Buffer - Social Sharing Cookie Management

Back to Vendor Library

Overview

Buffer is a social media management platform used by marketing teams and content creators to schedule, publish, and analyze social media posts. On third-party websites, Buffer's presence is typically limited to social sharing buttons and referral attribution scripts that track traffic arriving from shared social posts. Buffer's browser footprint is lighter than most marketing platforms, but its tracking of referral traffic and social engagement metrics places it in the marketing category.

What This Script Does

Buffer may load scripts on websites in two scenarios: social sharing button widgets and referral tracking from Buffer-shortened links.

Social sharing widgets:

Render share buttons for platforms like Twitter/X, LinkedIn, Facebook, and Pinterest
Track share counts and click-through rates on shared content
Load from bufferapp.com or buffer.com subdomains

Referral attribution:

UTM parameters and referral data from Buffer-shortened URLs are tracked on landing pages
Cookies store the referral source to attribute conversions to specific social posts

Cookies set:

_buffer_session — session cookie for widget state management
Referral attribution cookies that persist across the session to tie conversions to social campaigns
Minimal persistent storage compared to full marketing automation platforms

Buffer's data collection is focused on measuring social media ROI rather than building detailed visitor profiles. However, the referral tracking and conversion attribution functionality means it processes visitor data for marketing measurement purposes.

Consent & Compliance

Buffer's tracking falls under the marketing consent category. Under GDPR, the referral tracking cookies and social sharing analytics require consent before loading, as they are not strictly necessary for the website's functionality. The social sharing buttons themselves load third-party scripts that may set additional cookies.

Under CCPA/CPRA, Buffer's referral attribution data collection should be disclosed in the site's privacy policy. If Buffer shares aggregated engagement data back to the site operator for marketing optimization, this processing should be covered by appropriate disclosures.

Should You Block This Without Consent?

Yes. Buffer scripts track social referral traffic and sharing engagement for marketing analytics purposes. While lighter than full marketing automation tools, the referral attribution cookies and social tracking require opt-in consent under GDPR and appropriate disclosure under CCPA.

Is Buffer GDPR compliant?

Buffer typically loads marketing 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 Buffer 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 Buffer, not on Buffer itself.
