ais.th website review

22 files are served with short cache lifetimes, so returning visitors download them again (1.3 MB).

About 1.8 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.7 s faster on a phone.

Google Tag Manager costs a phone 4.4 s of main-thread work and 2.6 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

Your mobile performance score is 33. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 8.8 s on main-thread work while loading, 6.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Facebook and TikTok and others), adding 3.4 MB and 5.3 s of main-thread time.

About 149 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 910 ms faster on a phone.

20 long tasks block the main thread while loading, the longest for 664 ms. During a long task the page ignores taps.

38 KiB could be saved by minifying JavaScript.

Facebook costs a phone 279 ms of main-thread work and 289 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.

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

Polyfills for old browsers add 50 KiB JavaScript that modern phones do not need.

1 image could be 38 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

Your largest element takes 11.8 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 15.9 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 5.1 s in total while the page loads. Good is under 200 ms.

The page becomes fully interactive after 29.7 s. Good is under 3.8 s.

Real visitors wait 300 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 371 ms to 425 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 3.0 s to 2.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.6 MB in 170 requests on a phone: scripts 4.2 MB (65), stylesheets 140 KiB (4) and other files 94 KiB (64). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.29 g of CO₂e: 155.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

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 XML sitemap at https://www.ais.th/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to only 2 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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

1 link has no real href, so search engines can't follow it.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

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 /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.

/cover-page/iphone-duo and /consumers all use the title “AIS เครือข่ายที่ดีที่สุดสำหรับทุกเจเนอเรชัน”. Search engines can't tell which page to show for a search, so each competes with the others.

/consumers/promotions/recommend/apple/iphone-duo and /consumers have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 2 pages linked from your homepage and read each the way a search engine does.

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

Large scripts ship without source maps.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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 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 1 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.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and Meta Pixel and 3 mores (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 23 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 28 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
