Mobile performance score: 84
84/100Your mobile performance score is 84. Pages that score under 90 lose visitors before the first paint.
Render-blocking requests
900 ms6 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.
Improve image delivery
600 ms · 259 KiB4 images could be 259 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.
Reduce unused CSS
310 ms · 41 KiBAbout 41 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 310 ms faster on a phone.
Google Tag Manager adds 299 ms
299 msGoogle Tag Manager costs a phone 299 ms of main-thread work and 331 KiB 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.
5 third-party services on the page
5 third-party services load with your homepage (Google Tag Manager, Cloudflare and Cloudflare CDN and others), adding 391 KiB and 317 ms of main-thread time.
5 long tasks on the main thread
5 long tasks block the main thread while loading, the longest for 227 ms. During a long task the page ignores taps.
Reduce unused JavaScript
222 KiBAbout 222 KiB of JavaScript is downloaded but never used on this page.
Legacy JavaScript
150 ms · 35 KiBPolyfills for old browsers add 35 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.
Use efficient cache lifetimes
5 KiB2 files are served with short cache lifetimes, so returning visitors download them again (5 KiB).
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Main-thread work: 1.1 s
A phone's processor spends 1.1 s on main-thread work while loading, 550 ms of it running JavaScript. That is comfortably low.
Server response: 1 ms
1 msYour server sent the HTML in 1 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Time to Interactive: 8.1 s
8.1 sThe page becomes fully interactive after 8.1 s. Good is under 3.8 s.
Largest Contentful Paint: 4.1 s
4.1 sYour largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Buat Bio link di Jagel”.
Speed Index: 3.5 s
3.5 sVisually, the page fills in at 3.5 s (Speed Index). Good is under 3.4 s.
1 image without width and height
1 image have no width and height attributes, so the layout jumps as each one loads.
Not enough real-visitor data yet
Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.
3 checks passed
Total Blocking Time: 160 ms
160 msScripts block the page for only 160 ms while loading. Good is under 200 ms.
Cumulative Layout Shift: 0.002
0.002The layout barely moves while loading (CLS 0.002, good is under 0.1).
First Contentful Paint: 0.8 s
0.8 sThe first text or image appears after 0.8 s, inside the 1.8 s “good” threshold.
Images and page weight
About 0.4 g of CO₂ per visit
0.37 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.37 g of CO₂e: 43.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
1 checks passed
Page weight: 1.3 MB in 67 requests
1.3 MBYour homepage downloads 1.3 MB in 67 requests on a phone: scripts 756 KiB (37), images 449 KiB (16) and stylesheets 67 KiB (8). That is a lean page.
Accessibility
No main landmark
The page has no <main> landmark, so screen-reader users cannot jump straight to the content.
Page should contain a level-one heading (1 element)
Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.
All page content should be contained by landmarks (1 element)
All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.
18 text elements with low contrast
18 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Headings skip levels
Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.
2 checks passed
Every image has alt text
All 14 images in the HTML carry an alt attribute.
20 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 23 WCAG 2.2 A/AA and best-practice rules on the phone render: 20 passed and 3 failed. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
Meta description is short (65 characters)
Your meta description is only 65 characters: “Buat Link-in-bio untuk hubungkan semua bisnismu & perluas koneksi”. 70 to 160 characters is enough to sell the click.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.
9 internal links, 9 external
The homepage links to 9 pages on rumakuko.com and 9 external pages.
7 checks passed
One H1 headline
Your main headline reads: “Satu link untuk semua bisnis dengan jagel.link”.
Title: 61 characters
Your title is a healthy 61 characters: “Cara membuat aplikasi Android sendiri tanpa Coding | Jagel.id”.
Canonical URL set
The canonical URL is https://web.rumakuko.com/cara-membuat-link-bio.
Structured data in place
Structured data found: MobileApplication.
Open Graph tags complete
Open Graph tags are complete, so shared links show a title, description and image.
robots.txt in place
robots.txt is in place and points crawlers to your sitemap.
XML sitemap found
Your XML sitemap is reachable at https://jagel.app/sitemap.xml.
AI search readiness
No Organization structured data
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.
No llms.txt
There is no https://web.rumakuko.com/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.
1 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Other pages
1 linked page is broken
Your homepage links to https://web.rumakuko.com/career, which answers with an error. Visitors hit a dead end and search engines drop it.
1 page without a title
https://web.rumakuko.com/cara-membuat-aplikasi has no <title>, so Google invents the link text in results.
1 page without a meta description
https://web.rumakuko.com/cara-membuat-aplikasi has no meta description, so Google writes the search snippet from whatever text it finds.
1 page without an H1
https://web.rumakuko.com/cara-membuat-aplikasi has no <h1> headline, so visitors and search engines get no clear main topic.
5 internal pages checked

Content and conversion
No call to action on the first screen
On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.
No calls to action
We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.
Thin social proof
Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.
No direct contact details
No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
Only about 17 words
The homepage has only about 17 words of visible text; thin pages give Google and first-time buyers little to go on.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Security, domain, email and software versions
