knisper.io website review

About 659 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.3 s faster on a phone.

18 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 67. Pages that score under 90 lose visitors before the first paint.

34 files are served with short cache lifetimes, so returning visitors download them again (178 KiB).

7 third-party services load with your homepage (Google CDN, Google Tag Manager and SharpSpring and others), adding 1.2 MB and 512 ms of main-thread time.

Polyfills for old browsers add 35 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 350 ms faster on a phone.

About 68 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Google CDN costs a phone 243 ms of main-thread work and 733 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 87 ms. During a long task the page ignores taps.

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

2 KiB could be saved by minifying CSS.

Your largest element takes 11.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Want to know more about Knisper and curious about the advan…”.

The page becomes fully interactive after 11.8 s. Good is under 3.8 s.

The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 4.8 s (Speed Index). Good is under 3.4 s.

1 image have no width and height attributes, so the layout jumps as each one loads.

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 2.0 MB in 62 requests on a phone: scripts 1.1 MB (28), other files 378 KiB (6) and images 263 KiB (4). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.58 g of CO₂e: 69.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Links must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

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 14 characters: “Home - Knisper”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

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

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://knisper.io/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.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://knisper.io/workspace, whose canonical is https://knisper.io/nl/workspace. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 1 page linked from your homepage and read each the way a search engine does.

4 of 7 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 93 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.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

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.

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
