gmschoollab.com website review

About 214 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

20 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.0 s.

The page has 4,055 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 75. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 285 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.

35 KiB could be saved by minifying JavaScript.

A phone's processor spends 3.1 s on main-thread work while loading, 851 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

5 third-party services load with your homepage (Shopify, Google Tag Manager and personalizer.io and others), adding 637 KiB and 363 ms of main-thread time.

3 long tasks block the main thread while loading, the longest for 109 ms. During a long task the page ignores taps.

1 image could be 92 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.

2 files are served with short cache lifetimes, so returning visitors download them again (3 KiB).

Your largest element takes 7.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 7.5 s. Good is under 3.8 s.

Visually, the page fills in at 3.5 s (Speed Index). Good is under 3.4 s.

Your homepage downloads 2.6 MB in 259 requests on a phone: other files 1.3 MB (105), scripts 729 KiB (70) and images 243 KiB (53). Under 2 MB keeps phones on slow connections fast.

FullSizeRender_e69aa2a4-32d4-487b-9266-301887821452.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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.74 g of CO₂e: 89.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h1 → h3 and h3 → h5), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (2 elements).

Your title is only 13 characters: “GM School Lab”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is only 30 characters: “Stationery Store in Phnom Penh”. 70 to 160 characters is enough to sell the click.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

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

The homepage links to 189 pages on gmschoollab.com and 22 external pages.

Your Organization JSON-LD is missing logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

Your homepage links to https://gmschoollab.com/pages/about-us, which answers with an error. Visitors hit a dead end and search engines drop it.

https://gmschoollab.com/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://gmschoollab.com/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://gmschoollab.com/pages/contact, https://gmschoollab.com/customer_authentication/redirect, https://gmschoollab.com/collections/all, https://gmschoollab.com/products/bag-december, https://gmschoollab.com/products/copy-cup13-blue-cat-stainless-cup-1 and https://gmschoollab.com/products/copy-cup09-stainless-cup-1200ml and 7 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://gmschoollab.com/pages/contact, https://gmschoollab.com/customer_authentication/redirect, https://gmschoollab.com/collections/all and https://gmschoollab.com/collections/keychain have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 80 found) and read each the way a search engine does.

5 of 14 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

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

The homepage has only about 89 words of visible text; thin pages give Google and first-time buyers little to go on.

Before a visitor clicks anything, the page loads Google Tag Manager (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.

Opening the homepage sets 6 cookies (measured from a US location before any click).

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.

Loading the homepage contacts 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
