The honest comparison: Semrush is bigger, more powerful, and more comprehensive. Moz is simpler, more approachable, and significantly cheaper at its entry tier. The right choice depends less on which tool is "better" in the abstract and more on what kind of SEO work you actually do and how deep your budget goes.
This guide breaks down every category that matters — keyword database size, backlink analysis depth, site audit capability, pricing, and ease of use — with real numbers so you can make a confident decision before spending $100 to $500 a month on an SEO tool.
⚡ WorkflowVerdict: Semrush wins for serious SEOs — Moz wins for beginners and DA-focused workflows
If you're doing competitive research, content gap analysis, PPC intelligence, or managing SEO for multiple clients — Semrush is the stronger tool at every level. Moz earns its place for bloggers, small business owners, and teams that want a simpler interface and trust Moz's Domain Authority as a core metric. For most serious SEO professionals in 2026, Semrush is the default recommendation.

Pricing: Moz Is Cheaper — Semrush Gives You More for the Money
Moz has a clear pricing advantage at the entry level — its Starter plan at $49/month is the most affordable serious SEO tool in the market. But the features available at that price are limited enough that most users end up on the Standard plan at $99/month or Medium at $179/month to get meaningful functionality.
Semrush starts at $117/month (billed annually) and feels expensive until you compare what that price includes — 55+ tools covering keyword research, competitive intelligence, backlink analysis, site auditing, content marketing, rank tracking, PPC research, and more. At equivalent capability levels, the price gap between the two platforms narrows significantly.
Semrush Pricing (2026)
| Plan | Monthly | Annual (per mo) | Key Limits |
|---|---|---|---|
| Pro | $139.95 | ~$117 | 5 projects, 500 tracked keywords, 10,000 results per report |
| Guru ⭐ Recommended | $249.95 | ~$208 | 15 projects, 1,500 tracked keywords, historical data, Content Marketing Toolkit |
| Business | $499.95 | ~$417 | 40 projects, 5,000 tracked keywords, API access, Share of Voice |
Moz Pro Pricing (2026)
| Plan | Monthly | Annual (per mo) | Key Limits |
|---|---|---|---|
| Starter | $49 | $49 | 1 user, 1 tracked domain, 50 tracked keywords, 20K pages crawled |
| Standard | $99 | $79 | 1 user, 3 tracked domains, 300 tracked keywords, 400K pages crawled |
| Medium | $179 | $143 | 2 users, 10 tracked domains, 1,500 tracked keywords, 2M pages crawled |
| Large | $299 | $239 | 3 users, 25 tracked domains, 3,000 tracked keywords, 5M pages crawled |
Keyword Research: Semrush Has 25x More Keywords
This is where the gap between the two platforms is most stark — and most consequential. Semrush's keyword database contains over 25 billion keywords across 142 geographic databases. Moz's database contains approximately 1 billion keywords. That's not a marginal difference — it's a different order of magnitude.
In practice, this means Semrush surfaces long-tail keywords, question-based queries, and niche variations that simply don't exist in Moz's database. For content strategists building topical authority across hundreds of articles, this depth matters enormously. For a blogger writing 5 posts a month, the gap is less relevant — Moz's 1 billion keywords still covers the vast majority of common queries.
| Feature | Semrush | Moz Pro |
|---|---|---|
| Total keyword database | 25+ billion | ~1 billion |
| Geographic databases | 142 countries | Limited |
| Keyword difficulty score | ✅ Yes | ✅ Yes |
| Search intent data | ✅ Yes | ❌ Limited |
| Keyword gap (competitor comparison) | ✅ Yes | ❌ No |
| Question-based keyword filtering | ✅ Yes | ⚠ Limited |
Verdict: Semrush — clearly. 25x the keyword database, search intent data, and keyword gap analysis make Semrush the more powerful keyword research tool by a significant margin.
Backlink Analysis: Similar Size — Semrush Updates Faster
Backlink analysis is where Moz historically built its reputation — and it remains competitive in database size. Moz's Link Explorer indexes approximately 40 trillion links. Semrush's backlink database has over 43 trillion. On raw volume, they're broadly comparable.
The difference is in update frequency and additional data. Semrush updates its backlink database more frequently and provides more contextual data per link — including anchor text analysis, link type (follow/nofollow/sponsored/UGC), first seen and last seen dates, and authority score for the linking domain. Moz's Link Explorer is solid for bulk backlink discovery but shows its age in how the data is presented and how frequently it refreshes.
Moz's Domain Authority (DA) metric remains widely used in the industry — particularly in outreach and link building, where publishers quote DA scores as a standard benchmark. Semrush uses its own Authority Score, which is methodologically sound but less universally recognised. If your link building workflow depends on DA scores, Moz is the native source.
Site Audit: Semrush Goes Deeper — Moz Is Easier to Read
Semrush's Site Audit tool is one of the most comprehensive technical SEO crawlers available at any price point. It checks 140+ technical issues including Core Web Vitals, crawlability, HTTPS configuration, internal linking structure, duplicate content, page speed, structured data errors, and more. Results are categorised by severity and paired with specific fix recommendations. For technical SEO professionals managing complex sites, Semrush's site audit is an industry-standard tool.
Moz's site crawl is solid but less granular. It covers the essential technical issues — broken links, redirect chains, missing meta tags, duplicate content, and crawlability problems — and presents them in a cleaner, more approachable interface. For site owners who aren't deeply technical, Moz's audit is actually easier to act on. For SEO professionals who need to find every issue, Semrush's depth wins.
Verdict: Semrush for technical depth. Moz if your client or team needs clear, jargon-free audit reports that non-technical stakeholders can understand.
Competitor Analysis: Semrush Has No Rival Here
This is Semrush's strongest category — and it's where the gap with Moz is largest. Semrush's competitive intelligence tools go well beyond standard SEO comparison. You can analyse a competitor's entire organic keyword portfolio, see which keywords they rank for that you don't (keyword gap), examine their paid search strategy including the ad copy and keywords they're bidding on, see their display advertising placements, and estimate their traffic share in any category.
Moz's competitor analysis is basic by comparison. You can compare domain metrics and keyword overlap, but there's no PPC intelligence, no traffic estimation beyond ranking data, and no display advertising visibility. For agencies and content marketers who build strategies based on competitive intelligence, Moz simply doesn't have the tools that Semrush provides.
Verdict: Semrush — decisively. There is no meaningful comparison in this category.
Ease of Use: Moz Wins for Beginners — Semrush Is Worth the Learning Curve
Moz was designed with approachability in mind. The interface is clean, the metrics are well-explained, and the learning curve is gentle enough that a blogger with basic SEO knowledge can be productive within an hour. Moz's Q&A community and Whiteboard Friday content library also make it one of the best platforms for learning SEO while using the tool.
Semrush has 55+ tools — and that breadth can feel overwhelming when you first log in. Navigating between the keyword magic tool, position tracking, site audit, backlink analytics, and competitive research requires more time to learn. That said, once familiar, Semrush's depth becomes an advantage rather than a burden. Most professional users report that the learning investment pays back quickly in capability gained.
“I started with Moz and it was great for learning SEO basics. But once I started doing real competitive work for clients, I switched to Semrush and never looked back. The data depth is in a different league.”
— Freelance SEO consultant, verified G2 review
Verdict: Moz for beginners who want a gentle introduction to SEO tools. Semrush for anyone doing SEO professionally — the learning curve is manageable and the payoff is substantial.

