With all types of advertising whether you have a basic or a fanastically setout leaflet, you will have peaks and troughs on the response of work that they generate.
For instance I have posted 100 leaflets and had over 20 calls,
I then dropped another 2000 in the same area and the response was zero.
I have also canvassed an estate, on every house it was "No Thank You"
I then went into a cul-de-sac with only 30 or so houses and got 12 jobs
I have used many many diferent types of leaflets over the years and I have come to the conclusion thats its a numbers game, the more leaflets you get out in the public domain the more work you will get.
The best type of leaflet that I find work well is the one that is professionally printed, is short on words and to the point and has a picture.
The reason why is because when someone gets a leaflet though their door, their first reaction is to give it a quick look then screw it up and bin it, but if you have a picture of your services this will draw their attention to your leaflet for them to read it, the message you want to impart should be short and too the point, no one wants to be reading a book when a few words can say the same message and make sure your leaflet is printed professionally because this says a lot about your company.
But if you want to really increase your customer base then the only way to do this is, you need to promote your business at every opportunity, door knock and leaflet all the time, get your excisting customers to reccommend you to their neighbours, friends and family.
But remember one thing, to build a really sucessfull business, takes time, so don't let it stress you out.
