Core Web Vitals Services

Core Web Vitals (LCP, INP, CLS) are Google’s official ranking signals that measure the usability of a web page. Passing these scores in field data directly impacts your organic Google rankings, decreasing mobile bounce rates and maximizing conversions across viewports.

These endpoints use session tokens for inventory and security validation. Aggressive optimizations would risk breaking the checkout flow or failing payment validation. Keeping these out of optimization scope maintains 100% transactional integrity and PCI compliance while still optimizing 95%+ of your traffic-driving pages.

We have a strict 90+ Google PageSpeed Score Guarantee (desktop/mobile) with a 100% money-back refund policy. We will run baseline performance audits before starting work and if our engineers cannot achieve a 90+ performance score on your supported page templates, we will provide a full refund.

We fix unexpected layout shifts by making sure all of your images have defined width/height attributes, reserving space for your marketing widgets and ads, and avoiding render-blocking CSS or JavaScript that cause webfont or content shifts.

We optimize for both. Lab Data (Lighthouse / PageSpeed Insights) gives us a diagnostic baseline where we hit our 90+ performance score guarantee. Meanwhile your Field Data (Chrome UX Report / Real User Monitoring) will see a steady improvement in CLS, FID and LCP as we address the underlying technical causes.

Our optimizations apply to your entire platform infrastructure. Whether you have WordPress, Shopify, Magento, Webflow or a custom PHP/Laravel solution, we optimize your entire catalog of templates including your homepages, category grids, blog archives, landing pages and individual product pages domain-wide.

Our optimizations focus on improving Largest Contentful Paint (LCP) by optimizing your critical rendering path. We can help defer non-essential rendering resources like fetchpriority=”high” banners and hero content, leveraging next-gen image formats and edge caching to shrink TTFB below 200ms.

We resolve high INP scores by resolving long-running JavaScript tasks which interrupt user initiated interactions. This includes splitting up long JS tasks, deferring non-essential 3rd party resources like social pixels and chat widgets, and optimizing your event-listener budget.

None of our optimization work will touch your production environment. All optimizations are implemented using clean methods on staging clones or draft themes so your existing responsive layout, analytics tracking and interactive elements will remain untouched.

Most of optimizations can be implemented and deployed within 2-4 working days. We typically need Administrator access to your CMS dashboard (WordPress, Shopify, Webflow, etc) and hosting control panel (cPanel/SSH/Cloudflare) if server-level optimizations are needed.
