Fix these first
The problems that cost you the most visibility, worst first. Each one says why it matters and how to fix it.
1. Your home page does not load for search engines
It answered nothing. Nothing else matters until it answers 200.
Fix: Check the site is online and not blocking unknown visitors (some firewalls block crawlers).
2. No sitemap found
A sitemap is how you hand Google and Bing the list of pages you want found.
Fix: Most site builders make one for you; turn it on and add a Sitemap: line to robots.txt.
3. No llms.txt file
An optional file that gives AI tools a plain summary of your site. Google says it does not affect search; coding assistants and agents do read it. Nice to have, not a ranking factor.
Fix: Add /llms.txt with one paragraph about you and links to your key pages.
Who is allowed to read your site
Read from your robots.txt. Blocked means that search engine or AI cannot read your pages, so it cannot show or cite them.
