We've used Moz Pro since 2014 and Ahrefs since 2017. The gap that opened between them in 2020 has widened, not closed. Here's the agency-level head-to-head with the specific workflows, pricing realities, and the one feature where Moz still genuinely wins.
**Ahrefs wins on data depth, link analysis, keyword research, and site audit.** Moz still wins on ease of onboarding for non-SEO users and on the brand recognition of Domain Authority outside the SEO community. For working SEO professionals running paid client work or in-house programs of any meaningful scale: Ahrefs in 2026, with very few caveats.
Ahrefs runs an in-house web crawler at the third-largest scale in the public web (after Google and Bing). Roughly 8 billion URLs crawled daily, indexing 16 trillion+ links, with a fresh crawl cycle that surfaces new backlinks within 15-60 minutes for the highest-tier domains.
Moz Link Explorer, rebuilt on the Mozscape successor index, is genuinely improved since 2022 — but it's still roughly 30-40% the size of Ahrefs's index by referring-domain count, and its discovery latency is measured in days rather than hours. For lost-link recovery and competitive link-velocity monitoring, this is a real workflow gap.
Ahrefs Keywords Explorer surfaces ~28 billion keywords across 243 countries with proprietary clickstream + SERP scraping. Moz Keyword Explorer, last meaningfully overhauled in 2020, is materially smaller — roughly 500M keywords with cleaner Google Suggest integration but thinner long-tail coverage.
For working SEO planning, Ahrefs's Parent Topic clustering, Traffic Potential metric, and SERP Overview alone are reason enough to prefer it. We have not run a content brief from Moz keyword data in roughly two years.
Ahrefs Site Audit catches more issues, has better JavaScript rendering parity with Google, and the Issues view groups problems in a way an engineering team can prioritize. Moz Pro Site Crawl is more visually digestible for non-technical readers but misses more nuanced technical problems and doesn't render JS-heavy pages as cleanly.
For agencies handing audits to engineering teams: Ahrefs. For agencies presenting to marketing executives who want a clean traffic-light visual: Moz.
**Domain Authority brand recognition.** DA remains the single most-recognized SEO metric outside the SEO industry. Journalists, executives, and procurement teams understand DA in a way they don't yet understand Ahrefs's DR. If your work involves communicating SEO outward — pitch decks, PR outreach, executive reporting — Moz still has utility purely as a credibility metric you can cite.
**MozCast and the public SEO data Moz publishes.** Moz's industry research and tracking dashboards (MozCast for SERP volatility, Local Search Ranking Factors survey, the State of SEO reports) are valuable and free. You don't need a Moz subscription to consume them, but the infrastructure that produces them is part of why Moz Pro retains its mindshare.
**The Moz Q&A community and learning content.** The Moz Academy and Whiteboard Friday archive remain the best free SEO learning resource on the web. Useful for training junior team members regardless of which tool you actually buy.
**Moz Pro Standard:** $79/mo. 1 user. 50 keywords tracked. Suitable for single-site owners. **Moz Pro Medium:** $179/mo. 2 users. 300 keywords tracked. The agency-credible tier. **Moz Pro Large:** $299/mo. 3 users. 1,500 keywords tracked. **Moz Pro Premium:** $599/mo. 5 users. 3,000 keywords tracked.
**Ahrefs Lite:** $129/mo. 1 user. 750 keyword positions tracked. Closer in shape to Moz Standard but with substantially deeper keyword + link data. **Ahrefs Standard:** $249/mo. 6 users. 2,000 keyword positions. Roughly comparable to Moz Pro Medium-Large in raw scope, but with materially better data. **Ahrefs Advanced:** $449/mo. 10 users. 5,000 keyword positions. Comparable shape to Moz Premium, half the price for similar limits.
Dollar-for-dollar in 2026, Ahrefs offers more analyst utility per dollar than Moz Pro at every tier. The exception is the under-$100/mo bracket where Moz Standard is the only credible option.
Yes — for content marketers who need keyword research and basic on-page guidance without the depth of Ahrefs or Semrush, Moz Pro Standard at $79/mo is a reasonable choice. The interface is friendlier and the learning resources are stronger. Don't expect deep competitor link analysis at this tier from any tool.
Partially. Both tools allow CSV import of keyword lists. Historical rank position data does not transfer cleanly — when you switch tools, you lose the ability to view multi-year ranking timelines unless you exported them as flat data first.
Ahrefs publishes Search Volatility (Keyword Movements) and the SEO Ranking Factors Study less frequently. SEMrush Sensor is the closer daily equivalent to MozCast in 2026.
Both tools' certifications carry equivalent weight in agency hiring (which is to say, very little — agencies hire for portfolio and case-study evidence, not certifications). Google Analytics + Search Console fluency carries more weight than either tool's cert.
Moz bills in USD globally. Same with Ahrefs. Budget for currency conversion + 2.5% foreign-transaction fees on credit cards. Both tools accept business cards without issue.
