Based upon a review of the websites of the Fortune 500 conducted approximately one year after the CCPA went into effect, 21.4% of websites included a “do not sell my personal information link.” 78.6% of websites did not include a link to opt out of the sale of personal information.¹ A review of the websites of the Fortune 500 conducted in December 2019, immediately prior to the CCPA going into effect, showed that among companies that had already updated their websites to account for the CCPA, 18% had included a “Do Not Sell My Personal Information” link. Throughout the course of 2020 that number rose only three percentage points to 21.4%.²
