Introductie

Do you want to know if your online ads are really delivering results? Many SMEs invest in online marketing but lack insight into what actually generates revenue or leads. With conversion tracking, you see exactly which customer actions result from your ads. This allows you to make data-driven decisions, allocate your budget more intelligently, and demonstrably increase your return on marketing.

Definition: What is conversion tracking?

Conversion tracking is a marketing technique that allows companies to measure user actions—such as purchases, sign-ups, or completed contact forms—after online advertisements. Tools like Google Analytics, Facebook Pixel, or LinkedIn Insight Tag record these conversions, giving marketers insight into their campaign performance and opportunities to implement targeted optimizations.
