Is Semrush free to use?

Semrush offers a limited free version with a capped number of searches and reports per day, mainly useful for occasional checks. Full access to its keyword, backlink and audit tools needs a paid plan.

What is Semrush mainly used for?

It's used for keyword research, tracking search rankings, auditing a site for technical SEO issues, analysing competitors' traffic and keywords, and researching backlinks, among other marketing research tasks.

Is Semrush good for beginners?

It has a learning curve because of how many tools it includes. Beginners often start with one or two modules, such as keyword research or site audit, rather than trying to use everything at once.

How accurate is Semrush's keyword and traffic data?

Semrush estimates search volume and traffic using its own data models, which is standard practice across SEO tools. Treat the numbers as directional estimates for comparing pages or competitors rather than exact counts.

Semrush vs Google Search Console, what's the difference?

Search Console shows your own site's actual performance data from Google directly, while Semrush estimates rankings, traffic and competitor data more broadly across the web, including sites you don't control. Many marketers use both together.

What is Semrush?

Semrush is a large, all-in-one SEO and marketing research platform used by agencies, in-house marketers and business owners who manage their own website’s search presence. Rather than one narrow tool, it bundles keyword research, rank tracking, technical site audits, backlink analysis and competitor research into a single platform, which is why it’s one of the more recognisable names in SEO tooling. For a business, the core value is being able to see not just how your own site performs, but how it compares to competitors targeting the same keywords.

Key features

Keyword research. Find search terms relevant to your business, along with estimated search volume, competitiveness and related keyword ideas.
Rank tracking. Monitor how your pages rank for chosen keywords over time, across different search engines and locations.
Site audit. Crawl your own website to surface technical SEO issues such as broken links, missing meta tags or slow-loading pages.
Backlink analysis. See which sites link to yours and to your competitors, useful for both link-building strategy and spotting suspicious links.
Competitor research. Compare traffic estimates, top keywords and content gaps between your site and named competitors.
Content and advertising tools. Additional modules cover content optimisation suggestions and paid search research.

How to get started

Sign up at semrush.com and try the limited free searches before choosing a plan.
Add your website as a project to unlock site audit and rank tracking for it specifically.
Run a keyword research search for a topic relevant to your business.
Set up a site audit to catch technical issues worth fixing.
Add one or two competitor domains to compare traffic and keyword overlap.

Who Semrush is for

SEO agencies managing multiple client sites who need one platform covering research, tracking and reporting. In-house marketers at small and medium businesses who handle SEO alongside other duties and want fewer separate tools. And business owners doing their own competitor research before deciding where to invest content or advertising effort.

It also fits teams that want one subscription to replace several narrower point tools, since keyword research, technical auditing, backlink analysis and paid search research are otherwise often spread across separate products.

Tips for getting useful results

Start with one project, not ten. Add your own site first, get comfortable with site audit and rank tracking, then expand to competitors.
Check your own meta tags before running a full audit. Use the free meta tag generator to see what a clean title and description look like.
Preview how a page looks in search results with the free SERP snippet preview before publishing changes based on Semrush’s suggestions.
Treat keyword density as one signal, not a target. Cross-check with the free keyword density checker rather than trying to hit an exact number.

Semrush vs alternatives

SE Ranking covers similar ground — keyword research, rank tracking and site audits — and is generally positioned as a lower-cost alternative for smaller teams that don’t need Semrush’s full breadth. Serpstat is a comparable all-in-one platform, originally built in Ukraine, that’s often chosen for similar reasons around cost and a simpler interface. Surfer SEO is narrower by design, focused specifically on optimising individual content pieces against top-ranking competitors rather than full-site auditing and tracking. Semrush’s advantage over all three is generally the depth and size of its data across markets and the breadth of modules in one subscription.

Is Semrush worth it?

For agencies or businesses that need one platform covering keyword research, rank tracking, technical audits and competitor analysis, Semrush’s breadth is genuinely hard to match, and the free version is enough to judge whether the interface and data suit your workflow. Smaller sites or solo marketers who only need one or two of these functions may find a narrower, lower-cost tool covers their needs just as well. Compare it against the other SEO options in the deals catalog before committing to a plan.
