vendasolar.com.br website review

About 1.0 MB of JavaScript is downloaded but never used on this page.

Your mobile performance score is 85. Pages that score under 90 lose visitors before the first paint.

4 third-party services load with your homepage (YouTube, Other Google APIs/SDKs and Google/Doubleclick Ads and others), adding 1.8 MB and 417 ms of main-thread time.

YouTube costs a phone 408 ms of main-thread work and 1.7 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.

A phone's processor spends 2.0 s on main-thread work while loading, 958 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.

8 long tasks block the main thread while loading, the longest for 141 ms. During a long task the page ignores taps.

1 image could be 93 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 64 KiB of CSS is downloaded but never applied on this page.

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

The page becomes fully interactive after 16.4 s. Good is under 3.8 s.

Visually, the page fills in at 9.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 286 ms in total while the page loads. Good is under 200 ms.

1 image 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.

Your homepage downloads 2.6 MB in 25 requests on a phone: scripts 2.2 MB (8), HTML 160 KiB (3) and stylesheets 139 KiB (5). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example hero-mockup-XNzVDAXP.png at 1,920 px wide, shown at 292 px. Resized copies would save about 81 KiB.

1 image (102 KiB) is 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 0.75 g of CO₂e: 90.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 buttons have no accessible name, so screen readers announce just “button”.

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

All page content should be contained by landmarks: 120 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.

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 XML sitemap at https://vendasolar.com.br/sitemap.xml, so Google discovers your pages only by following links.

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

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

A phone browser shows 1,078 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://vendasolar.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.

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.

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 1,078 words of visible text.

Opening the homepage sets 1 cookie (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.
