ack.es website review

About 1.9 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 8.3 s faster on a phone.

86 files are served with short cache lifetimes, so returning visitors download them again (2.2 MB).

5 images could be 836 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 4.8 s faster on a phone.

27 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.4 s.

Google CDN costs a phone 1.7 s of main-thread work and 2.1 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

A phone's processor spends 11.4 s on main-thread work while loading, 7.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 33 (desktop: 41). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google CDN, protechts.net and LinkedIn Ads and others), adding 4.5 MB and 4.3 s of main-thread time.

protechts.net costs a phone 992 ms of main-thread work and 211 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.

LinkedIn Ads costs a phone 688 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.

px-cloud.net costs a phone 456 ms of main-thread work and 325 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.

About 79 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 310 ms faster on a phone.

20 long tasks block the main thread while loading, the longest for 335 ms. During a long task the page ignores taps.

Polyfills for old browsers add 9 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.

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

3 KiB could be saved by minifying CSS.

3 KiB could be saved by minifying JavaScript.

Your largest element takes 23.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “SOFTWARE DE GESTIÓN DMS PARA EL TALLER Y CONCESIONARIO DE A…”.

Visually, the page fills in at 23.0 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 32.8 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.8 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.0 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.

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.

Your homepage downloads 7.0 MB in 179 requests on a phone: scripts 3.8 MB (59), images 1.6 MB (21) and other files 1.1 MB (56). Under 2 MB keeps phones on slow connections fast.

3 images further down the page (342 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

2 images (314 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 2.00 g of CO₂e: 239.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

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.

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

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

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

Headings skip levels (h2 → h6), which makes the page harder to scan with a screen reader.

There are 6 <h1> headlines (“ACK”, “Software de Gestión DMS para el Taller y Concesio…” and “”). One clear main headline is easier for people and search engines.

The homepage links to 30 pages on ack.es and 7 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.

/politica-de-privacidad-y-cookies, /soporte and /aviso-legal have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage and read each the way a search engine does.

7 of 15 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 (Not Found)”.

The page has no <!DOCTYPE html>, so browsers render it in quirks mode.

1 image is served at too low a resolution for sharp phone screens.

Chrome logged issues while loading the page (“Cookie”).

1 link to other sites is dead, for example http://www.twitter.com/ACKzgz (520).

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.

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.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

1 link go through two or more redirects, for example http://www.ack.es/contacta-con-nosotros.

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.

ack.es 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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 1,157 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 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, 3 of them by other companies (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 22 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
