zimmo.net website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 4.8 s.

6 files are served with short cache lifetimes, so returning visitors download them again (676 KiB).

3 images could be 674 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.5 s faster on a phone.

About 279 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.3 s).

Your mobile performance score is 50. Pages that score under 90 lose visitors before the first paint.

3 third-party services load with your homepage (WebsiteBuilder.com, Other Google APIs/SDKs and Azure Web Services), adding 1.8 MB and 770 ms of main-thread time.

WebsiteBuilder.com costs a phone 756 ms of main-thread work and 554 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.

4 long tasks block the main thread while loading, the longest for 270 ms. During a long task the page ignores taps.

Other Google APIs/SDKs costs a phone 14 ms of main-thread work and 889 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.

Azure Web Services costs a phone 0 ms of main-thread work and 446 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.

Polyfills for old browsers add 8 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

About 32 KiB of CSS is downloaded but never applied on this page.

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.

Your largest element takes 9.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The first text or image appears after 5.6 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 9.3 s. Good is under 3.8 s.

Visually, the page fills in at 6.5 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 388 ms in total while the page loads. Good is under 200 ms.

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.

2 images are downloaded at several times the size a phone draws them, for example 60e2cc02883e4089a20ba7c242b0c13e at 7,059 px wide, shown at 80 px. Resized copies would save about 640 KiB.

3 images (689 KiB) are 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 0.53 g of CO₂e: 63.0 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: 3 elements on the page fail this check, rated critical by axe-core.

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 5 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

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.

Your title is only 4 characters: “Home”. 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.

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

Open Graph is missing og:title and og:description, so shared links fall back to guesses.

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 https://zimmo.net/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.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

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 15 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 3 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
