Moz Pro vs Semrush: Features, Data Accuracy, and Price

Semrush is the broader tool: 26 billion keywords, PPC research, content marketing, social, and a keyword database roughly 8x larger than Moz Pro’s. Moz Pro is narrower but easier to learn, with a cleaner UI, Domain Authority as an industry reference score, and better keyword suggestion clustering for beginners. Semrush costs $139.95 per month for the Pro plan. Moz Pro starts at $99 per month for Standard. If you’re doing agency-level work, pick Semrush. If you’re running one site and want to stop second-guessing tool setup, pick Moz Pro.

I’ve paid for both. At the same time. For years. The gap between them isn’t what most comparison articles claim, and it’s not evenly distributed across features. Some things Semrush does 10x better. Some things Moz does cleaner. Let’s get specific.

Quick verdict on Moz Pro vs Semrush

Semrush wins for agencies, PPC teams, and anyone doing competitive intelligence. Moz Pro wins for solo operators, in-house SEOs at smaller brands, and people who want one tool that does 80 percent of the job without a 40-hour learning curve. Both track rankings accurately. Both find backlinks. Both audit sites. The difference is depth versus clarity.

If your week involves analyzing 10+ competitor domains, running PPC campaigns, tracking branded mentions across social, or building content briefs at scale, Semrush earns its price. If your week is 3-5 hours of SEO work on your own site, Moz Pro won’t leave you wanting.

Pricing compared

Semrush charges more for entry access but includes more features per dollar at the top tier. Moz Pro is cheaper to start and cheaper to scale, but caps out lower.

Semrush’s Pro plan at $139.95 is the most popular tier and covers most solo use cases. Moz Pro’s Standard at $99 does the equivalent for less. The price advantage flips at the top: Moz Large at $299 gives you 3,000 tracked keywords, while Semrush Business at $499.95 gives you 5,000 tracked keywords plus API access, Looker Studio integration, and 5 users.

Keyword research: where Semrush pulls ahead

Semrush has the larger keyword database by a factor of 8-10. 26 billion keywords versus Moz’s roughly 3 billion. For long-tail research in non-English markets (German, Portuguese, Hindi), Semrush finds queries Moz simply doesn’t have data for.

Here’s what that means in practice. I ran the same seed keyword, “content marketing” , through both tools on the same day.

• Moz Keyword Explorer returned 1,847 related keywords.
• Semrush Keyword Magic Tool returned 18,412 related keywords.

Same seed. Same market. Ten times the coverage on Semrush. For US-market, head-term research, Moz’s clustering and “Priority” score (a single number blending volume, difficulty, and CTR) is actually more useful than Semrush’s raw list. But when you need breadth, Semrush wins.

Keyword difficulty scores differ. Moz’s difficulty runs 0-100 based on a DA-weighted calculation. Semrush’s runs 0-100 too, but weighs backlinks more heavily. On the same 50 keywords, the correlation between the two scores is about 0.7. Close, but not identical. Don’t port numbers between tools.

Backlink data: Semrush caught up, then passed

Semrush’s backlink index surpassed Moz’s Link Explorer in both size and freshness around 2023. Semrush now claims 43 trillion backlinks crawled. Moz’s index is closer to 40 trillion but refreshes less frequently.

More important than raw size: toxic link detection. Semrush’s Backlink Audit flags spammy links with a Toxic Score, groups them by pattern, and generates a disavow file directly. Moz’s equivalent, Link Explorer, shows Spam Score per linking domain but doesn’t batch toxic links or auto-generate disavow files. For site cleanup after a bad campaign, Semrush saves 3-5 hours of manual work per audit.

Domain Authority (DA), Moz’s proprietary score, remains the most widely recognized metric in the industry. Semrush’s Authority Score tracks similar signals but isn’t cited in outreach emails the way DA still is. If you’re pitching guest posts or negotiating link placements, DA is the lingua franca. Semrush’s Authority Score is better data, but Moz’s DA is better for conversations.

