smileup.pt website review

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

About 127 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

5 images could be 253 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

9 files are served with short cache lifetimes, so returning visitors download them again (96 KiB).

3 third-party services load with your homepage (Cloudflare CDN, Google Fonts and cookiefirst.com), adding 364 KiB and 6 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.

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

1 image further down the page (28 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 0.41 g of CO₂e: 49.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 7 elements on the page fail this check, rated critical by axe-core.

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

Links must have discernible text: 4 elements on the page fail this check, rated serious by axe-core.

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

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

Heading levels should only increase by one: 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.

Elements with visible text labels do not have matching accessible names. (1 element).

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

Your title is only 29 characters: “Clínicas Dentárias - Smile.up”. 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.

Your meta description is only 27 characters: “Clínicas Dentárias Smile.up”. 70 to 160 characters is enough to sell the click.

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.

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

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

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

A phone browser shows 414 words, but the HTML your server sends has only 0. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes 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.smileup.pt/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.

7 of 11 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 “The source list for Content Security Policy directive 'script-src' contains a source with an invalid path: 'https://www.smileup.pt/ads/ga-aud…”.

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

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.

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.

The homepage carries about 414 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and LinkedIn Insight and 2 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 3 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 14 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
