Sitemaps tell crawlers what exists. RSS feeds tell them what changed. If you don't have one, your new content waits days -or weeks -to be discovered.

AI engines are biased toward recency. An article with no visible date is an article AI can't trust to be current. Visible Date Signal measures whether your pages show clear publication and update dates that both humans and machines can read.
