Core Web Vitals: LCP, INP, and CLS

We identify real bottlenecks — server, JavaScript, CSS, images, fonts, third-party scripts, or DOM structure — and optimize them without breaking functionality.

01 / SCOPE

What is included

For websites with a slow first load, a heavy mobile experience, low PageSpeed scores, or LCP, INP, and CLS issues.

  • + Lighthouse audit and browser performance profiling
  • + LCP resource optimization
  • + Reducing render-blocking CSS and JavaScript
  • + Responsive WebP/AVIF and proper lazy loading
  • + Cache headers and server-side bottlenecks
  • + DOM and third-party script optimization
  • + CLS and interface responsiveness control
02 / PROCESS

How we build a project

01

Measure

We establish the baseline and identify real problems.

02

Profile

We identify resources and code that block rendering.

03

Optimize

We fix the highest-impact bottlenecks.

04

Regression

We verify that the functionality still works correctly.

05

Verify

We remeasure desktop and mobile performance.

03 / TECHNOLOGY

Technology selected for the task, not the other way around.

Lighthouse, Chrome Performance, WebP/AVIF, caching, critical rendering path, CDN, Nginx, WordPress/WooCommerce optimization. We choose the stack after understanding the functional, SEO, and performance requirements of the specific project.

04 / FAQ

Frequently asked questions

Is a PageSpeed score of 100 possible?

Sometimes, but the goal is not a decorative number — it is fast real-world interaction without breaking business functionality.

Is a caching plugin enough on its own?

Not always. If the bottleneck is in database queries, JavaScript, or a heavy page structure, caching alone does not remove the root cause.

Can WooCommerce be optimized?

Yes. For WooCommerce, we separately analyze queries, transients, catalog rendering, plugins, images, and checkout.
