frequently asked questions
How do I determine advertising effectiveness?
Edison interviewers conduct in-person intercepts in any location where people are exposed to advertising. Connecting with people before and after they are exposed to your advertising allows us to measure lift in brand awareness, attitudes toward a brand, and purchase intent.
How can I measure my audience?
Edison starts by selecting a representative sample of locations in your network of locations. Depending on your goals, Edison may use a combination of tally counts and exit polls over multiple days and dayparts to determine audience.
Interviewers record counts of people entering or exiting a particular venue or of people that pass within the “vehicle zone”. Note: A “vehicle zone” is the physical area in which a person is able to see and/or hear specific, place-based advertising.

What’s a good/valid sample size?
The sample size Edison recommends for your project will depend on your business and your goals. While some situations may call for a survey that represents your entire network, others may be better handled with a smaller “snapshot” or case study.
Another factor in determining an appropriate sample size, is how the data needs to be analyzed. If examining the “total” sample is sufficient, a smaller sample size may be needed than in a situation where particular demographic groups or geographies need to be evaluated.
What can I do to ensure in-person research goes smoothly in my network of locations?
Edison interviewers will often need permission to enter and conduct research at retail or other locations. Communication with your clients is important to the research process.
Loop Edison into the process and we will explain who we are and what our process is and make sure the project runs smoothly. Another good idea is discussing the idea of research early on with your clients or considering building research days it in to your agreement with each client.
Do you have interviewers in Anywhere, USA?
Since 2003 we have provided election projections and analysis for the news organizations that comprise the National Election Pool (NEP): ABC, CBS, CNN, Fox, NBC and the Associated Press. Read more about election polling here.
After over ten years of election polling and out-of-home research, our nationwide database of interviewers tops 17,000. So, whether your network of locations reaches big cities to rural towns, a trained Edison interviewer is nearby.
What can I expect of your interviewers?
Edison interviewers are trained on the specifics of each individual project they are assigned. Throughout the fielding period, they are monitored by and have contact with an Edison project manager. Upon arrival at each location, they are instructed to introduce themselves to the manager and provide any permission letter and/or contact letters from corporate.
