sertec-ec.com website review

Your mobile performance score is 73. Pages that score under 90 lose visitors before the first paint.

69 files are served with short cache lifetimes, so returning visitors download them again (128 KiB).

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.

2 images could be 43 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 200 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

About 47 KiB of CSS is downloaded but never applied on this page.

1 third-party service load with your homepage (Google Fonts), adding 80 KiB and 1 ms of main-thread time.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Your largest element takes 6.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 6.2 s. Good is under 3.8 s.

Visually, the page fills in at 4.9 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

By the Sustainable Web Design model, a visit to your homepage emits about 0.31 g of CO₂e: 37.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Form elements should have a visible label: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 6 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 viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

Alternative text of images should not be repeated as text: 3 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h5 and h3 → h6), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 15 characters: “sertec-ec.com |”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

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

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

The homepage links to 11 pages on sertec-ec.com and 0 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.

/productos, /services, /about-us, /contact, /product/raloy-diesel-advanced-sae-15w-40-api-cj-4-sm and /product/diferenciales-ep-sae-85w-140-api-gl-5 and 3 others have no meta description, so Google writes the search snippet from whatever text it finds.

/productos, /services, /contact, /product/raloy-diesel-advanced-sae-15w-40-api-cj-4-sm, /product/diferenciales-ep-sae-85w-140-api-gl-5 and /product/conjunto-de-biela and 2 others have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 9 pages linked from your homepage and read each the way a search engine does.

5 of 10 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Function rdt not implemented.”.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

The homepage has only about 112 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Opening the homepage sets 7 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 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
