pcm.com.mx website review

About 485 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.6 s faster on a phone.

32 files are served with short cache lifetimes, so returning visitors download them again (394 KiB).

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

Your mobile performance score is 55 (desktop: 82). Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Hubspot and jQuery CDN and others), adding 1.2 MB and 779 ms of main-thread time.

Google Tag Manager costs a phone 497 ms of main-thread work and 781 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 38 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 180 ms faster on a phone.

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

9 long tasks block the main thread while loading, the longest for 158 ms. During a long task the page ignores taps.

39 KiB could be saved by minifying JavaScript.

3 images could be 33 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Desktop scores 82 but mobile only 55. A gap that wide usually means heavy scripts and images that hit phones hardest.

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.

Your largest element takes 15.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Fabricación de cajas a la medida”.

The page becomes fully interactive after 15.2 s. Good is under 3.8 s.

Visually, the page fills in at 6.8 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.4 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 335 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 96 ms to 87 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.1 MB in 83 requests on a phone: scripts 1.3 MB (24), images 461 KiB (28) and other files 179 KiB (24). Under 2 MB keeps phones on slow connections fast.

fabrica-de-papel.jpg 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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.59 g of CO₂e: 70.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

Links must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 5 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.

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

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

Headings skip levels (h1 → h3, h2 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

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

Your meta description is 194 characters; Google truncates after about 160, so the end of your pitch is cut.

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

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

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

The homepage links to 64 pages on pcm.com.mx and 5 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 https://www.pcm.com.mx/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.

/ and https://www.pcm.com.mx/en all use the title “PCM - Papeles y Conversiones de México”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.pcm.com.mx/eventos has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 22 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Cannot read properties of undefined (reading 'classList')”.

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

Large scripts ship without source maps.

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 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 471 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and LinkedIn Insight (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 9 cookies (measured from a US location before any click).

Loading the homepage contacts 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
