A/B Testing Without Cookies
Optimize Landing Pages Without Slowing Them Down.
What Is Cookieless A/B Testing?
A/B testing (also known as split testing) helps you compare different landing page versions to see which one converts better. But traditional A/B testing tools rely on JavaScript, third-party cookies, and client-side tracking, which slow down your page, require cookie consent, and create GDPR issues.
With Blueprint’s server-side, cookieless A/B testing, you get real-time testing without the bloat—no extra scripts, no tracking pixels, no compliance headaches.
Why Use Blueprint’s A/B Testing?
✅ Faster Pages = Higher Conversions – No heavy JavaScript or third-party tracking scripts slowing down your site.
🔒 100% GDPR-Compliant – No cookies, no personal data storage, no need for consent banners.
⚡ Server-Side Execution – Variations are served instantly without flickering or layout shifts.
📊 Accurate Results – No ad blockers interfering with tracking, no lost data from cookie rejection.
The Problem With Traditional A/B Testing Tools
Most A/B testing tools modify the page in the browser using JavaScript. This causes:
❌ Page load delays – Additional scripts and tracking pixels slow down performance.
❌ SEO risks – Google may index the wrong version of your page due to client-side modifications.
❌ Cookie consent issues – Visitors may reject cookies, leading to incomplete test data.
❌ Ad blocker interference – Many tracking scripts are blocked, making results unreliable.
Blueprint solves all of this with cookieless, server-side testing.
How Does Blueprint’s A/B Testing Work?
Instead of modifying the page in the visitor’s browser, Blueprint serves pre-rendered variations directly from the server.
Step 1
1️⃣ Create a landing page inside Blueprint and navigate to A/B Testing on the left side panel and create a name.
Step 2
2️⃣ Make changes on your (B) variation. When you're ready - click "Start A/B Test" on the top right.
Steps 3, 4, 5
3️⃣ Traffic is split at the server level—visitors instantly see their assigned variation.
4️⃣ Track performance with real-time analytics (conversion rate, time on page, etc.).
5️⃣ Automatically declare a winner or manually adjust based on results.
How & Why Cookieless / Server-side A/B Testing Works
Traditional A/B testing tools modify pages in the visitor’s browser using JavaScript. This can slow down load times, cause layout flickering, and even create SEO issues if Google indexes the wrong version.
Blueprint bypasses all of that by handling A/B testing at the server level. Here’s how it works:
1️⃣ User requests a page → Blueprint’s server instantly determines which variation to serve.
2️⃣ Pre-rendered page is delivered → No scripts or client-side modifications are needed.
3️⃣ No tracking scripts, no cookies → No extra load time, no compliance issues, no flicker.
4️⃣ Real-time performance tracking → Monitor conversions and declare winners effortlessly.
💡 Because everything happens before the page even loads, your visitors get the fastest, most seamless experience—without tracking issues, consent banners, or SEO risks.
Every extra second of load time kills conversions. Since Blueprint’s A/B testing has zero impact on performance, you get more sales, leads, and sign-ups without slowing things down.
If you’re running landing pages in Europe, UK, or any region with strict privacy laws, Blueprint’s cookieless testing eliminates GDPR, CCPA, and privacy compliance headaches.
Since Blueprint doesn’t use JavaScript-based tracking, ad blockers can’t block your A/B tests—ensuring you get complete and accurate test results.
Client-side A/B testing tools can cause SEO indexing issues and slow down your PPC landing pages. Blueprint’s server-side approach ensures Google sees the correct version and your ads load instantly.
