Most important first.
Security headers
Domain & Security
Technical
Your site sends 2 of the 5 security headers we look for; missing: csp, x_frame_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 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.
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.
