For over 35 years, GfK Retail and Technology USA has been the leader in measuring the effectiveness of point-of-purchase advertising and promotional media. Having conducted more than 5,000 tests, we have both the experience and the expertise to handle all aspects of the research process.
The primary measure of success is increased sales, clear-cut evidence of bottom-line ROI.
A frequently used methodology for in-store tests is the matched panel design which offers the benefits of efficiency and effectiveness on both a measurement and a cost basis.
In brief, this technique involves the set up of two (or more) panels of stores which are matched as closely as possible on pre-set criteria during a non-test "base” period. The test variable (an in-store ad, display, aisle violator, coupon dispenser, shelf talker, etc.) is then introduced into one of these panels and results are compared to the other non-test panel.
A major strength of this design is in the reliability and clarity of reading results.
Sales (and share) performance can be compared directly in two ways:
|
TEST PANEL |
|
<------> CONTROL PANEL |
|
BASE PERIOD |
|
<------> TEST PERIOD |
A straightforward calculation of indices provides a picture of the results; a statistical analysis determines the validity vs. the pre-determined objective.
GfK RT USA has worked with almost every major retail chain organization in the U.S. across the complete spectrum of trade channels. We can assist you in acquiring the retailer’s cooperation to conduct the test and collect the POS data necessary to complete the initial matching process as well as the test and post-test reporting.
All data are collected at the individual UPC/SKU level which can then also be aggregated to provide data by types, formulas, sizes, brands, etc. up to and including the overall product category. Typically, reported measurements include the following by Base vs. Test vs. Post-Test periods:
Reports are graphically presented with full analysis and stat testing results to make them both comprehensive and actionable.
Our Field Management team can arrange for trained, local-market auditors and interviewers to execute any needed in-store monitoring or interviewing:
No other research partner can offer you a greater combination of experience, talent and capability. GfK Audits & Surveys provides:
If the P.O.P. to be tested is not limited to a specific store section and/or the product category is sold in more than one location in the store, then GfK RT USA's LocationScan™ may be the ideal measurement solution.
LocationScan™ provides the ability to measure sales and shares from every independent location where a product/category is located within the store. For example, a category such as Household Batteries could easily be sold in 8 or more locations in a mass merchandise outlet:
