hidden.io website review

About 249 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

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

44 images could be 1.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 750 ms faster on a phone.

4 files are served with short cache lifetimes, so returning visitors download them again (96 KiB).

7 third-party services load with your homepage (Google Tag Manager, herefish.com and bullhornstaffing.com and others), adding 2.4 MB and 223 ms of main-thread time.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

A phone's processor spends 2.3 s on main-thread work while loading, 975 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

sourceflow.co.uk costs a phone 0 ms of main-thread work and 2.0 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.

About 25 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

6 long tasks block the main thread while loading, the longest for 167 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 12 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

5 KiB could be saved by minifying JavaScript.

Your largest element takes 11.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “HIDDEN by DNA”. Most of its time is resource load duration (5.2 s).

The page becomes fully interactive after 11.9 s. Good is under 3.8 s.

Visually, the page fills in at 8.0 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.41 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Scripts block taps and scrolling for 320 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

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

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 3.2 MB in 117 requests on a phone: images 2.0 MB (47), scripts 666 KiB (33) and other files 389 KiB (29). Under 2 MB keeps phones on slow connections fast.

93e7kc79rfv1lkw3tqlvfkvr9mw3 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).

6 images are downloaded at several times the size a phone draws them, for example qmh1er9l4g2m20f5b8qv0k0ck8jn at 1,000 px wide, shown at 220 px. Resized copies would save about 206 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.91 g of CO₂e: 109.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 11 elements on the page fail this check, rated moderate by axe-core.

Headings skip levels (h1 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

Your title is only 27 characters: “HIDDEN by DNA | DNA Recruit”. 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.

There are 7 <h1> headlines (“”, “DNA Grow” and “DNA Adapt”). One clear main headline is easier for people and search engines.

Your meta description is 233 characters; Google truncates after about 160, so the end of your pitch is cut.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

The homepage links to 92 pages on hidden.io and 5 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.

/submit-your-brief, /register-your-cv, /testimonials, /jobs, /sectors and /sectors/client-services use the same meta description. A description written for each page earns more clicks.

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

/sectors/client-services and /sectors/client-side took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 46 found) and read each the way a search engine does.

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

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.

dnarecruit.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.

dnarecruit.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.

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.

There is no form on the homepage, so every lead has to click through to another page first.

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 451 words of visible text.

hidden.io has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

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.

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). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 5 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 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
