What are some ideas for planning out a successful advertising campaign for a small business?

The first thing to do is to make your advertisement "easy on the eye" for your target group. If you are advertising for home-delivered groceries, then you should probably try to reach the people who have a stressful workday. You should also think about who your bigger rival companies are, what you could offer that the bigger ones don't. You could also get some free ideas from friends and family that may be of help if they are the kind of group your business are targeting.
