Check how your page loads on a phone and how its link looks when shared
6 of 16 big Brazilian home pages set no working share picture, so their link shows as text in WhatsApp; Lojas Renner's page also took 20.1 seconds to show on Google's phone test.
Give your AI assistant a page address. You get how long it takes to show on a phone by Google's own test, how its link looks when pasted in WhatsApp, LinkedIn or Facebook, and the problems Google will hit, each with the fix to send to whoever runs your site.
Check our home page, lojasrenner.com.br, and two competitors, stone.com.br and dafiti.com.br: how fast each loads on a phone, how the link looks when shared on WhatsApp and LinkedIn, and what to fix first. (Our recorded run below checked 27 big Brazilian home pages the same way.)
What you get
- How long the page takes to show its main content on a phone, from Google's own test
- Whether the link shows a picture and title when pasted in WhatsApp, LinkedIn or Facebook
- The problems Google will hit (title, description, main heading, picture descriptions, page list) and the fix for each, most serious first
- A plain message when a site blocks the check, so you know to test it from a browser
A real run
Checked Oct 13, 2026, on the home pages of 27 well-known Brazilian brands we picked; Loft rerun 16 minutes later after a fix to how page titles are read; WhatsApp previews drawn the same day from each page's share settings. Speed is one run of Google's phone test per site. Brands are examples; not affiliated. PicPay's address opened its business page and Hotmart's its English page; those are the pages measured. Google's test returned no time for Americanas, Olist and PagBank. 11 of the 27 sites gave no audit: 8 blocked the check (including iFood, Natura and Magazine Luiza), O Boticário and Riachuelo didn't answer within a minute, and Will Bank's address didn't resolve.
6 of the 16 home pages audited set no working share picture, so their link shows as text in WhatsApp: Americanas, Dafiti, KaBuM!, Lojas Renner and Olist set none, and Loft's points to a picture that can't be found. Two more, Amaro and Stone, set only a small logo Facebook won't show.
On Google's phone test (a simulated mid-range phone on a slow connection), 12 of the 13 pages it timed took longer than 2.5 seconds, the mark Google rates good, to show their main content on a phone. BTG Pactual's took 36.0 seconds, Lojas Renner's 20.1, KaBuM!'s 19.5; PicPay's business page came in under, at 2.3.
Other fixes it listed: Loft's page title runs 74 characters where Google shows about 60; Olist leaves 68 of 147 pictures without a description, Nuvemshop 58 of 180.
What you do with it: before a campaign, check the page you'll send people to, add a share picture if it has none, and send its load time to whoever runs your site.

Questions
Where does the data come from?
From the page itself, read at the moment you ask, and from Google's own public speed test (PageSpeed Insights) run on a simulated phone.
What does the speed number mean?
Seconds until the largest piece of content shows on a simulated mid-range phone on a slower connection. Google rates 2.5 seconds or less as good. Real visitors on fast phones may see it sooner; the test is the same for every site, so it's fair for comparing.
What is a share picture?
The picture WhatsApp, LinkedIn, Facebook and Slack show when someone pastes your link. Without one, the link shows as a text-only card.
How accurate is it?
Titles, descriptions and pictures are read the way the page first arrives, before its own code adds anything; pages that build their content with code can show more to visitors. Speed is one run of Google's test and varies between runs (Loft measured 6.2 seconds on Oct 12 and 8.0 on Oct 13), so compare big gaps, not small ones.
What if a site blocks it?
Some big sites turn away automated checks. You get a plain message; test that page in your own browser with Google's PageSpeed Insights.
What does it cost?
Nothing; it is free. New accounts also get $5 to try the paid use cases.
Will the site owner know?
No more than any visitor: it loads the public page once, and Google runs its test the same way.
How often should I run it?
Before each campaign that sends people to a page, and after any redesign.
