symmetrical.ai website review

About 205 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.0 s faster on a phone.

13 images could be 3.3 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Your mobile performance score is 65 (desktop: 87). Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 283 ms of main-thread work and 279 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.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

3 third-party services load with your homepage (Google Tag Manager, Cookiebot and Google Analytics), adding 433 KiB and 373 ms of main-thread time.

2 files are served with short cache lifetimes, so returning visitors download them again (34 KiB).

Polyfills for old browsers add 14 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

7 long tasks block the main thread while loading, the longest for 156 ms. During a long task the page ignores taps.

About 14 KiB of CSS is downloaded but never applied on this page.

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 13.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Wykorzystujemy pliki cookie do spersonalizowania treści i r…”.

The page becomes fully interactive after 13.9 s. Good is under 3.8 s.

Visually, the page fills in at 7.0 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.2 s on a phone. 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 131 ms to 116 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.7 MB in 54 requests on a phone: images 5.0 MB (23), scripts 597 KiB (13) and fonts 114 KiB (12). Under 2 MB keeps phones on slow connections fast.

woman-hero-src.png weighs 1.8 MB. On a phone connection a single image that size takes seconds.

7 images are downloaded at several times the size a phone draws them, for example woman-hero-src.png at 1,240 px wide, shown at 358 px. Resized copies would save about 1.5 MB.

13 images (4.9 MB) 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.

12 images further down the page (2.9 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.63 g of CO₂e: 195.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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: 70 elements on the page fail this check, rated moderate by axe-core.

<td> elements in a large <table> do not have table headers. (1 element).

Structured data found (FAQPage, Organization and WebSite) but with 1 problem, for example “Organization: sameAs is an empty list”.

The homepage links to 58 pages on symmetrical.ai and 0 external pages.

There is no https://www.symmetrical.ai/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://www.symmetrical.ai/pl/logowanie is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

We fetched 15 pages linked from your homepage and read each the way a search engine does.

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

Social proof on the homepage: 4 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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 1,694 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
