eCommerce Performance Optimization that Loads Fast and Converts

Speed and Core Web Vitals work for online stores: caching, image and code optimisation, database and hosting tuning, and Hyvä or headless front-end rebuilds when the theme itself is the bottleneck.

Why Indexiz

Why Indexiz for Store Performance

Speed work is easy to do badly: a plugin here, a cache there, and the numbers slide back within a month. We measure properly, fix root causes and verify the gains with real users.

Real-User Metrics

We optimise for CrUX and RUM data your customers actually experience, not just a lab score on one page.

Root Causes Fixed

We fix slow queries, bloated themes and misconfigured caches at the source rather than masking them.

Platform Specialists

Deep Magento, Shopify, BigCommerce and headless experience means we know where each platform hides its performance debt.

Gains that Last

Monitoring, budgets and a performance checklist for your developers keep the store fast after we finish.

Our approach

Measure. Fix the Biggest Thing. Repeat.

A ranked plan, fixes in sprints and real-user verification after each one, so every week of work shows up in your Core Web Vitals and your conversion rate.

FAQ

Frequently Asked Questions

Answers to the questions we hear most often. Need more detail? Talk to our team.

Most stores we work on pass Core Web Vitals on mobile within one to two sprints, with LCP improvements of two to three seconds. The audit gives a forecast per fix before you commit.

Rarely. Most gains come from caching, images, scripts and backend tuning. We recommend a Hyvä or headless rebuild only when the existing theme cannot reach your targets.

Yes. Across our projects, passing Core Web Vitals on mobile typically lifts conversion by double digits, and Google uses the same metrics as a ranking signal.

We test every change on a staging copy and run regression checks on checkout, search and integrations. Where an app is the cause of slowness we propose lighter alternatives.

We leave you with monitoring, alerts, performance budgets in your deployment pipeline and a checklist for developers, and can include periodic reviews in a support plan.
