prb.co.id website review

About 1.3 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 10.6 s faster on a phone.

79 files are served with short cache lifetimes, so returning visitors download them again (732 KiB).

43 images could be 1.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.0 s faster on a phone.

The HTML itself could arrive about 3.0 s sooner: redirects, a slow server response or missing compression delay everything after it.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 3.0 s).

The page goes through 3 redirects before it starts loading, costing about 2.4 s. Link and advertise the final URL directly.

Your mobile performance score is 53. Pages that score under 90 lose visitors before the first paint.

3 third-party services load with your homepage (Google CDN, Other Google APIs/SDKs and Google Fonts), adding 2.1 MB and 741 ms of main-thread time.

Google CDN costs a phone 626 ms of main-thread work and 1.8 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Reduce initial server response time. Google estimates savings of 609 ms on a phone.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 450 ms.

About 40 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Polyfills for old browsers add 31 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 3.0 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,773 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your server takes 709 ms to send the HTML. Google recommends under 600 ms; everything else waits for it.

22 KiB could be saved by minifying JavaScript.

12 long tasks block the main thread while loading, the longest for 161 ms. During a long task the page ignores taps.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Real visitors wait 6.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 6.4 s (75th percentile). Good is under 1.8 s.

Real visitors wait 5.5 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 30.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 21.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 33.5 s. Good is under 3.8 s.

The first text or image appears after 4.4 s on a phone. Good is under 1.8 s.

Your homepage downloads 5.8 MB in 192 requests on a phone: images 2.1 MB (152), scripts 2.0 MB (13) and other files 697 KiB (4). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.65 g of CO₂e: 198.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Links do not have a discernible name (10 elements).

4 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

Your page has no <title>, so Google has to invent the blue link in search results.

No meta description, so Google writes its own snippet from whatever text it finds.

There is no <h1>, so neither visitors nor Google get a clear main headline.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://prb.co.id/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at prb.co.id/robots.txt, the first file search crawlers ask for.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

9 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://prb.co.id/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

No viewport meta tag, so phones render the desktop layout zoomed out.

The page has no <!DOCTYPE html>, so browsers render it in quirks mode.

No character set is declared, so some characters can render as gibberish.

5 errors were logged to the browser console during Google's test (“ReferenceError: Modernizr is not defined at https://www.prb.co.id/en:2514:3”).

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 0 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
