Speed
Improve image delivery
900 ms · 207 KiB4 images could be 207 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 900 ms faster on a phone.
Render-blocking requests
400 ms3 files block the first paint until they finish downloading. Deferring or inlining them could save about 400 ms.
Legacy JavaScript
150 ms · 17 KiBPolyfills for old browsers add 17 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.
Reduce unused JavaScript
26 KiBAbout 26 KiB of JavaScript is downloaded but never used on this page.
Reduce unused CSS
13 KiBAbout 13 KiB of CSS is downloaded but never applied on this page.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Mobile performance score: 91
91/100Your mobile performance score is 91 (desktop: 97). That is in Google's “good” band (90 and up).
Main-thread work: 0.4 s
A phone's processor spends 0.4 s on main-thread work while loading, 54 ms of it running JavaScript. That is comfortably low.
Server response: 3 ms
3 msYour server sent the HTML in 3 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Speed Index: 4.7 s
4.7 sVisually, the page fills in at 4.7 s (Speed Index). Good is under 3.4 s.
Largest Contentful Paint: 3.0 s
3.0 sYour 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 text “Im Rahmen der Verschmelzung der iS Software GmbH mit der ms…”. Most of its time is element render delay (2.5 s).
4 images without width and height
4 images have no width and height attributes, so the layout jumps as each one loads.
Not enough real-visitor data yet
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.
4 checks passed
Time to Interactive: 3.0 s
3.0 sThe page is fully interactive after 3.0 s.
Cumulative Layout Shift: 0
0The layout barely moves while loading (CLS 0, good is under 0.1).
First Contentful Paint: 1.1 s
1.1 sThe first text or image appears after 1.1 s, inside the 1.8 s “good” threshold.
Total Blocking Time: 0 ms
0 msScripts block the page for only 0 ms while loading. Good is under 200 ms.
Images and page weight
3 images in older formats
3 images (206 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.
3 images below the first screen load straight away
3 images further down the page (206 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.
About 0.1 g of CO₂ per visit
0.15 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.15 g of CO₂e: 17.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
2 checks passed
Page weight: 540 KiB in 26 requests
540 KiBYour homepage downloads 540 KiB in 26 requests on a phone: images 405 KiB (10), scripts 88 KiB (11) and HTML 29 KiB (1). That is a lean page.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
1 button without a name
1 button has no accessible name, so screen readers announce just “button”.
6 text elements with low contrast
6 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)
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.
1 link without text
1 visible link has no text or label, so screen readers cannot say where it goes.
2 checks passed
Every image has alt text
All 9 images in the HTML carry an alt attribute.
48 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 52 WCAG 2.2 A/AA and best-practice rules on the phone render: 48 passed and 4 failed. 4 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No H1 headline
There is no <h1>, so neither visitors nor Google get a clear main headline.
Structured data has 1 problem
Structured data found (BreadcrumbList, Organization, WebPage and WebSite) but with 1 problem, for example “Organization: url points at a different host (https://test.is-software.com/)”.
No social preview image
No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.
56 internal links, 10 external
The homepage links to 56 pages on is-software.com and 10 external pages.
5 checks passed
Meta description: 135 characters
Your meta description is 135 characters: “WinEV® Software Lösungen ✓ Beratung und Implementierung ✓ BPO ✓ Cloud Services✓ Genossenschaftsverwaltung ✓ Abrechnung …”.
Title: 56 characters

Canonical URL set
The canonical URL is https://is-software.com/.
robots.txt in place
robots.txt is in place and points crawlers to your sitemap.
XML sitemap found
Your XML sitemap is reachable at https://is-software.com/sitemap_index.xml.
AI search readiness
No llms.txt
There is no https://is-software.com/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.
3 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Organization data: 4 of 6 facts
Your Organization JSON-LD gives name, url, logo and sameAs (social profiles); description and contact details would complete it.
Text is in the HTML
Your server sends the page's text in the HTML (630 words), so crawlers that don't run JavaScript still read it.
Other pages
2 linked pages hidden from search
https://is-software.com/kontakt/ansprechpartner-im-vertrieb and https://is-software.com/agb are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.
15 pages without a meta description
https://is-software.com/events/e-world, https://is-software.com/unternehmen, https://is-software.com/software, https://is-software.com/bpo, https://is-software.com/cloud-services and https://is-software.com/energiewirtschaft and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.
15 pages without an H1
https://is-software.com/events/e-world, https://is-software.com/unternehmen, https://is-software.com/software, https://is-software.com/bpo, https://is-software.com/cloud-services and https://is-software.com/energiewirtschaft and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.
2 pages with very little text
https://is-software.com/events/e-world and https://is-software.com/events 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.

Content and conversion
No call to action on the first screen
On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.
No calls to action
We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.
No social proof
No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.
No analytics detected
No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.
Phone number is not tap-to-call
Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
About 958 words of copy
The homepage carries about 958 words of visible text.
Privacy and tracking
No consent tool detected
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.
1 checks passed
No known trackers before consent
No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
Security, domain, email and software versions
The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at is-software.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
