Overview
Automattic is the company behind WordPress.com, WooCommerce, Jetpack, Tumblr, Akismet, and Day One. Its most significant presence on third-party websites is through Jetpack, a plugin installed on tens of millions of self-hosted WordPress sites that bundles analytics, security, performance, and content features into a single package.
What This Script Does
Jetpack's behavior varies by which modules are enabled. Each module has distinct tracking, data collection, and cookie behavior.
Jetpack Site Stats Module
- A 1x1 tracking pixel loaded from
pixel.wp.comfires on every page view. - The pixel passes: blog ID, page URL, referrer, and a visitor hash derived from IP and user agent.
- Data is processed on WordPress.com servers and displayed in the Jetpack stats dashboard.
- Sets
tk_orcookie — Tracks whether the visitor is a referral from WordPress.com. Persists for 1 year. - Sets
tk_aicookie — Anonymized visitor identifier used for unique visitor counting. Persists for 6 months.

Consent & Compliance
Consent category: Analytics / Functional (split by module)
- GDPR/ePrivacy: The Jetpack Stats pixel and visitor tracking cookies (
tk_or,tk_ai) require consent under ePrivacy as they track user behavior. Social sharing buttons that load third-party scripts (Facebook, Twitter) require consent for those platforms' cookies. Security and spam filtering modules can operate under legitimate interest. WooCommerce session cookies are strictly necessary for e-commerce functionality. - CCPA/CPRA: Visitor tracking via stats pixel and visitor ID cookies constitutes collection of personal information. Social embed tracking represents data sharing with social platforms.
- Automattic Privacy Policy: Automattic is a US company headquartered in San Francisco. It participates in the EU-US Data Privacy Framework and offers SCCs. Automattic's GDPR commitments are documented in their privacy policy and DPA.
Should You Block This Without Consent?
Conditional. Jetpack's security modules (Protect, Akismet) can load without consent as they serve legitimate security interests. The stats module and social sharing scripts should be blocked until analytics consent is granted. WooCommerce session cookies are strictly necessary for e-commerce and exempt from consent. Configure Jetpack to disable the stats module server-side until consent is obtained.
Is Automattic GDPR compliant?
Automattic typically loads analytics and functional trackers, which are not strictly necessary for your site to work. Under the GDPR and the ePrivacy Directive, non-essential cookies and trackers must stay blocked until a visitor gives clear opt-in consent. So Automattic can be fully GDPR compliant, but only if your site holds its scripts until consent is granted and lets visitors decline just as easily. Compliance depends on how your site loads Automattic, not on Automattic itself.
