Documentation for developer-facing products functions as a marketing tool, not just a support resource. Technical buyers self-educate before engaging sales, making docs a primary evaluation surface where trust is built or broken. Key trust factors include accuracy, completeness, honesty about trade-offs, freshness, and navigability. Marketing and documentation teams should collaborate throughout the release cycle to create a seamless content experience—consistent terminology, aligned narratives, and cross-linking. Practical recommendations include shipping docs at launch, investing in UX and SEO for doc sites, and measuring documentation's impact on trial-to-paid conversion. Product-led growth trends make this alignment increasingly critical.
