Speed

11 to fix42
  • Render-blocking requests

    1.8 s

    28 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

  • Mobile performance score: 42

    42/100

    Your mobile performance score is 42. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

  • Main-thread work: 5.2 s

    A phone's processor spends 5.2 s on main-thread work while loading, 3.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 3,863 HTML elements

    The page has 3,863 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Reduce unused JavaScript

    300 ms · 985 KiB

    About 985 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Shopify and Yotpo and others), adding 2.1 MB and 971 ms of main-thread time.

  • Improve image delivery

    500 ms · 426 KiB

    22 images could be 426 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 500 ms faster on a phone.

  • Use efficient cache lifetimes

    200 ms · 598 KiB

    23 files are served with short cache lifetimes, so returning visitors download them again (598 KiB).

  • Google Tag Manager adds 289 ms

    289 ms

    Google Tag Manager costs a phone 289 ms of main-thread work and 496 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.

  • Shopify adds 201 ms

    201 ms

    Shopify costs a phone 201 ms of main-thread work and 697 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.

  • Yotpo adds 184 ms

    184 ms

    Yotpo costs a phone 184 ms of main-thread work and 358 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.

  • Minify JavaScript

    150 ms · 243 KiB

    243 KiB could be saved by minifying JavaScript.

  • 13 long tasks on the main thread

    13 long tasks block the main thread while loading, the longest for 227 ms. During a long task the page ignores taps.

  • Legacy JavaScript

    55 KiB

    Polyfills for old browsers add 55 KiB JavaScript that modern phones do not need.

  • Reduce unused CSS

    28 KiB

    About 28 KiB of CSS is downloaded but never applied on this page.

  • 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.

  • Forced reflow

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

  • Minify CSS

    4 KiB

    4 KiB could be saved by minifying CSS.

1 checks passed
  • Server response: 25 ms

    25 ms

    Your server sent the HTML in 25 ms, well inside Google's 600 ms guideline.

Core Web Vitals

10 to fix67
  • 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.

  • Time to Interactive: 27.2 s

    27.2 s

    The page becomes fully interactive after 27.2 s. Good is under 3.8 s.

  • Largest Contentful Paint: 8.8 s

    8.8 s

    Your largest element takes 8.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

  • First Contentful Paint: 3.5 s

    3.5 s

    The first text or image appears after 3.5 s on a phone. Good is under 1.8 s.

  • Total Blocking Time: 612 ms

    612 ms

    Scripts block taps and scrolling for 612 ms in total while the page loads. Good is under 200 ms.

  • Real-user LCP: 2.6 s

    2.6 s

    Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • 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: 1.0 s

    1.0 s

    Real visitors wait 1.0 s for your server to start answering (75th percentile). Good is under 800 ms.

  • Speed Index: 5.5 s

    5.5 s

    Visually, the page fills in at 5.5 s (Speed Index). Good is under 3.4 s.

  • Cumulative Layout Shift: 0.158

    0.158

    The layout shifts by 0.158 while loading, so content jumps under the reader's thumb. Good is under 0.1.

4 checks passed
  • Real-user INP: 180 ms

    180 ms

    Real visitors wait 180 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.

  • Tap response (INP) got 35% faster for real visitors

    -35%

    Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 335 ms to 221 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) got 12% faster for real visitors

    -12%

    Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.6 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Images and page weight

3 to fix62
  • Page weight: 5.0 MB in 427 requests

    5.0 MB

    Your homepage downloads 5.0 MB in 427 requests on a phone: scripts 2.3 MB (108), images 1.2 MB (65) and other files 1,012 KiB (194). Under 2 MB keeps phones on slow connections fast.

  • An image on the first screen is lazy-loaded

    Pro_Flashsale-11-11_Mobile-Banner.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

  • 21 images below the first screen load straight away

    21 images further down the page (804 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • About 1.4 g of CO₂ per visit

    1.42 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.42 g of CO₂e: 170.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 checks passed
  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images are sized for phones

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

Accessibility

6 to fixGoogle 8392
  • Certain ARIA roles must contain particular children (1 element)

    Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical 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.

  • 2 images without alt text

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

  • All page content should be contained by landmarks (3 elements)

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

  • 3 links without text

    3 visible links have no text or label, so screen readers cannot say where they go.

  • 1 form field without a label

    1 form field has no label, so screen readers announce an empty box and autofill guesses.

  • Headings skip levels

    Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

  • Elements with visible text labels do not have matching accessible names.

    Elements with visible text labels do not have matching accessible names. (1 element).

1 checks passed
  • 53 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 59 WCAG 2.2 A/AA and best-practice rules on the phone render: 53 passed and 6 failed. 4 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

3 to fixGoogle 8584
  • No H1 headline

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

  • No structured data

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

  • 2 links crawlers can't follow

    2 links have no real href, so search engines can't follow them.

  • 283 internal links, 8 external

    The homepage links to 283 pages on ta-to.com and 8 external pages.

6 checks passed
  • Meta description: 153 characters

    Your meta description is 153 characters: “ร้านค้าคอนแทคเลนส์ยอดนิยมของประเทศไทย! จัดส่งฟรีทั่วประเทศ ราคาถูกที่สุด เลือกคอนแทคเลนส์ Acuvue, Bausch + Lomb, Alcon …”.

  • Title: 63 characters

    Your title is a healthy 63 characters: “TA-TO.com: ร้านคอนแทคเลนส์อันดับ 1 ในไทย | ราคาถูกสุด+จัดส่งฟรี”.

  • Canonical URL set

    The canonical URL is https://www.ta-to.com/.

  • 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://www.ta-to.com/sitemap.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.

3 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 (1,757 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes https://www.ta-to.com/llms.txt (6 KiB, 8 links), a plain-text guide to the site for AI tools.

Other pages

2 to fix90
  • 1 page without a meta description

    https://www.ta-to.com/pages/rewards has no meta description, so Google writes the search snippet from whatever text it finds.

  • 4 pages without an H1

    https://www.ta-to.com/collections/all, https://www.ta-to.com/pages/rewards, https://www.ta-to.com/collections/naturelle and https://www.ta-to.com/products/1-day-acuvue-moist have no <h1> headline, so visitors and search engines get no clear main topic.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 87 found) and read each the way a search engine does.

5 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Titles are unique

    Every page we checked has its own title.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 15 pages that loaded have a <title>.

Best practices

5 to fixGoogle 5081
  • 12 small tap targets

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

  • Deprecated browser APIs

    The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

  • 1 third-party cookie

    1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

  • 4 JavaScript errors while loading

    4 errors were logged to the browser console while the page loaded, for example “Unexpected token ';'”.

  • 1 distorted image

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

  • Browser-reported issues

    Chrome logged issues while loading the page (“Cookie”).

1 checks passed
  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

1 to fix86

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

  • About 720 words of copy

    The homepage carries about 720 words of visible text.

6 checks passed
  • 36 calls to action

    The homepage has 36 calls to action, for example “Shop All”, “Clear Contact Lenses” and “Shop All Clear Contacts”.

  • 3 short forms

  • Risk reducer mentioned

    A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.

Privacy and tracking

1 to fix
  • 5 trackers load before any consent

    5

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

  • 28 cookies set on arrival

    28

    Opening the homepage sets 28 cookies, 1 of them by other companies (measured from a US location before any click).

  • 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.

  • 44 other companies contacted

    Loading the homepage contacts 44 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

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 ta-to.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
