SEMrush is one of the most comprehensive SEO suites on the market, but its breadth and paid plans can exceed the needs of a focused keyword-research workflow. Check the official site for current pricing.
Unless you're running a large agency managing dozens of clients, that's a hard bill to justify.
The good news: most SEOs use only a fraction of SEMrush's features — mainly keyword research, SERP analysis and basic competitor tracking. These exact features are available at a fraction of the price, or completely free.
Here are the best cheap SEMrush alternatives in 2026.
What do people actually use SEMrush for?
SEMrush does a lot. But survey any SEO and they'll tell you the most-used features are:
- •Keyword research — volume, KD, intent, suggestions
- •Competitor analysis — what keywords is a competitor ranking for?
- •SERP analysis — who's on page 1 and how strong are they?
- •Position tracking — is my site moving up or down?
- •Technical audit — crawl errors, missing tags, slow pages
For features 1–3, multiple free and cheap tools compete directly with SEMrush. For 4–5, you need a paid tool — but not necessarily SEMrush.

The best SEMrush alternatives by use case
Best for keyword research: Serpvox
Serpvox is purpose-built for a focused keyword-research workflow: discovering queries, comparing relative trend interest and estimated difficulty, and analysing the SERP.
| Feature | SEMrush | Serpvox | |---|---|---| | Demand signal | Provider metric | Relative Trends interest | | Keyword Difficulty | ✅ | ✅ | | SERP Top 10 | ✅ | ✅ | | 12-month trend | ✅ | ✅ | | Search intent | ✅ | ✅ | | Related + question keywords | ✅ | ✅ | | Domain overview | ✅ | ❌ | | Backlink audit | ✅ | ❌ | | Price | Check provider | Free / €19/month |
If keyword research is your primary use case, Serpvox may cover the narrower workflow at a lower cost. Verify current prices and features on both providers' official pages.
Best for competitor analysis: SEMrush Free / Ahrefs Free Tier
SEMrush offers a free plan with 10 keyword/domain searches per day. It's enough for quick competitor checks (what keywords is this site ranking for?) without paying.
Ahrefs Webmaster Tools is free for your own sites and shows organic traffic, top keywords and backlinks. For competitor analysis you need a paid plan.
Best for SERP analysis: Serpvox
SEMrush's SERP analysis shows the top 10 results for any keyword with domain authority scores. Serpvox does the same with PageRank data — and highlights "attackable" positions where competitors have weak domain authority.

Best for rank tracking: SERPWatcher / Google Search Console
Google Search Console (free) tracks your site's keyword rankings with actual Google data. Not as visual as SEMrush, but 100% accurate.
SERPWatcher by Mangools is focused on rank tracking. Verify its current price and limits on the official site before comparing it with a suite.
Best for technical audits: Screaming Frog (free up to 500 pages)
Screaming Frog SEO Spider is free for up to 500 pages and covers 90% of technical SEO audit needs: broken links, duplicate titles, missing metas, redirect chains.
The paid version is £199/year — far cheaper than SEMrush for this specific use case.
SEMrush vs Serpvox: direct comparison for keyword research
If your main job is finding and evaluating keywords, here's how the two compare:
SEMrush Keyword Magic Tool:
- •20+ billion keyword database
- •Very accurate volume data
- •Competitor keyword gap analysis
- •CPC and paid search data
- •Check current price on SEMrush
Serpvox:
- •Real-time Google Autocomplete + Trends data
- •PageRank-based KD score with SERP breakdown
- •Full SERP top 10 with attackable opportunity badges
- •12-month trend chart built in
- •Google Search Console integration
- •Free (3/day) · Pro €19/month
The bottom line: if you need deep competitor intelligence and a massive keyword database, SEMrush is the broader product. If you need focused keyword discovery and SERP context, Serpvox is the narrower option.

Frequently asked questions
Is there a free version of SEMrush? Yes — SEMrush offers a free plan with 10 keyword/domain searches per day and limited features. Enough for occasional checks, but too restricted for regular keyword research.
What is the cheapest SEMrush alternative? Serpvox starts free (3 searches/day) and its Pro plan costs €19/month. Compare that focused scope with SEMrush's current official plans rather than relying on a static third-party price.
Does Serpvox have competitor analysis like SEMrush? Serpvox focuses on keyword research and SERP analysis rather than full competitor domain analysis. For domain-level competitor research, combine Serpvox with the free tiers of SEMrush or Ahrefs.
Conclusion
SEMrush is a powerful tool — but it's priced for enterprise teams managing multiple clients with large budgets. For the majority of SEOs focused on content and keyword strategy, you're paying for features you'll never use.
Serpvox gives you the core keyword research and SERP analysis at €19/month. Start free to see if it covers your needs.
