11 Ways to Get Better Results from Doorhanging
Add a couponâ€â€at least one, even if it’s a regular-price offer or an invitation to join your Frequent Diners Club. Use heavy dotted lines around the edges to make your offer look like a coupon.
Add a time limit. An expiration date 5 to 7 days out usually draws well.
Hang on Thursdays, and on a payday week (the week of the 1st or 15th).
Target the right neighbors. If you deliver, track your orders on a map for a few weeks first to identify your hottest neighborhoods. That’s where you want to spend your money. (If you have a POS, you can do this in an hour: import your entire customer database into MapPoint to map your customers and look at demographics.)
Use an attention-getting headline, professional design, and mouth-watering copy.
Give them a reason. Tell them what makes your restaurant special, and what’s in it for them.
Include one or more special offers (something free, $2 off, a package deal) and a clear call to action.
Dine-in? Carryout? Add a simple map. If they know they can find you, they’ll be more likely to come.
Add a personal invitation with your signature to the design. Consider adding your photo, or a picture of a smiling employee.
Keep it up! Consider creating 2 or 3 different doorhangers with different offers. (You can usually get two pieces printed at 5,000 each for the same price as a 10,000 of a single design.) Response rates of 1 to 2% are pretty typical with doorhanging. These tips may help you improve on thatâ€â€but even so, it’s a numbers game. Make sure that you’re distributing enough doorhangers to cover your costs and bring in new customers you want.
Look for co-promotion opportunities to reduce your costs. Find another company to pay for the printing costs in exchange for a coupon on your doorhanger. Be creative.
