Does US law require a cookie banner?
The sources reviewed do not require one. They require opt-out methods that work, and a banner is one optional way to present a choice.
The California regulations never tell a business to display a banner. They tell a business that sells or shares personal information to provide methods for people to opt out, to post a specific link or an approved alternative, and to process opt-out preference signals. Colorado's and Connecticut's Attorneys General describe their laws in the same opt-out terms.
The research notes behind this article draw the same conclusion as an inference: US state privacy law is opt-out for most data, so a tag firing before a banner click is not by that fact alone a violation of those acts. The notes add that the legally strongest finding against a US site is that it ignores opt-outs.
Two cautions apply. Each state law covers only businesses above its thresholds. And other laws can apply to particular kinds of data, which this article does not review. This article describes what the sources say and is not advice about a particular site.

What does California require of a site that sells or shares data?
At least two opt-out methods including browser signals, a visible opt-out link or approved alternative, and action within 15 business days.
Section 7026 says a business that sells or shares personal information 'shall provide two or more designated methods for submitting requests to opt-out'. A business that collects personal information online must, at a minimum, accept an opt-out preference signal and offer at least one more method. The regulation lists an interactive form reached through the 'Do Not Sell or Share My Personal Information' link, the alternative opt-out link, or the privacy policy where the business processes signals in a frictionless manner.
Section 7013 describes the link. It must be conspicuous and located in the header or footer of the homepage. Clicking it must either opt the person out immediately or take them to a page where they can make that choice.
The methods have to be easy. The business may not require an account or more information than is needed, and may not require a verified request. Once a request arrives, the business must stop selling and sharing 'as soon as feasibly possible, but no later than 15 business days', and must notify the third parties that received the data.
The text quoted in this article is the version published by Cornell's Legal Information Institute. The privacy agency has amended its regulations since then, so check the agency's current text before relying on a subsection number.
Why is a cookie banner alone not an opt-out in California?
Because the regulation says cookies concern the collection of personal information, while the opt-out right concerns its sale and sharing.
The sentence is in section 7026(a)(4): 'A notification or tool regarding cookies, such as a cookie banner or cookie controls, is not by itself an acceptable method for submitting requests to opt-out of sale/sharing because cookies concern the collection of personal information and not the sale or sharing of personal information.' It continues that an acceptable method 'must address the sale and sharing of personal information'.
The Sling TV settlement shows the rule applied. The Attorney General's announcement says Sling TV 'combined cookie preferences with the CCPA opt-out, even though to truly opt-out, turning off cookies was insufficient'. People had to find an embedded link to a web form and click through confirmation steps. Under the settlement Sling TV must stop directing people who want to opt out to cookie preferences. The settlement included $530,000 in civil penalties and was subject to court approval when announced.
The practical reading is that a banner can sit in front of an opt-out system. It cannot be the whole system. Data can be shared through routes a cookie toggle does not reach, and the regulation expects the opt-out to cover the sharing itself.
How must a banner be designed if you use one?
The choices must be equally easy to take, the wording must be clear, and the design must not push the visitor toward the less private option.
Section 7004 sets design principles for any method of submitting a privacy request or obtaining consent. The central one is symmetry in choice: the path to the more privacy-protective option 'shall not be longer or more difficult or time-consuming' than the path to the less protective one.
The regulation gives a banner as an example. A website banner offering only 'Accept All' and 'More Information', or 'Accept All' and 'Preferences', is 'not equal or symmetrical' because one click accepts everything while declining takes extra steps. It says an equal choice could be between 'Accept All' and 'Decline All'.
The section ends with the consequence. A method that does not follow these principles 'may be considered a dark pattern', and agreement obtained through dark patterns does not count as consent.
| Design choice | What section 7004 says |
|---|
| 'Accept All' beside 'More Information' or 'Preferences' | Not symmetrical. Accepting takes one step and declining takes more |
| 'Yes' and 'Ask me later' | Not symmetrical. There is no option to decline |
| 'Yes' or 'No' next to 'Do Not Sell or Share My Personal Information' | A double negative and a confusing choice |
| Toggles labeled only 'on' and 'off' | May be confusing and may need clarifying language |
| Screens the visitor must click through before opting out | Choice architecture that impairs the ability to choose |
| Making the visitor scroll through a privacy policy to find the opt-out | Adds unnecessary burden after clicking the opt-out link |
| Broken or circular links that the business knows about | May be a violation if not remedied |
What have regulators penalized in banners and consent tools?