Site audit depth

Semrush Site Audit checks 140+ technical SEO issues across crawlability, HTTPS, internationalization, performance, and structured data. Moz’s Site Crawl checks roughly 40 issues.

The practical difference: Semrush catches schema markup errors, hreflang issues, and AMP problems that Moz skips entirely. For multilingual or international sites, Moz’s audit will miss half of what matters. For English-language US-focused sites, Moz covers the essentials.

Crawl frequency: Moz recrawls weekly by default on Standard plan. Semrush recrawls weekly on Pro, daily on Business. If you’re shipping changes and need fast verification, Semrush’s on-demand crawl is easier to trigger.

Rank tracking: close to a tie

Both track daily rankings across desktop, mobile, and local. Both support competitor tracking. Both export to CSV, Looker Studio, and Google Sheets.

Semrush tracks 500-5,000 keywords depending on plan. Moz tracks 300-3,000. Per dollar, Moz is slightly better at the Standard tier. Above 1,000 tracked keywords, Semrush’s Position Tracking has better filters (by device, intent, SERP feature) and cleaner visualization of feature snippets, People Also Ask, and local pack wins.

Accuracy: I’ve compared both against 20 keywords I can see in incognito Google over 90 days. Both were within 1-2 positions of observed rankings 95 percent of the time. Close enough that rank accuracy shouldn’t decide the purchase.

User experience and learning curve

Moz Pro is the easier tool. Period. You can set up a campaign, run keyword research, and pull a ranking report in under 30 minutes. The interface is opinionated about what’s important, which helps beginners focus.

Semrush has 40+ tools inside one platform. The left sidebar alone has 15+ primary categories. For a new user, Semrush feels overwhelming for the first two weeks. After that, the depth becomes the value. But many solo operators never get past those two weeks.

Moz’s Keyword Suggestions tab groups terms by theme automatically. Semrush’s Keyword Magic Tool requires manual filtering to get equivalent clustering. If you’re building topic clusters, Moz saves time up front. If you’re doing competitive research at scale, Semrush’s advanced filters win.

Feature-by-feature comparison

Tallied up: Semrush wins on depth, breadth, and agency-scale features. Moz wins on price, UX, and the authority metric outreach still uses.

Who should pick Semrush

Pick Semrush if you run an agency, manage multiple client domains, need PPC research alongside SEO, do competitive intelligence regularly, build content briefs at scale, or work on multilingual sites. The Business plan at $499.95 per month is genuinely cheaper than buying Moz Pro plus Moz Local plus a PPC research tool plus a content brief tool separately.

Pick Semrush if you want one platform for SEO, PPC, content, social, and PR. The all-in-one approach has a real cost (complexity) and a real benefit (fewer tools to manage). For teams of 3+, that tradeoff usually favors Semrush.

Who should pick Moz Pro

Pick Moz Pro if you’re running one or two sites, want Domain Authority as your reference metric, prefer a tool that opens fast and shows you the right thing, or have a budget ceiling around $100-$200 per month. Moz’s 30-day free trial is genuinely useful. You can build a working SEO rhythm before deciding.

Pick Moz Pro if you’re an in-house SEO at a small brand and your CEO wants simple reports. Moz’s dashboards explain themselves. Semrush’s dashboards require a 15-minute walkthrough every time.

Reporting and integrations

Semrush’s reporting builder is stronger. You can schedule white-label PDFs with your logo, client colors, and custom section ordering. Moz Pro generates PDFs too, but the white-label option is limited to the Premium tier. For agency work, that difference alone can justify Semrush’s premium.

Semrush integrates natively with Google Data Studio (now Looker Studio), Google Analytics 4, Google Search Console, and Google My Business. Moz Pro integrates with GSC and GA4 but doesn’t push as many metrics through the connector. For building a multi-source dashboard, Semrush’s deeper API and connector coverage saves engineering time.

