Powered by GRTforms badge
Free public forms show a small badge that links back to GRTforms. Paid plans remove it. Click-throughs are attributed to the form.
Who sees it
Respondents on a free-plan form see the badge under the form and on the in-page thank-you, including custom success copy. Iframe and JavaScript embeds use the same hosted page, so the badge is there too. Paid plans hide it. A thank-you that redirects to another URL leaves GRTforms, so there is no badge on that destination.
Preview in the builder matches the owner's plan. There is no form setting to hide the badge on a free plan.
The link
The badge opens the GRTforms landing page in a new tab with utm_source=badge, utm_medium=form, utm_campaign=powered_by, and the form's public slug as form_id.
