Why this matters
Every service = bytes, requests, and main-thread CPU.
Fewer services = faster pages = more conversions.
Cadence
Ad-hoc snapshots (manually appended)
New row when audit is re-run or a major change ships.

How to read this. Each row represents one complete audit of what loads on the site. "Services" counts distinct third-party vendors/domains. "Transfer" is total bytes downloaded; "Main-thread CPU" is total time the browser spent parsing/executing those scripts — both at the time of the run. The "vs. prev run" column shows how many services were added and removed since the previous audit. Numbers in parentheses like (11/21) mean only 11 of 21 services had that metric captured — early audits were often partial.
