How membership works

ApplyChoose Basic or Advanced and submit this form with your work email.
ApprovalThe Secretariat reviews every application, usually within 1–3 working days.
Get set upIn your member account: confirm your website, publish your Website Trust Credential and add the CGBB Member badge.
Self-testWith the badge on your website, run the free Brand Trust Baseline self-test for an indicative score and priorities.?

How Advanced membership works

Join or upgradeAdvanced membership runs for a minimum of one year and renews yearly.
Trust ReviewCGBB checks the evidence behind all 15 indicators of the Brand Trust Baseline.
ReportYou receive the full, downloadable Trust Review report, including what to improve.
Verified TrustedAt 80% or higher, your Website Trust Credential (trust.json) is upgraded to Verified Trusted: it carries your score and is backed by the official third-party Trust Review. You also get the Verified Trusted badge.

Verified Trusted requires an active Advanced membership and a Baseline score of at least 80%, with evidence support of at least medium and no unresolved major risk. Upgrading alone does not guarantee it. If you score below 80%, your membership stays Advanced, and CGBB gives you supportive advice, based on your report, on how to reach 80%. You can take a further review once a quarter during your membership, each with a report on how to improve or maintain your rating. Referred by a Verified Trusted Advanced member? You receive one extra trust point in your Trust Review, and so does the member who referred you.

Get your CGBB Website Trust Credential and publish it at /.well-known/trust.json.
Add an llms.txt file that tells AI assistants who you are and where your key facts are.
Add schema.org Organization data to your homepage: legal name, logo, contact details and links to your official profiles.
Keep your name, address and contact details the same on your website, LinkedIn and business directories.
Allow reputable AI crawlers in your robots.txt, unless you have a reason not to.
Publish clear, factual pages AI can quote: what you do, for whom, where, and the evidence behind it.
