Step‑by‑Step Guide to Finding Low‑Competition Keywords

This step-by-step guide will take you through the process of finding low‑competition keywords using Semrush’s powerful tools.

  1. Start with a broad concept. Think about the main product, service, or topic you want to rank for. For example, if you sell ergonomic chairs, your seed could be “ergonomic office chair.”
  2. Enter the seed into Semrush’s Keyword Overview. The dashboard will show you search volume, keyword difficulty, and CPC. Look for a difficulty score below 30% for low‑competition opportunities.
  3. Explore Keyword Magic. Click the “Keyword Magic Tool” and filter results by “Keyword Difficulty” and “Search Volume.” Use the “Include Phrase” filter to keep the seed term in every suggestion.
  4. Identify long‑tail gems. Long‑tail keywords often have lower competition. In this video, we dive deep into how to find the best long‑tail variations that still attract meaningful traffic.
  5. Analyze SERP features. Review the SERP overview for each keyword. If the results show few high‑authority domains, the keyword is likely easier to rank for.
  6. Group related terms. Use the “Keyword Grouping” feature to cluster synonyms and related phrases. This helps you plan content clusters that reinforce topical relevance.
  7. Validate with competitor data. Check the “Domain Overview” of top competitors to see which keywords they rank for and where gaps exist.
  8. Export and prioritize. Download the list as a CSV, then rank keywords by difficulty, volume, and relevance to your business goals.
