Case Study: Adster Creative achieves 20% increase in client retention with CallRail

Digital Marketing Agency Increases Client Retention Rate by 20% with Call Analytics

Adster Creative, an Edmonton-based digital marketing agency specializing in SEO, Google Ads and website optimization for local service businesses, struggled to quantify phone-call ROI for clients because tools like Google Analytics didn’t show call conversions. After a limited attempt to build an in-house tracker, Adster adopted CallRail’s call analytics and tracking (including call recording and call-extension numbers for Google Ads) to gain accurate visibility into which campaigns, landing pages, and keywords were driving phone leads.

CallRail’s analytics and API allowed Adster to feed call data into their custom SuperDash reporting dashboard, enabling lead qualification, keyword-level attribution, and transparent client reporting. The result was clearer evidence of marketing ROI, better coaching on call handling, and improved campaign decisions — and a measurable business impact: Adster Creative’s client retention rate increased by 20% after implementing CallRail.
