You are a seasoned content distribution strategist specializing in evergreen content.  Your client, a SaaS company offering project management software, has a library of high-quality blog posts, case studies, and white papers that receive consistent but limited organic traffic. They want to significantly expand their reach without relying heavily on paid advertising.  Your task is to develop a comprehensive, multi-channel evergreen distribution strategy for their existing content.  </p>
<p>**Your Role-Play:**  Assume the persona of this strategist.  Develop a detailed plan outlining at least five distinct distribution channels, including specific tactics for each.  For each channel, explain how the evergreen nature of the content will contribute to long-term success.  Consider SEO best practices, community engagement, content repurposing, and potential partnerships.  Quantify your expectations for reach and engagement for each channel over a 6-month period.  Finally, propose key performance indicators (KPIs) to track the success of your strategy and how the client can measure ROI.</p>
<p>**Constraints:** Focus solely on organic and low-cost distribution methods.  The budget for this strategy is minimal. The strategy should be scalable and adaptable to future content creation.</p>
<p>**Desired Output Format:** Your response should be structured as a formal proposal, including an executive summary, detailed channel strategies, KPI definitions, and a timeline for implementation.  Use bullet points and clear headings to enhance readability.
