vlex.com website review

57 files are served with short cache lifetimes, so returning visitors download them again (1.9 MB).

Your mobile performance score is 73 (desktop: 87). Pages that score under 90 lose visitors before the first paint.

14 images could be 741 KiB 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.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

5 third-party services load with your homepage (Google Tag Manager, Unpkg and strapiapp.com and others), adding 1.7 MB and 250 ms of main-thread time.

About 382 KiB of JavaScript is downloaded but never used on this page.

strapiapp.com costs a phone 0 ms of main-thread work and 1.4 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.

2 long tasks block the main thread while loading, the longest for 172 ms. During a long task the page ignores taps.

About 107 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.

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 6.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Vincent delivers intelligence that understands the law. Tra…”.

Real visitors wait 203 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors wait 981 ms for your server to start answering (75th percentile). Good is under 800 ms.

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

The page becomes fully interactive after 6.5 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 468 ms to 480 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.1 s to 3.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Linked_In_Vincent_by_Clio_Building_Vincent_Studio_A_Behind_t weighs 526 KiB. On a phone connection a single image that size takes seconds.

4 images are downloaded at several times the size a phone draws them, for example Linked_In_Vincent_by_Clio_Building_Vincent_Studio_A_Behind_t at 3,240 px wide, shown at 342 px. Resized copies would save about 916 KiB.

Your homepage downloads 2.5 MB in 71 requests on a phone: images 2.1 MB (48), scripts 264 KiB (6) and fonts 97 KiB (2). Under 2 MB keeps phones on slow connections fast.

10 images (1.3 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.

11 images further down the page (1.2 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 0.70 g of CO₂e: 84.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

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

No XML sitemap at https://vlex.com/sitemap.xml, so Google discovers your pages only by following links.

7 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 63 pages on vlex.com and 6 external pages.

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.

robots.txt blocks GPTBot and Google-Extended, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers, which the crawlers above handle.

We fetched 15 pages linked from your homepage (of 35 found) and read each the way a search engine does.

1 link to other sites is dead, for example https://login.vlex.com/ (404).

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.

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.

vlex.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.

vlex.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 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 911 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 Ads, 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 6 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
