Why can't search engines tell when your content was published?

Your site has no date signals like publication dates or last modified timestamps. Search engines can't determine content freshness, which hurts your rankings for time-sensitive topics. Add clear publication and update dates to your articles.

What is llms.txt and why does your site need one?

Your site returns a 404 error for llms.txt, a file that helps AI systems understand your content better. This missing file means AI chatbots might not properly index or reference your content in responses.

How do heading structure problems affect your site's SEO performance?

Your site has 11 heading level skips, like jumping from H1 to H4. This confuses search engines trying to understand your content hierarchy. Fix by using headings in proper order: H1, then H2, then H3.

Why don't any of your 155 images have alt text?

Zero percent of your images include alt text descriptions. This hurts accessibility for screen readers and prevents search engines from understanding your visual content. Add descriptive alt text to improve both SEO and user experience.

How does missing date information impact your search engine visibility?

Without publication or update dates, search engines can't assess your content's relevance or freshness. This particularly hurts performance for news, trends, and timely topics where recency matters for ranking decisions.
