artmasterclass.com website review

A phone's processor spends 4.1 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,295 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

29 images could be 2.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 537 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 590 ms faster on a phone.

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (vitals.app, Google Tag Manager and Shopify and others), adding 2.0 MB and 792 ms of main-thread time.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

vitals.app costs a phone 222 ms of main-thread work and 394 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.

Google Tag Manager costs a phone 220 ms of main-thread work and 348 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 118 ms of main-thread work and 653 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.

tidio.co costs a phone 71 ms of main-thread work and 519 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.

10 long tasks block the main thread while loading, the longest for 198 ms. During a long task the page ignores taps.

7 files are served with short cache lifetimes, so returning visitors download them again (174 KiB).

About 60 KiB of CSS is downloaded but never applied on this page.

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

8 KiB could be saved by minifying CSS.

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.

Visually, the page fills in at 19.0 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 22.2 s. Good is under 3.8 s.

The first text or image appears after 3.7 s on a phone. Good is under 1.8 s.

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

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

Your largest element takes 3.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies to improve your experience and track website…”. Most of its time is element render delay (2.6 s).

Scripts block taps and scrolling for 415 ms in total while the page loads. Good is under 200 ms.

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

Your homepage downloads 8.0 MB in 241 requests on a phone: images 3.1 MB (41), media 2.0 MB (3) and scripts 1.7 MB (85). Under 2 MB keeps phones on slow connections fast.

13 images further down the page (1.9 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

ChatGPT_Image_Sep_4_2026_04_50_52_PM.png 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 2.26 g of CO₂e: 271.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

Alternative text of images should not be repeated as text: 33 elements on the page fail this check, rated minor by axe-core.

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

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

Headings should not be empty: 2 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h3 → h6 and h2 → h6), which makes the page harder to scan with a screen reader.

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

Your title is 82 characters, so Google will cut it off around 60: “Art Masterclass California-Discover Your Artistic Inner Self – Art Masterclass USA”.

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

Your meta description is 305 characters; Google truncates after about 160, so the end of your pitch is cut.

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

2 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 431 pages on artmasterclass.com and 20 external pages.

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.

/collections/book-a-workshop/workshop and /collections/california-workshops have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /collections/book-a-workshop/workshop, whose canonical is /collections/book-a-workshop. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/collections/book-a-workshop/workshop has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 178 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_TUNNEL_CONNECTION_FAILED”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

artmasterclass.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

artmasterclass.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage shows no opening hours. If customers visit or call, show when.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 833 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and Meta Pixel and 2 mores (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 22 cookies, 2 of them by other companies (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 29 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
