SpyFu vs Moz: Data Depth, Features, and Which to Choose in 2026

SpyFu beats Moz on competitor intelligence, PPC research, and ad keyword data. Moz beats SpyFu on site audit, Domain Authority as a shared metric, rank tracking, and on-page SEO tools. Most SEOs need both, but if you’re picking one, the decision comes down to whether you do paid media or organic SEO primarily.

Here’s the factor-by-factor breakdown, the data depth comparison, and my recommendation based on actual use across 20+ client accounts.

The short verdict

What each tool is built for

SpyFu and Moz don’t really compete head-to-head. They solve different problems.

SpyFu is competitor intelligence software. Its core question: “What is my competitor doing on Google, both organically and in paid ads?” The tool is built around showing you every keyword a competitor has ever ranked for, every Google Ad they’ve ever run, and historical changes in their strategy.

Moz is an SEO platform. Its core question: “How do I rank my own site on Google?” The tool is built around keyword research, backlink analysis, rank tracking, and site audits for your own properties.

This difference changes everything about when you’d pick one over the other.

Competitor keyword research

SpyFu’s strongest feature, and Moz doesn’t have an equivalent.

SpyFu competitor research:

• Type in any competitor domain
• See every organic keyword they rank for (current + historical)
• See every paid keyword they’ve ever bid on
• See every ad copy variant they’ve used
• Export all of it
• 13+ years of historical data (back to 2012 for most major domains)

Moz competitor research:

• Type in a domain under “Competitive Research”
• See top-ranking keywords (top 1,000 by volume)
• No historical PPC data
• No ad copy archive
• Limited to current snapshot

If your job involves looking at what’s working for competitors, SpyFu is 10x more useful. I’ve used it for 80+ competitive audits. The historical view is the killer feature — you can see how a competitor’s strategy evolved over years, when they launched new product lines (indicated by keyword clusters appearing), when they pulled back on SEO (keywords dropping off).

Verdict: SpyFu wins big on competitor research.

PPC and ad intelligence

Moz doesn’t do PPC research. SpyFu is a dedicated PPC intelligence tool.

SpyFu PPC features:

• Historical bid data per keyword per domain
• Ad copy for every variant the competitor has tested
• Estimated monthly PPC spend per domain
• Average CPC by keyword
• Weekly ad updates
• Kombat feature (side-by-side paid keyword overlap between 3 domains)
• Landing page archive for every ad

Moz PPC features:

• None

If you manage Google Ads campaigns or you’re researching paid media opportunities, SpyFu is the tool. Moz isn’t even in the conversation.

Verdict: SpyFu. Not close.

Organic SEO research

Moz is more useful for your own site’s organic SEO.

Moz SEO research:

• Keyword research with volume, KD, and intent
• On-page content scoring
• SERP analysis per query
• Page Authority and Domain Authority per result
• PAA and SERP feature detection
• Content brief generation (higher tiers)
• Mozbar browser extension (free)

SpyFu SEO research:

• Basic keyword research with volume and difficulty
• SERP analysis (limited depth)
• No content scoring
• No on-page optimization tools
• No browser extension equivalent to Mozbar

For doing SEO work on your own site (keyword research for new content, optimizing existing pages, tracking rankings), Moz’s toolset is broader and more actionable.

Verdict: Moz for organic SEO work on your own sites.

Backlink analysis

Both tools have backlink modules. Moz’s is larger. Neither matches Ahrefs.

Moz Link Explorer:

• ~40 trillion links indexed
• Updates weekly
• Spam score per link
• Anchor text analysis
• Top pages by link equity
• Link Intersect (find domains linking to competitors but not you)

SpyFu backlink research:

• Smaller backlink index than Moz
• Fewer tools for deep backlink analysis
• Focused more on inbound links to competitor ad landing pages

If backlinks are core to your work (outreach, disavow, link audits), Moz is better. If you’re mainly looking at competitor link strategies as a piece of larger competitive analysis, SpyFu’s data is adequate.

Verdict: Moz.

Site audit

Moz has one. SpyFu doesn’t.

