Use keyword research tools like Google Keyword Planner or SEMrush to discover high-volume, relevant keywords. Analyze your competitors to see which keywords they are ranking for and identify gaps you can fill. Focus on long-tail keywords for more specific targeting and less competition. Evaluate keyword difficulty and search volume to choose terms that offer the best balance of opportunity and feasibility. Continuously refine your keyword strategy based on performance data and changing trends.
