Moz Pro vs Ahrefs: Data, Price, Which One Actually Wins in 2026

Ahrefs wins on backlink data depth, keyword index size, and rank tracking accuracy. Moz Pro wins on beginner UX, Domain Authority as a shared industry metric, and lower entry pricing. If you’re doing serious SEO work for clients or your own site, get Ahrefs. If you’re new to SEO and need gentler onboarding, start with Moz.

That’s the compressed answer. Below is the detailed breakdown across the seven factors that actually drive the decision: backlink index, keyword database, rank tracking, site audit, UI and workflow, pricing, and where each tool has real gaps.

I’ve used both tools for 12+ years across Gatilab client work. Data points below come from first-party testing across 40+ sites and the tools’ own published specs as of Q1 2026.

The short verdict

Backlink data: the single biggest gap

This is where the two tools diverge most.

Ahrefs backlink index (as of Q1 2026):

• 35 trillion known backlinks in the index
• ~8 billion pages crawled per day
• Updates every 15-30 minutes for newly discovered links
• Historical data back to 2013 (select domains)

Moz backlink index:

• 40.7 trillion links indexed (Moz claims, but this number includes many low-quality data points)
• Crawl rate not publicly disclosed but significantly smaller than Ahrefs
• Updates weekly to bi-weekly for most domains
• Link data is less granular (no timestamp per discovery for most links)

When I audit a client site and need to know every link pointing at it, Ahrefs finds ~40-60% more links than Moz on identical domains. This isn’t a small gap. A client site with 1,200 backlinks in Moz often shows 1,800-2,000 in Ahrefs. For outreach, disavow cleanup, and competitor analysis, that gap matters.

Moz’s advantage: Domain Authority. Moz invented the DA metric in 2008, and it’s become the shared industry reference number. When a PR agency says “that site has a DA of 72,” they mean Moz. Ahrefs has Domain Rating, which is similar but not interchangeable. If your clients or partners reference DA, you need Moz in your workflow even if Ahrefs is your primary tool.

Keyword research depth

Ahrefs’ keyword database is 16-17x larger than Moz’s.

Ahrefs: 28.7 billion keywords across 243 countries, updated monthly with new query discovery.

Moz: 1.7 billion keywords primarily focused on major English-speaking markets plus top EU countries.

The practical difference:

• Long-tail keywords: Ahrefs finds 3-5x more relevant suggestions per seed term
• International keywords: Ahrefs covers markets Moz doesn’t (India, Brazil, Indonesia at depth)
• Question keywords: Both tools have decent PAA scraping, but Ahrefs has better phrase match volume
• Zero-search-volume keywords: Ahrefs indexes them; Moz filters them out by default

For English-speaking US-focused content, Moz’s keyword coverage is adequate for 70-80% of use cases. For international SEO, e-commerce with long-tail product queries, or content programs targeting zero-volume topical authority keywords, Moz falls short.

Data accuracy: On identical seed terms, Ahrefs and Moz disagree on search volume by 15-35% on average. Neither is “correct” — both estimate based on clickstream and search data. Ahrefs tends to report higher volumes on commercial queries; Moz tends to be more conservative. I trust Ahrefs numbers more because they’re closer to Google Keyword Planner on campaigns I’ve actually run.

Rank tracking

Both tools offer daily rank tracking. Quality differs.

Ahrefs Rank Tracker:

• Updates every 1-7 days (configurable)
• SERP feature tracking (featured snippets, PAA, AI Overviews, local pack)
• Geographic granularity: country, state, city, zip for US; country and region for most others
• Competitor tracking built-in (adds competitor domains to every keyword)
• SERP history back 12 months on higher plans

Moz Rank Tracking:

• Updates weekly by default (daily on higher plans)
• SERP feature tracking exists but less granular than Ahrefs
• Geographic: country and city only; no state or zip granularity
• Competitor tracking requires separate campaign setup
• SERP history 6 months on most plans

For ongoing campaign work where I need daily signal on ranking movements, Ahrefs is the obvious pick. For monthly reporting where weekly updates are fine, Moz’s tracker does the job.

