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

Your site lacks date signals like publication dates, last modified timestamps, or schema markup. Search engines can't determine content freshness without these indicators. Add visible dates to articles and implement proper date markup to improve crawling and ranking.

What is llms.txt and why is it missing from my website?

Your site returns a 404 error for the llms.txt file. This file helps AI systems understand your content licensing and usage preferences. Create an llms.txt file in your root directory to communicate with AI crawlers and language models.

How do date signals affect my site's search engine performance?

Your content shows no publication or update dates, making it appear stale to search engines. Fresh content signals relevance and authority. Add clear timestamps to pages and use structured data to help search engines understand your content's timeliness.

Why can't visitors find social proof signals on my website?

Your site lacks testimonials, reviews, social media links, or trust badges that build credibility. Social proof helps establish authority and trustworthiness with both users and search engines. Add customer testimonials, review widgets, or social media integration.

What contact information should I display to improve site transparency?

Your site doesn't show clear contact details, physical address, or team information. Contact transparency builds trust and satisfies E-E-A-T guidelines. Add a detailed contact page with multiple contact methods, business address, and team member profiles.
