Conversion tracking is the direct link between your marketing spend and measurable business outcomes. Without accurate conversion signals, automated bidding strategies operate on incomplete data, budget allocation decisions are made on guesswork, and attribution reporting misrepresents the value of every channel. Hellenic Technologies implements conversion tracking across all major advertising platforms, with a focus on signal quality, deduplication, and GDPR-compliant data handling. Our conversion setups are designed to feed smart bidding algorithms with the highest quality signals available, improving campaign performance while maintaining full compliance. Conversion tracking platforms we implement:
  • Google Ads — Enhanced Conversions — Enhanced conversions send hashed first-party customer data (email, phone, address) alongside standard conversion events. This significantly improves conversion matching rates, particularly for Safari and Firefox users where cookie-based attribution is restricted. Enhanced conversions for web are implemented via GTM, and enhanced conversions for leads via the GA4 integration.
  • Google Ads — Smart Bidding Signals — GA4 conversion events are imported into Google Ads and configured as primary conversion actions for Target CPA and Target ROAS bid strategies. We audit conversion action settings to ensure value rules, attribution models, and counting methods are aligned with campaign objectives.
  • Meta Conversions API (CAPI) — Server-side Meta event forwarding via the Conversions API reduces dependency on the browser pixel, improves event match quality scores, and maintains conversion visibility despite browser restrictions and ad blockers. We implement CAPI in parallel with the browser pixel with deduplication via event IDs.
  • LinkedIn Insight Tag — LinkedIn Insight Tag deployment via GTM, including conversion event configuration for lead generation and content download goals. Matched Audiences setup for website retargeting.
  • Microsoft/Bing Ads — UET tag implementation and conversion goal configuration for clients running search campaigns on Microsoft Advertising.
What good conversion tracking looks like:
  • Every conversion action has a defined value, counting method, and attribution window
  • Server-side and browser-side events are deduplicated to prevent double-counting
  • Consent mode is respected — modelled conversions activate for non-consenting users
  • Conversion data is validated monthly against CRM and transaction records