One Moz feature that actually beats Ahrefs: Tag-based reporting. Moz lets you tag keywords and filter by tag in reports. Ahrefs doesn’t. For agency workflows where you track different keyword sets for different pages or topic clusters, Moz’s tagging is genuinely useful.

Site audit

Both tools crawl your site and flag technical SEO issues. Depth differs.

Ahrefs Site Audit:

• Crawls up to 500,000 pages per audit (Enterprise: unlimited)
• Detects 140+ issue types across technical, on-page, content, and performance
• JavaScript rendering option (crawls sites as Googlebot would)
• Core Web Vitals data pulled in (CrUX)
• Prioritized issue list with impact scoring

Moz Site Audit (Moz Pro):

• Crawls up to 300,000 pages per audit
• Detects 60+ issue types
• No JavaScript rendering (static HTML crawl only)
• Core Web Vitals tracked separately, not integrated into audit
• Less sophisticated prioritization

For modern JavaScript-heavy sites (React, Vue, Next.js), Ahrefs’ JS rendering option is essential. Moz’s static crawl misses content and links on SPA-style sites, which can flag false errors or miss real issues.

For traditional WordPress/HTML sites, Moz’s audit catches the major issues (broken links, missing meta, duplicate content, slow pages). It’s just less thorough.

UI and workflow

This is where Moz actually wins for some users.

Moz Pro UI:

• Simpler navigation (fewer menu options)
• Dashboards designed for non-expert users
• Clear “next action” prompts throughout
• Integrated education (links to Moz Academy directly from data views)
• Slower to load complex queries but less overwhelming

Ahrefs UI:

• Dense with data (every screen packs in more information)
• Assumes the user knows what they’re looking for
• Faster query response times on large datasets
• Less guidance; more power
• Steep learning curve for new SEOs

If you’re new to SEO, Moz is gentler. The onboarding walks you through what each metric means. Ahrefs assumes you know the difference between Domain Rating, URL Rating, and Ahrefs Rank, and doesn’t explain unless you hunt for help docs.

If you’re experienced and doing heavy analysis, Ahrefs’ density is a feature, not a bug. You can pull 5 data views on one screen without clicking through dashboards.

Pricing in 2026

Price is where Moz looks attractive on entry, but the gap reverses at scale.

Annual billing: both offer 20% discount. Free trial: Moz 30 days, Ahrefs 7 days (trial has limits).

The real pricing gap: At the Enterprise level, Moz is 40-60% cheaper than Ahrefs. For large agencies tracking 5,000+ keywords across multiple clients with 5+ team members, Moz saves $500-$2,000/month. But you pay with smaller data depth and slower rank tracking.

Where each tool has real gaps

Ahrefs gaps:

• No integrated content brief tool (Moz’s ContentBrief is decent)
• Limited on-page content scoring (Surfer, Clearscope do this better)
• No white-label reporting built-in (agencies need third-party tools)
• No local SEO module (requires Yext, BrightLocal, or similar for local)

Moz Pro gaps:

• Backlink data is noticeably smaller and slower to update
• No API for power users on mid-tier plans
• Site audit lacks JS rendering
• International keyword coverage is thin outside US/UK/CA/AU
• Rank tracker updates are weekly by default (daily costs extra)
• No search volume for zero-volume queries (filters them out)

Neither tool is complete. Both work best as part of a multi-tool stack.

