The SDK's attribution badge, and how its referrals stay measurable.
Updated
Client sites built on a platform's site SDK can carry a small "powered by" badge crediting the platform. The SDK injects it after the page is interactive — scheduled via requestIdleCallback (with a timeout fallback), waiting for DOM readiness — so it never competes with the site's own content for load time.
The badge's link is UTM-tagged with the client site's own hostname:
https://<platform-domain>/?utm_source=<client-site-host>
&utm_medium=referral
&utm_campaign=powered_by
&utm_content=sdk-badge
so referrals from each site are attributable in the platform's own analytics — the badge is a measurable acquisition channel, not just decoration.
The tag uses the hostname only, never the full URL — no paths or query strings from the host page leak into the referral link.
