The key to writing a successful ad is knowing your audience and understanding what will motivate them to buy. You should already know what makes your target market tick before you even consider writing an advertisement. You also need to be clear on what you can offer them and what you are trying to achieve.
There's nothing to stop you writing the advertisement yourself. However, if you are struggling to come up with the right words, you could hire a freelance copywriter or an advertising agency.
Clarity is key. Focus on a single, clear message and use the headline, an illustration or both to grab the reader's attention.
The simple approach is usually best. A successful headline might highlight the key benefit your product offers, or arouse the interest of your target audience. Look through the ads in the publications you are planning to advertise in to give you a good idea of what works and what doesn't.
Any online advertising copy must include the keywords and phrases that people are most likely to use when searching for a business like yours.
Once you've got the reader's attention, the body copy adds more information. Again the key is to concentrate on what your target reader is interested in and what you are trying to achieve.
Big brands sometimes produce ads with no body copy at all: the illustration along with their brand name is enough to convey the image they are after. At the other end of the scale, ads in specialist magazines may include more extensive details for the enthusiast.
Straightforward, punchy writing works best. Keep sentences short.
If in doubt, leave it out. Don't be afraid of having plenty of white space in your advertisement. But do make sure you have given the reader the information they need to take the next step. It's essential to make it easy for them to do what you want them to do. So make sure you include your contact details, and consider encouraging them to act by including a deadline.
Once you've drafted your ad, leave it overnight before you read it through. If you can, get the ad properly laid out before you check it.
Then put yourself in the shoes of one of your target customers and have a look at the ad:
Finally, test the ad with customers and suppliers before you use it in the media.
