spark5.de website review

About 463 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 71. Pages that score under 90 lose visitors before the first paint.

41 files are served with short cache lifetimes, so returning visitors download them again (483 KiB).

5 third-party services load with your homepage (Google Tag Manager, Cookiebot and Other Google APIs/SDKs and others), adding 864 KiB and 521 ms of main-thread time.

Google Tag Manager costs a phone 473 ms of main-thread work and 706 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.

6 long tasks block the main thread while loading, the longest for 148 ms. During a long task the page ignores taps.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

About 15 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.

Your largest element takes 6.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “VERNETZT BIS IN DIE WIPFEL Spark 5 ist der Experte, der Ihr…”.

The page becomes fully interactive after 9.2 s. Good is under 3.8 s.

Scripts block taps and scrolling for 270 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.

1 image (37 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 0.37 g of CO₂e: 44.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

Your title is only 25 characters: “Spark 5 GmbH | Startseite”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is only 50 characters: “IT-Dienstleistung - Individuell, agil und flexibel”. 70 to 160 characters is enough to sell the click.

There are 2 <h1> headlines (“” and “Vernetzt bis in die Wipfel”). One clear main headline is easier for people and search engines.

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.

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

The homepage links to 32 pages on spark5.de and 0 external pages.

There is no https://www.spark5.de/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.

https://www.spark5.de/ueber-uns is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://www.spark5.de/datenschutz and https://www.spark5.de/impressum use the same meta description. A description written for each page earns more clicks.

https://www.spark5.de/leistungen/api-anbindung and https://www.spark5.de/kontakt have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 12 pages linked from your homepage and read each the way a search engine does.

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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

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

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 306 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 1 cookie (measured from a US location before any click).

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