Technical insight, right where you need it.

Halo analyses and scores your site one page at a time. It runs 99 checks on a page, and you can see them grouped into six plain questions, or switch to the technical categories underneath.

Why we built Halo

Not every business has the budget for an agency, but they all deserve a chance to be seen.

Made for your page

Halo works out what kind of page it's looking at, what industry you're in and how your business makes money, then tailors the audit to match.

You learn as you go

Each issue comes with the reason it matters, so every audit teaches you a little more about how search works.

What Halo checks.

Halo runs 99 checks on a page and groups them into six plain questions.

01

Can it be accessed?

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

Discovery and crawling, AI accessibility and controls, link health

02

Can it be seen?

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

Rendering

03

Can it be understood?

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

Content structure, schema, markup

04

Is it shown well?

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

Presentation, images

05

Can it be trusted?

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

Trust and E-E-A-T

06

Can it be acted on?

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

Agent actionability

Halo reads the page itself (HTML, meta tags, headings, structured data and links), then the files crawlers and AI agents check first: /robots.txt, sitemaps, /llms.txt and /.well-known/ agent files.

What deep audits add.

The standard audit covers the fundamentals. Deep audits add four deeper checks, for when you're competing for something specific. It's all free, you just need to sign in.
