Turn Off Ad Personalization
The ads follow you because your profile says they should — your searches, videos, and demographics, packaged for advertisers. Ad personalization is the switch that lets platforms use your data to pick your ads. Turning it off does not remove ads, but it stops them from being chosen by your personal history.

TL;DR / Quick Fix
Quick fix: turning off ad personalization stops platforms from using your searches, watch history, and demographics to choose your ads. Find it in your Google account under Data & Privacy > Ad personalization. You will still see ads — they just will not be picked from your personal profile.
Follow these steps
- Open your ad personalization settings. In your Google account, go to Data & Privacy, then Ad personalization. This is the master switch for Google's ad profiling of you.
- Turn the switch off. One toggle stops Google from using your activity and demographics to personalize ads. The change applies across Search, YouTube, and partner sites.
- Do the same on other platforms. Meta, Amazon, and Apple each have their own ad-preference pages with equivalent switches. Google's toggle does not cover them — audit each major platform once.
- Clear existing ad interests. Platforms show the interest categories they assigned you — remove them. It is satisfying and it actually reduces the stored profile, not just future collection.
- Keep your activity controls tight too. Ad personalization reads your activity history — pairing this switch with auto-delete shrinks what there is to personalize from.
- Expect generic ads, not zero ads. You will see ads for things you never searched for — which is the point. Fewer creepy coincidences, slightly less relevant offers.

What NOT to do
- Do not expect an ad-free internet. This switch changes which ads you see, not whether you see them.
- Do not confuse this with app tracking settings. This governs ad profiling; the Ask App Not to Track prompt governs cross-app data sharing — related but separate.
- Do not assume one platform's switch covers the web. Ad networks beyond the big platforms have their own opt-outs; the big four cover most of what you will notice.
- Do not re-enable it accidentally during account setup. New devices and fresh installs sometimes default it back on — check after setting up.
Frequently asked questions
Will I still see ads for things I searched?
Less so. Without personalization, advertisers cannot target your search history — you get contextual ads (based on the page you are on) instead of behavioral ones (based on you).
Does this stop data collection?
No — it stops the data being used for ad targeting. Collection is governed separately by activity and history controls.
Is there a downside?
Slightly less relevant ads and recommendations. Most people consider generic ads a small price for not being profiled.
