Without metrics, you are trapped by that famous conundrum. "Half of the money is spend on advertising is completely wasted. I just have no idea which half," John Wanamaker said. Well, in the age of technology that doesn’t have to be the case. Metrics measurement and monitoring is easiest to enact with web-based advertising, but just as possible with text message SME marketing. We look at how!

Reply mechanisms for metrics
If you want to measure the success of your campaign, it is essential that you design it so that you have a trackable method of knowing which people take action after they read your ad. In text message SME marketing, this usually means that a reply mechanism is included.
You'll need to find a program that allows people to send texts, while the network charge for them goes to you, however. This is especially true in some instances. Will your audience be willing to spend 20 cents simply to learn more about something? Will they be willing to spend 20 cents to have a chance at winning an iPod? Will they be willing to spend 20 cents to give their opinion on something? Put yourself in their shoes (try to be as unbiased as possible).
Different reply numbers for different campaigns
You can also get a sense of how your promotions are working across different demographics by having different reply numbers for different advertisements. For example:
- Have people reply-text to 11100 in the ad you place in Cleo magazine, and reply-text to 11104 to the ad you place in the New York Times.
- When you send out your messages, group them by demographics. When you know a customer's sex, age, location and so on, send a grouped text message asking them to reply to a specific number.
This way you get a feel for how different groups respond to certain promotions.
