Our Chrome extension helps you do both. Use it on your own pages to see what's working and what's not, or use it on competitors to see where you need to improve. Every suggestion is explained clearly and accompanied by a fix.
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.
Not every business has the budget for an agency, but they all deserve a chance to be seen.
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.
Each issue comes with the reason it matters, so every audit teaches you a little more about how search works.

Discovery and crawling, AI accessibility and controls, link health
Whether the whole page loads, or only an empty shell that hides the content.
Rendering
Whether the page's structure and wording make its meaning clear.
Content structure, schema, markup
Whether the page looks right when it's listed, shared or cited.
Presentation, images
Who's behind the page, and why anyone should believe it.
Trust and E-E-A-T
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.
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.
Real Google searches, clicks and ranking for the page, taken from your own Search Console. Google is checking our access first, so this switches on shortly after launch.

Checks your language and country links, and finds any that don't match up.
Checks that your name, address and phone number match up, along with your LocalBusiness structured data and your map details.
