There is little standardization concerning how cookie banners are deployed. Generally, however, most cookie banners fall within four broad categories:
- Deemed consent cookie banners. A deemed consent cookie banner discloses to website visitors that the website deploys cookies and asserts that visitors’ continued use of the website constitutes deemed, or implied, consent for the placement of cookies.
The following indicates the percentage of companies within the Fortune 500 that deploy each type of cookie banner:
|Type of Cookie Banner||Percentage|
|Notice and deemed consent||9.6%|
|Notice and opt-out||5.8%|
|Notice and opt-in||28.5%|
 Greenberg Traurig LLP reviewed the publicly available privacy notices and practices of 555 companies (the Survey Population). The Survey Population comprises companies that had been ranked within the Fortune 500 at some point in the past five years as well as additional companies selected from industries that are underrepresented in the Fortune 500. While the Survey Population does not fully match the current Fortune 500 as a result of industry consolidation and shifts in company capitalization, we believe that the aggregate statistics rendered from the Survey Population are representative of mature companies. Greenberg Traurig’s latest survey was conducted between September and October 2022. Websites were visited using the Chrome browser from an IP address associated with California.
