Why is my robots.txt file showing a 404 error?

Your site doesn't have a robots.txt file accessible at the standard location. This means search engines can't find crawling instructions for your site. You need to create and upload a robots.txt file to your root domain to guide search engine crawlers properly.

What does it mean when my site has no date signals?

Your pages don't display publication or update dates anywhere that search engines can detect. This hurts your content's credibility and search rankings. Add visible dates to your articles and use proper schema markup to show when content was created or modified.

Do I need an llms.txt file for my website?

Your site is missing an llms.txt file, which provides instructions for AI language models. While not required, this file helps control how AI systems interact with your content. Create one to specify crawling preferences for AI training and content generation.

How do missing dates affect my website's search performance?

Search engines can't determine when your content was published or updated without date signals. This impacts your site's trustworthiness and relevance rankings. Fresh content performs better in search results, so adding clear publication dates is essential for visibility.

Why are internal links important for my site's SEO?

Your site has no internal links connecting pages together. This prevents search engines from discovering and indexing all your content effectively. Internal links distribute page authority, improve user navigation, and help search engines understand your site's structure and hierarchy.
