silfex.com website review

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

4 images could be 3.5 MB 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.

Your mobile performance score is 66. Pages that score under 90 lose visitors before the first paint.

About 160 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

About 119 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

3 third-party services load with your homepage (Google Tag Manager, Google Fonts and Google Analytics), adding 391 KiB and 213 ms of main-thread time.

14 KiB could be saved by minifying JavaScript.

12 KiB could be saved by minifying CSS.

3 long tasks block the main thread while loading, the longest for 110 ms. During a long task the page ignores taps.

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

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

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.

Your largest element takes 15.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Silfex Home page”.

The page becomes fully interactive after 16.5 s. Good is under 3.8 s.

Real visitors wait 1.1 s 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.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 1.4 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.9 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

3 images weigh 3.5 MB together. On a phone connection a single image that size takes seconds.

Your homepage downloads 4.3 MB in 40 requests on a phone: images 3.6 MB (6), scripts 422 KiB (18) and fonts 175 KiB (7). Under 2 MB keeps phones on slow connections fast.

3 images are downloaded at several times the size a phone draws them, for example 2023_02_1DSC09990_1_Fix-Circle-White.png at 1,000 px wide, shown at 224 px. Resized copies would save about 1.9 MB.

3 images (3.5 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.

1 image further down the page (1.1 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 1.22 g of CO₂e: 146.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 2 elements on the page fail this check, rated critical by axe-core.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

Banner landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 13 characters: “Home - Silfex”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is 184 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 41 pages on silfex.com and 8 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://www.silfex.com/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.silfex.com/contact and https://www.silfex.com/privacy-policy have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.silfex.com/contact has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 17 found) and read each the way a search engine does.

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

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

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

The homepage has only about 158 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (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 4 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
