Answers to common questions about Keak and its features.

Keak works with virtually any website — HTML/CSS/JS, Next.js, React, Vue.js, Angular, Svelte, Astro, Remix, Vite, and Gatsby for JS frameworks, plus Shopify, WordPress, Webflow, Squarespace, Wix, and Framer for no-code platforms. The tracking pixel supports websites in 100+ languages, and you can target visitors by browser locale for market-specific testing.
No — the Keak pixel is ~31KB gzipped, loads asynchronously (never blocks rendering), and has minimal impact on Core Web Vitals. An anti-flicker overlay prevents content flash (protecting your CLS score), and our SPRT-based statistics engine runs server-side. Variants are applied in under 100ms with zero layout shift.
Keak integrates anywhere you can add a JavaScript snippet to the <head> of your page. That covers all major JS frameworks (Next.js, React, Vue, Angular, Svelte, Astro, Remix), no-code builders (Shopify, WordPress, Webflow, Squarespace, Wix, Framer), and plain HTML sites. We provide platform-specific installation guides for every supported platform.
Yes. Keak provides a REST API for programmatic access — create tests, retrieve results, manage variations, and trigger webhooks. API access is available on the Pro and Enterprise plans. You can also configure webhooks to receive real-time notifications when a test reaches significance, a winner is declared, or traffic thresholds are hit.
Keak uses usage-based pricing. You pay $0.005 per impression, with no monthly subscription and no seats. Free accounts can build and preview variants without a card, and get 25 variants, 3 image variants, and 1 domain per month. Tests don't serve traffic until you add a payment method; once you do, variants, images, and videos all become unlimited, and you only pay $0.005 per impression for what you actually serve. Enterprise is fully custom, with volume discounts, a dedicated account manager, API access, and commercial SLAs.
Keak optimizes the landing pages your ads send traffic to, not the ad creatives themselves. You can A/B test headlines, CTAs, layouts, and copy on any landing page, then measure conversion uplift directly from ad traffic. This means your ad spend goes further — the same budget, but significantly better page performance. For ad creative testing, use your ad platform's native tools alongside Keak.
