Billboard advertising in Bangkok: how to choose a site and what it really costs

Pick the road your customers drive

The busiest road isn't always the right one. Ask who drives past: commuters into the city in the morning are a different audience from traffic heading out in the evening. A board on your buyers' daily route does more than a famous location they never pass.

Work out the cost per 1,000 views

A quick estimate you can do with any site's traffic count:

daily traffic × 1.45 people per vehicle × 0.5 who look × 30 days = views a month
monthly price ÷ monthly views × 1,000 = cost per 1,000 views

That number lets you compare a billboard fairly with what you pay per 1,000 views on Facebook or YouTube. Ask every billboard owner for the daily traffic before you book; if they can't give it, you can't judge the price.

Say one thing

A driver has a few seconds. One message, under seven words, plus your logo. Give one next step: a LINE ID, a direction ("next left") or an offer with a date.

Stay at least three months

People need to pass a board many times before it sticks. One board on the same road for three months or more beats three boards for a month each.

National networks or corridor owners?

Thailand's large out-of-home networks run thousands of faces nationwide, including transit and digital screens, and suit national campaigns. Owner-operators with fewer sites suit campaigns aimed at one area: a project launch, a showroom or a mall opening. Whoever you book, ask for the size, the daily traffic and who passes, per site.

Our boards

Thai Prasith Signtech owns 27 billboard sites on six corridors across Greater Bangkok and the Eastern Seaboard. Each site's size, area, daily traffic range, audience and best-fit categories are published on our billboards page. We print, install and check the board ourselves, and on our boards the permits, inspections and sign tax are ours. Booked boards go up within 7 days.
