[jamespepper81]

To enhance user engagement, SEO, and content marketing for BitSleuth, we should implement a robust blog and newsletter system integrated with the Next.js 15 site.

Goals:

• Establish BitSleuth as a thought leader on Bitcoin transparency, self-custody, and blockchain analytics.
• Enable delivery of product updates, educational content, and news to our user base.

Blog Functionality

• Create a /blog route with a visually engaging, responsive layout.
• Support for article categories (e.g., Bitcoin Analysis, Self-Custody Tips, Product Updates).
• Integrate a modern, user-friendly CMS (e.g., Sanity, Contentful, or Notion API) for non-technical authors to manage posts.
• Render blog index, featured posts, individual article pages, and author bios.
• Add SEO best practices (Open Graph tags, meta descriptions, structured data) to blog pages.
• Support for code blocks and image embeds in articles.
• Enable social sharing and post comments (consider solutions like Disqus, giscus, or custom with Next.js API routes).

Newsletter Integration

• Add newsletter subscription forms:
  • Standalone form on blog index and article pages
  • Integrated in website footer
• Integrate with a reliable email marketing service (e.g., Mailchimp, ConvertKit, Buttondown, or custom solution)
• Automate welcome email for new subscribers and manage the mailing list securely
• Ensure GDPR compliance and clear opt-in/opt-out processes

Additional Recommendations

• Prepare documentation for content editors on creating and managing blog posts.
• Track newsletter sign-ups and blog engagement (Google Analytics, Plausible, etc.)
• Consider providing newsletter-only exclusive content for incentive.

Acceptance Criteria:

• Blog pages and CMS integration live on production
• Newsletter sign-up, email automation, and list management are operational
• Adequate documentation for editors and compliance checks in place
