gexnova.com.co website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

4 images could be 630 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

31 files are served with short cache lifetimes, so returning visitors download them again (119 KiB).

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

About 69 KiB of JavaScript is downloaded but never used on this page.

About 11 KiB of CSS is downloaded but never applied on this page.

1 third-party service load with your homepage (Google Fonts), adding 67 KiB and 2 ms of main-thread time.

Polyfills for old browsers add 7 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.

Visually, the page fills in at 6.3 s (Speed Index). Good is under 3.4 s.

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.

1 image is downloaded at several times the size a phone draws it, for example GEXNOVA-AVISO1500-2-1.png at 1,500 px wide, shown at 82 px. Resized copies would save about 146 KiB.

3 images (359 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.36 g of CO₂e: 42.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 frame has no title, so screen-reader users cannot tell what it contains.

All page content should be contained by landmarks: 13 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.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

1 visible link has no text or label, so screen readers cannot say where it goes.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 22 characters: “Inicio - Gexnova S.A.S”. Between 30 and 65 characters leaves room to say what you do and for whom.

There are 3 <h1> headlines (“Nuestro equipo”, “Orgullo Tecnologico de Santander – Colombia” and “Contáctenos”). One clear main headline is easier for people and search engines.

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

The homepage links to only 3 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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.

/blog has no meta description, so Google writes the search snippet from whatever text it finds.

/blog took over 3 s to send its HTML from our server.

We fetched 1 page linked from your homepage and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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.

gexnova.com.co 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.

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.

Your homepage shows a map but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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.

The homepage shows no opening hours. If customers visit or call, show when.

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 428 words of visible text.

gexnova.com.co has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

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.

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