Why isn't my site's llms.txt file accessible to AI crawlers?

Your site returns a 404 error when AI systems look for the llms.txt file. This file helps AI crawlers understand how to interact with your content. You need to create and upload an llms.txt file to your root directory to fix this issue.

What does it mean when robots.txt returns a 404 error?

Your robots.txt file is missing or inaccessible, returning a 404 error. This file tells search engines and AI crawlers which parts of your site they can access. You should create a robots.txt file in your root directory.

How do missing date signals hurt my site's search performance?

Your pages lack publication or update dates, making it hard for search engines to assess content freshness. This impacts rankings for time-sensitive topics. Add visible publication dates and last-modified timestamps to your pages to improve this signal.

Why is content freshness critical for my site's authority?

Search engines can't determine when your content was created or updated because date signals are missing. This hurts your site's expertise and trustworthiness signals. Add clear publication and update dates to demonstrate your content's currency and reliability.

Should I add FAQ schema markup to my site pages?

Your site currently has no FAQ schema markup, which means search engines miss opportunities to show rich snippets. Adding FAQPage structured data helps your content appear in featured snippets and voice search results, improving visibility.
