Why doesn't my site show publication dates to search engines?

Your site has no visible date signals like publication dates or last modified timestamps. Search engines use these dates to understand content freshness and relevance. Add date markup or visible dates to help search engines properly index your content timeline.

What happens when my robots.txt file returns a 404 error?

Your robots.txt file is completely inaccessible, returning a 404 error. This means search engines can't read your crawling instructions and may treat your site unpredictably. Create and upload a proper robots.txt file to your domain root.

Do I need an llms.txt file for AI crawlers?

Your site lacks an llms.txt file, which AI systems use to understand crawling permissions. While not required yet, this file helps control how AI models access your content. Consider adding one as AI crawling becomes more common.

How do missing dates hurt my content's search performance?

Your content shows no freshness signals, making it harder for search engines to assess relevance and authority. Fresh content often ranks better for timely topics. Add publication dates, update timestamps, or structured data to signal content freshness.

Should I add FAQ schema markup to my pages?

Your site has no FAQ schema markup, missing opportunities for rich search results. FAQ schema can make your content appear in featured snippets and answer boxes. Add FAQPage structured data to relevant pages with question-answer content.
