Definition

A method of comparing two versions of a feature or UI to determine which one performs better with real users.

طريقة لمقارنة نسختين من ميزة أو واجهة مستخدم لتحديد أيهما أداؤه أفضل مع المستخدمين الحقيقيين.

Why It Matters

Before redesigning the 404Fault glossary layout or learning dashboard, A/B testing could validate whether a change actually improves engagement rather than just looking nicer.

قبل إعادة تصميم تخطيط قاموس 404Fault أو لوحة التعلم، يمكن لاختبار A/B التحقق من أن التغيير يُحسّن المشاركة فعلًا بدلاً من مجرد البدو أجمل.

Full Definition

A/B testing randomly splits users into groups (A = control, B = variant) and measures which version achieves the goal better (higher click rate, longer session, more conversions). Statistical significance ensures results aren't random. Next.js Middleware can implement routing-level A/B tests. Vercel Edge Config integrates with feature flag tools. For a SaaS in early stages, qualitative user interviews often give better insight than A/B tests.
اختبار A/B يقسّم المستخدمين عشوائيًا إلى مجموعات (A = التحكم، B = البديل) ويقيس أي نسخة تحقق الهدف بشكل أفضل. وسيط Next.js يمكنه تنفيذ اختبارات A/B على مستوى التوجيه.

Example Usage

“// Middleware A/B routing: const variant = Math.random() > 0.5 ? 'a' : 'b'; res.cookies.set('variant', variant); return NextResponse.rewrite(`/glossary-${variant}`);”

“// توجيه A/B بالوسيط: const variant = Math.random() > 0.5 ? 'a' : 'b'; res.cookies.set('variant', variant); return NextResponse.rewrite(`/glossary-${variant}`);”

Avoid these mistakes when using A/B Testing:

1

Running tests with too few users — results won't be statistically significant

2

Testing multiple changes at once — you won't know which change caused the improvement
