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

Ahrefs wins on backlink data depth, keyword index size, and site audits on JavaScript-heavy sites. 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.

Data points below come from each tool’s own published data pages and pricing pages, checked in October 2026.

The short verdict

Factor	Winner	Margin
Backlink index size	Ahrefs	Large (fresher live index, updated every 15-30 minutes)
Keyword database	Ahrefs	Large (Ahrefs 28.7B vs Moz 1.25B)
Rank tracking limits	Ahrefs	Small (750 vs 300 keywords on the entry suites)
Site audit depth	Ahrefs	Medium
UI/UX for beginners	Moz	Medium
Entry-level pricing	Moz	Small ($99 Moz Standard vs $129 Ahrefs Lite)
Higher-tier pricing	Moz	Significant
Data freshness	Ahrefs	Medium
Domain Authority as shared metric	Moz	Industry standard
Customer support	Moz	Small

Backlink data: the single biggest gap

This is where the two tools diverge most.

Ahrefs backlink index (as of October 2026):

• 35 trillion external backlink records in its history
• About 5 million pages crawled every minute
• Updates every 15-30 minutes for newly discovered links
• Historical data back to 2013 (select domains)

Moz backlink index:

• Over 40 trillion links in Link Explorer (Moz’s own count, not directly comparable to Ahrefs’ live index)
• Crawl rate not publicly disclosed but significantly smaller than Ahrefs
• No published refresh interval for the live index
• Link data is less granular (no timestamp per discovery for most links)

When you need every link pointing at a site, index freshness decides what you see. Ahrefs refreshes its live index every 15-30 minutes, so newly discovered links can show up sooner than they do in Moz, which doesn’t publish a comparable refresh interval. For outreach, disavow cleanup, and competitor analysis, that gap matters.

Moz’s advantage: Domain Authority. Domain Authority is Moz’s own metric, 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 about 23 times larger than Moz’s.

Ahrefs: 28.7 billion keywords across 217 locations, updated monthly with new query discovery.

Moz: 1.25 billion+ keywords primarily focused on major English-speaking markets plus top EU countries.

The practical difference:

• Long-tail keywords: the larger index returns far more 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 most 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 often report different search volumes. Neither is “correct”: both estimate based on clickstream and search data. If you run Google Ads, check both against Keyword Planner data from your own campaigns before you trust either.

Rank tracking

Both tools update tracked rankings weekly. The differences are in features and limits.

Ahrefs Rank Tracker:

• Updates tracked keywords weekly on every plan
• 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 tracked keywords weekly
• 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

Neither tool offers daily rank updates, so if daily movement matters, Semrush is the one to look at. For weekly or monthly reporting, both trackers do the job, and Ahrefs tracks more keywords on its entry plan.

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:

• 100,000 to 1.5 million crawl credits a month, depending on plan
• Scans for 170+ SEO issues 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):

• 400,000 to 5 million pages crawled a month, depending on plan
• 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, and the gap widens as you scale. Moz Pro starts at $49/month for Starter and $99/month for Standard; Ahrefs starts at $29/month for Starter and $129/month for Lite.

Tier	Moz Pro	Ahrefs	Winner
Core	Standard (300 tracked keywords, 1 user)	Lite (750 tracked keywords, 1 user)	Moz on price, Ahrefs on keywords
Mid	Medium (1,500 keywords, 2 users)	Standard (2,000 keywords, 1 user)	Moz (cheaper, extra seat)
Upper	Large (3,000 keywords, 3 users)	Advanced (5,000 keywords, 1 user)	Depends on seats vs keywords
Enterprise	Custom quote	Enterprise, annual commitment	Ask both
Extra users	1 to 3 included by plan	Paid add-on per user	Moz
API access	Separate Moz API plans	API and MCP access from Lite up	Ahrefs

Annual billing: Moz saves 20% and Ahrefs up to 17%. Free trial: Moz offers a 7-day trial of its Medium plan; Ahrefs doesn’t run trials, but Ahrefs Free gives site owners limited Site Explorer and Site Audit access.

The real pricing gap: seats. Moz Large is $299/month with 3 users included; Ahrefs Advanced is $449/month with 1 user, and every extra Ahrefs seat is a paid add-on. For agencies with several team members, Moz is the cheaper option. But you pay with smaller data depth and fewer tracked keywords per plan.

Where each tool has real gaps

Ahrefs gaps:

• Limited on-page content scoring (Surfer, Clearscope do this better)
• No white-label reporting built-in (agencies need third-party tools)
• Local SEO is limited to GBP Monitor, still in beta (Yext or BrightLocal go deeper)

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
• 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 work with JavaScript-heavy sites
• Your budget supports $129+/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 of roughly $230-$430/month is acceptable

A common agency setup runs both: Ahrefs for analysis, Moz for client-facing DA reports. Neither tool is a complete substitute for the other.

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. Ahrefs’ AI Content Helper and Moz’s AI Content Briefs are newer additions with tight quotas on lower plans. Surfer, Clearscope, Frase, and MarketMuse still go deeper. You’ll want one of those in addition.

AI SEO / GEO. Both now track AI visibility: Ahrefs through Brand Radar and tracked AI prompts, Moz through AI Visibility Dashboards that follow GPT, Gemini, Google AI Mode, and Perplexity. Prompt quotas are small on the entry plans (5 tracked prompts on Ahrefs Lite, 150 on Moz Standard), so heavy GEO work still means a higher tier or a dedicated tool.

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 ($49/month) or Standard ($99/month) covers the core workflow for one site.

If you’re running an agency: Both. Ahrefs for the work, Moz for DA benchmarks and reporting. Total cost of roughly $230-$430/month is about 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. Start Moz Pro’s 7-day free trial (Medium plan). Use it on real work, not a demo project.
2. Use Ahrefs Free on your own site, or pay for one month of Lite. 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 market 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.
