WordPress,
until Core Web Vitals go green.

We pinpoint why your site feels heavy and slow through measurement, then improve load speed, Core Web Vitals, and bounce rate step by step in a measure → improve → verify cycle. We reach beyond what image compression or a caching plugin alone can address. Depending on your site’s structure and current bottlenecks, we also propose improvements that don’t require a server migration. Start with a 30-minute free consultation to get a read on where your bottlenecks are.

Pain points

Do any of these sound familiar?

Speed problems come from a mix of factors — site structure, server, content, and operations. A single fix often isn’t enough to solve them.

Your PageSpeed Insights score stays red or yellow, and improvement has stalled.
Your Core Web Vitals (LCP / INP / CLS) aren’t passing, and Search Console is flagging warnings.
You can tell load speed drops every time you add a plugin.
Mobile access is slow and bounce rate is high.
The admin and editing screens feel sluggish.
You hired a vendor promising “faster performance,” but couldn’t feel the difference.
Reasons

A “measure → improve → verify” cycle

Speed work starts with diagnosis, not blind patching. We nail down what’s causing the slowness in numbers before touching anything.

01

Measure

Using Lighthouse / WebPageTest / Chrome User Experience Report, we measure TTFB / FCP / LCP / INP / CLS / TBT, and separate server-side from front-end bottlenecks.

02

Improve

Based on the measurements, we implement fixes in order of impact — plugin cleanup, cache tuning, image / JS / CSS optimization, CDN adoption, DB tuning, and only where it’s needed.

03

Verify

We put the before-and-after numbers side by side and share the Core Web Vitals pass/fail, PageSpeed score, and real-device rendering time. We keep observing with a monthly report.

Scope

What we cover

We do only the parts your site needs, depending on its state. We don’t bundle in low-impact measures across the board.

01 Diagnose

Speed diagnosis report

We measure your current site with Lighthouse / WebPageTest and document the bottlenecks, improvement priorities, and expected impact. You can also choose to stop at the diagnosis.

  • Lighthouse / PageSpeed measurement
  • Staged analysis via WebPageTest
  • Real field data from Chrome UX Report
  • Core Web Vitals pass/fail assessment
  • Improvement priority map (impact × difficulty)
  • Report delivered as PDF
02 Image

Image & media optimization

We restructure the images accumulated in WordPress with WebP / AVIF conversion, appropriate size generation, and lazy loading — all without changing how your CMS editors work.

  • Bulk WebP / AVIF conversion of existing images
  • Responsive size generation
  • Lazy loading (loading="lazy")
  • Optimization of background and decorative images
  • Lightweight video embedding
  • Designed to leave editor workflows unchanged
03 JS / CSS

JavaScript / CSS optimization

From the JS / CSS that themes and plugins emit, we keep only what’s truly needed and clear render-blocking resources, lowering front-end rendering cost.

  • Detecting and reducing unused JS / CSS
  • Extracting critical CSS
  • Deferring / async-loading JS
  • Cleaning up third-party tags
  • Font subsetting
  • Clearing render-blocking resources
04 Cache / CDN

Cache & CDN design

We combine server cache, browser cache, and a CDN (Cloudflare / CloudFront) to bring TTFB down a level, and design it to coexist with dynamic sites.

  • Cloudflare / CloudFront design
  • Server cache (Nginx / Redis)
  • Browser cache optimization
  • Coexistence with dynamic content
  • Cache invalidation strategy
  • Design for multilingual sites
05 Plugins

Plugin cleanup

Plugins readily affect load speed. We inventory the unused, heavy, and vulnerable ones and pare the setup down to the minimum you need.

  • Auditing how every plugin is actually used
  • Proposing alternatives to heavy plugins
  • Resolving overlapping functionality
  • Removing vulnerable plugins
  • Replacing features built with plugins
  • Establishing operating rules
06 DB

Database & admin speedup

We fix DB-side slowness — post and comment volume, wp_options bloat, and more — and clear the sluggishness of the admin screen at the same time.

  • Countering wp_options bloat
  • Cleaning up unnecessary revisions
  • Adding indexes and tuning queries
  • Resolving WP_Query N+1 issues
  • Optimizing autoload options
  • Improving the feel of the admin screen
Process

The path to improvement

You can choose to stop at the diagnosis. If the diagnosis finds your site is fine as is, we don’t proceed to implementation.

  • 01Free consultation — we hear the site URL and your sense of the current issues (30 minutes).
  • 02Speed diagnosis — we measure the current state with Lighthouse / WebPageTest / Chrome UX Report and report improvement priorities.
  • 03Proposal & quote — we present the improvement menu, expected impact, and timeline in writing.
  • 04Implementation — we do only the agreed scope, and verify on staging before going to production.
  • 05Verification & report — we put the before-and-after numbers side by side and report the Core Web Vitals pass/fail.

Comparison

Compared with the alternatives

There’s often room left to improve in areas that a caching plugin alone can’t reach.

Option A

Handling it in-house

  • You add a caching plugin and hit a wall
  • Progress stalls between your core work
  • Measurement tools are hard to read
  • Verifying the effect afterward is vague
Option B

Vendors promising “faster performance”

  • They just run through a set of stock fixes
  • No measurement, so you can’t confirm the effect
  • Many proposals assume a server migration up front
  • Thin evidence for how much they improve
SHANNON

Measure → improve → verify

  • We confirm the cause in numbers before acting
  • We also propose cases that need no server migration
  • We report before and after in numbers
  • Stopping at the diagnosis is fine
FAQ

Frequently asked questions

It depends on the site’s structure. For WordPress on shared hosting with a long TTFB and no caching set up, we can often cut LCP to less than half. For sites already tuned to some degree, the gains are more limited. We present the expected improvement range at diagnosis time.
In most cases, yes. Plugin cleanup, JS/CSS optimization, image optimization, and CDN adoption alone deliver large gains for the majority of sites. When a site is slow enough to require a server migration, we consider it together with a separate server diagnosis & migration.
At diagnosis time we check every plugin and the theme, and for any measure with compatibility concerns we present the approach in advance. Before going to production, we verify all features work in a staging environment.
It depends on the site’s structure and content. The Lighthouse score is just an indicator; what fundamentally matters is the real field data of Core Web Vitals (CrUX). We design for improving the user’s felt experience over the score itself.
WordPress is our main focus, but we can also handle other setups like PowerCMS, Movable Type, and Next.js + a headless CMS. Optimizations specific to a given system are tailored to the project.
Degradation after entering the operations phase does happen in practice. In the monthly ongoing plan, we observe the impact of added content and plugin updates and re-tune as needed.
