Speed and Relevance: The Key to 14.5% More Conversions with RUMvision & Tweakwise

You invest a lot of time and money in your online store. The design looks great, your campaigns are running, SEO is on point — and yet, conversions are lagging behind. Sound familiar? Cameranu, one of the largest electronics retailers in the Netherlands, faced the same challenge. Their solution: invest in speed and relevance, resulting in a 14.5% increase in conversions. How? By combining the strengths of RUMvision and Tweakwise.

Speed without conversion is worthless. Relevance without speed is too.

A fast site that doesn’t convert won’t get you far, and a smart search solution can’t shine if the user experience is slow or unstable. It’s the combination of technical performance and intelligent personalization that creates the optimal customer journey and drives conversions. That’s exactly where RUMvision and Tweakwise reinforce each other.

Real-time Performance Insights from Real Users with RUMvision

Everyone knows speed matters. But few realize that Google’s Core Web Vitals data is 28 days old and only represents the fastest 75% of your visitors. That means you’re missing crucial insights from your slowest users, the ones with the greatest potential for improvement.
RUMvision gives you real-time insights into how your site performs for all your visitors. The tool measures Core Web Vitals such as:
  • LCP (Largest Contentful Paint) – How fast does your main content load?
  • INP (Interaction to Next Paint) – How responsive is your site?
  • CLS (Cumulative Layout Shift) – How stable is your layout?
Unlike synthetic tests, RUMvision instantly shows you the impact of changes to your site, such as a redesign, new scripts, or A/B tests. This allows you to make quick, informed adjustments and communicate internally with data to back your optimizations.

Tweakwise: Smarter Search and Conversion Than Ever Before

Once your site is fast, the second part of the challenge begins: helping visitors find what they’re looking for. Tweakwise ensures an optimal conversion flow with:
  • Intelligent search results that understand the intent behind queries
  • Personalized product listings that adapt to user behavior and preferences
  • Smart filters for intuitive navigation
  • Merchandising rules for full control over product placement
The result? More relevant results, fewer drop-offs, higher customer satisfaction, and more conversions.

Case Study: How Cameranu Achieved 14.5% More Conversions

In 2024, Cameranu underwent a complete webshop redesign. Rather than relying on assumptions, they used RUMvision to monitor real-user performance in real time. The results were striking: the LCP (Largest Contentful Paint) improved by 26.9%, dropping from 2357ms to 1722ms.
The visual stability (CLS) of the homepage improved dramatically by 95.3%, while both UX and FUX scores (user experience and first-user experience) showed significant gains. Thanks to RUMvision’s annotation feature, Cameranu was able to clearly map trends before and after the redesign and optimize with precision.
At the same time, they worked on boosting relevance with Tweakwise. By implementing smarter search results, personalized product listings that adapt to user behavior, and data-driven merchandising, they refined the online experience and aligned it closely with visitor needs.
This combined approach led to an impressive 14.5% increase in conversions within six months.

Guided Selling: Making Product Discovery Fun and Human

Guided Selling is one of Tweakwise’s standout features. Based on product attributes, you can create intuitive, human-like questions that help visitors narrow down large assortments. Think “How big is your plant?” instead of “Which pot diameter are you looking for?” This removes the need for dozens of filters and turns shopping into a smoother, more enjoyable experience, a smart and engaging way to enhance product discovery.

Why You Need This Combination Too

You can invest endlessly in ads, branding, and visuals, but if your site is slow or shows irrelevant products, your customers will still leave. The combination of RUMvision and Tweakwise gives you the insights and tools to improve instantly:
  • See where visitors drop off
  • Understand why it happens
  • Fix it immediately
That’s how you take full control of the entire user experience, from the first click to the final conversion.
