The 1590 brands in YouGov BrandIndex were ranked using the Impression score, which asks respondents, “Overall, of which of the following brands do you have Positive/Negative impression?” Scores are net scores, calculated by subtracting the percentage of negative responses from the percentage of positive responses for each brand.

The Women’s Rankings chart shows the brands with the highest average Impression scores between February 1, 2018 and January 31, 2019. The Impression Improvers chart ranks the brands with the highest increase in Impression comparing the scores for this year and the prior 12 month period (February 1, 2017 and January 31, 2018). To be included the year over year variance must be positive. Scores are representative amongst women.

All Impression 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.
