Most important first.
Always-secure instruction (HSTS)
Domain & Security
Technical
Your site does not tell browsers to always use the secure connection.
Why it matters: Without this instruction, a browser may still try the insecure address first, which leaves room for the connection to be tampered with.
How to fix it: Ask your developer or host to add the Strict-Transport-Security header once HTTPS works on every page.
Security headers
Domain & Security
Technical
Your site sends 0 of the 5 security headers we look for; missing: hsts, csp, x_frame_options, x_content_type_options, referrer_policy.
Why it matters: These headers tell browsers how to protect visitors - for example, stopping your pages being framed inside someone else's site.
How to fix it: Ask your developer or host to add the missing headers in the server or hosting settings.
Email protection policy (DMARC)
Domain & Security
Moderate
Your domain does not publish a DMARC record, which lets anyone send email that claims to come from your domain.
Why it matters: A DMARC policy tells receiving mail servers what to do with mail that fails your checks, which protects your customers and your inbox placement.
How to fix it: Add a DMARC record in your DNS, starting with a monitoring policy, then tighten it once your legitimate mail passes.
AI guide file (llms.txt)
AI Readiness
Quick
Your site does not publish an llms.txt file.
Why it matters: An llms.txt file is a short, plain summary of your business and key pages that AI assistants can read quickly and quote accurately.
How to fix it: Create a text file at /llms.txt with a one-paragraph description of your business and links to your most important pages.
One main heading
AI Readiness
Quick
Your homepage has no main heading, or more than one.
Why it matters: One clear main heading tells readers and machines what the page is about at a glance.
How to fix it: Make sure exactly one heading on the page is marked as the main (H1) heading.
Address findable
AI Readiness
Quick
We found no street address on your homepage.
Why it matters: A visible address tells customers and AI assistants where you are, and matches you to your Google listing.
How to fix it: Add your street address to the homepage, in the same form as on your Google listing.
Contact form findable
AI Readiness
Quick
We found no contact form on your homepage.
Why it matters: A form lets a customer reach you at any hour without picking up the phone.
How to fix it: Add a simple contact form, or a clear link to one, on your homepage.
