flexcon.com website review

26 files block the first paint until they finish downloading. Deferring or inlining them could save about 6.3 s.

22 files are served with short cache lifetimes, so returning visitors download them again (604 KiB).

About 464 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.6 s faster on a phone.

About 190 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 57 (desktop: 70). Pages that score under 90 lose visitors before the first paint.

7 third-party services load with your homepage (Bing Ads, Google Tag Manager and termly.io and others), adding 1.1 MB and 310 ms of main-thread time.

Bing Ads costs a phone 111 ms of main-thread work and 417 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.

11 KiB could be saved by minifying CSS.

3 long tasks block the main thread while loading, the longest for 133 ms. During a long task the page ignores taps.

1 image could be 112 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 16 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 50 ms faster on a phone.

10 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 50 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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 14.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Flexcon”.

The first text or image appears after 7.2 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 14.6 s. Good is under 3.8 s.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

Real visitors wait 954 ms for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 87 ms to 105 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.0 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.3 MB in 49 requests on a phone: images 1.1 MB (4), scripts 849 KiB (20) and stylesheets 231 KiB (14). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.66 g of CO₂e: 79.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 buttons have no accessible name, so screen readers announce just “button”.

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

All page content should be contained by landmarks: 25 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

3 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h3 → h6, h4 → h6 and h4 → h6), which makes the page harder to scan with a screen reader.

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

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Your meta description is 183 characters; Google truncates after about 160, so the end of your pitch is cut.

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

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 122 pages on flexcon.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 /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.

We fetched 15 pages linked from your homepage (of 47 found) and read each the way a search engine does.

7 of 20 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 “Error with Permissions-Policy header: Parse of permissions policy failed because of errors reported by structured heade…”.

Chrome logged issues while loading the page (“Content security policy”).

HSTS is set, but max-age is 30 days; one year is the recommended minimum.

X-XSS-Protection is set to “1; mode=block1; 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.

flexcon.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.

flexcon.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.

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 439 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 Tag Manager (measured from a US location before any click). A consent tool (Termly) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 2 cookies (measured from a US location before any click).

Loading the homepage contacts 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
