2. Ahrefs: Helps discover related search terms, analyze competitor keywords, and identify content gaps.
3. Google Keyword Planner: Provides keyword ideas and estimated search volume to help prioritize topics.
4. Google Search Console: Shows actual queries bringing visitors to your website, along with impressions, clicks, CTR, and average position.
