How to Do Keyword Research with Semrush in 2026: Beginner to Advanced

Rank a blog post in 90 days with zero backlinks. That's what happens when you pick the right keywords from the start. I've done it multiple times using Semrush, and this guide shows you exactly how.

What You Need Before Starting

You need a Semrush account. The free plan gives you 10 searches per day, which is enough to test the process. If you're serious, the Pro plan at $139/month unlocks everything covered here.

You also need a clear niche or topic cluster in mind. Walking in with "I want to rank for marketing stuff" will waste your time. Come with at least one seed keyword, a target audience, and a general idea of what your content should accomplish.

Optional but useful: a content writing tool like Jasper or Writesonic for turning your keyword list into actual articles once you've done the research.

Step-by-Step Keyword Research Walkthrough

Step 1: Enter Your Seed Keyword into Keyword Overview

Log into Semrush and click "Keyword Overview" in the left sidebar. Type your seed keyword into the search bar. Set your target country and hit search.

You'll see volume, keyword difficulty (KD), CPC, and trend data. Don't obsess over volume right now. Focus on KD first, because high-volume keywords with a KD above 70 will bury you if your site is new.

Step 2: Run the Keyword Magic Tool

Click "Keyword Magic Tool" in the sidebar. Enter the same seed keyword. This is where the real list starts building.

You'll get thousands of related keywords grouped by topic clusters on the left side. Use these clusters to filter down fast. Click on a subtopic that matches your content angle and your list shrinks from 10,000 to something manageable.

Step 3: Filter by Keyword Difficulty and Volume

Set KD to a max of 49 if your domain authority is below 30. Set volume minimum to 100. This removes both impossible keywords and keywords nobody searches.

I personally use KD under 35 for new sites and bump it up once the domain has some traction. The sweet spot for most beginner blogs is 300 to 2,000 monthly searches with KD under 40.

Step 4: Sort by Search Intent

Click the "Intent" column header to sort keywords by intent type: informational, navigational, commercial, or transactional. Match the intent to your content type.

Writing a blog post? Go informational. Building a product comparison page? Go commercial or transactional. Mixing these up is the number one reason pages don't convert even when they rank.

Step 5: Check the SERP for Your Top Keywords

Click the SERP icon next to any keyword to see who's currently ranking. Look at the domain authority of the top 10 results. If you see sites like Forbes, HubSpot, and Healthline dominating page one, skip it for now.

You're looking for SERPs with smaller sites ranking in positions 1 through 5. That's your signal that the keyword is actually winnable.

Step 6: Analyze Competitor Keywords

Go to "Organic Research" and enter a competitor's domain. Click the "Positions" tab. You'll see every keyword they rank for along with their position, traffic, and KD.

Sort by KD ascending and look for low-difficulty keywords your competitor is ranking for that you haven't touched yet. This is the fastest way to find gaps in your content plan.

Step 7: Export and Organize Your Final List

Hit the export button and download your filtered keyword list as a CSV. Open it in Google Sheets. Create columns for: keyword, volume, KD, intent, content type, and status.

Group keywords into topic clusters so related terms support the same page or series of posts. This is how you build topical authority instead of one-off blog posts that never gain momentum.

Step 8: Prioritize and Map Keywords to Content

Pick 5 to 10 target keywords to start. Assign one primary keyword per page and two to four supporting keywords. Don't try to rank one page for 20 unrelated terms.

Once your list is mapped, use a tool like Surfer SEO to optimize your content against what's already ranking. Pair it with Copy.ai or Writesonic to produce drafts faster without losing quality.

Common Mistakes to Avoid

Chasing volume over opportunity. A keyword with 50,000 monthly searches means nothing if you're competing against websites with 10 years of authority. A keyword with 400 searches and a KD of 22 can bring consistent traffic within weeks.

Ignoring search intent. If you write an informational post targeting a transactional keyword, Google won't rank it because it doesn't match what the searcher actually wants. Always check the SERP before committing to a keyword.

Targeting one keyword per article. Successful pages rank for dozens of related terms, not just one. Use Semrush's related keywords and questions tabs to layer in secondary keywords naturally throughout your content.

Skipping competitor research. Most beginners only use the Keyword Magic Tool. The Organic Research section is where the real shortcuts live. Your competitors have already validated which keywords drive traffic.

Never revisiting your keyword list. Search trends shift, especially in 2026. A keyword that was dead two years ago might be exploding now. Check your list every quarter and update your content strategy to match.

Pro Tips

Use the Keyword Gap tool religiously. Enter your domain alongside two or three competitors and filter for keywords they all rank for that you don't. These are proven, traffic-driving keywords that you're simply missing. This one feature alone has shaped my entire content calendar.

Filter by questions. In the Keyword Magic Tool, click the "Questions" tab. Question-based keywords convert well for featured snippets and show up in the People Also Ask section. They're often lower competition and easier to structure content around.

Combine Semrush with Surfer for on-page optimization. Surfer SEO tells you exactly how to structure your content after Semrush tells you what to write about. Using both together shortens the time between publishing and ranking.

Look at keyword trends before committing. The trend graph in Keyword Overview shows whether search volume is growing, stable, or declining. Never build a content strategy around a keyword that's been dropping for 12 months straight.

Track your target keywords from day one. Add your final keyword list to Semrush's Position Tracking tool. You need to see movement to know whether your content is working or needs to be updated.

Use Jasper to speed up content production once your keyword map is ready. The research phase is the bottleneck for most people, but once you have a clear map, AI writing tools can cut production time by 60 percent or more. The keyword research you did in Semrush becomes the brief.

Bottom Line

Keyword research with Semrush is not complicated once you stop treating it like a one-time task and start treating it like an ongoing system. The tools are all there: Keyword Magic, Keyword Gap, Organic Research, Position Tracking. Most people just use one feature and wonder why results are slow.

Start with a seed keyword, filter aggressively for difficulty and intent, steal ideas from competitors, and map everything to a content plan before you write a single word. That order matters.

If you don't have a Semrush account yet, the free trial is enough to run through this entire process and build your first keyword list. Do the research first. Everything else follows from that.
