How to split a budget between digital and offline

There is no correct ratio, and anyone who gives you one without asking what you sell is quoting a number they read somewhere. The split falls out of four questions. Does anybody search for what you sell. How wide is the area you can actually serve. What would the smallest worthwhile offline buy swallow out of your year. And are you capturing demand that already exists, or creating demand that does not. Answer those four and the ratio writes itself.

Does anybody search for what you sell

This is the first fork, and it decides more than budget size does.

Check it rather than guess. Open the keyword planner for your category and your city, and look at whether the monthly volume is thousands or tens. A Bengaluru orthodontist has plenty of people searching. A manufacturer of a specialised gasket has almost none, and no amount of budget will create them.

The floor problem, which forces the split more than strategy does

Digital has no minimum. You can spend a small amount on search this week and stop on Friday. Every offline medium has a floor built into how it is sold. A hoarding comes as a display cycle plus printing and mounting. Cinema is sold in weeks, radio in a schedule of spots across a fortnight, a newspaper insert in a minimum drop by area.

So the real question is not what percentage you want offline. It is whether the smallest honest buy in the medium you want fits inside your year without taking the money the rest of the plan needs. If one hoarding cycle would take a third of your annual advertising budget, buy something else. Half a hoarding does not exist, and a hoarding for two weeks is money set on fire.

Capture and create are two different jobs

Demand capture is showing up when somebody has already decided to buy. Search, Maps, marketplace listings, retargeting. It is cheap per enquiry, it is measurable, and it has a hard ceiling: you cannot capture more demand than exists.

Demand creation is being remembered by somebody who was not looking. Hoardings, cinema, radio, newspaper, video, community events. It looks expensive per enquiry on paper. It is also what makes the capture cheaper later, because a person who knows your name clicks your result instead of the sponsored one above it.

Almost every business should fund capture completely before funding creation. Fill the bucket that has holes first. Working out where the ceiling sits and what to buy above it is media planning and buying.

How you know digital has run out

Money should move offline for a reason you can see, not because somebody called with an offer.

Look for three signs together. Your impression share on the searches that matter is already near the top, so there is nothing left to buy. Cost per enquiry has climbed for three months while the quality of those enquiries stayed the same. And the volume of searches for your category in your service area is flat, which the keyword tool will show you.

That combination means you have reached the end of the people who are looking. The next order has to come from somebody who was not, and that is what offline is for.

Three shapes, and which one you are

A single-outlet local business, a clinic, a salon, a showroom, puts most of the money into search, Maps and reviews. What is left goes into one offline format that stops at the same boundary as the catchment. Panels in the apartment societies its customers live in, an insert in the pincodes it delivers to, or a board on the road they drive daily. Nothing city-wide.

A city-wide consumer brand or a multi-outlet retailer needs a real offline block around its two selling seasons. The whole city has to know before the season starts, and digital alone cannot buy that in a fortnight. Outside those weeks it should sit mostly on always-on digital.

A B2B manufacturer or a professional firm should barely be here. Its buyers are a countable list. The money belongs in search, a site that answers technical questions, a marketplace presence and somebody making calls. The exception is where buyers physically gather: an exhibition, an industrial estate, a trade paper.

Fix a floor, then let the rest be contested

Protect the offline flight you have committed to for its full run, because stopping halfway pays for the setup and collects none of the effect. Protect the search budget on your own brand name and your core service, because that is the cheapest enquiry you will ever buy.

Everything above those two floors is contested money. Review it monthly, move it towards whatever produced enquiries, and write down the reason each time you move it. Combining offline and digital covers the tracking that makes those reasons visible.

The reasons a split gets decided badly

Last year's number, carried forward because nobody reopened it. A seller who called at the right moment with a site going vacant. The owner's own media habits, which is why businesses selling to twenty-five year olds keep buying the paper the owner reads at breakfast. And a round figure that felt balanced, which is how a small budget ends up split evenly across five channels and doing nothing anywhere.

What to do next

Take your annual figure and answer the four questions at the top of this page in writing, in one sentence each. Then price the smallest honest buy in the offline medium you were considering, including printing and mounting, and see what share of the year it takes. Most splits settle themselves at that point.
