How can I identify my biggest competitors?

How can I identify my biggest competitors is mainly about finding the alternatives most likely to win the same customer decision. A reliable approach is to search target queries, study marketplaces and advertisements, ask customers what they considered, and include substitutes that solve the problem differently. For example, a project-management platform may compete with software, spreadsheets, email workflows, consultants, and internal processes. The main caution is that competitors should not be limited to businesses that look similar to your own. The final output should provide a prioritized competitor list based on customer overlap, visibility, offer similarity, growth, pricing pressure, and buying influence.
