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.
Email sender record (SPF)
Domain & Security
Moderate
Your domain does not publish an SPF record, so mail servers cannot tell which senders are genuinely yours.
Why it matters: Without it, your own emails are more likely to land in spam, and others find it easier to send mail that claims to come from you.
How to fix it: Add an SPF record in your domain's DNS settings; your email provider publishes the exact line to use.
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.
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.
Language declared
AI Readiness
Technical
Your homepage does not declare its language.
Why it matters: Declaring the language helps screen readers pronounce your content and helps search engines show it to the right people.
How to fix it: Add a lang attribute to the page's html tag, for example en-NZ.
Link preview when shared
AI Readiness
Quick
Your homepage is missing the tags that make a full preview when it is shared.
Why it matters: When someone shares your link, these tags decide the picture, title and description people see in the post.
How to fix it: Add Open Graph tags (title, description and image); most website builders have a social sharing setting for this.
