12thwonder.com website review

Google CDN costs a phone 1.6 s of main-thread work and 1.1 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.

Your mobile performance score is 47. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 9.5 s on main-thread work while loading, 4.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Vimeo and others), adding 3.0 MB and 3.0 s of main-thread time.

About 2.0 MB of JavaScript is downloaded but never used on this page.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

Google Tag Manager costs a phone 777 ms of main-thread work and 480 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.

20 long tasks block the main thread while loading, the longest for 486 ms. During a long task the page ignores taps.

Vimeo costs a phone 338 ms of main-thread work and 1.1 MB 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.

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

2 images could be 62 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 100 ms faster on a phone.

12 files are served with short cache lifetimes, so returning visitors download them again (111 KiB).

About 56 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 50 ms faster on a phone.

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.

Real visitors see the first content after 3.6 s (75th percentile). Good is under 1.8 s.

The page becomes fully interactive after 26.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 2.8 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 7.0 s (Speed Index). Good is under 3.4 s.

Your largest element takes 4.6 s to render on a phone. Google's threshold for “good” is 2.5 s.

Real visitors wait 3.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.12 (75th percentile). Good is under 0.1.

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 151 ms to 177 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 3.6 s to 3.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.4 MB in 152 requests on a phone: images 3.0 MB (62), scripts 2.6 MB (55) and other files 365 KiB (15). Under 2 MB keeps phones on slow connections fast.

avtar2.B6FovlG3.png weighs 603 KiB. On a phone connection a single image that size takes seconds.

5 images are downloaded at several times the size a phone draws them, for example casestudy_how_a_north_american_oem_prod_7373bdadfa.jpg at 1,920 px wide, shown at 289 px. Resized copies would save about 660 KiB.

10 images (1.8 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

10 images further down the page (1.3 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.82 g of CO₂e: 218.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 3 elements on the page fail this check, rated critical by axe-core.

1 dropdown has no label.

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

1 frame has no title, so screen-reader users cannot tell what it contains.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

1 tap target is too small or too close together to hit reliably with a finger.

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

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

There are 2 <h1> headlines (“We make AI work in the industries where it's hard…” and “We make AI work in the industries where it's hard…”). One clear main headline is easier for people and search engines.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 57 pages on 12thwonder.com and 6 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.

There is no https://12thwonder.com/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://12thwonder.com/market-research has 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 21 found) and read each the way a search engine does.

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

2 errors were logged to the browser console while the page loaded, for example “%c%d font-size:0;color:transparent NaN”.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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

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

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 1,525 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Microsoft Clarity (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 8 cookies, 3 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 17 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
