What We Build

Comprehensive Conversion Engineering

01

Page Speed & Performance Tuning

Optimizing image files, deferring non-critical scripts, and optimizing layout rendering to achieve Lighthouse scores above 90.

02

A/B & Multivariate Testing

Planning and running split tests on headlines, product grids, call-to-actions, and checkout layouts using Google Optimize or VWO.

03

Checkout Flow Optimization

Streamlining checkout steps, integrating single-tap payments (Apple Pay, Google Pay), and resolving form validation errors.

04

User Behavior & Funnel Analysis

Setting up heatmaps (Hotjar), screen recordings, and event tracking (Mixpanel) to find where users drop off in the funnel.

05

Mobile UX Layout Refactoring

Adjusting navigation buttons, text sizing, and image layouts to ensure a smooth shopping experience on mobile screens.

06

Search & Merchandising Optimization

Improving site search relevancy with auto-completing suggestions and smart product filtering controls.

The Challenge

If your store is slow or hard to navigate, visitors will leave without buying.

Getting traffic to your online store is expensive. But if 98% of those visitors leave without making a purchase, your marketing budget is being wasted. Low conversion rates are often caused by hidden technical issues: slow page load speeds, layout shifts that confuse mobile users, complex checkout forms, or search bars that return irrelevant results. Guessing what to change leads to costly design updates that may not solve the problem. Quecko optimizes conversions using data. We analyze user behavior, run technical audits, perform A/B tests, and optimize page speeds to improve your store's sales performance.

FAQ

Frequently Asked Questions

To get statistically valid results from A/B testing, we recommend having at least 1,000 conversions (sales) per month. For lower-traffic stores, we focus on speed optimizations and fixing obvious user experience bugs first.

Site speed is directly linked to conversions. Research shows that e-commerce sites loading in under 2 seconds convert at double the rate of sites that take 4 seconds or longer. Lower load speeds reduce bounce rates.

If implemented poorly, yes. Some testing tools load heavy scripts that cause page layout flicker. We prevent this by writing lightweight testing code and loading scripts asynchronously to preserve site speed.

We use funnel analysis in Mixpanel/GA4 to track user journeys. We then watch screen recordings and heatmaps (Hotjar) on high-drop-off pages to understand why users are leaving.
