Conducting a competitive gap analysis requires you to define your objectives and criteria, identify your competitors and segments, collect and analyze data, and identify and prioritize gaps. Your objectives should include the key factors or metrics you want to compare and measure, such as conversion rates, customer satisfaction, retention rates, or market share. You can use tools like Google Trends, SimilarWeb, or SEMrush to research your competitors' online presence and traffic. To collect data about your competitors' products, prices, promotions, and customer feedback, you can use surveys, reviews, social media, analytics, or industry reports. Additionally, you can use tools like SWOT analysis, Porter's five forces, or perceptual mapping to visualize and compare your competitive advantages and disadvantages. Finally, you can use gap analysis matrix, value proposition canvas, or blue ocean strategy to identify and prioritize the gaps that you can fill or create with your products, services, or marketing campaigns.
