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

Your site lacks date signals that help search engines understand content freshness. Adding publication and update dates to your pages improves search visibility and user trust by showing when information was created or last revised.

What happens when my robots.txt file returns a 404 error?

Your robots.txt file is inaccessible, returning a 404 error. This prevents search engines from understanding your crawling preferences. Create and upload a properly formatted robots.txt file to your site's root directory.

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

Your site is missing an llms.txt file, which helps AI systems understand how to interact with your content. While not required, this file can improve how AI tools process and reference your website's information.

How do missing date signals affect my search engine rankings?

Missing date signals hurt your content's perceived freshness and authority. Search engines can't determine if your information is current or outdated. Adding clear publication and modification dates helps establish content credibility and relevance.

Why should my page opening be longer than 16 words?

Your page openings are too brief at only 16 words. Search engines need substantial introductory content to understand your page topic and context. Expand openings to 50-100 words for better search visibility.
