sislogica.com.br website review

34 files are served with short cache lifetimes, so returning visitors download them again (1.1 MB).

About 267 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

13 images could be 499 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 900 ms faster on a phone.

Your mobile performance score is 71. Pages that score under 90 lose visitors before the first paint.

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 400 ms.

Google Maps costs a phone 202 ms of main-thread work and 478 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.

About 47 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 250 ms faster on a phone.

3 third-party services load with your homepage (Google Maps, Google Fonts and Other Google APIs/SDKs), adding 624 KiB and 204 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

1 long task block the main thread while loading, the longest for 54 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.

Your largest element takes 10.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “logo”.

The page becomes fully interactive after 10.5 s. Good is under 3.8 s.

Visually, the page fills in at 4.7 s (Speed Index). Good is under 3.4 s.

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

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.

1 image is downloaded at several times the size a phone draws it, for example cainiao.png at 405 px wide, shown at 68 px. Resized copies would save about 46 KiB.

6 images further down the page (333 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

4 images (284 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.47 g of CO₂e: 56.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 frame has no title, so screen-reader users cannot tell what it contains.

Links must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

Contentinfo landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one contentinfo landmark: 1 element on the page fails 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.

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

Headings skip levels (h2 → h4 and h2 → h4), 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 9 characters: “Sislogica”. 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.

There are 2 <h1> headlines (“” and “Desenvolvimento de soluções corporativas sob medi…”). One clear main headline is easier for people and search engines.

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.

No XML sitemap at http://sislogica.com.br/sitemap.xml, so Google discovers your pages only by following links.

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

The homepage links to only 1 page on your own site, so visitors and crawlers find few routes into the rest of it.

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

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://sislogica.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.

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.

Your homepage shows a map but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Social proof on the homepage: 9 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

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 shows no opening hours. If customers visit or call, show when.

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 350 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
