aerosolms.com website review

About 821 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.9 s faster on a phone.

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

23 files are served with short cache lifetimes, so returning visitors download them again (220 KiB).

8 third-party services load with your homepage (POWr, Google Tag Manager and Clarity and others), adding 2.6 MB and 1.3 s of main-thread time.

Your mobile performance score is 57. Pages that score under 90 lose visitors before the first paint.

About 121 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Google Tag Manager costs a phone 373 ms of main-thread work and 848 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.

POWr costs a phone 427 ms of main-thread work and 13 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.

A phone's processor spends 3.9 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

13 images could be 352 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

The page has 1,917 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Shopify costs a phone 64 ms of main-thread work and 1.2 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.

Polyfills for old browsers add 41 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 250 ms faster on a phone.

10 long tasks block the main thread while loading, the longest for 174 ms. During a long task the page ignores taps.

20 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.

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 JavaScript.

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 21.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “BN-01-MOBILE-ADI”.

The page becomes fully interactive after 22.4 s. Good is under 3.8 s.

Visually, the page fills in at 9.9 s (Speed Index). Good is under 3.4 s.

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 270 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 107 ms to 102 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.9 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.0 MB in 400 requests on a phone: scripts 2.2 MB (112), images 1.2 MB (36) and other files 1.1 MB (225). Under 2 MB keeps phones on slow connections fast.

BN-02-MOBILE-ADI.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

2 images are downloaded at several times the size a phone draws them, for example Banner_RSMD_01_RPV.jpg at 600 px wide, shown at 149 px. Resized copies would save about 56 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.42 g of CO₂e: 170.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

3 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.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

8 form fields have no label, so screen readers announce an empty box and autofill guesses.

5 visible links have no text or label, so screen readers cannot say where they go.

Headings should not be empty: 11 elements on the page fail this check, rated minor by axe-core.

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

Your title is 67 characters, so Google will cut it off around 60: “Aerosol Medical Systems | Expertos en Terapia Respiratoria | México”.

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

3 links have no real href, so search engines can't follow them.

The homepage links to 165 pages on aerosolms.com and 10 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.

A description written for each page earns more clicks.

Your homepage links to 12 pages by a URL that isn't their canonical one, for example https://aerosolms.com/collections/terapia-respiratoria/C%C3%A1maras-Espaciadoras, whose canonical is https://aerosolms.com/collections/terapia-respiratoria/c%c3%a1maras-espaciadoras. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 100 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=343118727&tm=shpfy_ui&Ver=2&mid=def43ba1-16f1-4fcd-b004-db638653b586&bo=1&sid=80430090dccf11f1815f15ed065c36f8&vid=80433680dccf11f196be8127c9deff75&vids=1&msclkid=N&pi.

3 errors were logged to the browser console while the page loaded, for example “Error: <symbol> attribute viewBox: Unexpected end of attribute. Expected number, "".”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 477 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and LinkedIn Insight and 5 mores (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 23 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 56 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
