Step-by-Step Keyword Research Using SEMrush
SEMrush provides one of the most powerful keyword research systems available today. In 2025, its AI-enhanced database and search intent classification make it ideal for bloggers, affiliate marketers, and SEO professionals.
1. Start with Keyword Overview Tool
The Keyword Overview tool is the foundation of keyword research in SEMrush. It gives you a quick snapshot of any keyword’s potential.
- Search volume (global + country-wise)
- Keyword difficulty (KD%)
- Search intent (Informational, Commercial, Transactional, Navigational)
- CPC & competition level
- Trend over last 12 months
According to SEMrush Official Blog, keywords with clear search intent convert better than high-volume generic keywords.
2. Find Low-Competition Keywords (Golden Strategy)
In 2025, ranking is no longer about chasing high-volume keywords. The real SEO win comes from low competition, intent-based keywords.
✅ Ideal keyword metrics for new blogs:
• KD below 30
• Volume 100–2000
• Clear intent
Use filters inside SEMrush to set:
- Keyword Difficulty: 0–30
- Word Count: 3+ (long-tail keywords)
- Intent: Informational or Commercial
3. Use Keyword Magic Tool (Most Powerful Feature)
The Keyword Magic Tool is where SEMrush truly dominates. It allows you to discover thousands of keyword variations from one seed keyword.
- Broad match keywords
- Phrase match keywords
- Exact match keywords
- Question-based keywords
Example:

4. Analyze SERP Results (Very Important)
Before finalizing any keyword, always analyze the SERP (Search Engine Results Page).
Check:
- Domain authority of ranking sites
- Content length of top pages
- Search intent match
- Featured snippets
If top results are dominated by big brands like HubSpot, Ahrefs, or Wikipedia, the keyword may be hard to rank for a new site.
5. Find Keywords Your Competitors Rank For
Competitor keyword research is one of the fastest ways to grow traffic.
Use Domain Overview → Organic Research → Positions in SEMrush.
- Enter competitor domain
- See all ranking keywords
- Filter by KD & volume
- Export best keywords
This strategy is recommended by Backlinko for fast SEO growth.
6. Identify Search Intent Correctly
In 2025, Google ranks pages based on intent match, not just keywords.
Search Intent Types:
• Informational – guides, tutorials
• Commercial – reviews, comparisons
• Transactional – buy, discount
• Navigational – brand searches
SEMrush automatically labels intent, saving hours of manual work.
7. Save & Organize Keywords (SEO Workflow)
Create keyword lists inside SEMrush to organize your SEO strategy.
- Blog post keywords
- Money keywords
- Informational keywords
- Cluster keywords
This helps you plan content calendars and internal linking easily.
