABC1, C2DE)
• Vehicle occupancy (for transit-based OOH)
• Time of day and day of week variations

When planning a campaign for a premium coffee brand targeting affluent professionals, you'd use Route data to identify high-traffic locations with the right demographic composition during morning commute hours.

Planning with Route Data: A Step-by-Step Approach

Step 1: Define Your Campaign Objectives

Start by clarifying what you want to achieve. Are you building brand awareness, driving footfall to retail locations, or supporting a product launch? Your objective determines which Route metrics matter most.

Example: If launching a new gym membership offer, your primary goal is reach among health-conscious 25-45 year-olds in specific postcode areas. You'd prioritise locations near residential areas and busy commercial centres.

Step 2: Identify Target Locations Using Route Data

Route allows you to search for poster sites and transport locations with specific audience characteristics. The process typically involves:

1. Logging into the Route platform through your media buying software or directly
2. Filtering by geography (postcode, town, region)
3. Selecting format (6-sheet, 48-sheet, transit, retail)
4. Reviewing audience composition and daily/weekly traffic patterns
5. Comparing reach and frequency across potential sites

For a national campaign, you might identify secondary markets with strong audience concentrations but lower costs than premium London locations.

Step 3: Calculate Reach and Frequency

Route provides weekly and monthly reach figures – the percentage of your target audience exposed to your campaign at least once. It also shows frequency distribution (how many times the average viewer sees your ad).

As a rule of thumb: - Reach of 60%+ indicates good market coverage - Frequency of 3-5 provides adequate message reinforcement - Reach of 80%+ with frequency 5+ suggests a strong, saturated campaign

Practical tip: A three-month campaign with 70% reach and frequency 4-5 among your target demographic typically requires a good-quality, high-traffic site or a selection of complementary secondary locations.

Step 4: Budget Allocation Across Formats

Route data helps you decide how to split budget between format types:

• 48-sheet posters deliver high reach in specific geographic areas
• 6-sheet posters work well for hyperlocal targeting near point-of-sale
• Transport advertising (buses, trains, stations) captures commuter and leisure audiences
• Retail reaches shoppers at decision-making moments

A regional retailer might allocate 60% to 48-sheets in major towns, 30% to transit near transport hubs, and 10% to retail within stores.

Optimising Your Campaign with Route Insights

Monitor Performance Against Projections

After launch, compare actual traffic counts against Route's projected impacts. Route figures are based on historical traffic data and census information, but real-world variations occur. If a location underperforms, you can:

• Request traffic data validation from the media owner
• Reallocate budget to better-performing sites
• Adjust creative messaging if audience composition differs from expectations

Use Route for Cross-Media Planning

Route data integrates with other measurement systems. Many media agencies use Route OOH figures alongside digital metrics and TV/radio data to calculate total campaign reach and frequency across all channels. This gives stakeholders confidence that OOH investment isn't duplicating digital spend but reaching additional audiences.

Example: A financial services campaign might use Route to target commuters at major train stations (reaching high-income professionals) while digital targets the same demographic online during evenings – ensuring cross-channel frequency without waste.

Benchmark Against Previous Campaigns

Keep records of Route projections versus outcomes. Over time, you'll develop benchmarks for different location types, seasonal variations, and format effectiveness. A high street location might consistently deliver 15-20% better impacts during Q4, informing future festive campaign planning.

Common Route Pitfalls and Solutions

Pitfall 1: Over-relying on projected impacts Route provides best estimates, but actual traffic varies seasonally, with weather, and during major events. Build in contingency and monitor real-world performance.

Pitfall 2: Choosing locations solely on metrics A location might show strong demographics on Route but have poor sightlines or visual clutter from other posters. Always visit high-value locations in person before committing significant budget.

Pitfall 3: Ignoring frequency distribution Route shows average frequency, but distribution matters. High variation (some viewers see your ad once, others ten times) is less efficient than consistent frequency. Look at the actual distribution curve, not just the average.

Getting Started with Route

1. Access: Work with your media agency or media owner to access Route data
2. Training: Most platforms offer webinars or guides; invest 1-2 hours learning your specific interface
3. Reporting: Agree with stakeholders which Route metrics you'll report (reach, frequency, demographic coverage)
4. Integration: Link Route data to your broader media planning and reporting processes

Route measurement might seem complex initially, but it's the foundation of professional OOH buying in the UK. Mastering it positions you as a credible media strategist.
