OOH Planning and Buying — How to plan and execute an outdoor advertising campaign

A well-planned OOH campaign follows a structured process. The 8 steps below apply to both global markets and India specifically.

Step 1: Define the objective

OOH objectives fall into three buckets: Brand awareness (I want more people to know I exist), Location reminder (I want people near my store/branch to think of me), Campaign amplification (I am running TV/radio/digital and want OOH to multiply the effect). Each objective drives different site selection, creative approach, and measurement approach.

Step 2: Define the target audience

For OOH, audience targeting is geographic and behavioural — not demographic in the digital sense. You target people who travel specific routes, visit specific locations, or live in specific areas. Define: geography (city, district, corridor), route behaviour (commute route, shopping route), dwell environment (drive-by at speed vs pedestrian vs waiting at a platform).

Step 3: Set the budget and duration

Minimum effective outdoor campaign: 4 weeks (less does not allow sufficient repetition for memory encoding). For a brand awareness objective: 8–12 weeks. For a launch or event: a concentrated 2-week burst is acceptable if combined with other media.

Step 4: Site selection

Get a site list from the media owner or agency. Evaluate: DEC (Daily Effective Circulation), sightline (distance from which the board is visible — minimum 50m for a 40×20 ft board), traffic direction (is the board visible to traffic going toward your catchment area?), competition clutter (how many other boards within 200m?), and creative context (does the neighbourhood align with brand positioning?).

Step 5: Site inspection (recce)

Always inspect shortlisted sites in person. Check for: obstruction by trees, bridges, or buildings (seasonal variation — trees with leaves in monsoon may block a board invisible on a dry January recce photo), new construction, angle relative to traffic flow, and visibility at drive speed. A 10-minute site visit eliminates the most common OOH planning failures.

An OOH brief to an outdoor agency or media owner should contain:

• Campaign objective: one sentence — what do you want people to do, think, or feel?
• Target audience: geography, route behaviour, dwell environment
• Budget: total available, media-only or including production
• Duration: start date, end date, flexibility
• Format preference: large hoardings, transit, DOOH, mix
• Creative constraints: existing creative assets, size requirements, whether animation is needed (DOOH)
• Measurement requirement: DEC minimum per site, total GRP target, attribution method
• Legal requirement: IOAA member sites only, licence documentation required (India)

A 1-page brief with these 8 elements is sufficient for any OOH agency to respond with a proposal. Longer briefs that include the full brand strategy are useful context but should not replace the 8 essentials.

OOH rates in India are almost always negotiable. Standard negotiation dynamics:

• Volume discounts: buying multiple boards from the same owner typically attracts 10–25% discount off rate card
• Duration discounts: committing to 3 months typically gets better rates than 1 month at a time
• Off-peak discounts: January–March is typically the slowest OOH season in India (post-festive, pre-summer). Rates are negotiable. June–August (monsoon) is also soft for many categories.
• Package deals: some media owners offer a "metro package" (multiple boards across a city) at a package rate lower than the sum of individual board rates
• Production inclusion: for flex hoardings, printing and installation is sometimes included in the rate or offered at cost. For DOOH, creative upload is usually included.

Always get the rate in writing on the Release Order before signing the Purchase Order. Verbal rate agreements are not enforceable under the IOAA-AAAI SOP.

Post-campaign measurement options for OOH (from most to least rigorous):

1. Brand tracking study: survey of brand awareness, recall, and purchase intent before and after the campaign. Expensive but the gold standard for measuring brand-building effect.
2. Mobile attribution: using a partner like Geopath (US) or an India mobile measurement provider to track device exposures near your boards and correlate with in-app behaviour, store visits, or digital conversions.
3. WhatsApp inbound tracking: measure how many WhatsApp conversations were initiated during the campaign period versus a control period. Tag different boards with different keywords to isolate which locations drove most response.
4. Store traffic / footfall: for retail, track store visit uplift during campaign period vs equivalent non-campaign period. Control for other variables (weather, promotions, competitor activity).
5. Campaign period sales uplift: the bluntest measurement — total sales during campaign vs equivalent period. Confounded by many variables but easy to calculate.
