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

Your site lacks date signals that search engines use to determine content freshness. Adding publication dates, last modified timestamps, or structured data markup helps search engines understand when your content was created or updated, improving your rankings for time-sensitive queries.

What does missing opening content mean for my SEO?

Your pages don't have clear opening content that directly answers user queries. Search engines look for introductory paragraphs that immediately address what users are searching for. Without this, your content is less likely to appear in featured snippets or answer boxes.

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

Your site is missing an llms.txt file, which helps AI systems understand your content policies and preferences. While not required, this file can influence how AI tools like ChatGPT and Claude interact with and reference your content.

How do missing publication dates hurt my search rankings?

Search engines can't determine your content's relevance without date signals. Fresh content often ranks higher for trending topics and news-related searches. Your pages may appear outdated to both search engines and users, reducing click-through rates and overall visibility.

Why should all my images have alt text?

None of your 84 images have alt text, which hurts both SEO and accessibility. Alt text helps search engines understand image content for better rankings and enables screen readers to describe images to visually impaired users, improving your site's usability.
