rubmaps.ch website review

The page has 9,547 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

Reduce initial server response time. Google estimates savings of 572 ms on a phone.

The HTML itself could arrive about 550 ms sooner: redirects, a slow server response or missing compression delay everything after it.

About 139 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

11 files are served with short cache lifetimes, so returning visitors download them again (86 KiB).

21 images could be 418 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 24 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 310 ms faster on a phone.

Your server takes 672 ms to send the HTML. Google recommends under 600 ms; everything else waits for it.

Polyfills for old browsers add 9 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

3 third-party services load with your homepage (Google Tag Manager, Google Analytics and openstreetmap.org), adding 295 KiB and 129 ms of main-thread time.

2 long tasks block the main thread while loading, the longest for 82 ms. During a long task the page ignores taps.

9 KiB could be saved by minifying JavaScript.

6 KiB could be saved by minifying CSS.

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.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.0 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 5.1 s. Good is under 3.8 s.

Visually, the page fills in at 3.8 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 69 ms to 70 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

1 image (33 KiB) is 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.28 g of CO₂e: 33.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Documents must have <title> element to aid in navigation: 1 element on the page fails this check, rated serious by axe-core.

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.

16 tap targets are too small or too close together to hit reliably with a finger.

Tables do not use <caption> instead of cells with the [colspan] attribute to indicate a caption. (1 element).

<td> elements in a large <table> do not have table headers. (1 element).

Your page has no <title>, so Google has to invent the blue link in search results.

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.

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

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.

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

The homepage links to only 3 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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

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.

/law-enforcement and /terms use the same meta description. A description written for each page earns more clicks.

We fetched 2 pages linked from your homepage and read each the way a search engine does.

4 of 6 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 image is served at too low a resolution for sharp phone screens.

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 216 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.

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.