Banners that claimed to stop tracking and did not, tools that made the private choice harder, a forced agree screen, and a misconfigured portal.
The five matters below come from the regulators' own announcements, except PlayOn Sports, which is taken from a WilmerHale summary of the agency's decision because the agency's page could not be opened.
In the Todd Snyder decision the privacy agency's head of enforcement, Michael Macko, said: 'Using a consent management platform doesn't get you off the hook for compliance.' The agency's announcement adds that businesses should scrutinize their privacy management tools to make sure they work as intended.
| Company | Amount and date | What the banner or tool did |
|---|
| Honda | $632,500, 12 March 2025, privacy agency | Online privacy management tool did not offer privacy choices in a symmetrical or equal way |
| Todd Snyder | $345,178, 6 May 2025, privacy agency | Privacy portal was not properly configured, so opt-out requests went unprocessed for 40 days |
| Healthline | $1.55 million, 1 July 2025, Attorney General | Consent banner did not disable tracking cookies despite purporting to do so when a box was unchecked |
| Sling TV | $530,000, October 2025, Attorney General | Sent people to cookie preferences when turning off cookies did not opt them out |
| PlayOn Sports | $1.1 million, announced 3 March 2026, privacy agency | Mobile screen required people to click 'Agree' to tracking before redeeming tickets they had bought, as reported by WilmerHale |
What do other states ask for?
The two other state pages opened describe an opt-out link and a duty to honor browser signals, with no mention of a banner.
Colorado's Attorney General says that since 1 July 2024 businesses within the Colorado Privacy Act's thresholds must allow people to opt out of the sale of personal data or its use for targeted advertising using Global Privacy Control. Businesses must also explain in their privacy policy how requests made through such mechanisms are processed.
Connecticut's Attorney General says a controller must provide an easily accessible link on its website through which people can opt out of targeted advertising or the sale of their personal data. Since 1 January 2025, controllers must also honor opt-out preference signals.
These two are examples. The California privacy agency wrote in October 2025 that about a dozen states require businesses to honor opt-out signals. Each law has its own scope and wording, and this article did not review the rest.
How often do banners fail to stop tracking?
One 2025 vendor audit of 450 US sites reported that 79% still loaded an advertising or targeting tag after an opt-out.
The audit is from InfoTrust, which sells consent and analytics services. It reported that the typical site fired 25 tracking tags before any consent interaction, that nearly one in four sites made no change at all based on the visitor's choice, and that the median site kept sharing data with five advertising or analytics vendors after an opt-out. The public page does not describe how sites were chosen or how tags were detected.
These are one vendor's numbers for one sample. They line up with the regulator cases, which describe controls that looked correct and did not work. A banner is an interface. Whether a tag stops depends on how that tag was installed and whether the banner is wired to it.
The research notes record one cause from a vendor guide: a pixel hard-coded into a page can fire before the tag manager loads, so consent settings in the tag manager may not stop it. That is a single vendor's explanation, and it matches the kind of gap the Todd Snyder and Healthline matters describe.
A banner checklist drawn from the regulations
Check that the opt-out exists apart from the banner, that the banner offers equal choices, and that each choice changes what loads.
The list follows the California sections quoted above and the facts of the cases. It is a way to compare a banner with what the sources describe. It is not a statement of what any particular business must do.
- Confirm the site has an opt-out method that addresses sale and sharing, reachable from a 'Do Not Sell or Share My Personal Information' link or an approved alternative.
- Confirm the site processes a browser opt-out signal with no banner interaction.
- Count the clicks to accept and the clicks to decline. They should be equal.
- Read each button and toggle aloud. Remove double negatives and bare on and off labels.
- Decline, reload, and record which advertising and analytics tags still load.
- Check tags placed outside the tag manager, which a banner may not control.
- Confirm no screen forces agreement before a visitor can use something they already paid for.
- Retest after every change to tags or the consent tool, and keep the dated result.
