It is an all-in-one digital marketing platform for SEO, competitor research, content, PPC (pay-per-click), and AI search visibility. By the end of this guide, you will know exactly what Semrush does, how its main tools work, and whether it fits your budget. You will also understand its metrics, its pricing, and its newer AI visibility tools. Most articles explain the features but skip two things: where the data actually comes from, and what each metric really means.
This guide fixes both. Reading it takes about ten minutes. Testing Semrush itself is free to start, since it offers a limited free account and trial access on eligible toolkits.
Quick Answer
Semrush is a subscription-based digital marketing platform used for SEO, keyword research, competitor analysis, rank tracking, backlinks, content, PPC (pay-per-click), and AI search visibility. Marketers use it through a browser to research their own website and rivals, then plan and monitor improvements. Paid plans start at $139.95 per month, with a limited free account.
What Is Semrush?
Semrush is a subscription-based digital marketing software platform. It brings SEO, content, advertising, market research, local marketing, social media, and AI visibility tools together in one place. You do not download anything. It is software as a service, so you log in and work through a web browser.
The platform gives you two kinds of information. First-party project data comes from your own website and connected accounts. Competitive intelligence is estimated from large databases. This means you can research your own domain and study competitor domains you do not own.
Semrush started life mainly as an SEO tool. It has grown into a wider brand-visibility platform, an digital marketing platform that now covers everything from keyword rankings to how often AI answers mention your brand. When people ask what Semrush is in digital marketing or what the Semrush tool does, the short version is simple: it is a research and tracking suite for anyone who wants more visibility online.
What Does Semrush Do?
Before the feature list, here is the point of the platform. Semrush helps you find opportunities, spot problems, and track progress across search and AI. It answers the everyday questions of a marketer: what should I target, who am I up against, and is my work paying off?
What is Semrush used for, in practice? It helps users:
- Discover keywords and understand search intent.
- Analyze organic and paid competitors.
- Track keyword positions over time.
- Audit technical SEO problems on a site.
- Review backlink profiles and link quality.
- Estimate website traffic for any domain.
- Find content gaps and plan new pages.
- Monitor local search performance.
- Research PPC campaigns and ad copy.
- Measure brand mentions in AI-generated answers.
- Build automated client and stakeholder reports.
Here is one quick example. An online store could use Semrush to find product keywords, identify competing stores, detect technical problems, monitor rankings, and discover sites that might provide backlinks. One platform, one workflow, from research to reporting.
Keyword research is foundational, but it’s really audience research. You are finding out the exact language your potential customers use.
How Does Semrush Work?
How does Semrush work day to day? The process breaks into four simple stages.
1. Enter something to research
Type in a domain, URL, keyword, market, or competitor name.
2. Pick your database
Choose the country or search database that matches your target market.
3. Read the results
Review Semrush metrics, trends, and recommendations for that query.
4. Create a Project
Set up a Project to track ongoing performance for a site you manage.
There is a key difference between two modes. Research reports let you analyze almost any public domain or keyword, based largely on Semrush databases and estimates. This is ideal for competitive research. Projects let you monitor a website over time using crawled data and connected accounts. Projects power audits, tracking, and reporting.
You can connect Google Analytics and Google Search Console for extra first-party information. This mixes real data from your site with the platform’s wider estimates. After you set up your Semrush login and first project, the whole Semrush guide workflow becomes routine within a week.
Key Semrush Features and Their Uses
Every tool below does one thing well. Below you’ll find what each one does, what it shows you, and one real way to use it. If you want the deeper version usage limits, what’s inside each report, and which plan unlocks what go to our full guide to Semrush features.
Keyword Research and Keyword Magic Tool
The Semrush Keyword Magic Tool is the core of Semrush keyword research. It gives keyword ideas, search volume, search intent, Keyword Difficulty, CPC, competitive density, related questions, SERP features, and saved keyword lists. Use it for a full Semrush keyword search when planning a content calendar. If you have wondered what the Semrush keyword tool is, this is it: your starting point for finding terms worth targeting and checking Semrush search volume before you write.
Competitor and Keyword Gap Analysis
This set finds who competes with you and where you can win. It shows organic competitor discovery, plus shared, missing, weak, strong, and untapped keywords. It reveals competitor ranking pages and paid-search comparisons. So what is keyword gap in Semrush? The Semrush Keyword Gap Tool compares several domains and shows terms your rivals rank for that you do not. These Semrush features for competitor analysis turn guesswork into a clear target list. Semrush isn’t the only tool pulling this data, and the numbers don’t always match between platforms. If you want to see whose keyword and backlink data holds up best, we put all three side by side in our ahrefs vs spyfu vs semrush comparison.
Site Audit and On-Page SEO Checker
The Site Audit crawls your website and flags issues. It checks crawlability, broken links, duplicate content, HTTPS problems, Core Web Vitals-related signals, and internal linking. The On-Page SEO Checker adds prioritized recommendations for each page. Review these before you change a live site, since automated advice can miss context that only you know.
Position Tracking
What is position tracking in Semrush? It monitors your chosen keywords every day. You can track by country, city or ZIP code, device, search engine, competitor, and SERP feature. This is the heart of Semrush rank tracking. It also feeds the visibility metric, so if you ask what is visibility in Semrush, it is the estimated share of clicks your tracked rankings could earn.
