exclaimer.de website review

About 584 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.9 s faster on a phone.

32 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

Your mobile performance score is 65. Pages that score under 90 lose visitors before the first paint.

About 76 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.

4 images could be 35 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

4 long tasks block the main thread while loading, the longest for 117 ms. During a long task the page ignores taps.

Polyfills for old browsers add 29 KiB JavaScript that modern phones do not need.

2 third-party services load with your homepage (Cloudflare and Wistia), adding 12 KiB and 8 ms of main-thread time.

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

1 file is served with short cache lifetimes, so returning visitors download them again (4 KiB).

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Real visitors wait 831 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Your largest element takes 10.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Video poster”.

The page becomes fully interactive after 10.2 s. Good is under 3.8 s.

The first text or image appears after 3.0 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 154 ms to 959 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 983 ms for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 5.6 s (Speed Index). Good is under 3.4 s.

By the Sustainable Web Design model, a visit to your homepage emits about 0.49 g of CO₂e: 59.3 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.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

Your title is 73 characters, so Google will cut it off around 60: “Exclaimer | Email Signature Software for Microsoft 365, Exchange & Google”.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

The homepage links to 47 pages on exclaimer.de and 12 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.

We fetched 15 pages linked from your homepage (of 33 found) and read each the way a search engine does.

1 of 5 tappable elements near the top of the page is smaller than 24 px, hard to hit with a thumb.

Large scripts ship without source maps.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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 864 words of visible text.

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.

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