How Laserhub Improved Their Click on CTA Conversion Rate by 40% with Nelio A/B Testing.
The Company

Laserhub is an online procurement platform for custom metal and synthetic parts. They streamline the process of ordering sheet, bending and CNC components by offering its customers access to a large network of producers. Laserhub is always the single point of contact, which simplifies logistics for customers. Their goal is to digitize and simplify metal production procurement, saving companies time and effort.
Their website is divided into two main areas: the platform and the marketing site. The product team focuses on the platform, ensuring customers can easily calculate and order components. Meanwhile, the marketing team manages the marketing site, aiming to clearly and quickly communicate what Laserhub offers and how it stands out from competitors. A key performance metric for them is the visitor-to-signup conversion rate.
The Challenge
Laserhub noticed that a significant number of visitors were dropping off before doing a signup. They needed a way to test different page elements to understand what was causing hesitation and optimize for higher conversions and engagement.
Their primary goal was to drive website visitors to the platform, where they can calculate and order custom components. The main success metric is platform registrations, as only registered users can make purchases. In the long run, they also track customer lifetime value to measure overall business impact.
The Solution

Laserhub’s website runs on WordPress, so they needed a tool that was easy to use and fully compatible with the platform.
What makes Nelio A/B Testing stand out is its seamless integration. When creating an A/B test, Nelio automatically generates a test page and serves it to visitors—without cluttering the Pages section in WordPress. This keeps everything organized and streamlined, preventing unnecessary complexity.
A/B Testing Setup
One of Laserhub’s main goals with testing was to answer the following question:
- What information do users want in the hero area when they open the different product pages?
They began by using heatmaps and clickmaps to analyze user behavior on different product pages, identifying which areas attracted the most attention.


Within this analysis, they carried out several A/B tests on different product pages changing headers, images, and buttons.


✨ Key Features Used
- Heatmaps, scrollmaps, and clickmaps to undertstand user behavior
- Page A/B Testing. This way they could simply build new variants of the site and test them against each other. Their main focus was to improve the conversion rate of their main call to actions:
- Headline variations to emphasize cost savings and speed.
- CTA button text to make the action more compelling.
🔧 Implementation Process
- They regularly tested the above-the-fold content on various pages to determine what information was most important to visitors. Key questions they explored included:
- What details do visitors want to see first?
- Are they interested in the dimensions of metal parts?
- Do they want to know which materials are available?
- Is delivery time a top priority for them?
