stockcenter.com.ar website review

About 1.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 8.4 s faster on a phone.

45 files are served with short cache lifetimes, so returning visitors download them again (777 KiB).

22 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.0 s.

Google Tag Manager costs a phone 1.9 s of main-thread work and 1.7 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Your mobile performance score is 9. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 7.2 s on main-thread work while loading, 4.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Google CDN and Evergage and others), adding 3.3 MB and 3.5 s of main-thread time.

33 images could be 1.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 750 ms faster on a phone.

About 179 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 950 ms faster on a phone.

Google CDN costs a phone 418 ms of main-thread work and 739 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.

20 long tasks block the main thread while loading, the longest for 459 ms. During a long task the page ignores taps.

Facebook costs a phone 375 ms of main-thread work and 344 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.

Evergage costs a phone 378 ms of main-thread work and 74 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.

The page has 2,388 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Polyfills for old browsers add 83 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

12 KiB could be saved by minifying JavaScript.

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

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.

Real visitors wait 4.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

The first text or image appears after 9.1 s on a phone. Good is under 1.8 s.

Your largest element takes 38.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Header Text”.

Visually, the page fills in at 21.5 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 41.0 s. Good is under 3.8 s.

Scripts block taps and scrolling for 2.1 s in total while the page loads. Good is under 200 ms.

The layout shifts by 0.382 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Real visitors wait 479 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

For real visitors the layout shifts by 0.19 (75th percentile). Good is under 0.1.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 378 ms to 502 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 2.5 s to 3.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.9 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.

Your homepage downloads 8.1 MB in 257 requests on a phone: images 3.8 MB (112), scripts 3.6 MB (64) and other files 397 KiB (55). Under 2 MB keeps phones on slow connections fast.

34 images (2.9 MB) 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.

7 images further down the page (270 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 2.31 g of CO₂e: 277.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 12 elements on the page fail this check, rated critical by axe-core.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

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

1 element has a tabindex above 0, which scrambles the keyboard order.

1 tap target is too small or too close together to hit reliably with a finger.

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

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.

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

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

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

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

Elements marked as presentational should be consistently ignored: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h1 → h3 and 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.

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

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

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

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

The homepage links to 290 pages on stockcenter.com.ar and 23 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.

Your homepage links to /on/demandware.store/Sites-StockCenter-Site/default/Cart-MiniCartShow and /categorias/2x1stock, which answer with an error. Visitors hit a dead end and search engines drop them.

/home and /s/StockCenter all use the title “Stock Center | Zapatillas y ropa deportiva con descuento”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

/entregas.html, /terminos-y-condiciones.html and /preguntas-frecuentes.html use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 155 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=97187085&tm=gtm002&Ver=2&mid=564080b8-075a-4c3e-9065-447310fe2319&bo=1&sid=648a9e90d3a211f1bd130349bf2fe86e&vid=648ac960d3a211f18f060feace2f97bc&vids=1&msclkid=N&pi=91.

38 of 116 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

2 links from your homepage to your own site are broken, for example https://www.stockcenter.com.ar/on/demandware.store/Sites-StockCenter-Site/default/Cart-MiniCartShow (500).

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

Opening https://stockcenter.com.ar goes through 2 redirects before the homepage loads.

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.

stockcenter.com.ar 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 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 424 words of visible text.

stockcenter.com.ar has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

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, Hotjar and Meta Pixel and 4 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 38 cookies, 6 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 44 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
