What we do

WordPress speed optimization services cover everything that makes your site load fast for real visitors. We improve your page speed by tuning caching, a CDN, images, code, the database, hosting and your Core Web Vitals.

At DevDiggers, the same developers who build our 26 plugins do the tuning. We fix what is actually slow instead of stacking another cache plugin on top of the problem.

Why speed matters

Why WordPress speed optimization is worth it

A slow site quietly costs you rankings, visitors and sales every day. Here is what faster pages give you back.

Faster sites rank higher

Core Web Vitals are a Google ranking signal. A site that passes them on mobile has a real edge in search over a slow competitor.

Speed lifts conversions

Every extra second of load time costs you sales and signups. Faster pages keep visitors moving toward checkout instead of leaving.

Slow pages lose visitors

Most people leave a page that takes over three seconds to load. Cut that wait and more visitors stay long enough to act.

Most traffic is mobile

Your customers shop on phones and slower networks. We tune for mobile first, where speed is hardest to get right and matters most.

What we optimize

What our WordPress speed optimization services cover

We work through every layer that slows a WordPress site down. Need broader help too? See our WordPress development services.

Caching

Page caching and a global CDN

The biggest single win for most sites. We set up page cache, object cache and a CDN. Repeat visits and far-away visitors load a ready-made page from a nearby server instead of building it fresh from the database.

  • Page and object cache tuned for your site
  • CDN so far-away visitors load from a nearby server
  • Redis or Memcached where it helps
  • Lower TTFB on every request
Images

Image optimization and lazy loading

Images are usually the heaviest part of a slow page. We convert them to WebP or AVIF, serve the right size for each screen, and lazy-load anything below the fold to protect your LCP.

  • WebP and AVIF conversion
  • Correct sizes with srcset
  • Lazy loading below the fold
  • A real, preloaded LCP image
Code

CSS and JavaScript optimization

We minify your CSS and JavaScript, remove render-blocking files, and defer or delay the scripts that hold up the first paint. That is what drops INP and gets your page interactive sooner.

  • Minify and combine where it helps
  • Remove render-blocking CSS and JS
  • Defer and delay heavy scripts
  • Strip unused CSS and JavaScript
Database

Database cleanup and tuning

Old revisions, expired transients and orphaned rows make every query slower. We clean the database, add indexes where they help, and keep autoloaded data small so admin and checkout stay fast.

  • Clear revisions, transients and spam
  • Trim bloated autoloaded options
  • Add indexes for slow queries
  • Schedule cleanup so it stays lean
Core Web Vitals

Core Web Vitals tuning

We tune the exact metrics Google measures. That means LCP under 2.5 seconds, INP under 200 milliseconds and CLS under 0.1. We check against your real field data, not just a one-off lab test.

  • LCP, INP and CLS all in the green
  • Fixed against real field data
  • Checked in PageSpeed Insights and GTmetrix
  • Layout shift removed for a stable page
Hosting

Hosting and server tuning

Sometimes the fastest win is the server. We set the right PHP version, turn on OPcache and tune server-level cache. If your host is the real limit, we tell you honestly and help you move.

  • Latest PHP with OPcache on
  • Server-level and full-page cache
  • TTFB brought under control
  • Honest hosting advice, no sales pitch
Core Web Vitals

The three metrics we tune your site to pass

Google scores every page on three Core Web Vitals. Here is what each one means and the target your site needs to hit.

Largest Contentful Paint

When your main content appears. We fix it with a real hero image, caching and a faster server response.

Target: under 2.5s

Interaction to Next Paint

How fast the page reacts to a tap or click. We cut heavy JavaScript so it responds right away.

Target: under 200ms

Cumulative Layout Shift

Content jumping as the page loads. We reserve space for images, ads and fonts so nothing moves.

Target: under 0.1
Common causes

What slows a WordPress site down

Most slow sites share the same handful of causes. Our audit finds which of these are hurting yours, then we fix them in order of impact.

Unoptimized imagesFull-size JPGs and PNGs that were never compressed or converted to WebP.
No caching set upEvery visit rebuilds the page from the database instead of serving a cached copy.
Render-blocking codeCSS and JavaScript that load before the page can paint anything on screen.
Too many pluginsPlugins that each add scripts and queries, or overlap doing the same job.
Slow hosting and high TTFBA cheap or overloaded server that takes too long to send the first byte.
No CDNDistant visitors pull every file from one origin server, adding round-trip delay.
A bloated databaseOld revisions, expired transients and autoloaded data that slow every query.
A heavy page builderDrag-and-drop builders that add layers of markup and scripts to every page.
Before and after

What a typical speed optimization changes

Real numbers vary by site and starting point. These are the ranges we usually move a slow WordPress site through.

