If you're serious about SEO, competitor research, content marketing or improving your visibility in search, having the right tools can save a huge amount of time. Semrush is one of the most comprehensive digital marketing platforms available, bringing keyword research, competitor analysis, site auditing, rank tracking and AI search visibility into one ecosystem.

Rather than using a collection of separate tools, Semrush lets marketers research opportunities, identify technical problems, track rankings and analyse competitors from a central dashboard.

But Semrush isn't a cheap tool, particularly for freelancers and smaller businesses. So what exactly do you get, and which Semrush product is worth paying for?

What Is Semrush?

Semrush is an all-in-one digital marketing platform built around search visibility and competitive intelligence.

Its tools can help you discover keywords, analyse competing websites, research backlinks, audit technical SEO issues, monitor rankings and develop content strategies. Semrush has also expanded into AI search visibility, allowing businesses to track how brands and websites appear across platforms such as ChatGPT, Gemini, Perplexity and Google AI Overviews.

That makes it useful for more than traditional Google SEO.

Whether you're running an affiliate website, an e-commerce store, a SaaS business or an agency, the platform can provide data for planning and measuring organic growth.

Semrush Keyword Research

One of the platform's biggest strengths is keyword research.

The Keyword Magic Tool provides keyword suggestions alongside metrics such as search volume and keyword difficulty. This can help you find both high-volume terms and less competitive long-tail opportunities.

For example, instead of targeting a broad keyword such as "running shoes", you can use keyword research to uncover more specific searches around particular brands, features, prices or use cases.

This is useful when building content calendars because you're not simply guessing what people might search for.
 

Competitor Research

Semrush is also designed to help you understand what competitors are doing.

Its competitor analysis tools can show information around competitors' traffic, rankings, keywords, backlinks and advertising activity.

For affiliate marketers, this can be particularly valuable.

You can research competing websites, identify keywords they rank for and look for gaps where your own website may have an opportunity to compete.

The goal isn't simply to copy another website. Instead, competitor data can help you understand what topics and search terms are already generating visibility within your market.

Site Audit

A website can have great content and still struggle in search because of technical problems.

Semrush's Site Audit tool crawls a website and identifies issues that may affect search performance, including broken links, crawlability problems and other technical SEO concerns.

The tool can be useful for both beginners and experienced SEO professionals because it gives you a structured list of problems to investigate.

The number of pages you can crawl depends on your subscription. The current Pro-level SEO Toolkit limit is 100,000 pages per month.

Rank Tracking

Knowing whether your SEO work is actually producing results is essential.

Semrush's position tracking tools allow you to monitor keyword rankings and changes over time. The platform can track traditional search visibility as well as newer AI search environments.

This makes it possible to monitor important keywords rather than relying on occasional manual Google searches.

For agencies and larger websites, tracking multiple locations, devices and keywords can be particularly useful.

Backlink Analysis

Backlinks remain an important part of SEO, and Semrush includes tools for researching backlink profiles.

You can analyse links pointing to your own website and investigate competitors' backlink profiles to identify potential opportunities. Semrush also increasingly connects backlink analysis with AI citations and brand visibility.

This can help you understand not only who links to competing websites but also where your own website may have authority gaps.

Semrush for Content Marketing

Semrush isn't only a research platform.

Its feature set includes tools designed to help marketers develop content ideas, create briefs and optimise existing pages. Semrush says its content tools can generate SEO-focused articles from a brief and help optimise content for target keywords and AI search prompts.

For content-heavy websites, this can bring research and optimisation into the same workflow.

However, automated content should still be reviewed and edited by a human. Search visibility depends on usefulness and quality, not simply inserting keywords into an article.

Semrush Pricing

Semrush has changed its product structure, so it's important not to rely on older articles that only mention the traditional Pro, Guru and Business plans.

Semrush's current pricing includes SEO + AI Search plans, while the older SEO Toolkit plans remain available to existing customers but are no longer sold to new customers.

Current SEO + AI Search Pricing

Annual-billing prices are shown as monthly equivalents and are billed annually. Semrush currently advertises savings of up to 17% with annual billing.

The SEO plan is aimed at freelancers and small businesses and includes keyword research, competitor analysis, position tracking, Site Audit and AI-search performance monitoring.

The Starter plan adds broader SEO and AI visibility capabilities, while Pro+ increases website and keyword limits and adds features such as historical SEO data, content optimisation and keyword cannibalisation analysis. Advanced increases the limits further and adds API data integration and SEO Share of Voice.

Is Semrush Expensive?

Compared with basic keyword research tools, yes.

The standard monthly pricing starts at $139 for the current SEO plan, while the broader Semrush One offering starts at $199 per month.

However, comparing Semrush purely against cheap keyword tools isn't particularly useful.

You're paying for a much broader ecosystem covering keyword research, competitor intelligence, technical SEO, rank tracking, backlinks, content and AI visibility.

For someone managing one small website, the cost may be difficult to justify. For an agency or business where SEO directly contributes significant revenue, the wider data set can make the subscription considerably easier to justify.
 

Other Semrush Products

Semrush also offers individual toolkits beyond its core SEO offering.

Current starting prices listed by Semrush include:

• AI Visibility: $99/month
• Traffic & Market: $289/month
• Local: $30/month
• Content: $60/month
• Social: $20/month
• Advertising: $99/month
• AI PR: $149/month

These are separate toolkit starting prices and can vary depending on billing and configuration.

The Advertising toolkit, for example, includes competitor keyword research, Google Shopping research and Google Ads exports, while its Pro tier adds deeper competitor advertising intelligence.

Who Should Buy Semrush?

Semrush makes the most sense for people who use SEO as an important part of their business.

Semrush is worth considering if you:

• Run an SEO-focused website
• Manage affiliate websites
• Work in digital marketing
• Run an SEO agency
• Manage multiple websites
• Need detailed competitor research
• Produce large amounts of content
• Track rankings regularly
• Need technical SEO auditing
• Want to monitor AI search visibility

For a serious SEO operation, having all these capabilities under one subscription can be more convenient than switching between several platforms.

Who Probably Doesn't Need Semrush?

Semrush may be excessive if you're running a very small website and only need occasional keyword ideas.

A beginner who publishes a few articles a month may not use enough of the platform to justify the subscription.

In that situation, free keyword research resources and basic SEO tools may be enough until the website starts generating meaningful traffic or revenue.

Final Verdict

Semrush is one of the more comprehensive SEO and digital marketing platforms available, but its price means it isn't for everyone.

Its strongest advantage is the depth of information available across different areas of digital marketing. You can research keywords, investigate competitors, audit your website, monitor rankings, analyse backlinks and increasingly measure visibility across AI-powered search platforms.

For freelancers and small businesses, the current SEO plan at $139/month is the most straightforward entry point if you primarily need SEO functionality. Those wanting the broader SEO + AI Search ecosystem can consider the higher tiers.

The important thing is to choose based on how much of the platform you'll actually use.

If SEO is central to your growth strategy, Semrush can potentially pay for itself through better research and more informed decisions. If you only need occasional keyword suggestions, however, there are cheaper options.

Overall: Semrush is best suited to marketers, agencies, affiliate publishers and businesses that need serious SEO and competitive research rather than a basic keyword tool.
