We’ve all seen them: Those square barcodes that have been popping up everywhere from cereal boxes to business cards. Many of us, however, don’t know what the strange-looking images are—much less how we might want to use them in our marketing.

The barcodes, called QR (Quick Response) codes, work something like the barcodes found in supermarkets or other stores: When scanned, they provide information. A QR code can support up to nine different types of data including, contact info, URL link, calendar event, geographic location, etc.

In order to read the code, you will need to “scan” it by taking a photo with a smartphone camera (Keep in mind, you have to download an application to read the codes). Once read by a smartphone, QR codes direct potential clients to a “landing page” on the internet, where they will be able to access what they were sent for, whether it is information about trends in your practice area, event details, contact information, etc.

If you’re thinking about incorporating QR codes into your marketing efforts, there are a few points to consider:

  • First, what will you provide using the code? A video about a recent court decision that impacts your clients? Contact information?  A discount?  How will your offer improve your potential clients’ lives? You need to provide something of value to keep them engaged.
  • You should deploy a “call to action” with your QR code—just a few words near the code to entice people to scan it. For example, “Scan this code for a free gift,” yields a higher scan rate than, “Scan this code.”
  • Think about design and usability. Color, for instance, makes a code look more approachable than the traditional black and white. A common mistake when it comes to QR codes is to direct people to your regular website. Aside from the fact that many websites don’t load very well on cell phones, your standard website doesn’t provide any added value to a potential client. He or she could have easily accessed your website without the code.
  • Once you have your QR code marketing campaign in place, it is important to track the results. The most meaningful way to do this is to track not only the number of scans, but how much time visitors spent on the landing page. If the landing page is your Facebook page or Twitter account, you should record how many new fans/followers you received during your QR code campaign.

QR codes are here to stay, and will only be popping up in more places as time goes on. You can quickly and easily generate a code using sites such as Kaywa, Qurify and Delivr. QR code marketing can be quite successful—if, before embarking, you give thought to the factors involved in developing a high-quality campaign.
