simtrack.com.br website review

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.1 s.

Your mobile performance score is 86 (desktop: 98). Pages that score under 90 lose visitors before the first paint.

About 177 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 720 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 400 ms).

4 images could be 69 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

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

1 third-party service load with your homepage (Google Fonts), adding 37 KiB and 0 ms of main-thread time.

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.

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' largest content (lcp) went from 2.8 s to 4.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Your largest element takes 3.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Com mais de 20 anos de experiência, a SIM Rastreamento é re…”. Most of its time is element render delay (1.8 s).

Visually, the page fills in at 3.7 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' tap response (inp) went from 213 ms to 219 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

2 images (111 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.

1 image further down the page (44 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.24 g of CO₂e: 29.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

All page content should be contained by landmarks: 11 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.

2 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.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

Your title is only 23 characters: “Sim Rastreamento | Home”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your <h1> is empty.

The homepage links to 46 pages on simtrack.com.br and 15 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://simtrack.com.br/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.

https://simtrack.com.br/author/marketing is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://simtrack.com.br/sobre-sim, https://simtrack.com.br/blog, https://simtrack.com.br/para-voce, https://simtrack.com.br/sim-bike, https://simtrack.com.br/moto and https://simtrack.com.br/para-sua-frota and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://simtrack.com.br/sobre-sim, https://simtrack.com.br/blog, https://simtrack.com.br/para-voce, https://simtrack.com.br/sim-bike, https://simtrack.com.br/moto and https://simtrack.com.br/para-sua-frota and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://simtrack.com.br/para-voce, https://simtrack.com.br/sim-bike and https://simtrack.com.br/acessorios took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 17 found) and read each the way a search engine does.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

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 284 words of visible text.

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.
