The Quora Pixel is the conversion tracking and remarketing pixel for Quora Ads, the advertising platform of the Q&A community Quora.com.
The Quora Pixel is the JavaScript tracking snippet that advertisers add to their website to measure conversions from Quora Ads, the advertising platform of the Q&A community Quora.com. Quora Ads runs sponsored answers, image ads and lead generation forms targeting users by topic, keyword and audience. The pixel measures purchases, sign ups, downloads and other conversion events, and feeds remarketing audiences back into the Quora Ads Manager.
The Quora Pixel drops third party cookies on quora.com (m-b, m-s, m-uid as the user identifier, qcl_* helpers) and reads a first party identifier on the advertiser domain. On every page view it sends the URL, the referrer, event names (Generic, ViewContent, Purchase, Lead) and custom parameters (value, currency, content_ids). The Quora Conversions API allows server side delivery of the same events, optionally with hashed email or phone for matching.
The Quora Pixel is a third party advertising tracker. Article 5(3) ePrivacy and article 6 GDPR require prior, opt in consent before the pixel can fire in identified mode. Quora and the advertiser are joint controllers for the audience targeting and conversion measurement processing. Treat the Conversions API the same way as the client side pixel: server side processing does not exempt from consent.

Block the Quora Pixel inside your CMP until consent is granted for Marketing. Quora supports the IAB TCF v2.2 signal: forward the TC string so the pixel only processes data for vendors with valid consent. For the Conversions API, send events only for users who have consented. Limit retention of custom audiences and avoid uploading sensitive personal data.
Quora Inc. is based in California and processes Quora Pixel data on US infrastructure. Transfers rely on EU SCCs and on the EU US Data Privacy Framework when Quora Inc. is certified. Document the transfer mechanism in your records of processing activities and inform users in your privacy notice.
Sign the Quora DPA with EU SCCs. Wrap the pixel in a consent gate. Forward the IAB TCF v2.2 string. Restrict Conversions API events to consenting users. Limit custom audience retention.

DPIA considerations
A DPIA is recommended whenever the Quora Pixel is used for large scale remarketing, when Conversions API transmits hashed identifiers, when custom audiences are uploaded from a CRM, or when advertising targets sensitive verticals.
