tuya.com website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

The page has 10,167 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 39. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.5 s on main-thread work while loading, 2.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

173 files are served with short cache lifetimes, so returning visitors download them again (34.8 MB).

2 third-party services load with your homepage (cdn5th.com and tuyacn.com), adding 39.2 MB and 951 ms of main-thread time.

cdn5th.com costs a phone 951 ms of main-thread work and 39.2 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.

15 long tasks block the main thread while loading, the longest for 2.1 s. During a long task the page ignores taps.

About 84 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

14 images could be 358 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 300 KiB of JavaScript is downloaded but never used on this page.

Polyfills for old browsers add 33 KiB JavaScript that modern phones do not need.

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.

The page becomes fully interactive after 35.8 s. Good is under 3.8 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 text “Create AI-Driven Smart Products”.

Scripts block taps and scrolling for 1.9 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 9.0 s (Speed Index). Good is under 3.4 s.

Real visitors wait 2.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 271 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.6 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.7 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.8 s to 2.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 39.3 MB in 184 requests on a phone: media 32.4 MB (3), images 5.0 MB (126) and scripts 1.5 MB (37). Under 2 MB keeps phones on slow connections fast.

11 images are downloaded at several times the size a phone draws them, for example dbb34ada9e14ec50a2a0.png at 3,000 px wide, shown at 100 px. Resized copies would save about 1,012 KiB.

24 images (1.7 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.

24 images further down the page (1.6 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 11.13 g of CO₂e: 1335.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 117 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

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

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

Your meta description is 183 characters; Google truncates after about 160, so the end of your pitch is cut.

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

Open Graph is missing og:title and og:description, so shared links fall back to guesses.

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

The homepage links to 89 pages on tuya.com and 69 external pages.

https://tuya.com/platform/productdev/tuyaos, https://tuya.com/platform/productdev/mcu-standard-protocol, https://tuya.com/platform/productdev/connect-sub-devices, https://tuya.com/platform/appdev/app-sdk, https://tuya.com/platform/appdev/oemapp and https://tuya.com/platform/appdev/panel-miniapp and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://tuya.com/platform/appdev/app-sdk, https://tuya.com/platform/growth/data-intelligent-operation and https://tuya.com/platform/growth/data-center took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 39 found) and read each the way a search engine does.

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

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

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 870 words of visible text.

Opening the homepage sets 7 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
