The design looks great, but nobody checked PageSpeed
The site is polished and it scores 47 on mobile. Full-resolution images, render-blocking scripts, no CDN. The test simply never got run before launch.
Core Web Vitals feed directly into how Google ranks you. A slow company profile also says something to a prospective client before they've read a line. Your site scores 95 or higher on PageSpeed Insights, and a failing Core Web Vital stops the build until it's fixed.
Built on the same performance stack most teams measure against.
Google factors Core Web Vitals into its rankings. A site that takes four seconds to load on mobile loses a measurable share of visitors before they even see the top of the page. For a company profile, every extra second of load time chips away at how credible you look.

LCP and CLS are both failing. The SEO team spotted the ranking drop. The developer calls it a complex fix, and four months later it's still sitting there.
Analytics, LinkedIn tracking, HubSpot, the cookie banner, and live chat together hold the main thread for around two seconds. Cutting any one of them turns into an internal debate.
Marketing uploads full-resolution images with each press release because no one set guidelines for image sizes. The site keeps getting heavier.
Each step produces something you can review. You sign off before we move to the next one, and every hand-off is written down so nothing gets lost between stages.
A full Lighthouse and WebPageTest audit runs on mobile and desktop, then on real devices under Indonesian network conditions. You get a list of fixes ordered by how much each one will help.
Company profiles go on Astro or Next.js with static generation, so every page is pre-rendered and served from the CDN edge rather than built fresh on each request. That keeps TTFB under 100ms.
Images converted to WebP or AVIF, responsive srcsets, lazy loading, and compression pushed as far as it goes without visible quality loss. We also subset fonts, sprite icons, and inline the critical CSS.
Render-blocking scripts get deferred or switched to async. Analytics loads after the first interaction, and chat widgets load only when someone wants them. We weigh each script against what it actually costs in speed.
We serve the site from the edge through Vercel or Cloudflare Pages. The CI pipeline blocks any deployment that would push the Lighthouse score below the number we agreed on.
Real files, working pages, and numbers you can check. Not a slide deck of promises.
A score of 95 or higher on PageSpeed Insights for mobile and desktop is the floor your site ships against, verified before handover.
With static generation and edge delivery, the first byte reaches the browser before most servers have even finished processing the request.
Core Web Vitals shape both your ranking and how the site feels to use. You get them measured on real devices over real network conditions.
Image guidelines, a sorted upload workflow, and a configured CMS keep the site from slowing down as your marketing team adds pages.
Usually, yes. The fixes that move the needle most, like image optimisation, deferring scripts, and CDN configuration, can often be done without rebuilding anything. We audit first, then tell you whether tidying up the current site or rebuilding it works out cheaper for you.
Google ranks pages using mobile PageSpeed no matter where your audience actually browses. So a weak mobile score still drags down your search rankings, including for the desktop visitors you care about.
We use WebPageTest with throttled profiles that mimic Indonesian 4G, and we measure on real mid-range Android handsets. That's a long way from lab numbers taken on a fibre connection inside a US data centre.
A Lighthouse score of 95+ is a clear, verifiable bar that maps to genuinely fast pages on real devices, not a vague target anyone can argue about. It also gives your team a number to defend against regressions over time. We ship against that floor and verify it before handover, so 'fast enough' is never left to opinion.
Core Web Vitals are three Google metrics: LCP (how fast the main content loads), INP (how quickly the page responds to interaction), and CLS (how much the layout shifts unexpectedly). Google factors them into rankings, and they closely track how fast the site feels to a real visitor. We measure all three on real devices and won't ship a failing vital.
The biggest factors are usually unoptimised images, render-blocking scripts, heavy third-party tags (analytics, chat, tracking), and how the server delivers pages. Fonts, the amount of JavaScript shipped, and whether content is cached at the edge also matter. We audit each of these and fix them in the order that gives you the most speed for the least effort.
Where your site is served from decides how quickly the first byte reaches the visitor. We serve from a CDN edge through Vercel or Cloudflare Pages, so pages come from a location near the user rather than a single distant server. Combined with static generation, this keeps Time to First Byte under 100ms even for visitors far from the origin.
Both. Lab tools like Lighthouse and WebPageTest give us a controlled, repeatable score during the build. We also look at field data (Core Web Vitals from real Chrome users) in Search Console once the site is live. Lab numbers catch issues early; field data confirms the experience your actual audience is getting.
Not if they're loaded carefully. We defer or async render-blocking scripts, load analytics after the first interaction, and load chat widgets only when someone opens them. Each script is weighed against what it actually costs in speed, so you keep the tools you need without paying for them on every page load.
That's the part most teams miss. We set image guidelines, configure the CMS to compress and resize uploads, and where it fits we add a CI check that blocks any deployment that would drop the Lighthouse score below the agreed number. So the site stays fast as your marketing team adds pages, not just on launch day.
Tell us where things stand right now. Within one working day we'll get back to you with a straight assessment of scope, timeline, and cost. There's no commitment to go further.
