Conversion Tracking helps you improve the return on investment (ROI) from your online advertising because it:
Correct Answer
shows you which ads lead to customer actions that have value for your business
Why is this the correct answer?
Conversion Tracking helps improve ROI from online advertising because it shows you which ads lead to customer actions that have value for your business. By tracking specific actions — purchases, form submissions, phone calls, app downloads — conversion tracking connects ad spend directly to business outcomes. This data reveals which campaigns, keywords, and ads are generating real value and which are wasting budget on clicks that never convert, enabling data-driven optimisation that improves ROI over time.
Why are the other options incorrect?
measures trends relating to the search terms people have used before seeing your ad
Search Terms reports measure which queries trigger ads — useful for keyword management but not directly tied to measuring which ads produce valuable customer actions.
focuses on getting customers to complete an online purchase
Conversion tracking can track any defined action, not just online purchases. Limiting it to purchases ignores the broader range of valuable business actions it can measure.
automatically gives you personal details about the people who convert
Conversion tracking does not provide personal details about converters — it records anonymised conversion events tied to campaigns and keywords, not personal user data.
Real-World Example
A B2B software company implements conversion tracking for demo requests, free trials, and pricing page visits. They discover their Display ads generate high click volume but zero demo requests, while Search ads drive 90% of conversions at a fraction of the Display cost. They reallocate 70% of budget to Search, reducing cost per demo request by 55%.
