Ahrefs is one of the broadest SEO tools on the market, but its paid plans can exceed what freelancers, bloggers and small businesses need. Check the official site for current pricing.
The good news: you don't need Ahrefs for keyword research. In 2026, several free and affordable tools offer the same core features — keyword difficulty, SERP analysis, search volume and trends — at a fraction of the cost.
Here are the best free Ahrefs alternatives, ranked by value.
What does Ahrefs actually offer?
Before comparing alternatives, it's worth understanding what you're replacing:
- •Keyword Explorer: volume, KD, clicks, search intent
- •Site Explorer: backlink profile, organic traffic, top pages
- •Content Explorer: find top-ranking content by topic
- •Rank Tracker: daily keyword position tracking
- •Site Audit: technical SEO crawl
For most SEOs, the first two features — keyword research and SERP analysis — cover 80% of day-to-day work. That's exactly where free alternatives can compete.

2. Ahrefs Webmaster Tools (free, limited)
Ahrefs offers a genuinely free tier called Ahrefs Webmaster Tools — but it only works for websites you own and verify. You can see:
- •Keywords your site ranks for
- •Backlinks pointing to your site
- •Technical SEO issues
Limitation: you can't research competitor keywords or new topics. It's a monitoring tool, not a research tool.
Best for: tracking your existing site's performance alongside another research tool.
3. Google Search Console (free, your site only)
Technically not an Ahrefs alternative, but Google Search Console gives you something Ahrefs can't: real Google data for your own site.
You'll see which keywords you already rank for, with actual clicks, impressions, CTR and average position. The keyword gap between positions 5–20 is often the fastest win in SEO.
Best for: finding quick wins on an existing site. Pair it with Serpvox for new keyword discovery.

4. Semrush Free Plan
Semrush has a free plan with 10 searches per day. Features include:
- •Keyword overview (volume, KD, CPC, trend)
- •Domain overview (limited)
- •Position tracking (limited)
Limitation: access limits and pricing can change, and the interface is complex. Check the provider's official plan page before comparing it with Ahrefs.
Best for: occasional competitive research when you need to check a competitor's domain.
5. Ubersuggest Free Plan
Neil Patel's Ubersuggest offers 3 free keyword searches per day with volume, KD and suggestions.
Limitation: its metrics use a different methodology from other tools, so compare like with like. Features and limits should be checked on the provider's current plan page.
Best for: beginners who want a simple interface and don't need deep accuracy.
6. Moz Keyword Explorer (free tier)
Moz offers 10 free queries per month with their Keyword Explorer. Data includes volume ranges, KD (their own metric) and SERP analysis.
Limitation: 10 searches per month is too little for serious research. The Moz algorithm for KD can differ significantly from actual ranking difficulty.
Best for: occasional spot checks when you're already a Moz user.
Ahrefs vs Serpvox: which one for keyword research?
If your primary need is keyword research (not backlink analysis), here's how they compare directly:
Ahrefs:
- •Enormous keyword database (billions of keywords)
- •Highly accurate volume data
- •Backlink-based KD (more accurate for authority-heavy niches)
- •Daily rank tracking
- •Full site audit
- •Check current price on Ahrefs
Serpvox:
- •Current Google signals (Autocomplete + relative Trends interest + SERP)
- •PageRank-based estimated KD for comparative analysis
- •Full SERP top 10 with "attackable" badges
- •12-month trends built in
- •Google Search Console integration
- •Free plan (3/day) · Pro €19/month
For content creators and small businesses focused on keyword discovery rather than backlink intelligence, Serpvox covers a narrower workflow at a lower price. Check both providers' current plans before comparing costs.

Do you really need Ahrefs?
Yes, if you:
- •Run large-scale link building campaigns
- •Manage SEO for 10+ client websites
- •Need daily rank tracking for hundreds of keywords
- •Require deep technical site audits
No, if you:
- •Focus primarily on content and keyword research
- •Run a blog, personal brand or small business site
- •Have a budget under $50/month for SEO tools
- •Want to find keywords and write content that ranks
For the second group, a combination of Serpvox (keyword research) + Google Search Console (monitoring) + Google Trends (seasonality) covers all the essentials.
Frequently asked questions
Is there a completely free version of Ahrefs? Yes — Ahrefs Webmaster Tools is free but only analyses your own verified sites. For competitor research, you need a paid plan.
What is the best free alternative to Ahrefs for keyword research? Serpvox's free plan includes 3 searches per day with relative trend interest, estimated KD and intent, plus related keywords. Full top-10 SERP analysis is included in paid plans.
Can I do SEO without Ahrefs? Yes, for many focused workflows. Serpvox can support discovery, Search Console provides first-party performance data, and Keyword Planner can validate Ads volume and CPC. Backlink and large-scale competitor research may still require another tool.
Conclusion
Ahrefs is a great tool — but it's built and priced for agencies. If you're a freelancer, blogger or small business owner focused on content and keyword research, you're paying for features you'll never use.
Serpvox offers a focused keyword-research workflow, with a free plan and a €19/month Pro plan. Compare feature scope before treating it as a replacement for a full backlink suite.
