FIND THE BOTTLENECK FIRST

Why is your WordPress site slow?

A slow website rarely has one universal fix. I check the pages and customer journeys that matter, then separate changes I can make from hosting or third-party limitations.

01

Heavy images & media

Oversized banners, product images and videos can delay the content visitors came to see.

02

Hosting & server delays

A slow server response or restricted hosting can hold back every page before it renders.

03

Plugins & third-party scripts

Overlapping plugins, trackers, embeds and external APIs can add requests and busy work.

04

Rendering, fonts & caching

Blocking assets, late fonts and unsuitable cache rules can make a page feel slow or unstable.

WORDPRESS PERFORMANCE OPTIMIZATION

The right fixes.
For the website you already have.

Keep the useful parts of your site. Improve how they load, respond and stay stable—with changes matched to the selected scope.

LCP · Loading

Priority content & images

Investigate the main image and critical rendering path, appropriate preloading, responsive sizes and server response. Use WebP or AVIF where suitable; avoid lazy-loading the true hero image.

INP · Responsiveness

Scripts that work with your visitors

Review expensive JavaScript, long tasks and interaction delays. Adjust script/style loading where safe, with menus, forms and essential integrations tested afterwards.

CLS · Stability

Layouts that keep their place

Set useful media dimensions and investigate late-loading fonts, embeds or content that moves the page. Aim for a steadier experience instead of chasing a decorative score.

Delivery & assets

Caching, CSS, fonts & CDN

Configure suitable page/browser caching, review blocking CSS and font delivery, and tune an existing supported CDN. Personalised and transactional pages need exclusions.

Data & mobile

A leaner, more usable site

Review routine database cleanup after backup within Growth/Advanced scope, investigate autoload concerns and test the agreed pages on mobile. Large rewrites need a separate quote.

Commerce-aware

Cart and checkout safeguards

In Advanced, review eligible WooCommerce journeys and dynamic cache rules. Preserve cart, account and payment behaviour. Deep store development remains a separate service.

A CAREFUL, REVIEWABLE PROCESS

See how the optimisation process works.

You know what is being tested, what changed and what remains outside the agreed scope.

  1. Baseline & scope

    Agree representative pages and key journeys. Record mobile/desktop measurements and relevant test conditions.

  2. Backup & preparation

    Review backups, recovery options and staging where available. Confirm appropriate access before changes.

  3. Targeted technical fixes

    Apply the suitable image, cache, code and delivery improvements in your package. Discuss dependencies first.

  4. Mobile & desktop QA

    Retest layouts, menus and forms; check cart/checkout where included. Adjust or skip incompatible changes.

  5. Report & handover

    Compare like-for-like tests, explain caveats and share the changes made, next steps and support limits.

Careful work, realistic expectations.

Backups and testing reduce risk; they do not guarantee zero data loss or permanent performance. Hosting, new content, plugins and third-party changes can affect later results.

EVIDENCE WITH CONTEXT

Real speed results.
Clear about what they prove.

Your delivery report compares the agreed pages under comparable test conditions, with a clear record of the changes made and any limits that remain.

What your report should show

  • Tested URL, date, device and test method.
  • Before/after mobile and desktop lab measurements.
  • Changes made and functional journeys checked.
  • Hosting, script and integration limitations.
  • Available real-user data, labelled separately.

Report outline. The actual measurements are recorded for your agreed pages during the project.

HOW WE MEASURE PERFORMANCE

Lab tests ≠ real-user field data.

Lighthouse helps diagnose a controlled page load. PageSpeed Insights may also show CrUX data from the previous 28 days when enough real-user samples are available. A single lab score does not prove a Core Web Vitals pass.

Google’s good-experience targets at the 75th percentile are LCP ≤ 2.5 seconds, INP ≤ 200 milliseconds and CLS ≤ 0.1. These are engineering targets, not package guarantees.

BEFORE YOU CHOOSE

WordPress speed optimization FAQs

Clear answers about scope, safety, timing and what you receive.

Ask about your website ↗
How much does WordPress speed optimization cost?

Speed Starter is $79 USD, Growth is $179 USD and Advanced is $349 USD, billed once per eligible single WordPress website. The page limits are totals, not additional pages on top of another plan. Hosting, premium plugins, CDN subscriptions, domain fees and other third-party costs are separate unless agreed. If your requirements do not fit, request a custom quote before buying.

Can you guarantee 90+ on mobile and desktop?

No blanket PageSpeed score or fixed loading-time guarantee is offered. Theme code, hosting, content, traffic, third-party scripts and external APIs affect the outcome. I record a baseline, make the agreed changes, retest comparable pages and explain improvements and remaining limitations.

Will my website, forms, WooCommerce cart or checkout break?

I review backup or staging options before changes and test the important journeys within the agreed scope. Cart, checkout, account and other personalised pages need appropriate cache exclusions. If an optimisation is incompatible, I adjust or skip it rather than knowingly breaking a working feature. No change process can promise zero risk or zero data loss.

How long does WordPress speed optimization take?

The estimates are 2 business days for Starter, 3 for Growth and 5 for Advanced after secure access and scope confirmation. They are estimates, not automatic delivery guarantees. Missing access, hosting restrictions, complex code or third-party issues can affect timing; changes are discussed before additional work.

Do I need WP Rocket, Cloudflare or another paid plugin?

Not necessarily. I first review the suitable tools and licences already available. Any recommended paid plugin, hosting change, CDN or subscription needs your approval and is not included by default. A plugin purchase alone does not establish that the website is properly optimised.

Do you work with Elementor and WooCommerce websites?

Yes, where technically feasible within the agreed scope. Elementor layouts and WooCommerce journeys need testing when script loading or caching changes. The Advanced plan includes a conditional cart and checkout performance review; large stores, multisite and heavy custom applications may need a separate quote.

What do I receive after the work?

A before/after mobile and desktop comparison for the agreed pages, a list of changes, the test method and relevant limitations. The report distinguishes lab tests from available real-user data and records functional checks. You also receive practical handover notes and the plan’s stated period of fixes related to delivered work.

What counts as a scoped revision or post-delivery fix?

A scoped revision adjusts delivered optimisation work within the original agreed requirements; it does not add new templates, features or a redesign. Starter includes 1 revision and 7 days of related fixes, Growth 2 and 14 days, and Advanced 3 and 30 days. Requests and timing are agreed at handover. Ongoing monitoring and new work are separate.

Can I get a custom quote for a large or complex website?

Yes. Share the public URL, platform details and the journey that feels slow. Multisite, large stores, custom applications, major code rewrites and hosting migrations are assessed separately. No payment is needed to request a review. Do not send passwords, customer records or payment details through the public form.

What happens after I purchase a package?

WooCommerce records the order and the configured gateway verifies payment. After payment confirmation, Nithu reviews the website and contacts you using the order details to agree scope, secure access and delivery timing. A purchase does not authorise extra charges. If the site is unsuitable for the selected fixed scope, discuss an agreed resolution before work; the linked terms and refund policy apply.

A SENSIBLE NEXT STEP

Ready to fix a slow WordPress site?

Share your public URL and what feels slow. I’ll review your enquiry, clarify the scope and discuss the right next step.

  1. Tell me the website and the affected journey.
  2. Receive a personal response about fit and dependencies.
  3. Agree scope, access and timing before work.

No payment is required to request a speed review. A review enquiry is not a full technical audit or a promise of a particular score.
