OOH Advertising
Three seconds. One idea. Impossible to miss.
OOH (out-of-home) advertising is any advertising people see outside their homes — hoardings, billboards, bus shelters, metro and railway stations, airports, malls, cinemas and digital screens. Nebula Brand Labs creates OOH campaigns with ideas big enough to be noticed at 60 km/h and simple enough to be understood in a single glance.
About the service
In a city like Mumbai, people spend hours every day on the road, in trains and in transit. Outdoor media reaches them in those moments — repeatedly, unavoidably and at scale. It's one of the few media that can't be skipped, blocked or scrolled past.
But OOH is also unforgiving. A hoarding with too many words, a weak visual or a cluttered layout is simply invisible. We design outdoor campaigns around a single, powerful idea, then adapt it intelligently for every site, size and format.

Frequently asked questions
What is OOH advertising?
OOH stands for out-of-home. It covers any ad seen outside the home: hoardings and billboards, bus shelters, metro and railway stations, airports, malls, cinemas, and digital screens. It's ideal for building mass awareness and local visibility.
How much does a hoarding cost in Mumbai?
Hoarding costs vary widely depending on location, size, visibility, traffic and duration. A prime site on the Western Express Highway costs very differently from a smaller site in a local market. We'll create a plan with options that fit your budget and objectives.
What makes a good hoarding design?
One idea, one strong visual, very few words — ideally seven or fewer — and a clear brand mark. People see hoardings from a distance and often while moving, so the message must be understood in about three seconds. Bold colours and high contrast help too.
Do you handle media booking and installation?
We work with trusted OOH media partners to plan sites, negotiate rates, book media, print and install. We share installation photos and monitoring reports so you know your campaign is live and visible.
What is digital OOH, and is it worth it?
Digital OOH uses digital screens at airports, malls, metro stations and roadsides. It allows motion, multiple creatives and time-based messaging — for example, different ads for morning and evening. It's great for brands that want flexibility and a premium feel.
How do you measure the impact of an OOH campaign?
OOH is harder to track than digital, but it can be measured. We use branded search lift, dedicated phone numbers, QR codes, website traffic from target areas, footfall at sites or stores, and brand recall surveys.
How long should an OOH campaign run?
Most campaigns run for at least two to four weeks so enough people see the ad multiple times. Launches often use a short, high-intensity burst, while always-on brands rotate sites over months.
Can OOH work for a smaller budget?
Yes. Instead of large hoardings, smaller budgets can target specific neighbourhoods with bus shelters, society branding, auto branding or local digital screens. Smart site selection often matters more than size.
