Wix Speed Optimization Agency for Businesses and Online Stores
App, Velo code, and media delivery optimization, engineered to speed up your Wix site and lift conversions.
Wix manages your hosting, but most of the speed is still on the table. Heavy apps stacking up, render-blocking Velo code, oversized images, and third-party scripts all drag down your site. Our Wix speed optimization service audits every app and custom code block, removes the dead weight, and tunes media and script delivery so your site loads fast and converts more visitors.
Trusted by leading brands
Our Expertise
Most one-click Wix speed apps just add another script to a slow site. We don't. Every engagement is run by a Wix speed optimization expert who profiles your site at the code level: every installed app, Velo route, image, gallery, and third-party widget. Then we cut what is not earning its place and tune the rest.
Business owners and online stores come to us as their Wix speed optimization partner because we show our work. You get a ranked app-impact report, before and after Core Web Vitals data, and documentation of every change, not a black box.

Who This Is For
Service businesses need fast-loading pages to capture leads before visitors bounce. Your contact page, service pages, and booking flow need to load in under 2 seconds.
Wix e-commerce stores need fast product pages, smooth checkout, and optimized galleries to maximize conversion rates and reduce cart abandonment.
Creative portfolios with heavy image galleries and video content need optimized media delivery to showcase work without sacrificing load speed.
Content-heavy Wix sites need fast page loads for SEO rankings, reader retention, and ad revenue optimization across hundreds of pages.
Common Problems
Every installed Wix app injects JavaScript, CSS, and API calls into your pages. Review widgets, chat tools, social feeds, and analytics apps compound into 2–4 seconds of extra load time, even when visitors never interact with them.
Guide: Why Is Wix So SlowLarge hero images, product galleries, and background videos account for 60%+ of page weight on most Wix sites. Without proper sizing, format optimization, and lazy loading configuration, media alone kills your PageSpeed score.
Custom Velo (formerly Corvid) code with excessive API calls, DOM manipulation, and unoptimized data queries adds JavaScript execution time that blocks interactivity. Poorly structured Velo code is a leading cause of high INP on Wix sites.
External chat widgets, tracking pixels, social embeds, and marketing tools loaded via HTML embeds or Velo bypass Wix's optimization pipeline entirely, creating render-blocking bottlenecks that tank both LCP and INP.
Our Solutions
We work on your Wix site safely, never breaking what already works. We audit and trim apps, refactor Velo code, optimize image and script delivery, and fix Core Web Vitals on your key pages. Here is what that covers:
We profile every installed Wix app individually for JavaScript weight, API overhead, and render-blocking behavior. You get a ranked report showing exactly which apps cost the most speed, with vetted lighter alternatives and removal recommendations.
We optimize every image and video on your site, proper dimensions, modern formats, responsive variants, lazy loading configuration, and gallery lightbox tuning. Your media looks identical but loads dramatically faster.
We audit all custom Velo code for API call efficiency, DOM manipulation overhead, data binding optimization, and execution timing. You receive specific refactoring recommendations with before/after performance measurements.
We implement strategic loading for external scripts, deferring chat widgets, analytics, social embeds, and marketing tools until after the page is interactive. Critical scripts load first; everything else waits.
We target LCP, INP, and CLS individually, fixing layout shifts from dynamic content, optimizing interaction handlers, and tuning above-the-fold rendering until all three metrics pass Google's 28-day rolling window.
We audit page sections for excessive animations, hidden elements that still render, strip composition layers, and optimize section loading order for faster perceived performance.
The Data
On a Wix site, speed is user experience and conversion rate. When you improve Wix site speed, faster pages keep visitors engaged, lift organic traffic from passing Core Web Vitals, and lower your cost per click through a better Quality Score.

Our Process
We run a comprehensive performance audit, PageSpeed, Core Web Vitals, app profiling, media analysis, Velo code review, and real-device testing. You receive a ranked list of issues sorted by speed impact.
Every installed app, third-party embed, and custom script is profiled individually for JavaScript weight, API overhead, and render-blocking behavior. You see exactly what each element costs in load time.
Over 1–2 weeks, we implement all fixes: app cleanup, media optimization, Velo code refactoring, script deferral, animation tuning, and above-the-fold rendering improvements.
We monitor real-user field data (CrUX) over 2–4 weeks, making iterative adjustments until LCP, INP, and CLS consistently pass in Google's 28-day rolling window, lab scores.
You receive complete documentation of every change made, a speed maintenance guide for future edits, and a before/after performance report with revenue impact projections.
