6 languages + geolocation The banner shows in the visitor's language with per-country geolocation, server-side.

Before / After

Why most banners don't truly comply and what makes Consentio different.

Before

  • Most free banners show the notice but do NOT block scripts before consent (breaching GDPR).
  • Paid ones are heavy and hurt SEO and Core Web Vitals.
  • Complex setup for every CMS or platform.
  • No solid proof of consent for an audit.
  • No real Google Consent Mode v2 support or GPC signal handling.

After

  • Real script blocking: no tracker runs before consent.
  • Full Consent Mode v2, with signals denied by default.
  • A script under 9 KB, dependency-free and deferred.
  • Multi-language (6) with per-country geolocation and multi-region (GDPR opt-in in the EU / "Do Not Sell" opt-out in the US).
  • Cookie scanner, consent record/proof and GPC signal support.

Architecture

A logical view of the flow. The snippet blocks by default, server-side geolocation decides region and language, and only after consent are the Consent Mode v2 signals updated and the providers unblocked.

Consentio architecture The visitor loads the client's website, which embeds the Consentio snippet. The snippet blocks trackers by default and shows the banner. Server-side geolocation decides region and language without storing the IP. On consent, Consent Mode v2 signals are updated towards GTM/Google and the proof of consent is recorded on EU servers.

Solid line: main flow. Dashed line: subscription sign-up by the website owner.

Technical decisions (and why)

The details that separate a banner that "shows up" from one that truly complies and doesn't penalise the site.

Performance

Performance is a requirement, not an extra

A consent banner loads on every page, so every kilobyte counts. The script is dependency-free, weighs under 9 KB and defers loading pixels and trackers until consent. Deferring those scripts improves Core Web Vitals: compliance is no longer at odds with SEO.

Compliance

Real script blocking, not just a notice

The legal difference is in actually blocking. Before consent, no tracker runs; a cookie scanner and auto-blocking of known providers prevent leaks. Google Consent Mode v2 starts with all four signals denied by default and is updated only when the visitor accepts.

Privacy

Geolocation on our own server, without sharing the IP

Region and language are decided with server-side geolocation, with no external services: the visitor's IP is neither shared nor stored. True multi-region: GDPR-style opt-in in the EU and CCPA-style "Do Not Sell" opt-out in the US, also honouring the browser's GPC signal.

Traceability

Consent record and proof

Every decision is logged with country, language and the version of the text shown, on EU servers. In an audit, there's demonstrable proof of what each visitor accepted and under which version, not a promise. Data lives in the EU by design.

Distribution

One universal snippet, plus plugin and GTM template

Integration is deliberately simple: a universal snippet for Shopify, Wix, Webflow, Squarespace or PrestaShop; a WordPress plugin; and a Google Tag Manager template. The same consent logic, installed where the client already works.
