unicarioca.edu.br website review

23 files are served with short cache lifetimes, so returning visitors download them again (2.2 MB).

About 1.0 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.5 s faster on a phone.

12 images could be 2.0 MB 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.

Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (YouTube, hyperflow.global and Other Google APIs/SDKs and others), adding 3.4 MB and 579 ms of main-thread time.

About 110 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

YouTube costs a phone 342 ms of main-thread work and 986 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.

hyperflow.global costs a phone 229 ms of main-thread work and 1.4 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.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 300 ms.

A phone's processor spends 2.2 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Amazon Web Services costs a phone 0 ms of main-thread work and 817 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.

9 long tasks block the main thread while loading, the longest for 115 ms. During a long task the page ignores taps.

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.

Your largest element takes 19.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Conecta UniCarioca!”.

The page becomes fully interactive after 22.3 s. Good is under 3.8 s.

Visually, the page fills in at 12.2 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.6 s on a phone. Good is under 1.8 s.

Real visitors wait 3.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 307 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.9 s to 3.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.4 MB in 72 requests on a phone: images 2.7 MB (18), scripts 2.0 MB (31) and fonts 341 KiB (4). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.52 g of CO₂e: 182.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

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, so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.unicarioca.edu.br/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at unicarioca.edu.br/robots.txt, the first file search crawlers ask for.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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.unicarioca.edu.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.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

Chrome logged issues while loading the page (“Cookie”).

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 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 0 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

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

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.
