donghia.com website review

About 797 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

15 files are served with short cache lifetimes, so returning visitors download them again (581 KiB).

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

A phone's processor spends 4.7 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

About 186 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, nice-incontact.com and visenze.com and others), adding 1.3 MB and 624 ms of main-thread time.

Google Tag Manager costs a phone 316 ms of main-thread work and 520 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 350 ms).

The page has 2,119 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

nice-incontact.com costs a phone 137 ms of main-thread work and 351 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.

7 long tasks block the main thread while loading, the longest for 142 ms. During a long task the page ignores taps.

6 images could be 120 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

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 19.4 s. Good is under 3.8 s.

Your largest element takes 6.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 6.9 s (Speed Index). Good is under 3.4 s.

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

Real visitors wait 1.4 s for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 279 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 118 ms to 124 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.0 MB in 312 requests on a phone: scripts 1.9 MB (234), images 434 KiB (19) and HTML 205 KiB (4). Under 2 MB keeps phones on slow connections fast.

skyline_1.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).

1 image is downloaded at several times the size a phone draws it, for example video_1.jpg at 1,920 px wide, shown at 390 px. Resized copies would save about 41 KiB.

2 images further down the page (91 KiB) 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 0.86 g of CO₂e: 102.8 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: 1 element on the page fails this check, rated critical by axe-core.

1 dropdown has no label.

ARIA commands must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

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

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

Your title is only 16 characters: “Donghia | Kravet”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Your meta description is 358 characters; Google truncates after about 160, so the end of your pitch is cut.

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

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

The homepage links to 412 pages on donghia.com and 15 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 /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.

robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers, which the crawlers above handle.

/kravet, /contract, /carpet-visualizer, /sectional-visualizer, /advanced-color-search and /barcode_scanner and 3 others use the same meta description. A description written for each page earns more clicks.

/kravet, /lee-jofa, /brunschwig-fils, /gpj-baker, /contract and /kravet-furniture-options and 1 other have no <h1> headline, so visitors and search engines get no clear main topic.

/barcode_scanner 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 42 found) and read each the way a search engine does.

7 of 18 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 1 deprecated browser API that will stop working in future browsers (“`<source src>` with a `<picture>` parent is invalid and therefore ignored. Please use `<source srcs…”).

2 images are served at too low a resolution for sharp phone screens.

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

Large scripts ship without source maps.

http://donghia.com does not redirect to https, so some visitors land on the insecure version.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Opening https://donghia.com goes through 3 redirects before the homepage loads.

1 link go through two or more redirects, for example https://www.kravet.com/custom-bedding/.

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.

kravet.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.

kravet.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.

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

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 296 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

donghia.com has no MX record, so it receives no email. SPF -all and DMARC reject still matter: they stop others sending mail as you.

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 and Google Tag Manager (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 23 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
