An ad is only as good as the words contained within the ad itself. If you don’t know how to write good advert, then either get someone to write it for you or learn how to do it yourself. The latter is your best bet, first it will be free and you will get better with every attempt, like the saying goes ‘practice makes perfect’. You will have a limited amount of space to work with depending on which classified  website you decided to work with, so your job is to entice the potential buyer as quickly and succinctly as possible. How do you do that?

What should your advert say?
It should adequately describe what it is your small business has to offer (product or service wise), and why a potential buyer will benefit. Have an eye grabbing headline and then follow on within your adverts body text. Remember, people want to know not only what you’re providing, but how it fills some need they have. So you need to tell them. Don’t use much fancy language or big words. DO use urgent language, such as “Hurry” and “Act Now”. Using enhancing words in your descriptions like, “Stunning” and “Amazing” can really grab the viewer’s attention. Be bold, be brave.

Which do you like better? Getting the idea now... There are many ways to build your advert. There are plenty of resources on the Web to get you through this process. You can always do some research via search engines to see what types of ads people run for the kinds of products or services your small business offer, jot down the ones you like and the ones you don’t like and why you don’t like them.

Below are some steps for creating adverts that are simple yet effective:
1) Seize your reader’s attention. You do this by having a good headline. Keep it short and to the point it is an advert.

2) Capture your reader's interest. What makes your advert interesting? Are you providing an interesting product or service, and if so, why is it interesting?

3) Create a need and want in your reader's mind. You want your targeted reader to drool over what it is you have to offer. You need to describe your service or product powerfully and succinctly, so you can create the desire. Even if your reader doesn’t need or want what you are providing, a really good written advert should make them want it regardless.

4) You are filling a need. Whenever you can’t create a need, attempt to make certain you're filling an existing need your potential buyer has.

5) Call your readers to action. If you don’t ask for the sale, you will not get it; it's as simple as that. This is the most common mistake people make; don't assume they know what to do because they don't. You have to ASK for the sale.

7) Remember to give your readers with your contact details. Don’t ask for the sale and then forget to leave them a way to get into contact with you. Irrespective of how good your advert is, no contact details mean NO sale.

Last, but not least, when people to answer to your advert, make sure you follow-up with them very quickly, within 24-hours if possible. The longer you delay, the more likely the chance they'll go somewhere else to get what they need.
