numato.com website review

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 200 ms.

About 28 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 24 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 130 ms faster on a phone.

2 images could be 24 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 files are served with short cache lifetimes, so returning visitors download them again (14 KiB).

Polyfills for old browsers add 11 KiB JavaScript that modern phones do not need.

1 third-party service load with your homepage (Cloudflare), adding 10 KiB and 8 ms of main-thread time.

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.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.4 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.8 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.2 s on a phone. Good is under 1.8 s.

Your largest element takes 3.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Numato Labs - Electronic development tools and products”. Most of its time is element render delay (1.8 s).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.1 s to 2.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.12 g of CO₂e: 14.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 45 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.

Elements with visible text labels do not have matching accessible names. (5 elements).

Your meta description is 170 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 97 pages on numato.com and 7 external pages.

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.

We fetched 15 pages linked from your homepage (of 65 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.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

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.

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

numato.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.

numato.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.

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 383 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.

Opening the homepage sets 2 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 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
