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

Your site lacks date signals that search engines use to determine content freshness. Adding publication dates, last modified timestamps, and structured data helps search engines understand how current your content is, which affects rankings for time-sensitive queries.

What is llms.txt and why does my site need one?

Your site returns a 404 error for llms.txt, a file that helps AI systems understand your content preferences. Creating this file allows you to specify how AI models should interact with your content and can improve your site's visibility in AI-powered search results.

How does missing opening content affect my search rankings?

Your pages lack clear opening content that directly answers user queries. Search engines look for immediate, relevant answers at the top of pages to feature in direct answer boxes and improve rankings for question-based searches.

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

Your robots.txt file returns a 404 error, preventing search engines from understanding your crawling preferences. This technical issue can lead to indexing problems and missed opportunities to guide search bots to your most important content.

How do date signals impact my site's search performance?

Your content lacks visible date information that search engines use for freshness scoring. Without publication or update dates, search engines can't determine content recency, potentially lowering your rankings for queries where timeliness matters.
