HALO · CHROME EXTENSION

Your pages need to work for AI search, not just Google.

Halo checks both. Run it on your own pages or on a competitor's, and everything it flags comes with a fix.

THE AUDIT

Six questions about your page.

Halo analyses and scores your site one page at a time. It checks six fundamental areas and helps you fix any issues it finds. No jargon, just technical insight right where you need it.

Can it be accessed?

Whether search and AI crawlers are let in, or blocked at the door.

Technical and discovery · AI accessibility and controls · Link health

Can it be seen?

Whether the whole page loads, or only an empty shell that hides the content.

Rendering and crawlability

Can it be understood?

Whether the page's structure and wording make its meaning clear.

Content structure · Schema · Markup

Is it shown well?

Whether the page looks right when it's listed, shared or cited.

Presentation · Images

Can it be trusted?

Who's behind the page, and why anyone should believe it.

Trust and EEAT

Can it be acted on?

Whether an AI assistant could actually use the page to get something done.

HOW IT WORKS

What Halo reads.

Halo reads the page you are on, then asks the site the same questions a crawler would. It then tells you how to fix any issues and why they matter. It can be used on any site to see what's working and what's not, which is especially useful when checking out your competitors.

The page itself

When you run an audit, Halo reads that page's content to work out its verdict.

  • HTML and meta tags
  • Headings
  • Structured data (JSON-LD)
  • Links

What crawlers and agents see

It also requests a few public files on the same site, the ones any browser or crawler can fetch.

  • /robots.txt
  • Sitemaps, such as /sitemap.xml
  • /llms.txt
  • /.well-known/ agent files
OPTIONAL

Connect Search Console.

Sign in with Google and Halo shows your own performance and URL inspection data for the site you are auditing, read only. That data moves between you and Google. It never reaches us, and you can disconnect at any time. The audit works fine without it.

PRIVACY

Nothing leaves your machine.

Halo runs its checks inside your browser. No analytics, no telemetry, no tracking pixels, no cookies, no advertising. We do not measure how you use it.

WHAT IS STORED, AND WHERE

Your page type, industry and model selections, cached audit results, and your Search Console connection state all live in your browser's local storage on your own device. Page facts are cleared when you close the browser. Your Google sign in token is held by Chrome itself, not by Halo.
