SpyFu vs Moz Pro: Data, Pricing, and Verdict for 2026

Data Depth and Database Size

The two tools index different things at different scales, and the headline numbers are misleading if you don’t understand what each tool actually crawls.

SpyFu’s keyword database is heavily skewed toward U.S. desktop and mobile data, with thinner coverage of UK, Canada, Australia, and Western Europe. The database brags 7 billion keywords, but the unique value is the 13+ year historical archive. SpyFu can show you exactly which keywords a competitor was bidding on in March 2017, what their estimated ad budget was, and which of their organic positions decayed in 2021. Nobody else offers that level of historical PPC data. If your job involves competitor PPC teardowns, you’re buying SpyFu for the time machine, not the live database.

Moz Pro’s keyword database is smaller in raw count but broader in country coverage. The 1.7 billion keyword figure spans 170+ countries, which makes Moz the better tool for international SEO research. The bigger asset on Moz’s side is Link Explorer’s link index, sitting at roughly 40 trillion links indexed in 2026. That’s still smaller than Ahrefs (60T+) but vastly larger than SpyFu’s link offering, which is barely a feature.

Keyword Research Tools Compared

For day-to-day keyword research, the two tools approach the workflow from opposite ends.

SpyFu’s keyword research starts with a competitor. Type a domain, get back a list of every keyword that domain ranks for organically and bids on for ads. Filter by position, volume, difficulty, or intent. The killer feature is the “Kombat” view that shows keyword overlap between three domains at once. For B2B SaaS competitor research, this is the fastest way I’ve found to map an entire category’s keyword universe in 20 minutes.

Moz Pro’s keyword research starts with a topic. The Keyword Explorer surfaces volume, difficulty, organic CTR, and Priority Score (Moz’s blended composite metric) for any seed term. The SERP analysis pulls live competitor pages for the query and highlights the lowest-difficulty positions to target. Moz’s keyword data tends to under-report search volume by 15 to 25 percent compared to Ahrefs and Google Keyword Planner, but the difficulty scoring is the most accurate I’ve tested, especially in the 20 to 40 difficulty range where most ranking opportunities live.

Backlink Tools Compared

This is where the gap is widest. Moz wins outright. SpyFu’s backlink offering is a token feature added to the Pro tier so the marketing page can claim “backlink data.” It’s not the tool’s job to do this well.

Moz Link Explorer indexes roughly 40 trillion links, refreshes weekly, and surfaces metrics that have been the SEO industry’s shared vocabulary for over a decade: Domain Authority, Page Authority, Spam Score, and the link distribution graph. The data isn’t as fresh as Ahrefs (which crawls in near real time) and the index is smaller, but Moz’s link metrics are still the most widely cited across the SEO industry. If you’re pitching outreach prospects, the Domain Authority number Moz gives you is the language the recipient already speaks. SpyFu’s link metrics aren’t, and using them in outreach signals “I bought the wrong tool.”

For deeper backlink research the broader landscape covered in my best link building tools comparison includes Ahrefs and Majestic, both of which beat Moz on link index depth but not on the cultural standardisation of the DA metric.

Rank Tracking

Rank tracking is one of the few areas where SpyFu surprises on the upside. The Team tier includes up to 15,000 weekly tracked keywords, versus Moz Premium’s 4,500. For agencies running rank tracking across 30+ client domains, SpyFu’s tracking volume to price ratio is the best in the category.

Two caveats. SpyFu’s rank tracker updates weekly by default, while Moz Pro updates daily on the Premium tier. Daily updates matter more if you’re managing campaigns where a 24-hour ranking shift triggers tactical decisions. Second, SpyFu’s local rank tracking is functional but not deep. Moz Pro’s local rank tracking integrates with Moz Local, which gives you a unified view of multi-location SEO that SpyFu can’t match. For local SEO agencies, Moz wins this category outright despite the lower tracking volume.

Competitor Analysis

Competitor analysis is SpyFu’s home turf and the single strongest reason to pay for it. The depth and freshness of competitor data is meaningfully better than Moz, and on PPC competitor data SpyFu is uncontested.

