Website speed optimization

Your website opens faster, especially on phones and mobile data. I measure speed with Core Web Vitals before and after the work, so you can see exactly what changed.

Discuss your project

Who it is for

  • On a phone the site takes several seconds to open, and visitors leave before it loads.
  • PageSpeed Insights and Search Console show red scores and Core Web Vitals issues.
  • You pay for ads, but some visitors leave while the page is still loading.
  • Over time the site has piled up plugins, trackers and widgets and become slow.

What is included

  • Baseline measurements: Core Web Vitals (LCP, INP, CLS) for the key pages on phones and desktops
  • Image compression, modern formats and lazy loading as the visitor scrolls
  • A review of scripts, plugins and widgets: what to remove, defer or replace
  • Caching and file compression set up within the site and CMS
  • Font optimization and a better loading order for styles
  • Follow-up measurements and a short report on what was done and which metrics changed

Billed separately

  • Rewriting a heavy theme or layout
  • Replacing a site builder with a custom build
  • Ongoing speed monitoring after handover

Price and timing

Estimated timing

1–2 weeks

What affects the price

  • What the site is built on: WordPress, a site builder or custom code
  • The number of key pages to measure and fix
  • How many plugins, scripts and third-party widgets the site has
  • Which caching settings your hosting allows

How we work

  1. Measurements: the speed of the key pages and a list of what slows them down

  2. A work plan: what gives a noticeable effect and what would require rebuilding the site

  3. Optimization on a copy of the site or step by step, checking that nothing breaks

  4. Follow-up measurements and a report with before and after metrics

Terms of work: payment, revisions, warranty

Example

A demo on fictional data and a real project from my portfolio with a similar task.

  • Demo

    Website before and after

    I show the difference using a fictional coffee shop: a deliberately outdated website and its reworked version that you can compare on one screen.

FAQ

How much does speed optimization cost?

From 600 BYN: measurements, image, script and cache optimization, and follow-up measurements. If the slowness comes from an outdated theme or a site builder, I will tell you after the measurements and suggest options.

Do you guarantee green PageSpeed scores?

No. The score depends on the platform, the hosting and third-party services on the site: chats, widgets, ad trackers. I remove the causes that can be fixed without rebuilding the site and show the result as before and after metrics, explaining what else is holding it back.

What are Core Web Vitals?

They are Google's metrics: how quickly the main content of a page appears (LCP), how quickly it responds to actions (INP) and whether the layout shifts while loading (CLS). Google takes them into account in rankings, and visitors notice them immediately.

Could the optimization break the site?

I test each change first on a copy of the site or on one page, then on the whole site. If something does not work as expected, I roll the change back before it reaches the whole site.

Do you have an example of a fast website?

The site you are reading: Next.js with static generation, so pages are built in advance and served to the browser ready-made. For WordPress sites I use other techniques: caching, image optimization and a review of plugins.