Metric Before After
PageSpeed score (desktop) 40 to 70 95 to 100
PageSpeed score (mobile) 20 to 50 80 to 100
Largest Contentful Paint 4 to 8s Under 2.5s
Interaction to Next Paint 300 ms plus Under 200 ms
Cumulative Layout Shift 0.25 plus Under 0.1
Time to First Byte 800 ms plus Under 300 ms
Core Web Vitals Failing Passing

Mobile scores are graded on a throttled connection and a slower device, so they read lower than desktop by design. We tune for both, and a 100 on desktop with strong mobile numbers is a realistic target for most sites.

Who it's for

Who we speed up

Slow pages cost every kind of site. These are the ones we speed up most.

Online stores

Every second of delay costs a WooCommerce store sales at the checkout.

High-traffic and enterprise

Large sites where slow pages hit rankings and server costs at scale.

Publishers and blogs

Content sites where speed protects search rankings and ad revenue.

Marketplaces

Multi-vendor stores with heavy pages that need to stay fast under load.

Agencies and freelancers

Send us a slow client site and we get it passing Core Web Vitals, with no delays.

Growing startups

Teams that need a quick, measurable speed win before a launch or campaign.

What it costs

What WordPress speed optimization costs

Most services hide pricing until a call. Here are honest ranges so you can budget first. Your final quote depends on your site, and we agree it in writing before any work starts.

Speed audit

A full report on what is slowing your site and the exact fixes it needs. Credited toward the work if you go ahead.

$100 to $300

One-time optimization

A full speed pass on your live site. The price tracks your platform, page count and how far behind the site starts.

$500 to $1,500

Store or large site

A WooCommerce store or a big site with many templates, third-party scripts and heavy plugins that need sorting out.

$1,000 to $5,000+

Care and speed plan

We keep your site fast as it grows, with monitoring, updates and priority fixes when a metric starts to slip.

$150 to $500/mo

These are rough estimates, not a menu. A small blog costs less than a store with heavy plugins and a checkout to protect. Send us your URL and we quote the real number.

How we work

A clear path from slow to fast

The same six stages on every project, so you always know what happens next.

  1. 01

    Audit

    We measure your site with real field data and lab tools, then find exactly what is slowing each page down.

  2. 02

    Plan

    You get a clear list of fixes, ranked by impact, with the result each one should bring and a fixed price.

  3. 03

    Optimize

    We apply the fixes on a staging copy first, so your live site never breaks while we work on it.

  4. 04

    Test

    We re-test on desktop and mobile and confirm your Core Web Vitals pass, not just a single lab score.

  5. 05

    Report

    You see before-and-after numbers in plain language, so you know exactly what changed and why it matters.

  6. 06

    Monitor

    On a care plan we keep watching your speed and step in before new plugins or content slow it back down.

Why DevDiggers

We build and run fast sites

We ship 26 plugins and run our own store on WordPress. We tune speed on real sites every week, not as a side service.

We fix the cause, not the score

Your design stays the same

Speed work happens in the background. Your site looks and works exactly as it did, only it loads faster.

Talk to the developer

You work with the person doing the tuning, not an account manager in the middle.

Support that replies in hours

FAQ

WordPress speed optimization, answered

The questions site owners ask us before a speed project starts.

Get a Speed Audit

WordPress speed optimization is the work of making your site load faster. It covers caching, a CDN, images, code, the database, hosting and the Core Web Vitals that Google measures.

An audit runs $100 to $300 and a one-time optimization $300 to $1,500. A large store costs more. We send a fixed quote for your site before any work starts.

Most sites are done in three to seven days after the audit. A large store with many plugins and templates takes longer. We give you a clear timeline with your quote.

No. The work happens in the background. Your design, layout and content stay exactly the same. Your site just loads faster for every visitor.

Yes. We tune LCP, INP and CLS so your field data passes, not only a one-off lab test. Passing these helps both your ranking and your visitors.

It can be either. A one-time pass fixes your site today. A care plan keeps it fast as you add plugins and content, with monitoring and priority fixes.

Yes. We ship 26 WooCommerce plugins and tune store speed often. Stores have heavier carts, accounts and queries, and we know where they slow down.

We will tell you honestly. If hosting is the real limit, we say so and help you move. We do not hide a hosting problem behind more plugins.
