Speed

1 to fix100
  • Render-blocking requests

    1.1 s

    8 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

  • Reduce unused CSS

    150 ms · 21 KiB

    About 21 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

  • Font display

    100 ms

    Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

  • 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.

  • Improve image delivery

    5 KiB

    1 image could be 5 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

3 checks passed
  • Mobile performance score: 100

    100/100

    Your mobile performance score is 100 (desktop: 100). That is in Google's “good” band (90 and up).

  • Main-thread work: 0.2 s

    A phone's processor spends 0.2 s on main-thread work while loading, 34 ms of it running JavaScript. That is comfortably low.

  • Server response: 1 ms

    1 ms

    Your server sent the HTML in 1 ms, well inside Google's 600 ms guideline.

Core Web Vitals

3 to fix100
  • Fails Core Web Vitals for real visitors

    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-user TTFB: 1.1 s

    1.1 s

    Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

  • 1 image without width and height

    1 image have no width and height attributes, so the layout jumps as each one loads.

  • Tap response (INP) held steady for real visitors

    +2%

    Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 99 ms to 101 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

11 checks passed
  • Real-user LCP: 1.6 s

    1.6 s

    Real visitors wait 1.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 91 ms

    91 ms

    Real visitors wait 91 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • Real-user CLS: 0.00

    0.00

    For real visitors the layout shifts by 0.00 (75th percentile). Good is under 0.1.

  • Real-user FCP: 1.6 s

    1.6 s

    Real visitors see the first content after 1.6 s (75th percentile). Good is under 1.8 s.

  • Largest content (LCP) got 11% faster for real visitors

    -11%

    Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 0.8 s to 0.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • First Contentful Paint: 1.4 s

    1.4 s

    The first text or image appears after 1.4 s, inside the 1.8 s “good” threshold.

  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

  • Largest Contentful Paint: 1.5 s

    1.5 s

    Your largest element renders in 1.5 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “根據你所在地區的規定,你需要達到法定成年年齡,才可以瀏覽網站內容,請確定你是否成年”.

  • Speed Index: 1.4 s

    1.4 s

    Visually, the page fills in at 1.4 s (Speed Index), inside the 3.4 s “good” threshold.

  • Total Blocking Time: 0 ms

    0 ms

    Scripts block the page for only 0 ms while loading. Good is under 200 ms.

  • Time to Interactive: 1.5 s

    1.5 s

    The page is fully interactive after 1.5 s.

Images and page weight

100
  • 2 images in older formats

    2 images (255 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

  • About 0.04 g of CO₂ per visit

    0.04 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.04 g of CO₂e: 4.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed
  • Page weight: 130 KiB in 19 requests

    130 KiB

    Your homepage downloads 130 KiB in 19 requests on a phone: scripts 62 KiB (8), stylesheets 35 KiB (6) and fonts 18 KiB (1). That is a lean page.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

7 to fixGoogle 7980
  • 3 text elements with low contrast

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

  • 2 images without alt text

    2 images have no alt text, which hurts accessibility and image search.

  • 1 button without a name

    1 button has no accessible name, so screen readers announce just “button”.

  • All page content should be contained by landmarks (5 elements)

    All page content should be contained by landmarks: 5 elements on the page fail this check, rated moderate by axe-core.

  • No main landmark

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

  • Elements with role="dialog" or role="alertdialog" do not have accessible names.

    Elements with role="dialog" or role="alertdialog" do not have accessible names. (1 element).

  • No page language

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

1 checks passed
  • 18 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 21 WCAG 2.2 A/AA and best-practice rules on the phone render: 18 passed and 3 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

8 to fixGoogle 6150
  • robots.txt blocks all crawlers

    Your robots.txt disallows the whole site for every crawler, so search engines are told to stay out.

  • No meta description

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

  • No H1 headline

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

  • Blocked from indexing

    Google's crawler is blocked from indexing this page.

  • No structured data

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

  • No social preview image

    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

    No XML sitemap at https://www.javbus.com/sitemap.xml, so Google discovers your pages only by following links.

  • No favicon declared

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

  • No X (Twitter) card tag

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

  • 32 internal links, 4 external

    The homepage links to 32 pages on javbus.com and 4 external pages.

2 checks passed
  • Title: 32 characters

    Your title is a healthy 32 characters: “Age Verification JavBus - JavBus”.

  • Canonical URL set

    The canonical URL is https://www.javbus.com/doc/driver-verify?referer=https%3A%2F%2Fwww.javbus.com%2F.

AI search readiness

2 to fix37
  • robots.txt blocks 6 AI answer engine crawlers

    6 of 6

    Your robots.txt shuts out ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude search (Claude-SearchBot), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

  • 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://www.javbus.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.

  • Opted out of AI training for 5 crawlers

    robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

Other pages

4 to fix78
  • 9 pages share a title

    https://www.javbus.com/doc/driver-verify?referer=https%3A%2F%2Fwww.javbus.com%2F, /, https://www.javbus.com/en/doc/driver-verify, https://www.javbus.com/ja/doc/driver-verify, https://www.javbus.com/ko/doc/driver-verify and https://www.javbus.com/uncensored and 3 others all use the title “Age Verification JavBus - JavBus”. Search engines can't tell which page to show for a search, so each competes with the others.

  • 8 pages without a meta description

    /, https://www.javbus.com/en/doc/driver-verify, https://www.javbus.com/ja/doc/driver-verify, https://www.javbus.com/ko/doc/driver-verify, https://www.javbus.com/uncensored and https://www.javbus.com/genre and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

  • 5 links to non-canonical URLs

    Your homepage links to 5 pages by a URL that isn't their canonical one, for example /, whose canonical is https://www.javbus.com/doc/driver-verify?referer=https%3A%2F%2Fwww.javbus.com%2F. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

  • 8 pages without an H1

    /, https://www.javbus.com/en/doc/driver-verify, https://www.javbus.com/ja/doc/driver-verify, https://www.javbus.com/ko/doc/driver-verify, https://www.javbus.com/uncensored and https://www.javbus.com/genre and 2 others have no <h1> headline, so visitors and search engines get no clear main topic.

  • 5 pages with very little text

    /, https://www.javbus.com/uncensored, https://www.javbus.com/genre, https://www.javbus.com/uncensored/genre and https://www.javbus.com/actresses have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

  • 14 internal pages checked

    We fetched 14 pages linked from your homepage and read each the way a search engine does.

3 checks passed
  • Linked pages load

    8 pages of 14 loaded without an error (the rest turned automated requests away).

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 8 pages that loaded have a <title>.

Best practices

3 to fixGoogle 9285
  • 2 small tap targets

    2 of 5 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • 1 JavaScript error while loading

    1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 429 ()”.

  • 1 distorted image

    1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

  • 1 low-resolution image

    1 image is served at too low a resolution for sharp phone screens.

1 checks passed
  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

6 to fix36
  • 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.

  • No social proof

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

  • No analytics detected

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

  • 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 54 words

    The homepage has only about 54 words of visible text; thin pages give Google and first-time buyers little to go on.

  • 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.

1 checks passed
  • 2 short forms

    2 short forms (5 fields at most) are right on the homepage.

Privacy and tracking

  • No consent tool detected

    No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

  • 4 other companies contacted

    Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed
  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at javbus.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
