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

Your site lacks date signals like publication dates or last-modified timestamps. Search engines can't determine content freshness without these indicators. Add visible publication dates and structured data markup to show when your content was created or updated.

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

Your site returns a 404 error for llms.txt, a file that helps AI systems understand your content structure. This file provides context about your site's purpose and content organization. Create an llms.txt file in your root directory to improve AI discoverability.

How do search engines evaluate my content's freshness without dates?

Search engines can't assess your content's relevance or timeliness without date signals. Fresh content ranks better for time-sensitive queries. Your site needs visible publication dates and proper schema markup to communicate content freshness to search algorithms.

Should I add FAQ schema markup to my website pages?

Your site lacks FAQ schema markup, missing opportunities for rich snippets in search results. FAQ schema helps your Q&A content appear as expandable answers in Google. Add FAQPage structured data to relevant pages containing question-and-answer content.

Why does my site need social proof signals for SEO?

Your site shows no social proof signals like testimonials, reviews, or social media mentions. These signals build trust and authority with both users and search engines. Add customer testimonials, review widgets, or social media integration to demonstrate credibility.
