artero.com website review

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.3 s.

About 312 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 36 (desktop: 48). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.7 s on main-thread work while loading, 4.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 1.9 MB of JavaScript is downloaded but never used on this page.

8 third-party services load with your homepage (YouTube, Facebook and Google Analytics and others), adding 2.3 MB and 1.3 s of main-thread time.

YouTube costs a phone 904 ms of main-thread work and 1.9 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.

10 files are served with short cache lifetimes, so returning visitors download them again (269 KiB).

20 long tasks block the main thread while loading, the longest for 259 ms. During a long task the page ignores taps.

202 KiB could be saved by minifying JavaScript.

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

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need.

2 images could be 13 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

7 KiB could be saved by minifying CSS.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

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.

For real visitors the layout shifts by 1.06 (75th percentile). Good is under 0.1.

Visually, the page fills in at 16.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 34.8 s. Good is under 3.8 s.

Your largest element takes 5.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Peluquería Canina”.

Scripts block taps and scrolling for 1.4 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.8 s on a phone. Good is under 1.8 s.

Real visitors wait 3.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 134 ms to 225 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.5 s (75th percentile). Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.8 s to 4.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.6 MB in 353 requests on a phone: scripts 4.2 MB (245), stylesheets 483 KiB (16) and images 470 KiB (46). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.58 g of CO₂e: 189.1 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: 1 element on the page fails this check, rated moderate by axe-core.

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

Elements with visible text labels do not have matching accessible names. (1 element).

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

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

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

1 link has no real href, so search engines can't follow it.

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

The homepage links to 80 pages on artero.com and 0 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.

We fetched 15 pages linked from your homepage (of 60 found) and read each the way a search engine does.

13 of 19 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 “Unexpected identifier 'events'”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

10 images are served at too low a resolution for sharp phone screens.

Large scripts ship without source maps.

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

No Content-Security-Policy header, the main browser-side defence against injected scripts.

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.

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

artero.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.

artero.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.

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

The homepage has only about 115 words of visible text; thin pages give Google and first-time buyers little to go on.

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

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

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

DMARC is set to p=none, so mail pretending to be artero.com is still delivered. Reports are on, so moving to quarantine is the next step.

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, Google Tag Manager and Meta Pixel (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 20 cookies, 1 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 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
