In previous articles we’ve explored optimizing the conversion rate of call only text ads. Now we take another approach, minimizing the cost of PPC text ads. You can, of course, limit the cost-per-click (CPC) for particular campaigns, but set your CPC limit too low and Google will flag your campaign as “limited” by click budget. One approach we’ve found to be effective is abbreviating commonly used phrases. Abbreviation lets you squeeze in more text into a headline, or use shorter headlines.
Abbreviating PPC Ad Text
Abbreviation shortens longer words into shorter representative phrases, like “lb” for “pound” or “Mich” for “Michigan.” In this case we took one of the best performing ads for our Michigan car ride company and abbreviated the business name (see Figure 1).
The Business Name is “Michigan Green Cars.” The ad above converted well (over 90%) but the cost per conversion (i.e., a call) was $1.61. Abbreviating the word “Michigan” to “Mich” produced this otherwise identical ad (see Figure 2).
The second ad has “Mich Green Cars.” as the business name.
Results After Abbreviation
While the abbreviated ad has a slightly lower clickthrough rate, the CPC is 13.8% lower ($1.45 to $1.25) and due to the higher conversion rate the cost per call is 35.4% lower ($1.61 to $1.04/call, see Figure 3).
Why Abbreviate Ad Text?
Writing great PPC text ads is about grabbing their attention and spelling out key benefits to your product or service. We believe that abbreviations garner a bit more attention than longhand equivalents, are naturally more succinct, and make for shorter and snappier headlines. Of course, be sure to stay within Google’s Ad Text guidelines to avoid any issues.
In our testing we’ve found that abbreviating key phrases in PPC text ads can lower CPC and the cost per conversion. In fact, abbreviation can also improve conversion rates by providing attention getting phrases for fast scanning eyeballs. Our otherwise identical text ad with “Michigan” abbreviated to “Mich” decreased the cost per call by more than 35%, and increased the conversion rate by 33 percentage points.
