Why can't AI crawlers find my llms.txt file on my site?

Your site returns a 404 error when AI crawlers look for llms.txt. This file helps AI systems understand how to use your content. Create an llms.txt file in your root directory with clear usage guidelines for AI crawlers.

What happens when my robots.txt file isn't accessible to search engines?

Search engines can't access your robots.txt file, getting a 404 error instead. This prevents proper crawling guidance and may hurt your SEO performance. Upload a valid robots.txt file to your root directory immediately.

How does missing date information affect my website's search rankings?

Your content lacks publication dates, making it impossible for search engines to assess freshness. This hurts rankings for time-sensitive queries. Add visible publication dates and structured date markup to all your content.

Why should I care about content freshness signals on my website?

Content without date signals appears stale to search engines, reducing your authority and rankings. Fresh content builds trust with users and search algorithms. Display clear publication and update dates on all pages.

What's FAQ schema and why doesn't my site have it?

Your site lacks FAQ structured data markup, missing opportunities for rich search results. FAQ schema helps your Q&A content appear as expanded snippets in search results, increasing visibility and click-through rates.
