Why it matters
Said at Search Central Live by a community speaker: third-party systems billed per session (chat, personalisation, testing, session replay) also run when bots render pages and can cost a high-traffic site thousands of euros a month.
How to meet it
Initialise such tools on the first user interaction (click, keypress, scroll) when they add no content that needs indexing, and compare the sessions they bill with real user sessions.
How to test it
Vendor-billed session counts match analytics sessions, and a headless render of a page starts no vendor session before an interaction.
How Regensbot covers it
Decided from one URL.
An audit reads the response, the headers, the HTML, robots.txt, the sitemaps and the structured data, and the finding shows the evidence it saw.
