YouGov BrandIndex were ranked using the Buzz score which asks respondents, “If you've heard anything about the brand in the last two weeks, through advertising, news or word of mouth, was it positive or negative?” Scores are net scores, calculated by subtracting the percentage of negative responses from the percentage of positive responses for each brand.
The Buzz Rankings chart shows the brands with the highest average Buzz scores between January 1st and December 31st, 2019. The Buzz Improvers chart ranks the brands with the highest increase in Buzz comparing scores in years 2018 and 2019, to be included in the Buzz Improvers list, the variance must be positive. Scores are representative of the general population.
All Buzz scores listed have been rounded to a single decimal place; however, we have used additional precision to assign ranks.
All brands must be tracked for at least 6 months to be included in the rankings, and must have been tracked for at least 6 months in the prior year’s period (as well as being currently tracked) to appear in the movers tables.
