If not, don't worry. Before my job at Ontraport I never had either. Even after working there for several months, they were spooky. They were quasi-mystical, like most computer technology, until I understood it.
Then I discovered they're just a fancy way to tell web addresses apart. Create them to track where people are coming from to visit your site. By adding a UTM variable you can tell which hyperlink gets the most traffic. It’s a marketing tool. It’s a bit like putting a label on a physical product, say refried beans. What’s inside the can isn’t all that different, no matter what the label says. Instead, the label is for the company as much as it is for you. The label lets the company know you bought their beans instead of someone else’s.
Oh, by the way, UTM stands for Urchin Tracking Module. Urchin was a company that Google bought back in 2005. Back when you could still hear the screech of a dial-up modem.
Enough about what they are, how do they work? Use this UTM creator that Google made for Google Analytics. Plug in your variables and the tool spits out your fancy link.
There are six of these variables to consider. They're all supposed to signify something different, but that isn't correct; you can put whatever you want in each one. On the other hand, It is easier if you stick to the strategy designed for them. Assume the tools you use are doing that. Save yourself the trouble and go with the flow. The variables are as follows:
Campaign ID: This is another variable that helps you tell your different ad campaigns apart. It’s optional, but if you’ve created a lot of campaigns it’s usually helpful to have something else to tell them apart.
Campaign Source: Use this variable to describe whether this ad campaign is going through a search engine, an email newsletter, etc.
Campaign Medium: Here you’re describing the medium of the campaign, like a blog, email, cost-per-click ad, and so on.
Campaign Name: This is for helping with keyword research and is usually the name of the actual ads campaign, like spring sale.
Campaign Term: This is helpful when you’re running paid ads, and is good for remembering which keywords you bid on for the ad.
Campaign Content: This last one is helpful for when you decide to split test your ad, that way you can tell them apart. It’s also the most common one used for differentiating two otherwise identical URLs.
