The 710 brands in YouGov BrandIndex were ranked based on the Index score, which is a measure of overall brand health calculated by taking the average of Impression, Quality, Value, Satisfaction, Recommend, and Reputation.

The Index Rankings chart shows the brands with the highest average Index scores for the 12 month period from July 1, 2018 through June 30, 2019. The Index Improvers chart ranks the brands with the highest increase in Index, comparing scores from the previous 12-month period. All scores are based on a representative sample of the general population of adults 18+.

All Index scores listed have been rounded to a single decimal place; however, we have used additional precision to assign ranks.

All brands must have been 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.
