Tracking
What is CRO (conversion rate optimization) and the role of measurement
CRO is systematically increasing the conversion rate. It lives and dies by measurement — without reliable data you optimize blind. How measurement and CRO relate.
Measuring YouTube and video ads with server-side tracking
Video ads measure differently than search — view-through and the longer journey from view to purchase play a big role. How server-side helps measure their real impact.
Server-side tracking and A/B testing: so the results hold up
An A/B test is only as good as the data you measure the result with. When measurement loses conversions unevenly, the test misleads. How server-side gives experiments a clean basis.
What is customer lifetime value (CLV) and how to measure it
CLV is a customer's value over the whole relationship, not just the first purchase. Why it decides how much you can afford to acquire, and how to get it into measurement and ads.

How does a platform know two events belong to one person? Either by a certain identifier (deterministic) or a statistical estimate (probabilistic). What it means for accuracy.

Discount codes and coupon sites can steal the last click and claim a conversion they didn't drive. How to measure discounts so they don't skew your attribution.
Zero-party vs. first-party data: what's the difference
