A Comfortable Strategy

Social Media Marketing

We relied heavily on A/B testing with Facebook advertising for the client. After thoroughly testing out a national Trane campaign, in which the client provided graphics for us, we got curious and wanted to see if our own ads could do any better. So we tested it.

Optimizing Your Advertising Budget

PPC Marketing

With a broad service area and a wide variety of services available, our Google AdWords strategy required very specific targeting based on geography and careful keyword selection. By writing relevant ads, creating service and area specific landing pages, and watching bids closely we were able to drive down the cost per click as well as cost per lead driven by Google AdWords.



Lowered From $8.74 To $6.82

Construct An Effective Strategy

Email Marketing

Testing and personalization were the keys to a cool email strategy for Carolina Comfort Air. To ease first appointment jitters we began a program of appointment reminder emails. We also sent monthly marketing emails that included a clear call to action. Our email marketing efforts resulted in great improvements in conversion rates and rock bottom unsubscribe rates.
