Why doesn't my site show publication dates on content?

Your site lacks visible date signals like publication or last modified dates. Search engines use these timestamps to understand content freshness and relevance. Adding clear date indicators helps both users and search engines evaluate your content's timeliness and trustworthiness.

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

Your robots.txt file is missing and returns a 404 error. This means search engines can't access crawling instructions for your site. While not always critical, having a proper robots.txt helps control how search bots interact with your pages.

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

Your site is missing an llms.txt file. This emerging standard helps AI language models understand how to interact with your content. While not yet widespread, having this file can improve how AI systems process and reference your site.

How do missing dates affect my site's search rankings?

Your content lacks date signals, which impacts freshness scoring in search results. Search engines prefer recent, updated content for many queries. Without clear publication or modification dates, your pages may be viewed as outdated or less authoritative.

Should I add FAQ schema markup to my pages?

Your site has no FAQ schema markup detected. Adding FAQPage structured data helps search engines understand your Q&A content better. This can lead to rich snippets in search results, potentially increasing click-through rates and visibility.