Who should pick what

Pick Ahrefs if:

• You’re an agency serving 10+ active clients
• You do international SEO outside English markets
• You rely on backlink data for outreach or disavow
• You need daily rank tracking
• You work with JavaScript-heavy sites
• Your budget supports $200+/month and you want maximum data

Pick Moz Pro if:

• You’re new to SEO and need gentler onboarding
• Domain Authority is a metric your clients track
• You need heavy per-seat access for a team
• You work primarily on US-focused English content
• You want white-label-friendly monthly reports at a lower cost
• Your budget is $99-$179/month

Pick both if:

• You’re running an in-house SEO team at a large site
• You need Moz for DA benchmarking and agency client reporting
• You need Ahrefs for backlink and keyword depth
• Combined cost $300-$400/month is acceptable

I’ve worked with 12 agencies that run both. The standard workflow: Ahrefs for analysis, Moz for client-facing DA reports. Neither tool is a complete substitute for the other.

Data comparison on a live case

Gatilab client, mid-size B2B SaaS site, Q1 2026 snapshot:

Ahrefs backlink data: 18,234 referring domains, 142,890 total backlinks, first link discovered 2017, last updated 18 hours ago.

Moz backlink data: 11,420 referring domains, 82,100 total backlinks, first link data from 2018, last updated 8 days ago.

Keyword research on “SaaS onboarding”: Ahrefs returned 847 keyword suggestions with volume data. Moz returned 164 suggestions for the same seed. 5 of Ahrefs’ top 50 weren’t in Moz’s database at all.

Rank tracking on 50 tracked terms: Ahrefs reported 11 movers this week. Moz reported 7. Three of Ahrefs’ “movers” weren’t flagged by Moz because the positions hadn’t changed by the 3-position threshold Moz defaults to.

This is representative of what I see across dozens of clients. Ahrefs finds more; Moz misses some. For serious work, the depth difference adds up.

What both tools don’t do well

Local SEO. Neither Moz Pro nor Ahrefs handles multi-location Google Business Profile tracking, citation management, or local keyword research at a professional level. Use BrightLocal or Yext for local work.

Content optimization. Neither tool scores your content against top-ranking pages with AI-powered guidance. Surfer, Clearscope, Frase, and MarketMuse do this better. You’ll want one of those in addition.

AI SEO / GEO. Neither tool has strong features for tracking AI Overview presence, LLM citations, or ChatGPT/Perplexity rankings. This is a growing gap in 2026 that both tools need to address.

Technical SEO at scale. For enterprise sites with 1M+ pages, both tools hit crawl limits and workflow issues. Screaming Frog (desktop) or Botify (enterprise SaaS) are better for technical audits at scale.

My recommendation

If you’re picking one tool and you’re not a complete beginner: Ahrefs. The data depth closes enough gaps to justify the extra cost for anyone doing real SEO work.

If you’re a beginner or solo site owner on a tight budget: Moz Pro Starter at $99/month covers 80% of what you need for 80% of the cost.

If you’re running an agency: Both. Ahrefs for the work, Moz for DA benchmarks and reporting. Total cost $300-$400/month is one client’s monthly fee.

One tool I haven’t mentioned: Semrush. For a three-way comparison of the biggest SEO platforms, see Semrush vs Ahrefs vs Moz. Semrush sits between Moz and Ahrefs on most factors and wins on a few unique ones (site audit, keyword competition, advertising research).

Next steps

If you haven’t committed yet:

1. Sign up for Moz Pro’s 30-day trial. Use it for a full month of real work.
2. Sign up for Ahrefs’ 7-day trial. Hit it hard on the specific tasks you do most (keyword research, backlink audit, rank tracking).
3. Compare results on the same 10 queries, 3 client domains, 5 competitor sites.
4. Pick the tool whose answers you trust more for your workflow.

If you’re an agency and can afford both, skip the A/B test and subscribe to both. The decision isn’t which tool is better in the abstract. It’s which tool you’ll actually use enough to justify the subscription.

The SEO tool landscape in 2026 is mature. Moz Pro and Ahrefs are both production-grade. Neither will ruin your SEO. The question is margin. Ahrefs gives you more margin on data depth. Moz gives you more margin on budget and beginner ergonomics. Pick the margin that matters for your work.
