How to stop ads following you online
The ads that follow you across websites are powered by retargeting pixels — small tracking scripts that record your visits and report them to ad platforms so they can show you related ads for days or weeks. PrivacyGuard blocks these pixels so retargeting data is never collected in the first place.
Why do ads follow me after I visit a website?
When you visit a website with a Facebook Pixel or Google Ads tag, that script reports your visit to the ad network. The network then adds you to a retargeting audience and serves you ads for that brand on any other website or app that uses their ad network. This is why you see furniture ads after browsing a furniture site.
Does clearing cookies stop retargeting ads?
Clearing cookies reduces some retargeting but does not eliminate it. Modern retargeting uses fingerprinting (device characteristics) and hashed identity matching (email addresses you have given to sites) that persist beyond cookie clearing. The most effective approach is blocking the tracking pixel before it fires, which is what PrivacyGuard does.
Does PrivacyGuard affect websites I want to support?
PrivacyGuard blocks tracking scripts, not content. Websites you visit still receive your visit and any direct clicks — the only thing blocked is the data flowing to third-party ad networks. Many creators and publishers prefer PrivacyGuard users over ad-tracked users because the relationship is direct rather than intermediated by ad networks.
