masvision.com.ar website review

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

The page has 4,225 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Clarity and others), adding 1.4 MB and 1.1 s of main-thread time.

Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

About 575 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 340 ms faster on a phone.

Google Tag Manager costs a phone 640 ms of main-thread work and 898 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.

13 images could be 560 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

A phone's processor spends 3.6 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

12 long tasks block the main thread while loading, the longest for 227 ms. During a long task the page ignores taps.

About 70 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.

6 files are served with short cache lifetimes, so returning visitors download them again (150 KiB).

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

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need.

12 KiB could be saved by minifying JavaScript.

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.

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 0.76 (75th percentile). Good is under 0.1.

Your largest element takes 9.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 21.9 s. Good is under 3.8 s.

Real visitors wait 245 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Scripts block taps and scrolling for 442 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.4 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 225 ms to 203 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.9 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.7 MB in 263 requests on a phone: images 1.9 MB (66), scripts 1.5 MB (56) and other files 865 KiB (131). Under 2 MB keeps phones on slow connections fast.

2 images (223 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 1.34 g of CO₂e: 161.2 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.

15 images have no alt text, which hurts accessibility and image search.

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Your title is 89 characters, so Google will cut it off around 60: “Los mejores Anteojos, Anteojos de sol y lentes de contacto para vos— Mas Vision Argentina”.

Your meta description is 315 characters; Google truncates after about 160, so the end of your pitch is cut.

No XML sitemap at https://www.masvision.com.ar/sitemap.xml, so Google discovers your pages only by following links.

Open Graph is missing og:title and og:description, so shared links fall back to guesses.

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

The homepage links to 549 pages on masvision.com.ar and 11 external pages.

https://www.masvision.com.ar/pages/seguimiento has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.masvision.com.ar/pages/seguimiento, https://www.masvision.com.ar/pages/sucursales, https://www.masvision.com.ar/pages/agenda-tu-visita and https://www.masvision.com.ar/collections/lentes-de-contacto took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 196 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://apps3.omegatheme.com/cookies-notification/client/save-cookies.php' from origin 'ht…”.

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

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.

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.

The homepage carries about 1,497 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Clarity (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 13 cookies (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 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