• SpyFu Kombat: three-way domain overlap analysis. Drop in your domain plus two competitors, get every keyword each one ranks or bids for, and the gap analysis surfaces the keywords your competitors own that you don’t. This single feature is the reason most agency users keep their SpyFu subscription.
• SpyFu PPC research: shows you the exact ad copy your competitors have run for the past 13 years, ranked by estimated spend and click volume. You can identify the headlines and offers that earned the most clicks for any major competitor. Moz has nothing comparable.
• Moz True Competitor: surfaces domains that overlap with yours on rankings, weighted by relevance. Cleaner UI than SpyFu’s competitor view, but the data depth is shallower and there’s no historical or PPC layer.

If competitor and PPC research is more than 20 percent of your weekly SEO work, SpyFu is the obvious pick. If competitor research is a once-a-quarter exercise, Moz’s lighter offering is sufficient. For a deeper teardown of the SEO competitor analysis workflow regardless of tool, the competitor analysis framework walks through the methodology.

Content and On-Page Tools

Moz wins this category cleanly because SpyFu doesn’t really play in it. Moz Pro’s Content Suggestions feature analyses your existing pages against the top-ranking SERP results and recommends additions: missing topics, related keywords, content gaps, and structural improvements. The recommendations aren’t as aggressive as Clearscope or Surfer SEO, but they’re built into a tool you’re paying for anyway, which makes them effectively free if you already have Moz Pro.

Moz’s On-Page Grader scores any URL against a target keyword and flags missing optimization elements. It’s basic compared to Surfer or PageOptimizer Pro, but it’s adequate for the 80 percent case and surfaces the obvious issues that most pages still ship with. SpyFu has none of this. If content optimization is part of your job, this category alone makes Moz the right pick over SpyFu.

Site Audit

Moz Pro includes a full crawl-based site audit that reports on technical SEO issues: broken links, redirect chains, duplicate content, missing meta data, slow pages, and crawl errors. The audit runs weekly and emails a summary report. Coverage is solid for the typical mid-size content site or SaaS marketing site.

SpyFu has no site audit. None. If you need a technical SEO audit, you’d have to add Screaming Frog ($259/year) or Sitebulb ($203/year) on top of your SpyFu subscription, which closes the price gap between the two tools meaningfully. Moz Pro at $99/month with built-in audit beats SpyFu Basic at $39 plus Screaming Frog at $22/month equivalent.

2026 Pricing Compared

SpyFu is meaningfully cheaper at every tier. The annual discount is also more aggressive at SpyFu, which means a committed SpyFu Pro subscription costs roughly $474/year, while Moz Standard runs about $948/year. If price is the deciding factor and you don’t need site audit or content tools, SpyFu wins on cost.

Accuracy Benchmarks

I ran an accuracy test across 6 client domains in early 2026, comparing both tools’ reported organic traffic and keyword counts to actual Google Search Console data over a 90-day window.

• Organic traffic estimate: SpyFu over-reported by an average of 38 percent. Moz over-reported by 22 percent. Both tools systematically overestimate traffic, which is normal for any third-party tool that doesn’t have direct access to Search Console.
• Keyword count (ranking): SpyFu reported on average 12 percent more ranked keywords than GSC, Moz 18 percent fewer. SpyFu picked up long-tail terms with low impressions that Moz missed, while Moz was more conservative in counting positions below 50.
• Top 10 ranking accuracy: Moz 94 percent agreement with GSC, SpyFu 89 percent. Both are solid for the top 10 segment that matters most.
• Difficulty score correlation with actual ranking time: Moz’s Keyword Difficulty correlated 0.71 with weeks-to-rank, SpyFu’s difficulty correlated 0.58. Moz’s difficulty scoring is meaningfully more useful for prioritization.

Reporting and Dashboards

Reporting is the unsexy comparison most vs articles skip, and it’s the one that bites agencies the hardest at scale. Moz Pro’s reporting is more polished and white-label friendly. You can generate branded PDF reports for clients with custom logos, intro paragraphs, and a defensible Domain Authority graph that clients already understand from years of industry reporting. The scheduling system delivers reports weekly or monthly, and the integration with Looker Studio is solid for agencies that prefer to roll up multiple client accounts into a single dashboard.

