4. Develop a Content Strategy
Plan and create high-quality, relevant content tailored to each stage of the customer journey—from awareness to decision.
5. Launch and Promote Campaigns
Use a mix of organic and paid tactics: schedule social posts, run PPC ads, send email newsletters, and optimize your website for conversions.
6. Monitor and Analyze Performance
Track key metrics such as traffic, engagement, conversion rates, and ROI using analytics tools. Use this data to identify what’s working and what needs improvement.
7. Optimize and Iterate
Continuously test, analyze, and refine your campaigns based on performance data and user feedback. Digital marketing is an ongoing process, not a one-time effort.
