To perform audience analysis and find new markets, social listening can be a valuable tool. By monitoring your own brand, competitors, and industry, you can uncover gaps in geographic locations or demographics that are not being served by existing brands. Social media platforms like YouTube and Reddit can also provide insights into emerging trends and interests. Leveraging brand advocates and influencers can help expand your reach into new markets, while analyzing customer demographics and geography can identify opportunities for growth. By staying on top of social listening, you can gain a deeper understanding of your audience's needs and preferences, ultimately informing your marketing strategies to target new and untapped markets.
