Direct answers to the questions readers ask most.

[What is server-side tracking in ecommerce?](https://attributionplaybook.com/answers/what-is-server-side-tracking.md)

Collecting analytics and ad events on your own server or edge infrastructure instead of through third-party browser scripts - so blockers and cookie limits cannot strip the data.

[What is the difference between attribution and analytics?](https://attributionplaybook.com/answers/attribution-vs-analytics.md)

Analytics tells you what happened on your site; attribution assigns credit for a sale across the marketing touchpoints that preceded it. You need the first to do the second.

[What is Safari ITP and why does it matter for ads?](https://attributionplaybook.com/answers/itp-explained.md)

Intelligent Tracking Prevention caps the lifetime of browser cookies - JavaScript-set cookies can expire in days. Multi-day shopping journeys break apart, so returning buyers look like new visitors and ad platforms under-count conversions.

[Do ad blockers hide real conversions from analytics?](https://attributionplaybook.com/answers/ad-blockers-conversions.md)

Yes. Visitors with blockers often never fire your analytics or ad pixels at all, so their purchases go uncounted - and these users skew toward higher-value segments.

[What is wrong with last-click attribution?](https://attributionplaybook.com/answers/last-click-problems.md)

It gives all credit to the final touchpoint, systematically overvaluing bottom-funnel channels (brand search, retargeting, direct) and undervaluing the marketing that created the demand.
