United States Brand Tracker Methodology

Overview

Data quality

The United States Brand Tracker follows Conjointly’s rigorous quality standards, including:

  • Multi-layered quality controls throughout the research process
  • Bot blocking and prevention of repeat completions
  • Geofencing to ensure United States respondents
  • Detection of anomalous network activity
  • Automated flagging of low-quality responses
  • Final quality checks to remove and replace poor-quality data

Sampling and weighting

Respondents are recruited from Conjointly’s panel networks, with quota-sampling used to ensure demographic representativeness. Post-survey (raking) weighting is applied to adjust for key demographics such as age, gender, region, race, and other relevant factors based on US census data and official statistics.

Survey Method: Online survey sample

Category Exposure: Several categories are tracked. Each respondent was exposed to a maximum of 4 categories to ensure focused and high-quality responses.
