Effective keyword research requires the right tools to uncover search volumes, competition levels, and related terms that your potential patients actually use.
Google Keyword Planner
Google Keyword Planner remains the gold standard for keyword research because it provides data directly from Google’s search database. This free tool shows search volumes, competition levels, and suggested bid ranges for paid advertising.
To access Keyword Planner, you need a Google Ads account, but you don’t need to run active campaigns. Start by entering broad terms like “physical therapy” or “back pain treatment” to discover related keywords and their monthly search volumes.
Pay attention to the competition level indicators. High competition doesn’t necessarily mean SEO difficulty—it refers to paid advertising competition. However, highly competitive keywords often indicate valuable, high-converting terms.
Ahrefs Keyword Explorer
Ahrefs provides comprehensive keyword data including search volume, keyword difficulty scores, and SERP analysis. The tool’s keyword difficulty metric specifically measures SEO competition, helping you identify terms you can realistically rank for.
Use Ahrefs to analyze competitor keywords by entering their domains. This reveals which terms drive traffic to competing practices and identifies gaps in your own keyword strategy.
The “Questions” filter in Ahrefs helps you discover long-tail keywords phrased as questions. These often align with voice search queries and provide excellent content opportunities.
SEMrush Magic Keyword Tool
SEMrush excels at competitive analysis and local keyword research. The Magic Keyword tool generates thousands of related terms and provides detailed competition analysis.
Use the “Questions” and “Related” tabs to find long-tail variations of your primary keywords. These longer phrases often have lower competition and higher conversion rates.
SEMrush’s Position Tracking tool monitors your rankings for target keywords over time, helping you measure the effectiveness of your optimization efforts.
