Step-by-Step Semrush Keyword Research Guide for 2025

Follow this detailed process to leverage Semrush’s tools for effective keyword research. We’ll use the example keyword “content marketing” to illustrate each step.

Step 1: Brainstorm Seed Keywords

Start by identifying broad “seed” keywords relevant to your niche. These are the foundation of your research.

Action: Go to Semrush’s Keyword Overview tool and enter a seed keyword like “content marketing.”
Result: You’ll see metrics like search volume (e.g., 33K monthly searches in the US), keyword difficulty (KD: 45%), and intent (Informational).
Tip: Brainstorm 5–10 related terms (e.g., “content strategy,” “SEO content”) to expand your list.

Step 2: Use Keyword Magic Tool for Keyword Ideas

The Keyword Magic Tool generates thousands of keyword variations from a single seed keyword, grouped by topic and intent.

Action: Enter “content marketing” in the Keyword Magic Tool, add your domain for personalized suggestions, and click “Search.”
Result: Get a list of related keywords (e.g., “content marketing strategy 2025,” “content marketing tools”) with metrics like KD (20–50%), volume, and CPC.
Filters: Use “Broad Match” for general ideas, “Exact Match” for precise targeting, or filter by “Questions” for voice search optimization (e.g., “What is content marketing?”).
Tip: Focus on long-tail keywords (4+ words) with KD below 40% for easier ranking.

Step 3: Analyze Competitor Keywords

Use Semrush’s Keyword Gap tool to uncover keywords your competitors rank for but you don’t.

Action: Enter your domain and up to four competitor URLs in the Keyword Gap tool, then click “Compare.”
Result: See “Missing” keywords (e.g., “content marketing agency” with 5K searches, KD: 30%) that competitors rank for.
Tip: Export these keywords to Keyword Manager for tracking and content planning.

Step 4: Build a Content Strategy with Keyword Strategy Builder

Turn your keyword list into a structured content plan using the Keyword Strategy Builder.

Action: Add selected keywords to Keyword Strategy Builder and click “Create List.”
Result: Get a visual map of pillar pages (e.g., “Ultimate Guide to Content Marketing”) and subpages (e.g., “Content Marketing Tools for 2025”).
Tip: Prioritize keywords with high search volume (1K+) and informational or transactional intent for blog posts or landing pages.

Step 5: Track Performance with Position Tracking

Monitor how your content ranks for target keywords using the Position Tracking tool.

Action: Set up a project in Semrush, add your target keywords, and select your target market (e.g., US).
Result: Track daily ranking changes and see which keywords climb into the top 10.
Tip: Use the “Competitors” tab to monitor rival rankings and adjust your strategy.

Step 6: Optimize with Organic Traffic Insights

Integrate Semrush with Google Analytics to uncover “not provided” keywords and analyze user behavior.

Action: Connect your Google Analytics account to Semrush’s Organic Traffic Insights tool.
Result: Identify high-performing keywords driving traffic and optimize underperforming pages.
Tip: Focus on pages ranking #11–20 and update them with long-tail keywords to push them into the top 10.
