Overview
Contextual advertising platform that analyses page content in real time to serve relevant ads without relying on third-party cookies. Seedtag's JavaScript tag reads the page DOM to understand content context and places in-content advertising units. While marketed as a privacy-first alternative to behavioural targeting, the tag still processes page data and makes network requests to Seedtag servers, which requires assessment under GDPR and the ePrivacy Directive.

Common mistakes
- 1Deploying Seedtag contextual advertising tags without consent because the vendor markets itself as cookieless and privacy-friendly, when the tag still processes page content and may collect device identifiers
- 2Not including Seedtag in the CMP advertising category because contextual targeting is perceived as not requiring consent, despite the tag making network requests that transmit page URL and content data
- 3Failing to audit what data Seedtag collects from the page context, including article text and metadata that may be used for audience segmentation beyond simple contextual matching
- 4Overlooking Seedtag's in-content ad placement which modifies the DOM and may affect page layout and accessibility
Compliance considerations
Seedtag's contextual approach avoids third-party cookies and cross-site tracking, but the tag still accesses the page DOM to analyse content and transmits contextual signals to Seedtag servers. Under the ePrivacy Directive, accessing and transmitting information from the user's terminal equipment may require consent depending on jurisdiction and interpretation. Seedtag is a Spanish company headquartered in Madrid, which simplifies data residency for European organisations. The tag should be included in the CMP under the advertising category and blocked until appropriate consent is granted. Organisations should verify Seedtag's IAB TCF registration and ensure their data processing agreement covers the specific data flows from page content analysis.
