Consent rate is the percentage of website visitors who accept some or all non-essential cookies when presented with a consent banner. It is calculated as: (visitors who gave consent ÷ total visitors shown the banner) × 100. Consent rate is a key metric for evaluating cookie banner performance — a low rate may indicate a poorly designed banner, too many cookie categories, or excessive friction in the opt-in flow. Average industry consent rates typically range from 40% to 80% depending on region, industry, and banner design. A consent management platform should provide consent rate reporting as a core analytics feature.
