Core Web Vitals fix for WordPress

Failing Core Web Vitals? I find the cause and fix it.

Most slow websites were slow from day one. Bloated themes, unnecessary plugins, and poor development choices often create problems from the start.

I build lean, clean WordPress websites with performance and SEO in mind, so they load fast, deliver a better user experience, have a rank-ready structure, and stay easy to manage as your business grows.

  • LCP, CLS and INP fixed by cause, not by guess
  • Field data checked in Search Console, not only lab tests
  • Retest and report after the fix

The three metrics

Which metric is failing?

LCP too slow

Hero image, slider, fonts or slow server response.

CLS jumps

Images, ads, embeds or fonts shifting the layout.

INP laggy

Heavy JavaScript blocking taps and clicks.

Mobile only

Passes on desktop, fails on phones.

What I do

How I fix it

I start with real-user field data, then trace LCP, INP, and CLS issues to the exact elements, scripts, or interactions causing them.

Every fix targets the root cause, not just the score.

Common Questions

Frequently Asked Questions

Clear, honest answers about scope, safety, and performance expectations.

No. All work happens on a staging environment first. I create a full backup before starting. Changes go live during low-traffic hours after thorough testing.

On the Pro plan, if your site doesn’t achieve 100/100 on PageSpeed Insights (mobile and desktop) and pass all Core Web Vitals, you get a full refund. No questions asked.

Starter: 3-5 days. Pro: 5-7 days. Large WooCommerce stores may take 7-10 days. You’ll get a detailed timeline after the audit.

No. I take a full backup and work on staging first.

Not always, and I will not promise it. I aim for a fast real-user experience first.
