Does Ghost have a built-in cookie banner?

No. Ghost focuses on publishing and members but doesn't ship a cookie consent banner. For GDPR compliance with GA4, Meta Pixel, or any other tracker you need to add a CMP via Code Injection.

Will it work with Ghost Members and portal modals?

Yes. The CookieBoss banner renders in a closed Shadow DOM at the highest z-index, so it stays above Ghost's portal modals and doesn't interfere with member signup or subscription flows.

Where do I paste the script in Ghost?

Ghost Admin → Settings → Code Injection → Site Header. Save. The banner loads on every page including the homepage, posts, pages, and member areas.

Why CookieBoss for Ghost

Ghost doesn't ship a CMP

Built-in members, themes, and SEO — but no cookie consent banner. CookieBoss fills the gap without breaking Ghost's perf budget.

Works with Ghost Members

Banner renders at the right z-index above Ghost's portal modals. Members signup, subscription, and tier upgrade flows are untouched.

Knows your trackers

Auto-detects GA4, Meta Pixel, Plausible, Fathom, and Mailgun/SendGrid analytics cookies common in Ghost publications.

GCM v2 for newsletter ads

If you run Google Ads to promote your newsletter, GCM v2 fires before gtag.js so your conversion attribution stays intact.

Shadow DOM isolation

Banner styles can't conflict with your Ghost theme — even custom-built themes.

Edge-compiled, under 25KB

Won't undo the perf work Ghost does. Lighter than most Ghost theme assets.
