obagi.co.th website review

About 642 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.0 s faster on a phone.

59 files are served with short cache lifetimes, so returning visitors download them again (654 KiB).

Your mobile performance score is 67. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, mbirdcdn.net and Shopify and others), adding 1.4 MB and 454 ms of main-thread time.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

Google Tag Manager costs a phone 348 ms of main-thread work and 632 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.

A phone's processor spends 2.0 s on main-thread work while loading, 872 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

mbirdcdn.net costs a phone 32 ms of main-thread work and 409 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 costs a phone 31 ms of main-thread work and 300 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.

1 image could be 171 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

4 long tasks block the main thread while loading, the longest for 139 ms. During a long task the page ignores taps.

75 KiB could be saved by minifying JavaScript.

About 14 KiB of CSS is downloaded but never applied on this page.

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.

Your largest element takes 12.6 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 13.8 s. Good is under 3.8 s.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 3.7 MB in 309 requests on a phone: scripts 1.4 MB (101), other files 1.0 MB (138) and images 827 KiB (45). Under 2 MB keeps phones on slow connections fast.

OBAGI_JUN2025_REVAMP_BAU_HOMEPAGE_1920x1080_2_1080x.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 1.04 g of CO₂e: 124.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 5 elements on the page fail this check, rated critical by axe-core.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

Some list items are not inside a list.

3 tap targets are too small or too close together to hit reliably with a finger.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 7 elements on the page fail this check, rated moderate by axe-core.

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.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

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

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

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

Your title is only 24 characters: “Obagi Medical - Thailand”. Between 30 and 65 characters leaves room to say what you do and for whom.

Structured data found ((untyped), Organization and WebSite) but with 2 problems, for example “untyped block: missing @context (expected "https://schema.org")”.

The homepage links to 73 pages on obagi.co.th and 9 external pages.

There is no https://obagi.co.th/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.

https://obagi.co.th/blogs/dev-blog, https://obagi.co.th/pages/physician-finder and https://obagi.co.th/collections/all have no meta description, so Google writes the search snippet from whatever text it finds.

https://obagi.co.th/pages/contact has no <h1> headline, so visitors and search engines get no clear main topic.

https://obagi.co.th/pages/contact, https://obagi.co.th/collections/all and https://obagi.co.th/collections/bestsellers 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.

We fetched 15 pages linked from your homepage (of 44 found) and read each the way a search engine does.

10 of 25 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.

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 175 words of visible text; thin pages give Google and first-time buyers little to go on.

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 and 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 12 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 19 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
