A/B and Multivariate Testing

  1. A/B Testing (or split testing): compares two versions of a page. Version A and version B, to determine which performs better;
  2. Multivariate testing: takes A/B testing a step further by comparing multiple elements and their combinations at once.
Note
Note

Multivariate testing is best for high-traffic websites or apps. If your site has fewer visitors, results may not be conclusive.

Heatmaps and User Recordings

Analytics show how many people bounced; recordings show why they did.

Heatmaps

They reveal hot zones (areas with heavy user activity) and cold zones (elements users ignore).

User Recordings

Or session replays show real visitors navigating your site β€” mouse movements, clicks, scrolls, and hesitations.

Personalization Techniques

Personalization means tailoring content, offers, or messages to individual users based on their location, behavior, or interaction history. It transforms your landing pages from "a page" into "my page".

  • Location & time-based personalization;
  • Visitor-type personalization;
  • Behavioral personalization.

Personalization builds trust only when it's done with respect. Avoid crossing the line from "relevant" to "creepy".

Optimizing for Mobile and Speed

Speed is the New Currency

Users expect instant loading. If your page takes more than 3 seconds, most visitors will leave β€” and every second longer cuts conversion rates dramatically. Problems:

  • Oversized Images: cause slower loading. Compress images;
  • Heavy Scripts: blocks rendering. Remove or defer scripts;
  • Slow Hosting: delayed response. Upgrade to quality hosting;
  • Auto-Playing Media: consumes bandwidth; Use lazy loading.

Designing Mobile-First

Designing for mobile isn't about shrinking a desktop layout β€” it's about rethinking the entire experience for small screens. Best practices:

  • Use large, tappable buttons;
  • Keep forms short (2–3 fields);
  • Stack content vertically;
  • Make text legible without zoom;
  • Test across devices.

Thumb-Friendly Interaction

Mobile users scroll with one hand β€” usually their thumb. That means CTA placement matters as much as the message.

Iterative Improvement

The iterative CRO process follows a simple, repeatable cycle.

The CRO Loop Steps

  2. Find friction points;
  3. Form a hypothesis;
