Most important first.
Search and AI crawlers allowed
AI Readiness
Quick
Your robots file blocks all crawlers, so search engines and AI assistants are told not to read your site.
Why it matters: A site that blocks every crawler cannot be found in search results or described by an AI assistant.
How to fix it: Edit your robots.txt so it no longer disallows everything; most sites need only a sitemap line.
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.
Homepage description
AI Readiness
Quick
Your homepage has no meta description.
Why it matters: Without one, search engines and AI assistants guess at a summary from whatever text they find first.
How to fix it: Write a one- or two-sentence description of your business and add it as the page's meta description.
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.
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.
