Keyword research is one of the most important activities in SEO. It helps website owners, bloggers, marketers, and businesses understand what people are searching for on Google and which search terms can bring relevant traffic to their websites.
Semrush is one of the popular SEO platforms that provides a range of keyword research features. With Semrush, you can discover keyword ideas, analyze search volume, understand keyword difficulty, identify search intent, research competitors, and find long-tail keyword opportunities.
In this guide, we will explain how to do keyword research on Semrush, what its important metrics mean, and how beginners can use the platform to build a better SEO keyword strategy.
What Is Semrush?
Semrush is an SEO and digital marketing platform that provides tools for keyword research, competitor analysis, website auditing, backlink analysis, content optimization, and other digital marketing activities.
For keyword research, Semrush can help you discover search terms related to your topic and evaluate their potential before creating content.
For example, if your website focuses on SEO, you can enter a broad keyword such as “keyword research” into Semrush and explore related keywords and variations.
What Is Keyword Research on Semrush?
Keyword research on Semrush is the process of using Semrush’s keyword research features to discover and evaluate keywords that may be relevant to your website.
The platform can provide useful information such as:
- Keyword search volume
- Keyword difficulty
- Search intent

This information can help you decide which keywords are worth targeting in your content.
Why Use Semrush for Keyword Research?
There are many ways to perform keyword research, but Semrush brings several useful SEO data points together in one platform.
1. Discover New Keyword Ideas
You can enter a seed keyword and find related search terms that you may not have considered.
For example, starting with:
keyword research
could lead to ideas such as:
- keyword research tools
- keyword research for SEO
- how to do keyword research
- keyword research strategy
- keyword research for beginners
These variations can become blog topics, guides, FAQs, or supporting sections of larger articles.
2. Analyze Keyword Difficulty
Keyword difficulty can help you estimate how challenging it may be to compete for a particular search term.
A highly competitive keyword may require a stronger website, better content, authoritative backlinks, and a more comprehensive SEO strategy.
For newer websites, identifying relevant keywords with manageable competition can often be a more practical approach.
3. Understand Search Intent
Semrush can help identify the search intent associated with keywords.
Search intent generally falls into categories such as:
- Informational
- Navigational
- Commercial
- Transactional
Understanding intent helps you choose the correct content format for a keyword.
4. Research Competitors
Competitor keyword research can reveal search terms for which competing websites are receiving organic visibility.
This can help you identify content gaps and potential keyword opportunities for your own website.
How to Do Keyword Research on Semrush
The following process provides a practical starting point for beginners.
Step 1: Choose a Seed Keyword
Start with a broad keyword related to your business, service, or content topic.
For example, if you provide SEO services, your seed keywords could include:
- SEO services
- SEO agency
- keyword research
- local SEO
- technical SEO
A seed keyword does not need to be your final target keyword. Its purpose is to generate additional ideas.
Step 2: Enter the Keyword Into Semrush
Use Semrush’s keyword research functionality and enter your seed keyword.
The platform will return keyword data and related opportunities.
Depending on the keyword and available data, you may see information related to search volume, keyword difficulty, intent, trends, and related terms.
Step 3: Check Search Volume
Search volume indicates the estimated number of searches a keyword receives during a given period.
Higher search volume can mean greater traffic potential, but it can also mean greater competition.
Do not select keywords based only on search volume.
A keyword with moderate search volume and highly relevant intent may provide more value than a broad keyword with very high volume.
Step 4: Analyze Keyword Difficulty
Keyword difficulty is another important metric to consider.
If a keyword is extremely competitive, ranking for it may require considerable authority and resources.
For a new website, you can investigate more specific keywords and long-tail variations that may provide realistic opportunities.
Step 5: Check Search Intent
Look at the intent associated with each keyword.
For example:
“What is keyword research?”
has informational intent because the user wants an explanation.
On the other hand:
“keyword research service”
may have commercial or transactional intent because the searcher may be looking for a provider.
Your content should match the intent.
Finding Long-Tail Keywords in Semrush
Long-tail keywords are specific search phrases that usually contain several words.
Examples include:
- How to do keyword research using Semrush
- Best Semrush keyword research strategy for beginners
- How to find low competition keywords in Semrush
- How to use Semrush for SEO keyword research
These keywords can be valuable because they often represent a more specific user need.
