Third Party Tracking

Third Party tracking helps you uncover the impact of third party code and tooling on performance and user experience.

View Third Party reports

You can view Third Party reports for each Snapshot. Navigate to a selected Snapshot → Third Party tab:

Third Party report showing number of third-party providers, transfer size and main thread execution time. It compares transfer size and execution time across third and first party resources. Also, it breaks down both based on categories of third parties, listing specific tools and services.

Each report will highlight the number of detected providers and how they contribute to page transfer size and JavaScript main thread execution time. You will be able to inspect which categories of tools take up most bandwidth and which providers are the worst performance offenders.

Track changes in Third Party metrics

Third Party metrics behave like any other metric tracked in Calibre. You can keep an eye on changes to third party-related metrics over time on Pulse dashboard, Pages Leaderboard or set Budgets against them.
