Yahoo! Web Analytics
Yahoo! Web Analytics was a free web analytics product retired by Yahoo in 2012; legacy tags can still load defunct beacons and dropped cookies that should be removed.
What does Yahoo! Web Analytics do?
What Yahoo! Web Analytics was
Yahoo! Web Analytics was a free site analytics product launched in 2008 after Yahoo acquired IndexTools. It was retired by Yahoo in 2012, with users invited to migrate to other tools. Despite the shutdown, the JavaScript tag is still found on long lived sites, mostly because the snippet was never removed during a CMS migration.
Cookies and data on legacy tags
Where the tag still loads, it tries to write cookies named WEB_ID and WT_FPC and to beacon page view data to a Yahoo endpoint that no longer accepts traffic for most accounts. Even when the beacon fails, the cookies are still written, and the JavaScript loads a third party script from a Yahoo controlled domain.
GDPR and ePrivacy implications
The cookies and the third party script are non essential, so article 5(3) of the ePrivacy Directive still applies. Asking visitors to consent to a dead service is poor practice and risks complaints. The privacy notice must either reflect the residual processing or, preferably, the tag should be removed.
How to clean up
Search the codebase for d.yimg.com, web-analytics.yahoo.com or the WEB_ID cookie. Remove the inline snippet, purge cached versions in your CDN, and flush any remaining cookies via a small script that deletes them on the first matching domain visit.
Data transfers
Yahoo (now part of Apollo Global Management as Yahoo Inc.) operates from the United States. Even residual beacon attempts therefore qualify as a transfer to a third country. Removing the tag is the simplest way to eliminate the transfer.
Practical compliance steps
Treat any detection of Yahoo! Web Analytics as a tag hygiene incident. Remove the snippet, document the cleanup in your records of processing activities, scan for similar dead tags such as Google Urchin or Compete, and add a periodic audit to your privacy review.
Yahoo! Web Analytics and the GDPR
Yahoo! Web Analytics is classified as “Analytics”. On a site that targets European visitors, it must only load after the visitor consents, and it must be listed in your cookie policy.
- Legal basis
- Consent (Art. 6(1)(a) GDPR) for any remaining Yahoo Web Analytics cookies; in practice the recommendation is to remove the tag entirely
- Risk level
- high
- Applicable regulations
- GDPR, ePrivacy Directive, EU-US Data Privacy Framework, French Loi Informatique et Libertés
Impact assessment (DPIA)
A DPIA is largely moot for a product that no longer accepts new data, but the residual cookies and beacons still trigger ePrivacy obligations. Operators should remove the tag and document the cleanup; the broader risk is that legacy code shows lack of governance.
Sample text for your banner
A legacy Yahoo! Web Analytics tag was detected on this page. The product has been discontinued, but the tag may still set cookies. By accepting, you allow these residual cookies; we recommend removing the tag rather than asking visitors to consent to a dead service.
What Yahoo! Web Analytics sets and contacts
- Tracking method
- Legacy Yahoo! Web Analytics JavaScript tag that captured page views, events and session data; the product was discontinued by Yahoo in 2012 and any remaining tags now point to defunct endpoints
- Server location
- Historically United States, Yahoo data centres; the service is no longer operational
- Data transferred outside the EU
- Even though the service is discontinued, residual cookies and beacon calls are routed to Yahoo or its successor entities (Verizon Media, Yahoo Inc.) on US infrastructure.

Frequently asked questions about Yahoo! Web Analytics
Can't find your question? Write to us, we answer fast.
What cookies does Yahoo! Web Analytics set?
When the legacy tag still loads, it tries to set WEB_ID and WT_FPC cookies plus session cookies on the visitor browser, even though the underlying service no longer accepts new traffic for most accounts.
Do I need consent to keep a Yahoo! Web Analytics tag?
Yes if any cookie is still set or any third party script still loads. The service is discontinued, so the simplest answer is to remove the tag rather than gather consent for a defunct product.
What is the legal basis for residual Yahoo! Web Analytics processing?
Consent is the only realistic basis if the tag remains active. Legitimate interest is hard to argue when the destination platform no longer exists and the operator has no business need.
Does Yahoo! Web Analytics transfer data to the United States?
Yes by design. Yahoo Inc. is US based, so even residual beacon attempts go to US infrastructure. Removing the tag is the cleanest way to end the transfer.
Do I need a DPIA for Yahoo! Web Analytics?
In practice no, because the service is dead. The expected response is to remove the tag and document the cleanup, not to perform a full DPIA on a non functional product.
How do I implement compliance for legacy Yahoo! Web Analytics tags?
Search the codebase for d.yimg.com or web-analytics.yahoo.com references, remove the snippet, purge CDN caches, drop residual WEB_ID and WT_FPC cookies, and document the cleanup in your tag inventory.
What are the alternatives to Yahoo! Web Analytics?
Modern analytics that fit a privacy aware EU posture include Matomo, Plausible, Fathom, Cabin, Piwik PRO, Google Analytics 4 with a strict consent setup or Adobe Analytics with EU residency.
How should I update my cookie policy after removing Yahoo! Web Analytics?
Remove all references to Yahoo! Web Analytics from the cookie policy, confirm the cookies are no longer set, replace with the documentation of the analytics platform you use today, and add a periodic dead tag audit.
