4knapp.com website review

Your mobile performance score is 81. Pages that score under 90 lose visitors before the first paint.

About 262 KiB of JavaScript is downloaded but never used on this page.

4 third-party services load with your homepage (Google Tag Manager, Smartlook and Google Fonts and others), adding 263 KiB and 176 ms of main-thread time.

About 160 KiB of CSS is downloaded but never applied on this page.

5 long tasks block the main thread while loading, the longest for 104 ms. During a long task the page ignores taps.

5 files are served with short cache lifetimes, so returning visitors download them again (76 KiB).

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.

The layout shifts by 0.318 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The page becomes fully interactive after 6.0 s. Good is under 3.8 s.

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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.53 g of CO₂e: 63.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 37 elements on the page fail this check, rated moderate by axe-core.

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

1 visible link has no text or label, so screen readers cannot say where it goes.

Headings skip levels (h1 → h4 and h3 → h5), which makes the page harder to scan with a screen reader.

The homepage links to 72 pages on 4knapp.com and 6 external pages.

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.

Your homepage links to /blo/home%20, /blo/home-tax, /blo/home-two, /blo/home-three, /blo/home-four and /blo/home-five and 7 others, which answer with an error. Visitors hit a dead end and search engines drop them.

/case-categories/services-we-serve-to-all-over-the-world-3 and /case-categories/services-we-serve-to-all-over-the-world-2 all use the title “Services we serve to all over the world - 4KNAAP”. Search engines can't tell which page to show for a search, so each competes with the others.

/case-categories/services-we-serve-to-all-over-the-world-3 and /case-categories/services-we-serve-to-all-over-the-world-2 have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 23 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

Large scripts ship without source maps.

13 links from your homepage to your own site are broken, for example https://4knapp.com/blo/home%20 (404).

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

4knapp.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

4knapp.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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.

The homepage carries about 266 words of visible text.

DMARC is set to p=none, so mail pretending to be 4knapp.com is still delivered. Add a report address, check the reports, then move to quarantine.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads 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 2 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
