YouGov BrandIndex Brand Advocacy Scores are calculated by measuring Recommend Scores among each brand’s customers for the twelve-month period through October 2016. Recommend scores for the brands are measured by asking, "Would you recommend the brand to a friend or family member, or would you recommend that a friend or family member avoid the brand?" Scores are calculated by subtracting the negative responses from the positive responses.
YouGov BrandIndex interviews thousands of consumers every day, yielding over 6 million interviews each year. Respondents are drawn from our online panels of 4 million consumers across 32 markets. YouGov BrandIndex currently covers 280 brands in Thailand.
*Note: YouGov BrandIndex started tracking brands under retail sectors in Thailand in January 2016.
