Ranked across all five checks. Accessibility and AI search lead, because they carry legal risk and lost visibility.
Your homepage builds its text with JavaScript, so we loaded it in a real browser and checked the page people see. Speed still measures the HTML and files a phone downloads first.
Run the audit again to see your new scores.
Auditvia's checks of your page, weighted like axe-core's rules. Automated tests catch part of WCAG; keyboard and screen-reader testing by a person covers the rest.
The basics search engines check before anything else, from Auditvia's own read of your homepage, robots.txt and sitemap.
What your homepage makes a phone download and run, measured file by file.
Google Lighthouse on a simulated mid-range phone and network. A few points of difference between runs is normal.
Judged from your homepage text by TypeSafe's Jev. It can't see your design, deck or analytics; a person reviews those with you on the call.
Your report, kept as a link. Five scores and the fixes worth doing first, one click away whenever you're ready.
The lines a stranger trips on. The sentences in your message and copy that the report flags, so you can read them the way a buyer would.
Ryan's note, two days later. The first thing he'd look at in your report.
“We hired Alterra to create the launch video for our $10M raise. It generated more than 1.4M views and 40K+ likes across our social channels.”

Overall 64 · Needs work · example: yourcompany.com
A site is a block on a carriage. It slides under five gauges, one for each check, and each needle turns to that score on a 0 to 100 dial. The grey rider stays at each reading, and the switch swaps the labelled example for the real scan of alterra.studio.
The accessibility problems automated checks can catch, like images without descriptions, unlabelled form fields and buttons a screen reader can't name, each with the fix. Contrast is checked in Google's rendered test alongside. No overlay widget.
Whether AI assistants can read and describe you: crawlers allowed, llms.txt, structured data, a clear organization identity and one plain line about what you do.
Indexing rules, titles, descriptions, robots.txt, sitemap, HTTPS, link text and the other basics search engines check before anything else.
What your homepage makes a phone download and run: page weight, JavaScript, other companies' scripts, images, fonts, caching and server response. Google's phone test runs alongside as a cross-check.
Can a stranger tell what you do, who it's for and why you? Each opening sentence is also judged: specific, vague or empty marketing.
Auditvia reads your homepage. It doesn't see your design next to your stage, your deck, your product or your analytics, so those criteria are marked as not measurable instead of guessed. A person from the studio covers them on the call.
Your homepage address and its scores for 24 hours, so a repeat scan is instant. Your IP address only limits scans to five an hour. No email, no account, nothing sold or shared.
How the audit works, what it misses and what we keep.
Yes. No email, no account, no trial. It's how Alterra Studio shows founders what we look for. If you want help with the fixes you can book a call, and nothing changes if you don't.
Alterra Studio, a design and development studio for startups. Auditvia is our audit tool; the same senior team that builds our clients' sites reviews any report you bring to a call.
No. A judgment model (TypeSafe's Jev) answers narrow questions about your page, such as whether a stranger could say what you sell, each with a probability. Ordinary code adds those answers up, so every point traces back to evidence you can read.
No tool can on its own. Automated checks catch part of what WCAG asks for; the rest needs a person testing with a keyboard and a screen reader. Auditvia shows you the automated part with fixes your developers can ship, and we can cover the rest on a call. We don't sell overlay widgets.
Whether assistants like ChatGPT, Claude, Perplexity and Google's AI answers can read your site and describe you correctly. Auditvia checks the parts you control: whether their crawlers are allowed, an llms.txt file, structured data that says who you are, and a plain sentence about what you do.
No. Your accessibility, SEO and speed scores come from Auditvia's own checks of your live homepage: what it makes a phone download and run, which other companies' scripts it loads, and what search engines and screen readers can read. Every check shows its rule and evidence in the report. Google's Lighthouse runs alongside as a cross-check, because it's the number your developer will quote, and it covers what only a rendered page shows, like colour contrast.
They measure different things. Auditvia counts real files and checks rules your page passes or fails, so its scores only move when your site changes. Google's Lighthouse times a simulated phone loading your page, which moves a few points from run to run. Use both: ours says what to fix, Google's shows how it feels on a slow phone.
Anything a homepage can't show: your design next to your stage, your deck, your product, your analytics and how your team ships. Those criteria are marked as not measurable instead of guessed.
Your homepage address and its scores, for 24 hours, so a repeat scan is instant. Your IP address is only used to limit scans to five an hour. Nothing else is kept or sold, unless you ask for the teardown by email: then we also keep your first name and email to send it and a few follow-up notes from Ryan, and every email has an unsubscribe link. Google PageSpeed checks the page, a scoring model reads its text, and pages built with JavaScript are loaded in Cloudflare's browser service.
Yes. Some homepages, often React apps and Web3 or game sites, send almost no text until JavaScript runs. When Auditvia finds fewer than a few lines of text in your HTML, it loads the page in a real browser on Cloudflare and runs the same checks on what that browser shows: accessibility, SEO, AI search and your copy. Speed still measures the HTML and files a phone downloads first. The report says when it did this. If the page still shows almost no text after loading, we tell you instead of guessing.
Free, about a minute, no email. Then decide what to fix, with or without us.
