Amazon Ads

Advertising

High · Amazon Ads

Advertising pixel that sends conversion and browsing data to Amazon's demand-side platform, where it can be combined with Amazon's extensive first-party consumer purchase data. Supports audience building and retargeting across both Amazon-owned properties and third-party publisher networks. The tag's integration with Amazon's vast consumer data ecosystem raises significant governance questions about data enrichment and cross-context profiling that DPOs in regulated organisations should assess carefully.

Bidr (RhythmOne)

Advertising

High · Bidr (RhythmOne)

Cookie-syncing and identity resolution domain (operated by Nexxen, formerly Tremor International) that frequently appears in tag audits without the website operator having deployed it directly. Arrives via programmatic ad supply chains, header bidding wrappers, and third-party pixels, synchronising user identifiers across multiple advertising platforms. One of the most commonly flagged third-party tracking domains in European cookie audits, and a strong indicator that the organisation's ad supply chain requires closer governance scrutiny.

Flashtalking

Advertising

High · Flashtalking

Ad serving and conversion tracking tag (rebranded to Innovid following the Mediaocean merger in February 2025) that delivers creative assets, tracks impressions and clicks, and collects conversion data across publisher websites. Typically deployed through agency relationships rather than directly by the website operator, making it less visible to governance teams. Includes identity resolution capabilities that link user interactions across devices and channels, raising cross-device tracking concerns for DPOs.

LinkedIn Insight Tag

Advertising

High · LinkedIn Insight Tag

Particularly sensitive advertising tag because it effectively de-anonymises website visitors by linking browsing behaviour to identified LinkedIn member profiles. Collects page visit data and cross-references it with LinkedIn's professional identity graph, associating visits with job title, company, and industry attributes. Widely deployed on B2B and career pages, often without adequate recognition that this tag converts anonymous browsing into identified professional profiling.

High · Meta

Meta's advertising tag for tracking user actions and sending conversion data to Facebook, Instagram, and WhatsApp. Enables retargeting, lookalike audiences, and conversion measurement.

Microsoft Ads (UET)

Advertising

High · Microsoft Ads (UET)

Advertising tag that tracks browsing behaviour and sends conversion data to Microsoft's ad platform, covering the Bing, Yahoo, and DuckDuckGo syndicated search network. Frequently deployed alongside Google Ads tags but receives significantly less governance attention despite collecting comparable data. Commonly found on regulated organisation websites due to Microsoft's broad enterprise presence, making it a frequent oversight in tag audits that focus primarily on Google and Meta pixels.

Publisher consortium advertising tag (News UK, The Guardian, Reach) that facilitates audience targeting, impression tracking, and conversion measurement across participating UK and European publisher websites.

Pinterest Tag

Advertising

High · Pinterest Tag

Advertising pixel that tracks page visits, sign-ups, and purchases, sending conversion data to Pinterest's US-based ad platform for retargeting and audience creation. Lower profile than Meta or Google advertising tags, which means it is frequently overlooked during governance audits despite collecting comparable browsing and conversion data. Enhanced Match functionality can transmit hashed personal data, which should be disclosed in the organisation's privacy notice.

Podscribe

Advertising

High · Podscribe

Podcast attribution pixel that cross-references website visit data with podcast listening data, linking user behaviour across two distinct media channels. This cross-channel matching creates a particularly complex data flow for governance review. Primarily US-focused with potentially less mature GDPR compliance infrastructure than larger advertising platforms, so DPOs should scrutinise data processing arrangements carefully before deployment.

Reddit Pixel

Advertising

High · Reddit Pixel

Advertising pixel that tracks page visits, sign-ups, and purchases, sending conversion data to Reddit's US-based ad platform for retargeting and campaign optimisation. Less widely deployed than major platform pixels, which means it is frequently overlooked during tag governance audits. Increasingly found on technology, gaming, and financial services websites, and its lower profile should not be mistaken for lower risk.

High · Seedtag

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.

TikTok Pixel

High · TikTok Pixel

High-scrutiny advertising pixel due to ByteDance's Chinese ownership and the potential for data access by Chinese authorities under national security legislation. Tracks page views, add-to-cart actions, and purchases, sending conversion data to TikTok's ad platform. Multiple EU member states have restricted TikTok on government devices, and European DPAs have raised specific concerns about data transfers. Deploying this tag on a regulated organisation's website requires careful risk assessment beyond standard advertising tag governance.

YouTube

Advertising

High · YouTube

Among the most common third-party tracking findings in tag governance audits. Standard YouTube embeds set cookies and transmit data to Google's advertising infrastructure even when the visitor does not interact with the video. The privacy-enhanced mode (youtube-nocookie.com) defers some cookie setting but does not eliminate data collection, and is frequently misunderstood as a complete privacy solution. Multiple European DPAs have confirmed that standard YouTube embeds require consent under the ePrivacy Directive.