Final Verdict
Semrush
4.7 / 5
Best for serious SEOs & agencies
Moz Pro
3.8 / 5
Best for beginners & DA-focused workflows
Moz built the foundations of modern SEO metrics and still earns its place in specific workflows — particularly for teams where Domain Authority is a reporting standard and budget is a primary constraint. The $49 Starter plan remains one of the most accessible entry points in the SEO tools market.
But for any SEO professional doing serious work in 2026 — competitive research, content gap analysis, technical auditing, PPC intelligence, rank tracking at scale — Semrush is the stronger platform in almost every measurable way. The 25x keyword database advantage alone changes what's possible in keyword research. The competitor intelligence tools have no equivalent in Moz. And at equivalent capability tiers, Semrush is often the better value despite its higher headline price. If you're ready to invest in your SEO toolkit properly, Semrush is the right choice.

Is Semrush better than Moz?

At equivalent capability tiers — Moz Medium at $143/month vs Semrush Pro at $117/month — Semrush is actually cheaper and significantly more powerful. For full pricing details, see our Semrush pricing breakdown.
Does Semrush have Domain Authority like Moz?
Semrush uses its own Authority Score (AS) metric instead of Moz's Domain Authority (DA). Both measure domain-level link authority on a 0–100 scale, but they use different methodologies and produce different scores for the same domain. Moz's DA is more widely recognised in the industry — particularly in link building outreach, where publishers often quote DA as a standard benchmark. If DA is critical to your workflow, Moz is the native source.
Can Moz replace Semrush?
For basic SEO needs — rank tracking, backlink monitoring, site auditing, and keyword research on common queries — Moz can cover the fundamentals. But Moz cannot replace Semrush for competitive intelligence depth, keyword research at scale (Semrush has 25x more keywords), PPC research, content marketing tools, or social media analysis. Teams that switch from Semrush to Moz to save money typically find themselves missing the competitive data they relied on.
Which is better for beginners — Semrush or Moz?
Moz is better for SEO beginners. Its interface is cleaner, its metrics are better explained within the tool, and its educational resources (Whiteboard Friday, Moz Academy, Beginner’s Guide to SEO) make it an excellent platform for learning SEO while doing it. Semrush's broader feature set can feel overwhelming for new users. That said, Semrush's learning curve is manageable within a few weeks — and many professionals recommend starting on Moz and upgrading to Semrush when you outgrow it.
