Splitting an ad budget: the 70-20-10 rule
Seventy per cent on what works, twenty on scaling, ten on experiments. The rule is old, simple, and violated in almost every account.
Strategy & Craft
Customers do not buy specifications. They buy the change the specification produces, and most advertising never mentions it.

Most product advertising lists what a thing is. Effective advertising describes what changes for the person who has it.
Take any feature and ask "so what" until the answer stops being about the product.
The fourth line is the advertising. The first line is the specification sheet.
Benefits create interest, features close the deal. Someone already convinced needs evidence that the promise is real.
The order matters: benefit in the headline, proof in the body, specification in the detail section. Reverse it and the reader never reaches the part that would have persuaded them.
| Category | The customer gets | Works best for |
|---|---|---|
| Money | lower cost, higher return | investments, energy, B2B |
| Time | faster, less effort | services, software, trades |
| Risk | fewer things going wrong | insurance, legal, medical |
| Standing | being seen differently | premium goods, image services |
Most offers carry more than one. Lead with the one your specific audience actually feels. A landlord buys the money benefit; an owner-occupier often buys the comfort.
The strongest benefit statements are quoted, not written. Ask five customers one question: what is different now compared with before?
Their answers arrive in plain language and name things the internal team overlooked. A cleaning company discovered its customers valued not the cleanliness but that they no longer had to manage the previous supplier's staff turnover. That became the campaign.
A benefit without a number is a claim. A benefit with a number is an argument.
The third version is harder to write because it requires you to know your own results. That is precisely why competitors do not write it.
Strike every sentence beginning "We are" or "We offer". Rewrite each as "You get" or "You no longer have to". The exercise takes twenty minutes and rewrites most brochures usefully.
They are, as proof, once the benefit has been established. They convince the person who is already interested.
Ask "and that means what for the customer" three times in a row until the answer changes.
