Speed

3 to fix86
  • Mobile performance score: 86

    86/100

    Your mobile performance score is 86. Pages that score under 90 lose visitors before the first paint.

  • Render-blocking requests

    800 ms

    4 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.

  • Improve image delivery

    342 KiB

    6 images could be 342 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Use efficient cache lifetimes

    50 ms · 241 KiB

    28 files are served with short cache lifetimes, so returning visitors download them again (241 KiB).

  • Font display

    50 ms

    Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

  • 3 third-party services on the page

    3 third-party services load with your homepage (Cloudflare, Google Fonts and pvpbet.io), adding 341 KiB and 12 ms of main-thread time.

  • Reduce unused CSS

    26 KiB

    About 26 KiB of CSS is downloaded but never applied on this page.

  • Legacy JavaScript

    10 KiB

    Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

  • 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.

2 checks passed
  • Main-thread work: 0.9 s

    A phone's processor spends 0.9 s on main-thread work while loading, 123 ms of it running JavaScript. That is comfortably low.

  • Server response: 102 ms

    102 ms

    Your server sent the HTML in 102 ms, well inside Google's 600 ms guideline.

Core Web Vitals

6 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 FCP: 2.0 s

    2.0 s

    Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

  • 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.

  • Speed Index: 5.4 s

    5.4 s

    Visually, the page fills in at 5.4 s (Speed Index). Good is under 3.4 s.

  • Largest Contentful Paint: 3.5 s

    3.5 s

    Your largest element takes 3.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “banner five88”.

  • 1 image without width and height

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

7 checks passed
  • Real-user LCP: 2.1 s

    2.1 s

    Real visitors wait 2.1 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 115 ms

  • Time to Interactive: 3.5 s

    3.5 s

    The page is fully interactive after 3.5 s.

  • First Contentful Paint: 1.7 s

    1.7 s

    The first text or image appears after 1.7 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).

  • Total Blocking Time: 0 ms

    0 ms

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

Images and page weight

100
  • 1 image in older formats

    1 image (255 KiB) is 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 0.3 g of CO₂ per visit

    0.30 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.30 g of CO₂e: 35.4 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: 1.0 MB in 42 requests

    1.0 MB

    Your homepage downloads 1.0 MB in 42 requests on a phone: images 776 KiB (17), scripts 90 KiB (10) and fonts 81 KiB (4). 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

10 to fixGoogle 7987
  • 20 text elements with low contrast

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

  • Links look like plain text

    1 link inside paragraphs relies on colour alone to stand out.

  • Scrollable region must have keyboard access (1 element)

    Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

  • 1 image without alt text

    1 image has no alt text, which hurts accessibility and image search.

  • Main landmark should not be contained in another landmark (1 element)

    Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

  • Document should not have more than one main landmark (1 element)

    Document should not have more than one main landmark: 1 element on the page fails this check, rated moderate by axe-core.

  • Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)

    Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 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.

  • 1 link without text

    1 visible link has no text or label, so screen readers cannot say where it goes.

  • 1 tap target too small

    1 tap target is too small or too close together to hit reliably with a finger.

  • Headings skip levels

    Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

  • <td> elements in a large <table> do not have table headers.

    <td> elements in a large <table> do not have table headers. (2 elements).

1 checks passed
  • 44 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 54 WCAG 2.2 A/AA and best-practice rules on the phone render: 44 passed and 10 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 9295
  • No structured data

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

  • No favicon declared

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

  • 37 internal links, 9 external

    The homepage links to 37 pages on refermo.co and 9 external pages.

7 checks passed
  • Meta description: 142 characters

    Your meta description is 142 characters: “Truy cập FIVE88.COM 2026 bản chuẩn. Chuyên cá cược thể thao, bóng đá, casino trực tuyến. Hệ thống nạp rút tự động 24/7,…”.

  • One H1 headline

    Your main headline reads: “FIVE88 | Đánh Giá Tổng Quan Nhà Cái Cá Cược Uy Tín Nhất 2026”.

  • Title: 49 characters

    Your title is a healthy 49 characters: “FIVE88.COM 2026 - Cổng Game Cá Cược Thể Thao Số 1”.

  • Canonical URL set

    The canonical URL is https://five88z.net/vi-vn/.

  • 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://five88z.net/sitemap_index.xml.

AI search readiness

1 to fix88
  • 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://five88z.net/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.

2 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.

  • Text is in the HTML

    Your server sends the page's text in the HTML (2,473 words), so crawlers that don't run JavaScript still read it.

Best practices

1 to fixGoogle 10093

    2 of 9 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

Content and conversion

4 to fix30
  • 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 direct contact details

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

  • 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.

  • About 1,992 words of copy

    The homepage carries about 1,992 words of visible text.

1 checks passed
  • Analytics in place

    Analytics detected: Cloudflare Web Analytics.

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.

  • 5 other companies contacted

    Loading the homepage contacts 5 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 refermo.co, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
