No retailer is a clear all-around winner. Amazon spells out several controls for browsing history and recommendations, while Walmart and Target describe Global Privacy Control (GPC) opt-outs for certain advertising and data uses. eBay’s AdChoice offers a browser-based choice for customized ads. The best fit depends on whether you want to manage recommendations, limit targeted ads, or exercise a legal data right—and where you shop.
What “more control” means
Shopping-data control is not one setting. It can mean managing the history used for recommendations, opting out of interest-based advertising, keeping a preference active across devices, or requesting access to or deletion of personal data. Those controls have different scopes and conditions, so a single privacy score would be misleading.
- History and recommendations: Can you review or remove activity used to shape recommendations?
- Advertising: Does a choice cover ads on the retailer’s site, ads on partner sites, or both? Does it stop personalization or all ads?
- Persistence: Is the preference linked to your account or only to a particular browser or device?
- Data rights: Can you request access, correction, deletion, or an opt-out under the privacy laws that apply to you?
- Trade-offs: Does a setting affect shopping functions, require identity verification, or need to be repeated?
The comparison below reflects the companies’ official U.S.-focused materials. Privacy notices describe stated practices and options; they are not independent audits of every technical system. Legal rights and available settings vary by location.
How the retailers’ controls compare
| Retailer | Controls described | Important scope or caveat |
|---|---|---|
| Amazon | Account holders can access account information, including purchase history; change personalized advertising preferences; manage recommendations and browsing history; and remove an item from recommendation use. The U.S. notice says access or deletion may be available to the extent required by law. Amazon Privacy Notice | Signing out and blocking cookies can avoid linking browsing history to an account, but rejecting cookies may prevent cart, checkout, or sign-in functions. Amazon says ad companies may receive advertising identifiers and some ad-measurement information, but not specific purchases, product views, or searches. Amazon Privacy Notice |
| Walmart | Its notice describes account advertising settings, account access and updates, account deletion through Contact Us or an app link, and jurisdiction-specific choices such as access, correction, deletion, and opt-outs for targeted advertising or sale/sharing. Walmart also says it honors GPC for specified opt-outs. Walmart Customer Privacy Notice | Some ad choices require cookies and apply only to the current browser or computer; clearing saved cookies means repeating the choice. A GPC request made while signed in may extend to the account; while signed out, it applies to the browser sending the signal. Walmart says processing opt-outs for other data it holds can take up to 15 days. Walmart Customer Privacy Notice |
| Target | Its policy describes rights, where applicable, to access, correct, or delete data and opt out of specified targeted advertising, sale, or sharing. Target says it treats GPC as an opt-out signal for sale and targeted or cross-context behavioral advertising. Target Privacy Policy | Rights vary by state, and access and deletion requests require identity verification. The policy does not establish that every option is available on identical terms to every shopper. Target Privacy Policy |
| eBay | AdChoice lets shoppers opt out of customized advertising on eBay and partner websites. eBay also says users can request a copy of their data. eBay AdChoice | The AdChoice preference applies to the current browser, must be repeated on other browsers or devices, and is removed if its cookies are deleted. Ads may still appear, but are not customized based on eBay activity. eBay AdChoice |
Which retailer is best for browsing history and recommendations?
Amazon’s U.S. notice most explicitly describes shopper-facing controls for recommendations and browsing history. If your concern is that previous activity will shape what Amazon recommends, use those account controls to manage history and remove items from recommendation use. That is different from opting out of ads: changing recommendations does not, by itself, erase purchase history or close your account. Amazon Privacy Notice

Amazon also describes signing out and blocking cookies as a way to avoid linking browsing history to an account. That is not a promise that signing out prevents all tracking, and cookie blocking can interfere with cart, checkout, and sign-in features. Amazon Privacy Notice
Which retailer is best for limiting personalized ads?
There is no universal winner in the materials reviewed. Walmart and Target describe GPC as a way to signal certain opt-outs where applicable. Walmart’s notice also describes account and browser-based advertising choices; eBay’s AdChoice focuses on customized advertising on eBay and partner websites. Check what a particular setting covers before treating it as a broad opt-out.

- Compatible Models: Width: 13 9/16" (13.5 inch/344 mm), Height: 7 5/8" (7.6 inch/194 mm), Diagonal: 15.6" (396.24 mm) widescreen laptops which have a 16:9 aspect ratio.

An ad opt-out generally does not mean ads disappear. Walmart says opted-out shoppers may still see ads that are not interest-based, and eBay says ads continue but are not customized to the shopper’s interests. Walmart Customer Privacy Notice eBay AdChoice
Why GPC and browser-based choices may not follow you
GPC is a browser signal, and the effect depends on the company’s stated handling, the shopper’s sign-in status, the type of data, and applicable law. Walmart says an unsigned-in GPC request applies to the browser sending it, while a signed-in request may extend to the account. Walmart also says processing opt-outs for other held data can take up to 15 days. Target says it treats GPC as an opt-out signal for specified sale and targeted or cross-context behavioral advertising. Walmart Customer Privacy Notice Target Privacy Policy

Other choices may be saved in browser cookies rather than attached to an account. Walmart says some advertising opt-outs are limited to the current browser or computer, and eBay says its AdChoice preference is removed when the relevant cookies are deleted. If you shop in multiple browsers or on multiple devices, check each one and revisit the choice after clearing cookies. Walmart Customer Privacy Notice eBay AdChoice
Access, correction, deletion, and advertising are separate
Turning off personalized advertising is not the same as deleting shopping data. Amazon’s U.S. notice says access or deletion may be available to the extent required by law. Walmart and Target describe additional rights that depend on jurisdiction; Target says access and deletion requests require identity verification. Use the applicable retailer privacy-request route to ask for a copy, correction, or deletion, and check the rules for your location.

How to choose and apply the right setting
- For less personalized Amazon recommendations: Open your Amazon account’s recommendation and browsing-history controls, then manage history or remove items from recommendation use. The U.S. notice describes these options but does not establish that every account has an identical interface. Amazon Privacy Notice
- For fewer tailored ads: Find the retailer’s advertising-preference choice and, where supported and applicable, enable GPC in the browser you use to shop. Treat it as a limitation on specified ad uses, not a way to erase history or eliminate all ads.
- For a choice on more than one device: Check each browser and device. Revisit browser-based preferences after deleting cookies, since some saved opt-outs may be removed.
- For a copy, correction, or deletion: Submit a privacy request through the retailer’s official route and check whether the right applies in your jurisdiction. Be prepared for identity verification where required.
What changes for Amazon shoppers in the EU?
Amazon’s 2026 compliance report describes consent settings in the Data & Privacy section of account settings on EU Amazon Store domains and in the mobile shopping app. It says changes are timestamped and propagated across relevant Amazon systems. This is an EU-specific example; it should not be assumed to match the interface or choices available to U.S. shoppers. Amazon 2026 compliance report
Bottom line on control
Choose by the control you need, not by a single retailer ranking: Amazon describes the clearest recommendation and browsing-history tools; Walmart and Target document GPC handling for specified opt-outs; and eBay provides an AdChoice option for customized ads that is tied to the browser. None of these choices should be treated as total control over shopping data.