API access: Moz’s API is cleaner and cheaper, but limited to metrics from Moz’s ecosystem. Semrush’s API is sprawling but rate-limited, and the pricing jumps quickly once you pass the included credits on Business plans. For anything above casual API use, budget $200-$500 monthly in additional API credits on Semrush.

Use cases Moz handles better than Semrush

There are specific workflows where Moz is the cleaner tool, even with a smaller dataset.

DA-based prospect qualification. If you’re pitching guest posts or evaluating link sellers, Moz’s DA is the score publishers advertise. Semrush’s Authority Score is a better predictor, but you’ll spend half your outreach explaining what it means.

Quick campaign setup for client demos. Moz campaigns spin up in 5 minutes. You can walk a client through “here’s your ranking report” during a sales call without fumbling through 40 tools.

Keyword clustering for topic maps. Moz’s Keyword Suggestions groups related terms automatically. Semrush requires manual clustering through the Keyword Manager. For building topic clusters on a content calendar, Moz saves 2-3 hours per research sprint.

MozBar for in-SERP analysis. The free Chrome extension shows DA, PA, and link metrics directly in Google search results. Semrush’s extension exists but is heavier and slower. For quick competitive scans while browsing, MozBar is the better daily driver.

Use cases Semrush handles better than Moz

The list tilts longer in Semrush’s favor, which is why Semrush is the larger company by revenue.

Competitor content gap analysis. Semrush’s Keyword Gap tool compares up to 5 domains at once and exports missing keywords ranked by opportunity. Moz’s equivalent, Keyword Gap, covers 2 domains and lacks the opportunity scoring.

PPC campaign research. Competitor ad copy, ad history, Google Ads spend estimates, and landing page tracking. None of this exists in Moz.

Content brief generation. Semrush’s SEO Writing Assistant scores drafts against top-ranking pages for readability, keyword usage, and tone. ContentShake AI drafts articles from keywords. Moz has nothing equivalent.

Position tracking with SERP features. Semrush flags when you win a featured snippet, lose a People Also Ask spot, or enter the Local Pack. Moz tracks position but less granularly on SERP feature changes.

Multi-domain agency management. Semrush’s Projects feature handles 5-40 domains cleanly with per-client reporting. Moz’s campaigns cap earlier and don’t scale as cleanly for large agencies.

What about Ahrefs?

Both Moz Pro and Semrush compete with Ahrefs. If backlink analysis is your primary need, Ahrefs still has the most comprehensive backlink index and the cleanest competitor research workflow. For a head-to-head between Moz and Ahrefs, see Moz Pro vs Ahrefs. For a three-way view, Semrush vs Ahrefs vs Moz breaks down where each one wins.

Short version: Ahrefs is best for backlinks and competitor content gap analysis. Semrush is best for all-in-one marketing. Moz is best for UX and DA-based workflows. All three are legitimate, mature tools. None is objectively bad.

The honest recommendation

If I had to pick one tool for a brand-new SEO career, I’d pick Moz Pro for the first six months and switch to Semrush around month seven. Moz teaches you the fundamentals without overwhelming you. Semrush gives you depth once you know what depth to ask for.

If I had to pick one tool for an agency, it’s Semrush. The agency workflows (client reporting, white-label PDFs, multi-domain tracking) are better-built. Moz doesn’t pretend to serve agencies the same way.

If I had to pick one tool for a bootstrapped solo SaaS founder with no SEO background, it’s Moz Pro Standard at $99. You won’t outgrow it until you cross 5,000 monthly organic visits. By then, you’ll know whether you need Semrush’s depth or Ahrefs’ backlink data. That’s a better decision to make with six months of real SEO work behind you.

Most people overbuy SEO tools. They pick Semrush Business at $499.95 per month because it has the most features, then use 20 percent of it. A smaller tool you actually use beats a bigger tool you don’t.
