Website Aggregator Launch Plan

I’m preparing to roll out a brand-new aggregator focused exclusively on e-commerce sites and need a clear, actionable launch plan to guide the whole effort from concept to first users.

Scope
• Map the end-to-end go-to-market strategy: positioning, target segments, and a phased roll-out schedule.
• Outline the technical roadmap for ingesting data from leading e-commerce sites, delivering a price-comparison feature that updates in real time.
• Recommend the data-collection methods (public APIs, web scraping best practices, or third-party feeds) and detail any compliance or anti-blocking tactics I should factor in.
• Define key milestones, success metrics, and resource estimates—people, tools, and rough timelines—so I can budget and staff confidently.
• Suggest low-friction marketing channels for launch day (SEO quick wins, email waitlists, partnerships) and a 90-day growth playbook.

Deliverables
1. A concise strategic document (≈10–12 pages) covering the points above.
2. A visual timeline or Gantt chart that ties the technical build, marketing push, and KPI checkpoints together.
3. A one-page risk log with mitigation steps for data accuracy, rate-limit issues, and compliance concerns.

I’m looking for clear reasoning, practical action items, and references to proven tools or frameworks you’ve used on similar projects. If you have experience launching price-comparison platforms or other data-heavy products, please highlight it in your proposal.