Instead of creating content around a broad topic only, you can use long-tail keywords to develop focused articles that answer specific questions.
Using Keyword Variations and Related Keywords
A good article should not depend on one exact keyword.
Semrush can help you identify related phrases and keyword variations that can expand your topic.
For an article about keyword research, related terms could include:
- SEO keyword research
- keyword analysis
- keyword difficulty
- search volume
- long-tail keywords
- keyword strategy
- competitor keyword research
- SEO tools
Use these terms naturally where they add value.
Avoid inserting keywords simply to increase keyword frequency.
Competitor Keyword Research With Semrush
One of the useful applications of Semrush is competitor analysis.
You can research competing websites to understand:
- Which keywords they rank for
- Which pages attract organic traffic
- What topics they cover
- Which keywords may represent content gaps
- How competitive specific search terms are
For example, if a competitor ranks for several useful keywords related to “local SEO,” you can analyze those topics and determine whether your website should create better or more comprehensive content around them.
The goal is not to copy competitors.
Instead, use competitor data to understand the market and identify opportunities to create something more useful.
How to Find Low-Competition Keywords on Semrush
Finding low-competition keywords can be particularly useful for new websites.
A practical process is:
- Enter a broad seed keyword.
- Review related keyword ideas.
- Filter or sort the results based on relevant metrics.
- Look for specific long-tail terms.
- Check search intent.
- Review the current Google search results.
- Select keywords that match your website and content capabilities.
Remember that a low keyword difficulty score does not guarantee rankings.
Google considers many factors, including relevance, content quality, authority, links, website experience, and other signals.
Keyword Research for Content Planning
Semrush keyword research can also be used to build a content calendar.
For example, suppose your main topic is SEO.
You could create a content cluster such as:
Main Topic
SEO Guide
Supporting Topics
- What is SEO?
- Keyword Research Guide
- Keyword Research on Semrush
- On-Page SEO
- Technical SEO
- Local SEO
- Internal Linking
- SEO Content Writing
- Google Search Console Guide
These pages can be connected with relevant internal links.
This approach helps create a more organized website structure and allows you to cover a topic comprehensively.
Common Mistakes When Using Semrush for Keyword Research
Choosing Keywords Only by Search Volume
High-volume keywords are not automatically the best keywords.
Ignoring Search Intent
If your content does not satisfy what the searcher wants, ranking may be difficult even when the keyword looks attractive.
Targeting Extremely Competitive Keywords
New websites may struggle against established websites for highly competitive terms.
Ignoring Long-Tail Keywords
Specific queries can provide valuable content opportunities and may be easier to target.
Copying Competitor Keywords Without Analysis
A keyword that works for one website may not be appropriate for another.
Always consider relevance, intent, competition, and your own website’s authority.
Focusing Too Much on SEO Metrics
SEO tools provide estimates, not guarantees.
Use Semrush data together with actual Google search results and your understanding of your audience.
Semrush Keyword Research vs. Google Keyword Planner
Both Semrush and Google Keyword Planner can be useful for keyword research, but they serve somewhat different purposes.
Semrush provides a broad SEO research environment that includes keyword analysis, competitor research, organic research, backlinks, site auditing, and content-related features.
Google Keyword Planner is primarily designed for keyword planning within Google’s advertising ecosystem and can also provide useful keyword ideas and search-volume-related information.
For an SEO campaign, marketers may use multiple sources rather than relying on one tool alone.
How to Choose the Right Keyword From Semrush
When selecting a keyword, consider these factors together:
Relevance:
Does the keyword directly relate to your topic, product, or service?
Search Intent:
Does the intent match the type of content you want to publish?
Search Demand:
Does the keyword have enough search interest to justify targeting it?
Competition:
Can your website realistically compete for the term?
Business Value:
Could ranking for the keyword attract the right audience?
A keyword that performs well across these areas can be a stronger candidate than one selected purely because it has high search volume.

Final Thoughts
Keyword research on Semrush can help you turn broad SEO ideas into a structured keyword strategy. By analyzing search volume, keyword difficulty, search intent, related terms, and competitor data, you can make more informed decisions about the content you publish.
However, SEO success does not come from choosing keywords alone. The strongest strategy combines keyword research with high-quality content, technical SEO, internal linking, website authority, and a good user experience.
Use Semrush as a research and decision-making tool, but always evaluate keywords from the perspective of your actual audience and the search results.
