SEO involves more than adding keywords to a website. You need to understand what people search for, how competitors perform, which pages rank, and what technical problems may affect your site.
This is where the Semrush SEO tool can help.
So, what is Semrush used for? Semrush is a digital marketing platform for keyword research, competitor research, technical SEO, backlink analysis, rank tracking, content optimization, and AI search visibility.
It brings many useful SEO tools into one platform. This makes it useful for bloggers, agencies, ecommerce stores, SEO professionals, and small businesses.
What Is Semrush?
Semrush is an online marketing platform that helps users study websites, keywords, competitors, content, and search performance.
Its main features include:
- Keyword research
- Competitor analysis
- Site audits
- Rank tracking
- Backlink research
- Content optimization
- Local SEO
- Advertising research
- Market research
- AI search visibility
It can support both SEO and wider online marketing campaigns.
1. Semrush Keyword Research
Semrush keyword research helps you find terms people use in search engines.
You can enter a search term and study important data such as search volume, keyword difficulty, intent, competition, and related terms.
One popular feature is the Keyword Magic Tool. It can help you discover targeted keywords and related ideas for your content.
For example, if you sell running shoes, you might research:
- Running shoes
- Best running shoes
- Men’s running shoes
- Trail running shoes
- Running shoes for beginners
You can then choose specific keywords that match your product or service.
Good keyword research is not about choosing the term with the highest search volume. The keyword should also match your audience and SEO strategy.
2. Semrush Competitor Analysis
Semrush competitor analysis helps you understand how other websites perform.
You can enter your domain or a competitor’s domain and study areas such as:
- Organic keywords
- Top pages
- Search visibility
- Backlinks
- Competitor traffic
- Advertising activity
This type of competitor research can reveal useful content gaps and keyword gaps.
For example, you may discover that several competitors rank for an important topic that your website has not covered.
You can use that information to create original and more useful content.
3. Semrush Site Audit
Technical problems can make it harder for search engines to understand your website.
Semrush Site Audit checks a website for many common problems.
These can include:
- Broken links
- Crawlability issues
- Duplicate content
- HTTPS problems
- Metadata issues
- Internal linking problems
- Website performance
- Indexing issues
Regular audits can support technical SEO and help you decide which problems should be fixed first.
Site Audit is especially helpful for larger websites where checking every page manually would take too much time.
4. Semrush Rank Tracking
Rank tracking helps you monitor how selected keywords perform over time.
You can follow keywords ranking for your website and see whether positions improve or decline.
You may also track:
- Competitor movements
- Location-based rankings
- Visibility changes
- Keyword opportunities
A keyword may appear differently across the search engine results page depending on location, device, competition, and other factors.
You can also monitor some SERP features that appear beyond standard organic listings.
Rankings should not be your only measure of success. Traffic, leads, sales, engagement, and conversion rate can also matter.
5. Semrush Backlink Analysis
Links from other websites can play an important role in SEO.
Semrush provides backlink analysis tools that help you study a website’s backlink profile.
You can examine links pointing to your website or research links earned by competitors.
This can help you discover possible link-building opportunities.
However, do not focus only on the number of backlinks. Link relevance, quality, and context are also important.
A smaller number of useful links can be more meaningful than a large number of unrelated links.
6. Content Optimization
Semrush also provides tools for content optimization.
These tools can help marketers research topics and improve content based on search competition and related terms.
For example, before writing a new page, you can research:
- Relevant keywords
- Search intent
- Competing pages
- Related topics
- Content gaps
This information can guide your content plan.
You can also review existing landing pages and articles to find possible areas for improvement.
SEO recommendations should still be applied naturally. Content should be written for real readers rather than simply adding as many keywords as possible.
7. AI Search Visibility
Search is changing as people increasingly use AI-powered platforms to find information.
Semrush now includes AI search visibility features. These can help marketers understand how brands appear across AI-powered search experiences.
The platform’s AI features cover services such as ChatGPT, Gemini, Perplexity, Claude, and AI Overviews.
This can help businesses study how their brand or content appears in an AI answer.
Traditional SEO mainly focuses on the search engine results page SERP. AI visibility adds another area to monitor because users may also receive information through AI generated answers.
8. Finding Keyword and Content Gaps
Semrush includes analysis tools that can help uncover opportunities competitors already target.
A keyword gap can show search terms that competing websites rank for while your website does not.
A content gap works in a similar way. It can reveal topics that may be missing from your website.
This does not mean you should copy competitors.
Instead, ask whether the missing topic is useful to your audience.
If it is, you can create an original page that answers the searcher’s needs more clearly.
9. Can I Use Semrush for Free?
Yes. A Semrush free account is available.
According to the source material, the free plan does not require a credit card and provides one demo project and 10 reports per day across vital tools. Its limits are much lower than paid plans.
A free account can be useful if you are a beginner and want to explore the platform before paying.
For regular professional work, larger projects, or deeper research, you may need higher limits.
10. Semrush Pricing
Semrush pricing varies depending on the plan and features you need.
The platform provides paid options with higher limits than its free account. Different levels are designed for freelancers, teams, agencies, and larger organizations.
Before choosing a plan, consider:
- Number of websites
- Number of keywords
- Competitor research needs
- Reporting requirements
- Team size
- SEO workload
Do not choose a plan only because it has more features. Choose one that fits your actual workflow.
Semrush Affiliate Program
The Semrush affiliate program provides another way for eligible publishers and creators to work with the platform.
Semrush runs its affiliate program through Impact. Partners can promote eligible Semrush products through tracked referral links.
The source material states that commissions can reach $300 for a Semrush One sale, while actual commissions depend on the product and partner tier.
The program may be relevant to bloggers, publishers, educators, video creators, and online communities.
Affiliate earnings are not guaranteed. Results depend on your audience, traffic, content, and qualifying referrals.

How to Use Semrush for a Basic SEO Strategy
A beginner does not need to use every feature at once.

- Find related search terms.
- Check competitors.
- Look for keyword and content gaps.
- Create useful content.
- Run a technical site audit.

This gives you a simple SEO strategy without making the process too complicated.
Can Semrush Be Trusted?
Semrush is an established SEO and digital marketing platform.
However, its keyword, traffic, and competitor metrics should not be treated as exact Google data.
Third-party SEO platforms use their own databases, estimates, and methods. Actual website results can be different.
For important decisions, compare third-party data with first-party sources when available.
The source material also recommends using sources such as Google Search Console and Google Analytics alongside Semrush data.
