appeon.com website review

About 399 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.1 s faster on a phone.

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

36 files are served with short cache lifetimes, so returning visitors download them again (287 KiB).

Your mobile performance score is 58 (desktop: 85). Pages that score under 90 lose visitors before the first paint.

5 third-party services load with your homepage (Olark, Google Tag Manager and Hotjar and others), adding 979 KiB and 893 ms of main-thread time.

4 images could be 603 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

About 98 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Olark costs a phone 358 ms of main-thread work and 440 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.

Google Tag Manager costs a phone 333 ms of main-thread work and 446 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.

16 KiB could be saved by minifying JavaScript.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

9 long tasks block the main thread while loading, the longest for 145 ms. During a long task the page ignores taps.

Desktop scores 85 but mobile only 58. A gap that wide usually means heavy scripts and images that hit phones hardest.

Polyfills for old browsers add 8 KiB JavaScript that modern phones do not need.

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

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 1.9 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 15.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Cloud App Development, Simplified. A simpler, faster, open-…”.

The first text or image appears after 6.1 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 15.3 s. Good is under 3.8 s.

Visually, the page fills in at 6.4 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.6 s (75th percentile). Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 134 ms to 148 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.2 MB in 67 requests on a phone: scripts 1.0 MB (24), images 859 KiB (19) and fonts 242 KiB (4). Under 2 MB keeps phones on slow connections fast.

5 images further down the page (816 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

3 images are downloaded at several times the size a phone draws them, for example news02-3.webp at 1,312 px wide, shown at 186 px. Resized copies would save about 365 KiB.

2 images (315 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.64 g of CO₂e: 76.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 tap targets are too small or too close together to hit reliably with a finger.

2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

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 form field has no label, so screen readers announce an empty box and autofill guesses.

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

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

Your title is 80 characters, so Google will cut it off around 60: “Rapidly Develop Cloud Apps Based on .NET Core with PowerBuilder | Appeon Website”.

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

4 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 94 pages on appeon.com and 16 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.

There is no /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 /events, which answers with an error. Visitors hit a dead end and search engines drop it.

/products/snapobjects, /elevate and /news have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /elevate, whose canonical is /conference/elevate/2026. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/elevate has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 42 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://www.appeon.com/.

5 of 14 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

1 link from your homepage to your own site is broken, for example https://www.appeon.com/events (500).

3 links go through two or more redirects, for example https://www.appeon.com/freetrial?product=pb.

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.

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

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

appeon.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.

appeon.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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 319 words of visible text.

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 Ads, Google Analytics, Google Tag Manager, Hotjar and Microsoft Clarity (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 17 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 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