Moz Site Crawl:

• Crawls up to 300,000 pages per audit
• Flags 60+ issue types
• Prioritized fix list
• Scheduled recrawls

SpyFu Site Audit:

• Not a feature

If you need to technically audit your own site, Moz is the tool. SpyFu isn’t an option.

Verdict: Moz.

Rank tracking

Both have rank trackers. Moz’s is better.

Moz Rank Tracker:

• Weekly updates default, daily on higher plans
• 200+ countries and cities
• Tag-based campaign organization
• SERP feature tracking
• Competitor position tracking

SpyFu Rank Tracker:

• Weekly updates
• US, UK, Canada, Australia primarily
• Less granular geography
• Basic competitor overlay
• No tag organization

For structured rank tracking workflows, Moz is stronger. SpyFu’s tracker exists but isn’t the reason anyone subscribes.

Verdict: Moz.

Historical data

SpyFu wins decisively here.

SpyFu historical data:

• 13+ years of SERP snapshots
• See when a domain first ranked for any keyword
• See every position change over time
• See every paid ad ever run (text and landing pages)
• Historical estimated traffic curves

Moz historical data:

• 6-24 months of rank history depending on plan
• 12-18 months of backlink history
• No historical PPC data (doesn’t track PPC)

If your work involves understanding how things changed (post-algorithm update analysis, competitor strategy pivots, recovering from a penalty), SpyFu’s time-machine is invaluable.

Verdict: SpyFu.

Pricing in 2026

SpyFu is significantly cheaper at entry.

SpyFu’s entry tier at $39/month is one of the cheapest serious SEO tools on the market. Moz’s $99/month Starter is 2.5x more expensive but includes a broader feature set.

Who should pick what

Pick SpyFu if:

• You run or manage Google Ads campaigns
• Your workflow is 60%+ competitive research
• You need historical SERP data (post-update analysis, competitor tracking over time)
• Your budget is tight and you need competitor intelligence specifically
• You’re a PPC consultant, agency, or in-house ads manager

Pick Moz if:

• You focus on organic SEO for your own sites or clients
• You need site auditing and technical SEO tools
• You rely on Domain Authority as a reportable metric
• You need broader keyword research with volume and difficulty
• You’re doing link building or disavow work

Get both if:

• You run a full-service agency handling both SEO and PPC
• Your budget supports both ($140/month combined basic)
• You need deep competitive intel plus your own site’s audit and tracking

I’ve run both at Gatilab for 6+ years. For $140/month combined you get strengths that don’t overlap. Most agencies should subscribe to both.

What neither tool does well

Local SEO. Use BrightLocal or Yext for multi-location work.

Content optimization scoring. Use Surfer, Clearscope, or Frase.

AI Overview and GEO tracking. Both tools track whether an AI Overview appears but neither accurately tells you if you’re cited.

Technical SEO at enterprise scale. Use Screaming Frog (desktop) or Botify (enterprise) for sites over 500,000 pages.

The honest recommendation

If your question is “which SEO tool should I buy as a solo marketer,” the answer is usually neither of these. You want Ahrefs or Semrush first. Both are broader, better-funded tools that cover 80% of what SpyFu and Moz do individually.

SpyFu is a specialist. If you specifically need competitor intelligence and PPC research, SpyFu earns its place. If not, you can skip it.

Moz is a generalist. It’s adequate for most SEO work but doesn’t lead in any single category anymore. The tool where Moz clearly wins is Domain Authority as a shared industry metric — if that’s what you need, Moz is the source.

For most Gatilab clients in 2026: Ahrefs for analysis + SpyFu for PPC intelligence + Moz Pro occasionally for DA reporting. That’s the typical stack for serious SEO work.

Next steps

Decide based on your primary workflow:

• Heavy competitor research or PPC: SpyFu first
• Organic SEO on your own sites: Moz Pro first
• Both: both

Use free trials. Moz has 30 days. SpyFu has a 7-day money-back guarantee (not a free trial, but equivalent). Test them on your actual work for a week each.

Don’t buy a tool because it’s popular. Buy the one whose answers help your work. Both SpyFu and Moz have real use cases in 2026, but not the same use cases.
