CDP Documentation Index

How it’s scored

On November 6, 2026, CdpHub requested each of the 6,314 distinct pages once, with its own user agent (CdpHub-DocsCheck/1.0), one request at a time per site and at least two seconds apart, following redirects and respecting robots.txt. Main text was measured without menus and page furniture. Pages a site’s robots.txt closes to automated readers weren’t requested and count as turned away, and so do a site’s other pages once it has refused the first five requests. Page text isn’t kept or published, only the measurements.

The score is about public documentation as an automated reader receives it, not about product quality, support or docs behind a login. A page that shows its text only after scripts run may read fine in a browser, but many AI crawlers and assistants don’t run scripts, so it counts as not readable here.

Coming in part two

The other 60 points score what each readable page says, so a long page that leaves out the essentials doesn’t score well:

• Setup steps: how to connect it
• Direction and data: what moves, and which way
• Access: the account, key, permission or plan needed
• Fields: what maps to what
• Limits: rate limits, volumes, sync frequency
• A date from the past 12 months
• Troubleshooting: what goes wrong

Each answer is backed by an exact phrase found on the page. With both parts in, every CDP with enough pages read gets a grade from A to D.

Vendors: if your docs have changed or a figure looks wrong, ask for a re-check at ed@cdphub.com. CdpHub is independent and takes no referral fees or vendor commissions.
