aed.com.co website review

24 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

46 files are served with short cache lifetimes, so returning visitors download them again (449 KiB).

Your mobile performance score is 86 (desktop: 90). Pages that score under 90 lose visitors before the first paint.

About 23 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 88 KiB of JavaScript is downloaded but never used on this page.

3 images could be 75 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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 8.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

Your largest element takes 2.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “CONSTRUYENDO SUEÑOS”. Most of its time is element render delay (4.9 s).

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

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 logo_invest_solid.png at 797 px wide, shown at 243 px. Resized copies would save about 12 KiB.

1 image (75 KiB) is 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 (75 KiB) 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 0.13 g of CO₂e: 15.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 7 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.

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

The skip-link target should exist and be focusable: 1 element on the page fails this check, rated moderate by axe-core.

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (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.

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

Your title is only 26 characters: “aed – Empresa Constructora”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

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 56 pages on aed.com.co and 9 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.

/nosotros, /nuestros-diferenciadores, /sostenibilidad-empresarial, /todos-los-proyectos, /proyectos-de-vivienda-en-cartagena and /pagos-en-linea and 7 others have no meta description, so Google writes the search snippet from whatever text it finds.

/nosotros, /nuestros-diferenciadores, /sostenibilidad-empresarial, /todos-los-proyectos, /proyectos-de-vivienda-en-cartagena and /pagos-en-linea and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 13 pages linked from your homepage and read each the way a search engine does.

1 of 5 tappable elements near the top of the page is smaller than 24 px, hard to hit with a thumb.

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

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

The server only offers HTTP/1.1, so browsers open several connections and load files more slowly. Most hosts and CDNs turn on HTTP/2 with a setting.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

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.

X-XSS-Protection is set to “1; 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.

aed.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.

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.

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 484 words of visible text.

aed.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.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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.
