How to choose
What Semrush is good at – and where it stops
Semrush is the broadest all-in-one in SEO: keyword research, backlinks, rank tracking, site audits, PPC and content tooling in one subscription. That breadth is the point – and the problem. If all you need is a clean diagnosis of your own site, most of what you pay for goes unused, and the free tier caps almost everything that matters.
- Good at: competitor research, keyword and backlink databases, PPC data, agency reporting.
- Stops at: price for a single site (Pro was $139.95/mo at the time of writing), a heavy interface, and a free tier you cannot really audit with.
- Best for: agencies and teams running many sites who need competitor and PPC data regularly.
The best Semrush alternatives, in detail
GSA Website Audit
Free and no signup: sample up to five pages and get a prioritised list across metadata, headings, content, internal links, images, indexability, speed and AI-readiness. Best when you want a fast, actionable diagnosis before paying for anything. Trade-off: a sample, not a full crawl.
Google Search Console
Free and essential for your own site – real queries, impressions, clicks and Core Web Vitals field data. It shows symptoms, not fixes, so pair it with an audit. Best for first-party data.
Ahrefs
Strongest on backlinks and keyword data, with a clean interface. Free tier is limited; paid starts around $129/mo. Best when links and keywords are your bottleneck.
Screaming Frog
A desktop crawler, free up to 500 URLs. Unbeatable for technical depth on larger sites; steeper learning curve and no query data.
Sitechecker
Site audits, rank tracking and uptime monitoring in one. Free tier is capped; paid from about $49/mo. Good for ongoing monitoring on a budget.
Seobility
Generous freemium with a strong on-page focus and monitoring. Free tier caps features; paid from about $50/mo.
Moz Pro
Domain metrics and link data with a familiar brand. Paid from about $99/mo; less useful for a small single-site owner.
Which Semrush alternative fits your job?
- Quick, free diagnosis: GSA Website Audit.
- Your own query data: Google Search Console.
- Backlinks and keyword research: Ahrefs, or Semrush if you already pay for it.
- Deep technical crawl: Screaming Frog.
- Ongoing monitoring on a budget: Sitechecker or Seobility.
How to switch from Semrush without losing anything
- Export your keyword lists, tracked positions and backlink reports before you cancel.
- Keep Google Search Console connected – it is free and gives you first-party query data no tool can replace.
- Recreate your tracked keywords in the cheaper tool, or track them in Search Console where possible.
- Run a fresh audit after switching to confirm nothing regressed on your priority pages.
When Semrush is still worth it
If you run an agency, manage many sites, or lean on PPC and competitor data every week, Semrush earns its price. The alternatives above win when the job is narrower – diagnosing one site, fixing it, and moving on.
