Medical Guardian

Client Story

Medical Guardian’s mission is to empower older adults to live a life without limits. Medical Guardian sells in-home and personal medical alert systems that allow the user to communicate with a certified medical operator in the event of an emergency, giving security and peace of mind to the user and their loved ones. Before working with Metric Theory, Medical Guardian was investing in paid search, but many of its sales closed when the customer called their phone number, so they could not identify which campaigns and keywords drove the most orders.


The Strategy: Increase SEM Sales

Track Phone Calls: Metric Theory integrated our technology partner Kenshoo directly with Marchex, Medical Guardian’s phone call tracking software to allow us to identify how many phone calls came from every campaign and calculate the cost per lead from each campaign

Track Qualified Leads: Metric Theory implemented UTM parameters to track each incoming lead back to the campaign, keyword and ad that drove this lead. We then created a custom Salesforce report to calculate the cost per qualified lead and conversion to qualified rate of every incoming lead.

Identify Top Performers: With data in hand, Metric Theory identified top performing keyword sets and expanded upon them to grow total leads as well as qualified leads and revenue.
