deecision.com website review

Your mobile performance score is 84. Pages that score under 90 lose visitors before the first paint.

About 108 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 400 ms.

5 files are served with short cache lifetimes, so returning visitors download them again (67 KiB).

Polyfills for old browsers add 35 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

7 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 200 ms faster on a phone.

1 long task block the main thread while loading, the longest for 86 ms. During a long task the page ignores taps.

1 image could be 47 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

1 third-party service load with your homepage (cal.com), adding 26 KiB and 13 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.

Your largest element takes 4.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is element render delay (2.0 s).

Visually, the page fills in at 4.7 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 4.0 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.

1 image (47 KiB) is 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 0.18 g of CO₂e: 21.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Elements with visible text labels do not have matching accessible names. (1 element).

The homepage links to 30 pages on deecision.com and 0 external pages.

/en, /fr and / all use the title “Deecision — Portfolios, markets and decision support”. Search engines can't tell which page to show for a search, so each competes with the others.

/fr and / use the same meta description. A description written for each page earns more clicks.

Your homepage links to 2 pages by a URL that isn't their canonical one, for example /fr, whose canonical is /en. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 12 pages linked from your homepage and read each the way a search engine does.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

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.

Opening https://deecision.com goes through 2 redirects before the homepage loads.

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.

deecision.com is registered until Nov 2026. If it lapses, the site and its email stop working and someone else can buy the name. Renew it, and turn on auto-renew.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 729 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.

Opening the homepage sets 2 cookies, 1 of them by other companies (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 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
