Website speed

PageSpeed 95+ websites in 3-5 days: how we build fast sites.

Websites built on React and Astro that Google PageSpeed scores at 95 or higher.

At SEO7.ES a website is built on React and Astro, not WordPress. That is why the page passes the Google PageSpeed test with ease: our websites score 95+. Every plan includes a PageSpeed 90+ guarantee, or we improve the site for free. A website on the Start plan is live in 3-5 days.

Quick answer

SEO7.ES websites score 95+ in Google PageSpeed. The speed comes from technology and build: React and Astro instead of WordPress, WebP and AVIF images with lazy loading, Brotli compression, critical CSS and font preloading. Every plan guarantees PageSpeed 90+ or we improve the site for free, and a €450 Start website is live in 3-5 days.

This article explains why our websites score 95+ in Google PageSpeed and what is behind it. We cover how Google calculates the speed score and which Core Web Vitals thresholds a page has to pass. We show the eight steps we use to bring a site to 90+ before handover and a table of speed techniques and the metrics they affect. At the end, answers to common questions: what a fast website costs, how to check speed yourself and what happens if the score is below 90.

How do we build websites with PageSpeed 95+?

Speed is built into the technology, not added after launch

Website speed is decided when the technology is chosen. We build on React and Astro: the browser gets ready-made HTML and JavaScript loads only where it is needed. Then comes the mandatory technical work in the plan: WebP and AVIF images with lazy loading, Brotli or Gzip compression, cache headers, critical CSS and font preloading. Before handover every site goes through a Lighthouse check and tuning to 90+, and in practice the result is 95+.

Building a fast website with a PageSpeed score of 95+
Website speed is decided during development, not after launch.
  1. 1Choose the stack: React and Astro instead of WordPress
  2. 2Build the pages into ready-made HTML at build time
  3. 3Convert images to WebP and AVIF, with srcset and lazy loading
  4. 4Extract critical CSS and preload fonts
  5. 5Add preconnect and dns-prefetch for external services
  6. 6Enable Brotli or Gzip compression and cache headers on the server
  7. 7Run Lighthouse and bring the score to 90+
  8. 8Test the site in all browsers and hand it over

What affects the Google PageSpeed score?

Charts on a laptop screen: checking website speed
Speed is checked by measuring: PageSpeed and Core Web Vitals.

Which techniques speed up a site and which metrics they affect

The PageSpeed score comes from the Lighthouse lab test. Google treats 90 to 100 as good, 50 to 89 as needing improvement and below 50 as poor. For real visitors Google uses Core Web Vitals over 28 days: the main block of the page (LCP) should render within 2.5 seconds, the response to an action (INP) should stay under 200 milliseconds and the layout shift (CLS) should not exceed 0.1. The table shows which technique in our plan affects which metric.

What speed guarantee do you get?

PageSpeed 90+ in the contract, 95+ in practice

Every website plan includes the guarantee: PageSpeed 90+ or we improve the site for free. In practice our websites score 95+. A website on the €450 Start plan (VAT included) is live in 3-5 days, a company website on the €790 Pro plan in 14-21 days and a store on the €1290 Max plan in 21-30 days. If we are late, you get 10% off the price, and edits are free for 30 days after launch.

Expert opinion
«Launch speed is decided by decisions made upfront, not by tooling. When structure, copy and blocks are settled before the first line of code, assembly is quick. Everything else is eaten by rework.»

Frequently asked questions.

What is Google PageSpeed?

A free Google service that scores page speed from 0 to 100, separately for mobile and desktop. It shows the Lighthouse lab test and real visitor data for the last 28 days. You can check your site at pagespeed.web.dev in a minute.

What PageSpeed score counts as good?

On the Google scale, 90 to 100 is good, 50 to 89 needs improvement and below 50 is poor. Our websites score 95+, and the contract guarantees at least 90.

How much does a fast website cost?

A website on the Start plan costs €450 with VAT: up to 12 pages, live in 3-5 days. A company website on Pro costs €790 and a store on Max €1290. The PageSpeed 90+ guarantee comes with all three plans. Payment in euros or crypto.

What happens if the score is below 90?

We improve the site for free until the score reaches 90. This condition is part of the guarantees in every website plan, so there is no separate charge for speed optimisation.

Why don’t you build websites on WordPress?

Most studios in Valencia build on WordPress, and the page drags its theme and plugins along. We build on React and Astro: the browser gets ready-made HTML, which keeps the PageSpeed score at 95+.

Can you speed up an existing website?

Yes. We start with a technical SEO audit (from €203) that shows what slows the page down. Fixes then go through website support (from €61), and if the old platform cannot reach 90+, it is better to rebuild the site on the Start plan.

Does speed affect Google rankings?

Yes, Core Web Vitals are part of the page experience signals Google uses in ranking. But speed does not replace useful content: a fast page that does not answer the customer’s question will not reach the top.

How can I check my website speed myself?

Open pagespeed.web.dev, paste the page address and choose the mobile tab. Look at the performance score and the three Core Web Vitals: LCP, INP and CLS. Check several pages, not just the home page.
