Why can't search engines access my robots.txt file?

Your robots.txt file returns a 404 error, meaning it's missing or inaccessible. Search engines rely on this file to understand crawling permissions. Create a robots.txt file in your root directory to fix this critical issue.

What does it mean when my site has no date signals?

Your pages lack publication or modification dates that search engines can detect. This hurts freshness scoring and credibility. Add structured data timestamps or visible publication dates to help search engines understand content recency.

Do I need an llms.txt file for my AI robot website?

Your llms.txt file is missing, which could limit AI training data usage permissions. For an AI robotics site like yours, this file helps specify how AI models can use your content. Consider adding one.

How do missing publication dates hurt my site's ranking?

Without date signals, search engines can't assess your content's freshness or authority over time. This particularly impacts E-E-A-T scoring for technical topics. Add clear publication dates and structured data to improve credibility.

Should I add FAQ schema markup to my pages?

Your site currently has no FAQ schema markup, missing opportunities for rich snippets in search results. Adding FAQPage structured data helps your content appear in featured snippets and improves visibility for question-based queries.
