gruber.com website review

20 files block the first paint until they finish downloading. Deferring or inlining them could save about 6.8 s.

About 995 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 5.1 s faster on a phone.

About 440 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

Your mobile performance score is 59 (desktop: 77). Pages that score under 90 lose visitors before the first paint.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

28 KiB could be saved by minifying CSS.

3 images could be 44 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

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

The first text or image appears after 7.1 s on a phone. Good is under 1.8 s.

Your largest element takes 8.3 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 7.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 8.3 s. Good is under 3.8 s.

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 2.6 MB in 46 requests on a phone: stylesheets 1.1 MB (18), fonts 749 KiB (4) and scripts 687 KiB (16). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.75 g of CO₂e: 90.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 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.

The robots meta tag says “noindex, nofollow”: Google is told not to list this page at all.

No meta description, so Google writes its own snippet from whatever text it finds.

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

Google's crawler is blocked from indexing this page.

Your title is 86 characters, so Google will cut it off around 60: “Gruber Industries – Collection of synergistic businesses engaged in high-tech ventures”.

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

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

No XML sitemap at https://gruber.com/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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

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.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

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

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.

gruber.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.

gruber.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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

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

The homepage has only about 225 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

DMARC is set to p=none, so mail pretending to be gruber.com is still delivered. Reports are on, so moving to quarantine is the next step.

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.

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.
