Website Speed Optimization and Core Web Vitals

A slow site loses customers and search rankings. We optimize page load so pages open instantly: fewer bounces, higher conversion, cheaper paid traffic, and better rankings. First an audit, then a quote for specific fixes - with before and after measurements.

What we optimize

Speed is made up of many details. We audit to find the bottlenecks and optimize what delivers the most impact:

  • LCP. We speed up main content rendering - critical resource prioritization, load order, server response.
  • CLS. We eliminate layout shifts - reserving space for images, banners, and fonts.
  • INP. We improve responsiveness - lightening and breaking up heavy JavaScript.
  • Images. Compression, WebP/AVIF, responsive sizes, lazy loading.
  • Fonts. Non-blocking loading without text flicker.
  • JS and caching. Removing unnecessary code, bundle splitting, caching, and CDN.

Why speed matters

EffectWhat it means
SEOCore Web Vitals are a Google ranking factor, especially on mobile
ConversionEvery extra second of load time raises the bounce rate
Paid trafficA fast landing page improves Quality Score and lowers cost per click
Crawl coverageFast sites are crawled more thoroughly and completely by search bots

How we work

We start with a speed audit: measuring Core Web Vitals on real pages, finding bottlenecks, and prioritizing fixes. Then we fix a quote for the optimization - you pay for specific fixes with measurable results, not for abstract "speeding up". After the work we show before and after measurements.

When speed optimization is not enough

Sometimes a site is slow not because of individual mistakes but because of the platform itself - a heavy CMS or page builder pulling in code that cannot be optimized away. In that case the honest answer is not to optimize the hopeless, but to do a migration to a modern platform. If the site is fundamentally healthy, speed optimization pairs well with maintenance - keeping speed in good shape continuously.

FAQ

What are Core Web Vitals?

Core Web Vitals are a set of Google metrics that measure real user experience: LCP (how fast the main content renders), CLS (visual stability - absence of layout shifts), and INP (responsiveness to user actions). Google uses these metrics as a ranking factor, and users experience them as a reason to stay or leave.

Why is my site slow?

The most common causes are uncompressed images in the wrong format, render-blocking JavaScript, slow fonts, missing caching, and a heavy CMS or page builder pulling in unnecessary code. An audit shows exactly what is slowing your site down and which fixes will have the greatest impact.

How much will you speed up my site?

It depends on the starting point. On neglected sites LCP can often be improved several times over and PageSpeed scores can move from the red zone into the green. We give an accurate estimate after the audit - promising specific numbers without seeing the site would not be honest.

Does speed affect SEO?

Yes. Core Web Vitals are an official Google ranking factor, especially on mobile. Beyond the direct ranking impact, a fast site is crawled more thoroughly and retains users better: lower bounce rate, higher conversion, and cheaper paid traffic due to a better Quality Score.

How much does speed optimization cost?

Cost depends on the scope of work, which becomes clear after the audit. We first run a speed audit and identify bottlenecks, then fix a quote for the optimization. That way you pay for specific fixes, not for abstract "speeding up".
