Frequently asked questions

Why is my site missing important date information for search engines?
Your site lacks date signals that search engines use to determine content freshness. This affects both traditional SEO and AI-powered search results. Add publication dates, last modified dates, or structured data with temporal information to help search engines understand when your content was created or updated.
What is llms.txt and why does my site need one?
llms.txt is a file that helps AI language models understand your site's content and context. Your site returns a 404 error when AI systems look for this file. Create an llms.txt file in your root directory to provide AI crawlers with structured information about your site's purpose and content.
How can I make my content appear fresher to search engines?
Your content lacks freshness signals that search engines rely on for rankings. Add visible publication dates, update timestamps, or use structured data markup like datePublished and dateModified. Regular content updates with clear dating help search engines understand your content's relevance and timeliness.
Why are my page openings too short for search features?
Your page openings contain only 8 words, which is too brief for search engines to extract meaningful direct answers. Expand your introductions to 20-40 words that clearly summarize the main topic. This helps search engines generate better snippets and featured results.
Should I add FAQ schema markup to improve my search visibility?
Your site lacks FAQ schema markup, which helps search engines display rich results with expandable question-answer pairs. Add FAQPage structured data to pages with frequently asked questions. This can increase your visibility in search results and provide more engaging snippets for users.
