π Just discovered something new about SEO & AI!
We all know tags help describe a single page, but hereβs the twist:
π Sitemaps (sitemap.xml) tell Google & AI about your entire website and when each page was last updated.
Without it, crawlers guess your structure. With it, you hand them a clean map + freshness signals π .
Example (inside sitemap.xml):
<url>
<loc>https://example.com/ai-seo</loc>
<lastmod>2025-08-24</lastmod>
</url>
= your page URL
= when the page was last updated
This helps search engines & AI summaries pick the freshest content, not outdated info.
π‘ In React apps β put sitemap.xml in /public/ folder.
π‘ In Next.js (App Router) β create app/sitemap.ts and let Next auto-generate lastmod.
π Takeaway:
SEO is shifting from just meta tags β to structured data + sitemaps + freshness.
If you want your content to show up in AI summaries, freshness is no longer optional π.
