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.
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.
Sitemap available
AI Readiness
Quick
We found no sitemap for your site.
Why it matters: A sitemap lists every page you want found, so search engines and AI assistants do not miss the ones buried deep in your site.
How to fix it: Most website builders create a sitemap automatically; turn it on and list it in your robots.txt.
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.
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.
