Billboard vs digital billboard advertising: is a rotating slot worth it?

A printed hoarding is yours for every minute of the month you have paid for. A digital screen at the same junction gives you one slot inside a loop that also carries seven or eight other brands. You are present for a few seconds at a time and absent the rest. That is the whole comparison. Before you look at either price, work out what share of the screen's time you are being sold. The two numbers on the quotations are not measuring the same thing.

Share of place against share of time

A printed site is a piece of property. It is above that junction at eight in the morning, at the six o'clock jam, at midnight, on the day of the festival and on the day your competitor launches. Nobody else is on it.

A digital site is a time-share. Your ten seconds appear every eighty or hundred seconds, and in between the screen belongs to a bank, a builder and a jewellery brand. For a car waiting at a long signal, that rotation is fine: the driver sits through the loop twice. For a car that sails through at forty kilometres an hour, your slot may simply not be on the screen at that moment.

So the honest question is not which technology is better. It is whether the traffic at that site stops long enough for a rotation to reach it.

What you own in each case

The landmark effect belongs to the printed board

People give directions using hoardings. Turn left after the board with the sari shop on it. That only happens to a site that never changes. It is the quiet dividend of buying the same printed board for a year rather than a screen for a quarter.

Suppose you want to be the name people say when somebody asks where to buy something in that area. The permanent site is doing a different job there from any amount of rotation. The screen gives you reach and variety. The board gives you a place in how people describe the neighbourhood.

What the screen is genuinely better at

Time of day. A restaurant can buy the eleven to two band and the seven to ten band and pay nothing for the hours when nobody is deciding where to eat. No printed site can do that.

Short campaigns with a date. A three-day exhibition, a match-day offer, an inauguration on Sunday, a limited stock clearance. The message can even count down.

Changing your mind. If the price changes or the offer fails, the copy is replaced the same day at no printing cost. That is worth a great deal to anyone still learning what their market responds to.

Night presence without a lighting bill. Illumination on a printed site is a separate charge and a frequent dispute. A screen is bright by definition.

What moves the price on each

For a printed site: the corridor and its traffic count, the size and height, whether it is lit, and what obstructs the view. Direction of travel matters as much as any of those, because a board facing the morning flow into the city is a different product from the one across the road. Then there is vacancy. A board that has been empty for two months is negotiable in a way that a board on a waiting list is not.

For a screen: the loop length and how many advertisers share it, the length of your slot, which dayparts you buy, the size and resolution, and the junction itself. Ask for loop length in writing. A screen with a hundred-and-twenty-second loop and twelve advertisers is a different product from one with an eighty-second loop and eight, at the same price.

When each is the wrong buy

A printed hoarding is wrong when your message has a short life or keeps changing. Paying to print and mount a two-week offer wastes most of the production cost, and a board that still shows last month's price does active damage.

It is also wrong when the site is cheap for a reason. A low rate on a stretch of Mysore Road usually means one of two things. The board faces away from the morning flow into the city, or a flyover has cut the sightline since the photograph was taken.

A digital screen is wrong when you need to own a place rather than appear in it. Wrong again where the traffic moves quickly past, or where your category needs long consideration rather than a burst. And wrong wherever the operator cannot tell you the loop length or show a play report. Screens change hands. An unverified one is a receipt, not a campaign.

The artwork is not the same artwork

A printed board is read in about two seconds by somebody who is driving. Six words, the name large enough to read from the far lane, one reason, and one way to respond. Anything else is decoration you are paying rent on.

A screen tempts people into motion, and motion is where outdoor money dies. A driver catches one frame, so a sequence that reveals the offer in the fourth second reveals it to nobody. Build the ad as one frame that works alone, and let the movement be small. Local rules on brightness and animation differ by city and by site, so ask the operator what the permission actually allows before the artwork is made.

What to buy for your own road

You have one location, on a road your customers already use. Then a printed site on that road is the stronger buy: a quarter, one clear message, one way to respond. Recognition there is worth more than reach elsewhere.

If your offer changes, or your customers come at particular hours, or you want to test outdoor before committing a quarter, buy a digital slot for a fortnight. Put a distinct phone number on it. Then see what the call log does between the hours you bought.

They also combine well, and that is how most well-planned outdoor money gets spent. The printed board near your own catchment holds the name all year. The screens carry whatever is happening this month.
