Most important first.
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.
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.
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.
