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. Search engines can't tell when your pages were created or last modified. Adding publication dates and last-updated timestamps helps search engines understand your content's relevance and can improve your rankings for time-sensitive queries.

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

llms.txt is a file that tells AI systems how to interact with your content. Your site returns a 404 error when AI crawlers look for this file. While not required, having llms.txt can help control how AI models access and use your content, especially as AI-powered search becomes more common.

How can I make my content work better with AI search?

Your pages lack opening content that directly answers user questions. AI systems prefer content that starts with clear, direct answers before providing supporting details. Restructuring your content to lead with key information helps AI understand and potentially feature your content in AI-generated responses.

Why is my robots.txt file returning 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. Without it, crawlers may have difficulty understanding your site's structure and access permissions, potentially affecting how your content is indexed.

Does having outdated content hurt my search engine rankings?

Yes, content without clear freshness signals can hurt your rankings. Search engines favor recent, updated content for many queries. Your site shows no publication or modification dates, making it appear stale. Adding timestamps and regularly updating content signals to search engines that your information is current and reliable.