SpyFu’s reporting is functional but markedly weaker at the agency-presentation layer. The default exports are CSV and PDF, the white-label options are limited, and the visualizations are dated. For an in-house team that doesn’t need client-facing reports, SpyFu’s data is fine to consume directly. For an agency presenting to clients, Moz’s report polish saves an hour of manual cleanup per client per month, which is real money once you scale past 5 retainers.

API Access and Integrations

Both tools expose APIs. Moz Pro’s API is the better-documented and more widely integrated of the two: native connectors exist for Google Sheets, Looker Studio, Power BI, Zapier, and most major SEO automation platforms. The Mozscape API powers a meaningful chunk of third-party SEO tools that surface Domain Authority as a ranking signal, which is part of why DA is so culturally embedded.

SpyFu’s API is functional but less widely integrated. If you’re building a custom reporting pipeline or feeding SEO data into a CRM enrichment workflow, Moz wins on integration breadth. The exception is competitor PPC data, which SpyFu’s API exposes uniquely. If your custom workflow needs historical paid search data, SpyFu is the only viable source.

Who Each Tool Is Built For

SpyFu is built for paid media buyers, agencies running competitor PPC teardowns, and SEOs whose primary workflow is competitive intelligence. The historical PPC archive and the Kombat overlap view are unique features that justify the subscription if you use them weekly. If you don’t, you’re paying for a Ferrari to drive to the corner shop.

Moz Pro is built for organic SEOs working on content optimization, on-page SEO, link building, and technical audit. It’s the SEO industry’s default reference tool for Domain Authority and link metrics, and it’s the right pick if your job is to ship better-optimised content rather than to dissect competitors. Local SEO agencies should also default to Moz because Moz Local integrates cleanly with Moz Pro.

Onboarding and Learning Curve

Both tools are reasonably easy to learn but optimised for different mental models. Moz Pro feels like an SEO textbook turned into software: every report ties back to a familiar metric (Domain Authority, Page Authority, Keyword Difficulty, Spam Score), and the UI walks new users through suggestions and next steps. A new in-house SEO can be productive in Moz Pro within a single afternoon.

SpyFu has a sharper learning curve because the interface is busier and the metrics (SEO Strength, Ad Strength, Kombat overlap scores) are SpyFu-specific rather than industry-standard. The first time you run a Kombat report, the data dump is overwhelming. Once you’ve used the tool for two weeks, the workflow clicks, but the onboarding is rougher. For solo founders or junior SEOs, Moz’s gentler ramp is a real advantage. For experienced practitioners, the SpyFu learning curve is a one-time cost worth paying for the unique competitor data.

My Opinionated Verdict

If forced to pick one, I’d take Moz Pro for 70 percent of SEO use cases and SpyFu for the other 30 percent. The split breaks down clearly:

• Pick Moz Pro if: you spend most of your week on content optimization, on-page SEO, link building, technical audit, or local SEO. The site audit, content suggestions, and link explorer alone justify the higher price.
• Pick SpyFu if: PPC competitor research, ad copy teardowns, and historical paid search data are core to your workflow. The 13-year archive and Kombat view are uncontested in the market.
• Pick neither if: you have budget for Ahrefs ($129/month) or Semrush ($139/month). Both Ahrefs and Semrush beat SpyFu and Moz on raw data depth, link index, and feature breadth. The only reason to pick SpyFu or Moz over them is price or the specific niche features (SpyFu’s PPC archive, Moz’s DA metric).

The honest answer most SEOs don’t want to hear: in 2026, SpyFu and Moz are both second-tier tools relative to Ahrefs and Semrush on data depth. They’re worth paying for only if their specific niche features (SpyFu’s PPC archive, Moz’s DA metric and content suggestions) match your workflow, or if their cheaper price is the deciding factor. If you can afford Ahrefs or Semrush and your workflow is general SEO, you’re probably better off there.

Frequently Asked Questions

Bottom Line

SpyFu and Moz Pro solve adjacent but different problems. SpyFu is the better competitor and PPC research tool. Moz Pro is the better organic SEO and content optimization tool. Neither beats Ahrefs or Semrush on raw data depth, but both are meaningfully cheaper, and their specific niche features make them defensible for the right use case. Pick the one that matches the dominant workflow in your week, run it for 60 to 90 days, and switch if it doesn’t earn its subscription back. The wrong tool for your job is more expensive than the right tool at any price.
