selanusa.com.mx website review

About 602 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.3 s faster on a phone.

14 files are served with short cache lifetimes, so returning visitors download them again (285 KiB).

Your mobile performance score is 48 (desktop: 75). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

21 images could be 687 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

8 third-party services load with your homepage (Bigcommerce, Google Tag Manager and Facebook and others), adding 2.3 MB and 880 ms of main-thread time.

Bigcommerce costs a phone 336 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.

Google Tag Manager costs a phone 322 ms of main-thread work and 549 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 72 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

9 long tasks block the main thread while loading, the longest for 256 ms. During a long task the page ignores taps.

The page has 2,127 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 2.1 s on main-thread work while loading, 858 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

Desktop scores 75 but mobile only 48. 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.

5 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.

For real visitors the layout shifts by 0.36 (75th percentile). Good is under 0.1.

Your largest element takes 13.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “slide-2”.

The page becomes fully interactive after 13.7 s. Good is under 3.8 s.

The first text or image appears after 3.7 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 6.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 550 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 2026-10-17, real Chrome visitors' tap response (inp) went from 152 ms to 146 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.4 MB in 70 requests on a phone: scripts 1.2 MB (20), images 840 KiB (28) and fonts 164 KiB (2). Under 2 MB keeps phones on slow connections fast.

thumbnail-banner-hecho-en-mexico-1-.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).

3 images are downloaded at several times the size a phone draws them, for example SER0000113__05563.1790272953.jpg at 500 px wide, shown at 151 px. Resized copies would save about 35 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.67 g of CO₂e: 80.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Some lists contain elements other than list items, which screen readers announce wrongly.

Some list items are not inside a list.

All page content should be contained by landmarks: 8 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: 1 element on the page fails this check, rated moderate by axe-core.

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h3 → 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 only 54 characters: “Selanusa es la mercería en línea mas grande de México.”. 70 to 160 characters is enough to sell the click.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

Your <h1> is empty.

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

The homepage links to 494 pages on selanusa.com.mx and 17 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.

/hecho-en-mexico and /oricut have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 199 found) and read each the way a search engine does.

26 of 113 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 errors were logged to the browser console while the page loaded, for example “The Content-Security-Policy directive name 'Content-Security-Policy:' contains one or more invalid characters. Only ASC…”.

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

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.

selanusa.com.mx 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.

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 501 words of visible text.

DMARC is set to p=none, so mail pretending to be selanusa.com.mx 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 Ads, 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 14 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 20 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
