circla.co website review

50 files are served with short cache lifetimes, so returning visitors download them again (546 KiB).

17 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.2 s.

3 images could be 1.7 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

7 third-party services load with your homepage (Google CDN, Hubspot and Other Google APIs/SDKs and others), adding 3.0 MB and 767 ms of main-thread time.

About 642 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 380 ms faster on a phone.

Your mobile performance score is 60. Pages that score under 90 lose visitors before the first paint.

Google CDN costs a phone 615 ms of main-thread work and 1.1 MB 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.

A phone's processor spends 2.5 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

hubspotusercontent-eu1.net costs a phone 6 ms of main-thread work and 1.6 MB 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.

10 long tasks block the main thread while loading, the longest for 171 ms. During a long task the page ignores taps.

Polyfills for old browsers add 14 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.

2 KiB could be saved by minifying CSS.

The page becomes fully interactive after 19.2 s. Good is under 3.8 s.

The layout shifts by 0.351 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Visually, the page fills in at 5.5 s (Speed Index). Good is under 3.4 s.

Your largest element takes 3.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Circla est votre partenaire de confiance pour maximiser l'e…”.

Scripts block taps and scrolling for 349 ms in total while the page loads. Good is under 200 ms.

6 images 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 4.1 MB in 83 requests on a phone: images 1.8 MB (21), scripts 1.5 MB (26) and other files 369 KiB (7). Under 2 MB keeps phones on slow connections fast.

ChatGPT Image 1 mai 2025, 10_59_14.png weighs 1.5 MB. On a phone connection a single image that size takes seconds.

1 image is downloaded at several times the size a phone draws it, for example ChatGPT Image 1 mai 2025, 10_59_14.png at 1,024 px wide, shown at 206 px. Resized copies would save about 981 KiB.

1 image (1.5 MB) 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.

1 image further down the page (1.5 MB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.16 g of CO₂e: 139.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 image has no alt text, which hurts accessibility and image search.

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

Elements with visible text labels do not have matching accessible names. (2 elements).

Your title is only 4 characters: “Home”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

1 link has no real href, so search engines can't follow it.

The homepage links to 5 pages on circla.co and 7 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 https://circla.co/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.

https://circla.co/sellsy and https://circla.co/hubspot have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 2 pages linked from your homepage and read each the way a search engine does.

Large scripts ship without source maps.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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

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.

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 544 words of visible text.

Before a visitor clicks anything, the page loads HubSpot (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 13 cookies, 7 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 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
