Website speed optimization and Core Web Vitals fixes

Slow pages lose people before they even see your offer. We find what's dragging your site down, fix it, and keep it fast, on WordPress, Shopify, Next.js or custom builds.

  • Pages that load before people give up
  • Better Core Web Vitals for search
  • Checks so it doesn't quietly slow down again

What we fix

  • Speed audit

    We measure what's slow and why, page by page, on real phones and connections.

  • Image optimization

    Right-sized images in modern formats, loaded only when they're needed.

  • Caching & CDN

    Your pages served quickly from close to your visitors.

  • Code cleanup

    Heavy scripts, unused plugins and render-blocking code removed or deferred.

  • Hosting upgrades

    If the server is the bottleneck, we move you somewhere faster.

  • Monitoring

    We keep an eye on speed so it doesn't slip back.

Website speed optimization that starts with measuring

Guessing at speed fixes wastes money. We start by measuring your key pages, such as the homepage, top landing pages, product pages and checkout, on the devices your customers actually use. Then we rank the problems by how much time each one costs your visitors.

The usual suspects are oversized images, too many plugins or apps, third-party scripts like chat widgets and trackers, slow hosting and fonts that block the page. Most sites get much faster from targeted fixes, without a rebuild.

Fix Core Web Vitals: LCP, INP and CLS

Core Web Vitals are Google's measures of how a page feels to use. Largest Contentful Paint (LCP) is how quickly the main content shows up. Interaction to Next Paint (INP) is how quickly the page responds to a tap or click. Cumulative Layout Shift (CLS) is how much the page jumps around while it loads.

We fix each one at the source: preloading and compressing the hero image for LCP, breaking up long-running scripts for INP, and reserving space for images, ads and embeds for CLS. Then we check the real-user numbers, not just a one-off lab test.

Faster sites on WordPress, Shopify and custom builds

On WordPress we trim plugins, fix the theme, add proper caching and tune the database. On Shopify we cut app bloat and heavy theme code. On Next.js and custom sites we look at rendering, bundles and data fetching. If the honest answer is that a rebuild or a hosting move will do more, we'll say so and explain the trade-off.

  • Before-and-after numbers for every fix
  • No rebuild unless it's truly the better option
  • Ongoing checks with managed hosting

Performance questions

Will a faster site help my SEO?

Page experience, including Core Web Vitals, is one of the signals Google uses, and faster pages keep visitors around longer. Speed is one piece of SEO, not all of it.

Do I need a new website to make it faster?

Usually not. Most sites get much faster with targeted fixes. If a rebuild is the honest answer, we'll tell you why.

What are Core Web Vitals?

Three measures Google uses for how a page feels: how fast the main content loads (LCP), how quickly it responds to taps and clicks (INP), and how much it shifts while loading (CLS).

Can you speed up a WordPress or Shopify site?

Yes. We work on WordPress, WooCommerce, Shopify, Next.js and custom sites.

How do I know if my website is too slow?

If pages take more than a few seconds to show their main content on a phone, or the page jumps around while it loads, visitors notice. Google's PageSpeed Insights gives a quick read, and our speed audit shows exactly which pages and which causes matter most.
