Why doesn't your site show when content was published or updated?

Your site lacks date signals like publication dates, last modified timestamps, or structured data markup. Search engines can't determine content freshness without these signals. Add visible dates to articles and implement proper schema markup to improve rankings and user trust.

What is llms.txt and why is it missing from your site?

Your site returns a 404 error when accessing llms.txt. This file helps AI systems understand how to interact with your content. Create an llms.txt file in your root directory to provide guidance for AI crawlers and language models accessing your site.

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

Your robots.txt file returns a 404 error, preventing search engines from understanding crawling instructions. Create a properly formatted robots.txt file in your root directory to guide search engine bots and avoid potential indexing issues.

How do missing date signals affect your search engine rankings?

Search engines prioritize fresh, recently updated content in rankings. Without date signals, your content appears stale regardless of actual freshness. Add publication dates, update timestamps, and schema markup to signal content recency and boost search visibility.

Should your site include FAQ schema markup for better SEO?

Your site lacks FAQ schema markup, missing opportunities for rich snippets in search results. Add FAQPage structured data to eligible content to increase visibility, click-through rates, and help search engines better understand your content's question-answer format.
