Website Development

Fast Websites Built for SEO

A website is more than good looks. It has to be fast, readable by Google, and ready to grow. We build to a clear technical standard, not to a number we can't control.

kenapa website saya lambat

Why a site can be slow, or pretty but failing

Before we talk design, we read what is holding your site back. These are the patterns we most often find.

The site is heavy from stacked themes and plugins

Every plugin ships its own CSS and JavaScript, and most of it you never use. We build lean: only the code a page truly needs reaches the browser.

Large, unoptimized images stall the load

A 4 MB photo shrunk by CSS still downloads in full. We serve responsive sizes, modern formats (WebP/AVIF), and lazy-loading, so what is off-screen never slows what is visible.

Fine on desktop, slow and broken on mobile

Most of your visitors are on phones with patchy networks, and Google judges the mobile version first. We test on real devices and networks, not just a developer wide screen.

Striking to look at, unreadable to search engines

A beautiful site can still fail if its content is rendered late by JavaScript, with no semantic HTML, meta, or structured data. We render on the server and mark the content up correctly from the start.

apa itu core web vitals

The Core Web Vitals standard we build to

Four metrics Google uses to judge page experience. Each has a clear target and concrete work behind it.

LCP: main content appears fast

We server-render, preload critical assets, and serve the hero image via CDN so the largest element paints first.

LCP <2.5s

INP: the site responds when touched

We ship minimal JavaScript and break up heavy tasks, so buttons and menus react without a felt delay.

INP <200ms

CLS: the layout does not jump

We reserve dimensions for images, ads, and embeds up front, and set fonts so text does not shove content as it loads.

CLS <0.1

TTFB: the server answers without waiting

We use cached rendering (SSR/ISR), fast hosting, and edge delivery so the first byte arrives quickly.

TTFB <0.8s

The SEO-ready build checklist

Not an afterthought. This is what is already in place on every site before we hand it over.

  • Server rendering (SSR/ISR) so content is readable at once
  • Clean, consistent URL structure
  • A correct XML sitemap and robots.txt
  • Canonical tags to prevent duplicate content
  • Core Web Vitals passing the "good" thresholds
  • Responsive images in modern formats, lazy-loaded
  • Assets minified and loaded only when needed
  • One H1 per page with a logical heading hierarchy
  • Semantic HTML and alt text on every image
  • A title and meta description on each page
  • Internal links connecting related pages
  • JSON-LD structured data (schema) for key content
  • Open Graph and Twitter cards for clean sharing previews
  • hreflang and lang tags if the site is bilingual

Tell Us About Your Website Needs

Answer a few quick questions and we'll give you our best recommendation.

What do you need? 🚀

pertanyaan soal pembuatan website

Honest questions about website development

does a fast website automatically rank on google

Not automatically. Speed and page experience are one ranking factor, not the only one. A fast site gives the right foundation, but ranking still needs relevant content and authority. We build that foundation as solid as it gets.

how long does building a website take

A company-profile site usually takes 4-8 weeks, depending on page count, content readiness, and custom needs. We give a realistic timeline up front and flag what can slow it down, like assets that are not ready. We do not promise "done in a week".

is it better to use wordpress or custom next.js

It depends on your needs. If a non-technical team changes content often, WordPress is practical. If performance and SEO are the priority and you want a lean, durable site, custom Next.js wins. The comparison above helps you choose, and we will tell you honestly which fits.

can i update content myself after the site is built

Yes. We set up a CMS or editor to match the chosen technology, then give a short walkthrough so your team can change text and images without touching code. For larger structural changes, we are still here to help.

can my old website be optimized or must i rebuild

We audit first before recommending. Often speed and SEO issues can be fixed without a rebuild. But if the foundation is too weighed down by old themes and plugins, rebuilding is actually cheaper long term. We tell you which makes more sense for your case.

does the price include hosting and domain

Domain and hosting are recurring costs separate from the build fee, and we help you pick and set them up. What each package includes is made clear before we start, so there are no surprise costs midway.
