Keyword stemming is a key SEO technique that simplifies words to their basic forms, helping search engines understand and index content better. For example, “run” covers “running,” “ran,” and “runner.” Using stemmed keywords can boost your site’s visibility in search results by capturing more related searches. Just remember to include these keywords naturally in high-quality content that matches what users are looking for. Tools like Google Keyword Planner or SEMrush can help you find the right terms for your niche.
