Keyword analysis in Semrush
Overview
Semrush can support keyword research by combining keyword metrics, intent labels, competitor data, SERP features, content gaps, and tracking. Use it to evaluate whether a keyword is relevant, realistic, and valuable.
Semrush data should guide decisions, but final keyword selection still needs SERP review and business judgment.
Key Metrics and Checks
| Area | What To Review | Why It Matters |
|---|---|---|
| Primary keywords | Main terms aligned with your page or business | Defines the target topic. |
| Secondary keywords | Related and long-tail terms | Improves coverage and supports subtopics. |
| Keyword difficulty | Estimated ranking competitiveness | Helps assess whether the opportunity is realistic. |
| Search volume | Estimated monthly search demand | Shows potential reach. |
| Intent | Informational, navigational, commercial, or transactional | Determines content format and CTA. |
| Trend | Seasonality and changing interest | Helps schedule and refresh content. |
| CPC | Paid-search cost per click | Indicates commercial value and advertiser competition. |
| SERP features | Snippets, local packs, images, videos, ads | Shows click opportunity and format expectations. |
| Competitor keywords | Terms competitors rank for | Reveals gaps and proven opportunities. |
| Keyword cannibalization | Multiple pages targeting same intent | Prevents internal ranking conflicts. |
| Position tracking | Ranking movement over time | Measures progress and volatility. |
Practical Workflow

Balance Difficulty and Volume
| Scenario | Recommendation |
|---|---|
| High volume, high difficulty | Use as long-term pillar target or support with clusters first. |
| Medium volume, medium difficulty | Good candidate for focused content. |
| Low volume, low difficulty | Useful for long-tail, early authority, or high-intent pages. |
| Low volume, high CPC | Consider if business value or conversion intent is strong. |
