Your opt-out link says it works. Do your ad pixels agree?
An opt-out link or banner message can say a visitor's choice was honored while Meta, TikTok or LinkedIn pixels keep firing.
The short answer
A "Do not sell or share my personal information" link, or a banner that confirms an opt-out, is only as good as the tags behind it. If the Meta Pixel, TikTok Pixel or LinkedIn Insight Tag keeps sending data after a visitor opts out, the message on screen and what the site actually does no longer match.
Why this became a marketing question
Under several US state privacy laws, sending visitor data to ad platforms for retargeting can count as "sharing," even when no money changes hands. Regulators have been checking whether sites that say they honor opt-outs actually stop that data. That puts the pixels your marketing team relies on in scope.
A test you can run
- Open your site in a private browser window.
- Open the browser's developer tools and select the Network tab.
- Use your opt-out link or decline in the banner.
- Reload the page and click around, including a form or add-to-cart.
- Filter the network requests for
facebook,tiktokandlinkedin.
If requests to those platforms still go out, carrying page or event data, the opt-out isn't reaching the pixels.
Then repeat with Global Privacy Control turned on in your browser.
Common reasons it fails
- The pixel loads directly in the site's code, outside Tag Manager, so the consent rules in Tag Manager never apply to it.
- The opt-out sets a cookie, but no tag checks that cookie.
- The pixel is installed twice: once by a platform app and once in Tag Manager. Only one copy follows the opt-out.
- Meta's Limited Data Use setting isn't sent when it should be.
