It's not what you say, but how you say it, that contributes towards a successful campaign. Be aware that your customers come first; after all, your business would not exist without them, so therefore they need to be the main focus for your campaign. This means you need to turn your mindset around to accommodate the fact that your business comes way down the pecking order of importance.
Each element of your message needs to be carefully planned, placed and executed. The first thing at the top should not be your logo and company name. Even though most leaflets and adverts blare theirs out from this position, this only works for worldwide recognised businesses; otherwise the reader's reaction is 'who?' or 'so what?'.
The main key element is the headline, which should be designed to attract attention. Begin your campaign with a statement or question that stimulates a positive response to your customers' pain or problem. You should have done adequate market research to find this out, so position yourself inside your customers' head and start to think like them. Work with something that will result in the reader saying 'yes'.
The subhead should provide the resolve or solution to the headline, and there you can subtly drop in the name of your company. I mean subtly, as the solution should always come first. The result should be to increase the readers' empathy towards what you are offering.
Next highlight your benefits in bullet points. Here most businesses happily list their features, but remember since you are focusing on your customers, turn these features around to their point of view, so that they become customer benefits. Take out all the 'we' and 'our' and substitute them with 'you' and 'yours' to achieve this.
Why use bullet points? Readers find it easier to scan or quick read through a list than to trawl through a dense paragraph. In this fast moving 21st century, bombarded with stimuli from every direction, people don't have the time or inclination to read everything. A list containing concise, focused and relevant points is more likely to be absorbed.
If you don't ask, you don't get. How many campaigns forget to include a call to action? The remainder of your leaflet could contain all the right ingredients, but if you don't ask your readers to do something, even to tell them to call you for more information, then what is the point? And by making this time-dependent you are more likely to stimulate a response, otherwise, even if they have the best intentions towards your campaign, there is no stimulus to demand a quick reaction and your leaflet could get forgotten.
And last but not least, make sure your contact details are large, clear and easily accessible. If your telephone number doesn't jump out to hit them between the eyes, your landing page web-address is not clearly visible, or your email is hidden amongst other text, you will not encourage your customers to make contact. And no customer contact means no sales.
