How does an open launch page help SEO?
Every approved app gets a public, crawlable page with structured data, category links, tool links, and launch archive placement.
Are topic pages just search filters?
No. Topic pages include editorial context, FAQs, and curated internal links so they are useful landing pages rather than thin filtered results.
