Opt Out of Targeted Ads: Shopping Sites Guide

This guide walks you through reducing or stopping targeted ads on major shopping websites. You’ll learn how to adjust ad preferences, use browser tools, and manage cookies so the products you see are less tied to your browsing history. You’ll need access to your account settings on each site and a web browser (desktop recommended for full options).

What You’ll Need

• Account login credentials for each shopping site (Amazon, eBay, Walmart, etc.)
• A desktop or mobile web browser (Chrome, Firefox, Safari, Edge)
• Optional: A browser extension that blocks trackers (e.g., Privacy Badger, uBlock Origin)
• Optional: A VPN if you want to mask your IP address (not required for most settings)

Step-by-Step

1. Start with the biggest sites you use. Log into each shopping site where you have an account. Common ones: Amazon, eBay, Walmart, Target, Etsy, and Best Buy. The steps below work for most, but exact menu names may vary.
2. Find the ad preferences page. Look for “Your Account,” “Settings,” “Privacy,” or “Advertising Preferences.” On Amazon, go to Accounts & Lists > Your Account > Advertising Preferences. On eBay, go to Account > Communication Preferences > Marketing Preferences. On Walmart, go to Account > Settings > Privacy & Ads.
3. Turn off personalized ads. On the ad preferences page, you’ll see a toggle or checkbox for “Personalized ads” or “Interest-based ads.” Turn it off. This stops the site from using your browsing and purchase history to tailor ads. Note that you may still see generic ads, but they won’t be based on your behavior.
4. Clear or reset your advertising ID. On mobile apps, look for “Reset advertising identifier” (iOS) or “Delete advertising ID” (Android). On desktop, clear your cookies for the site (see step 6). This removes the data already collected.
5. Adjust cookie settings. Most shopping sites have a cookie banner. Click “Cookie Settings” and uncheck “Advertising” or “Targeting” cookies. If there’s no banner, use your browser’s cookie controls (see step 6).
6. Use your browser’s privacy settings. In Chrome, go to Settings > Privacy and Security > Cookies and other site data. Enable “Block third-party cookies.” In Firefox, go to Settings > Privacy & Security and select “Strict” mode. In Safari, go to Preferences > Privacy and enable “Prevent cross-site tracking.” This stops advertisers from following you across sites.
7. Install a tracker-blocking extension. Add Privacy Badger, uBlock Origin, or Ghostery to your browser. These block scripts that collect your data for ad targeting. After installing, they work automatically, but you may need to reload shopping pages.
8. Opt out of ad networks directly. Visit the Digital Advertising Alliance’s opt-out page (youradchoices.com) or the Network Advertising Initiative (networkadvertising.org). These let you opt out of many companies at once. Follow the instructions to set your opt-out cookie.
9. Use a private or incognito window for shopping. When you don’t want your browsing to affect ads, use incognito (Chrome), Private (Safari/Firefox), or InPrivate (Edge). This won’t save your history or cookies, so the site can’t build a profile.
10. Log out of accounts when not needed. If you’re just browsing, don’t stay logged in. This prevents the site from linking your session to your account history.

Common Mistakes

• Only turning off ads on one site. Each site has its own settings. You must repeat the process on every shopping site you use.
• Expecting zero ads. Opting out of targeted ads doesn’t remove ads entirely. You’ll still see ads, but they’ll be generic or based on the current page, not your history.
• Clearing cookies without changing settings. If you clear cookies but don’t turn off personalization, the site will start collecting again on your next visit.
• Using only a VPN. A VPN hides your IP but doesn’t stop cookies or tracking scripts. You still need to adjust settings.
• Forgetting mobile apps. Shopping apps have separate ad IDs. You need to reset them in your device settings and also turn off personalization in the app’s settings.

Tips

• Re-check settings every few months. Sites update their policies and may reset your preferences after major updates.
• Use a dedicated email for shopping. This doesn’t stop ads, but it keeps promotional emails separate and reduces cross-site tracking if you use the same email for logins.
• Combine with a privacy-focused browser. Browsers like Brave or Firefox with strict tracking protection block many ad trackers by default.
• Use a search engine that doesn’t track. DuckDuckGo and Startpage don’t track your searches, so shopping searches won’t feed ad profiles.
• Check your Google and Facebook ad settings. If you use these to log into shopping sites, they may share data. Go to Google Ad Settings and Facebook Ad Preferences to turn off personalized ads there too.

Troubleshooting

• You still see targeted ads after changing settings. Clear your cookies and cache, then restart your browser. If that doesn’t work, the site may have a separate “interest” section (like Amazon’s “Improve Your Recommendations”) that you need to clear manually.
• The ad preferences page is hard to find. Search the site’s help center for “advertising preferences” or “personalized ads.” If you can’t find it, contact customer support and ask for the direct link.
• Settings revert after a few days. Some sites use a cookie to store your opt-out. If you clear cookies, you lose it. Re-do the opt-out and, if possible, use the site’s “remember this choice” option. Alternatively, use a browser extension that persists your opt-out.
• You see ads from a site you never visited. This is from third-party cookies or data brokers. Use the DAA/NIA opt-out tools and enable “Do Not Track” in your browser (though not all sites honor it).
• Mobile app still shows targeted ads. Reset your advertising ID: on iPhone, go to Settings > Privacy > Tracking > Reset Advertising Identifier. On Android, go to Settings > Privacy > Ads > Reset advertising ID. Then re-check the app’s ad settings.

Frequently Asked Questions

Will I stop seeing ads completely? No. You’ll still see ads, but they won’t be based on your browsing or purchase history. They’ll be generic or contextual (e.g., a banner for a product on the page you’re viewing).

Does opting out work on all devices? No. Your ad preferences are usually tied to your account, so they apply to any device where you’re logged in. However, device-level settings (like advertising ID resets) are per device.

How long does it take to see a difference? It can take a few days to a couple of weeks. Advertisers may have already collected data, and some campaigns run for a while before expiring.

Is it legal for sites to ignore my opt-out? In many regions (like the EU under GDPR and California under CCPA), sites must honor opt-outs. In the US generally, it’s not as strict, but most major retailers comply. If you’re concerned, check the site’s privacy policy.

Do I need to do this on every site? Yes. Each site has its own ad system. There’s no single global switch, though the DAA/NIA opt-out tools cover many ad networks at once.

Will clearing cookies reset my opt-out? Yes, if the opt-out is stored as a cookie. That’s why using a browser extension or the site’s account-based preference is more permanent.