Backlink Analytics and Link Building
Backlink analytics shows referring domains, anchor text, new and lost backlinks, and toxic-link indicators. The Backlink Gap finds domains linking to rivals but not you. Link-building tools then surface prospects to contact. You can also study Semrush subdomain backlinks and check the Semrush Authority Score to gauge a domain’s overall strength.
Traffic Analytics and Market Research
Traffic data here is estimated. It is built for comparison, not accounting-level accuracy. You see visits, unique visitors, engagement, traffic sources, geographic distribution, and audience overlap between sites. Use this to size up a market or check yourself against a competitor. One thing to keep in mind: traffic estimates are estimates, and the two tools use different methods to get them. We break down which one gets closer to real numbers in our Semrush vs Similarweb comparison.
Content, PPC, Local and Social Tools
The wider suite covers SEO content briefs and optimization, advertising research, PLA (product listing ad) research, Google Business Profile tools, social publishing and tracking, and reporting. These extend Semrush beyond core SEO into full-funnel marketing.
Important Semrush Metrics Explained
Metrics only help if you read them correctly. Here is what each one means and how to use it.
| Metric | What it means | How to read it |
|---|---|---|
| Search volume | Estimated monthly searches | A demand indicator, not an exact count |
| Keyword Difficulty (KD) | Estimated difficulty of reaching Google’s top results | Higher scores need stronger pages and authority |
| Position | A domain’s ranking for a keyword | Compare by location, device, and date |
| Visibility | Estimated share of potential clicks from tracked rankings | Best for watching change over time |
| Authority Score | Semrush’s comparative domain-quality score | Compare similar sites; it is not a Google metric |
| Traffic cost | Estimated cost to buy the same organic traffic through ads | Use for relative comparison only |
| Branded traffic | Traffic from searches containing a brand name | Separates brand demand from new discovery |
| SERP features | Enhanced Google result types | Includes snippets, image packs, and maps |
So what is KD in Semrush, or what is keyword difficulty in Semrush? Both refer to that difficulty score. What is a good Authority Score on Semrush, what is Semrush rank, what is traffic cost in Semrush, what is volume in Semrush, and what is branded traffic in Semrush all point back to this table. And if you ask what SERP features in Semrush are, they are the special result boxes above the plain blue links.
What Is Semrush AI Visibility?
AI visibility is the newer side of the platform. It is not traditional SEO. It measures how your brand shows up inside AI-generated answers from tools like chatgpt, Gemini, and Google AI Mode. So what is AI visibility in Semrush? It is a set of tools that track your presence in AI search, not just Google’s blue links. For a closer look at the assistants people actually use, browse our ai chat tools collection.
The Semrush AI features cover an AI Visibility Score, brand mentions in AI answers, competitive AI visibility, Prompt Research, Prompt Tracking, citation analysis, brand sentiment, AI crawler accessibility checks, and gap-spotting where rivals appear but you do not. These Semrush AI visibility products sit inside the AI Visibility Toolkit. If ChatGPT is not the assistant you rely on, our chatgpt alternatives guide covers the rest.
The scale here is real. Semrush’s 2026 AI Visibility Index analyzed 126 million US AI search prompts from January through April 2026, up from just 2,500 prompts at its September 2025 launch. That growth shows how fast AI search has become a serious channel. For the official reference, see th ai visibility resources.
What Is Prompt Volume in Semrush?
Prompt volume estimates demand around AI-search topics. Semrush models it from clickstream data. For example, it may estimate that far more people ask AI to compare two products than ask about a product’s history. Use prompt volume to prioritize subjects. Do not treat it as an exact count of every prompt typed into AI tools.
What Is Semrush AI Citation Analysis?
Semrush AI citation analysis identifies the sources and domains that AI answers cite. It helps you see which content earns AI references and which pages of yours get pulled into answers. This matters because citation patterns differ by platform. Knowing who gets cited helps you build content that AI systems trust and quote.
Where Does Semrush Get Its Data?
This is the part most guides skip. Knowing the source of a number tells you how much to trust it. Semrush combines several inputs:
- Proprietary web crawlers, including Bot
- Search results databases
- Machine-learning models
- Anonymous clickstream information
- Trusted third-party data providers
- Connected Google Analytics and Search Console accounts
- Your own tracking projects
The important distinction is between measured and modeled data:
- Keyword and competitive traffic figures are estimates.
- Position Tracking observes the exact keywords and settings you choose.
- Site Audit crawls the specific website you configure.
- Connected analytics give you real first-party website data.
- AI prompt data uses modeled datasets and AI-search clickstream signals.
One honest limitation matters here. Semrush should complement Google Analytics and Search Console, not replace them. Your connected Google tools remain the source of truth for your own traffic. Semrush shines at competitor comparison, where Google gives you nothing. For other platforms that estimate traffic and audience, browse our data analytics tools hub.

Conclusion: Is Semrush Worth Using?
Semrush is a comprehensive digital marketing platform for businesses that need more than basic keyword research. Its strongest value comes from combining SEO audits, competitor analysis, rank tracking, backlinks, content research, PPC data, and AI visibility in one system. Its estimated metrics need context, and its price is hard to justify for occasional users. Agencies, marketing teams, and growing businesses get the most value. Beginners should test the free account or a trial before choosing a paid plan.
Imperial AI Tools take: If you still ask what is Semrush and whether it fits you, here is our view. Start on the free account, connect your own site, and run one Site Audit and one Keyword Magic search. That single hour tells you more than any review. Semrush earns its price once you use competitor data and rank tracking every week. For a lone blogger, a cheaper focused tool often does the job. For a team, few platforms match its depth.
