Recommended Skills
Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Launch is where solo builders turn a shipped product into something crawlers and searchers can find; audits belong on the SEO shelf even when you revisit quarterly in Grow. The skill is explicitly framed as SEO audit, technical audit, and indexing health—core Launch/seo work—not generic marketing copy.
Where it fits
Audit robots, sitemaps, and canonicals before your Product Hunt launch drives bots to half-indexed URLs.
Find content gaps and intent mismatches after three months of flat organic signups.
Re-run technical checks after a headless CMS migration to confirm crawl paths still work.
How it compares
Structured multi-phase audit workflow, not a one-shot meta-tag generator or paid ads playbook.
