Semrush vs Moz

Semrush is the Swiss Army knife of digital marketing. Moz is the trusted name that built the SEO industry. But in 2026, one has clearly pulled ahead.

Last updated: 2026-02-23

Honest Tradeoffs

Every tool has tradeoffs. Here's what you're actually choosing between.

Keyword Database

Semrush

25.5B keywords across 130 countries. Updated frequently.

Moz

1.25B keywords across 170+ countries. Smaller but decent.

Semrush's keyword database is 20x larger. For long-tail keyword discovery and competitive analysis, this gap is massive.

Domain Metrics

Semrush

Authority Score — good but less widely adopted.

Moz

Domain Authority (DA) — the industry standard for link metrics.

Moz's DA is the most recognized domain metric in SEO. It's used in outreach, reporting, and valuation. This is Moz's enduring moat.

Platform Breadth

Semrush

SEO + PPC + content + social + competitive intel. Full marketing suite.

Moz

SEO only. Clean and focused.

If you need more than SEO, Semrush replaces 3-4 tools. If you only need SEO, Moz's simplicity is an asset, not a limitation.

Local SEO

Semrush

Local SEO toolkit included (listing management, map tracking).

Moz

Moz Local — dedicated local SEO product. Strong for brick-and-mortar.

Moz Local is a genuinely strong product for managing business listings across directories. For local SEO specifically, Moz competes well.

Pricing

Semrush

$139.95/mo Pro, $249/mo Guru, $499/mo Business.

Moz

$99/mo Standard, $179/mo Medium, $299/mo Large.

Moz is cheaper at every tier. But Semrush includes PPC, content, and social tools that Moz doesn't offer at any price.

Detailed Breakdown

Keyword Research

Semrush wins

Semrush's keyword database is 20x larger than Moz's. This translates to more long-tail keyword ideas, better competitive gap analysis, and more comprehensive SERP data. Moz Keyword Explorer is clean and user-friendly but simply has less data to work with. For serious keyword research, Semrush is in a different league.

Link Analysis

Semrush wins

Interesting comparison here. Moz's Link Explorer has a similar-sized index to Semrush, and Domain Authority remains the gold standard metric. But Semrush's link building tools, toxic link identification, and outreach features are more comprehensive. Moz has the metric; Semrush has the workflow.

Local SEO

Moz wins

Moz Local is genuinely excellent for managing local business listings, tracking local rankings, and monitoring reviews across directories. Semrush has local SEO tools, but Moz's dedicated product is more refined for brick-and-mortar businesses.

Learning & Community

Moz wins

Moz built the SEO education industry. Their Beginner's Guide to SEO, Whiteboard Friday, and community resources are unmatched. Semrush has good educational content too, but Moz's legacy and community are special.

Switching Costs

Already using one? Here's what it takes to switch.

Semrush → Moz

Easy — a few hours

Moz → Semrush

Easy — a few hours

Both are SaaS tools — switching is instant. Rebuild projects, tracked keywords, and saved reports. No data lock-in. You'll lose historical rank tracking data, which neither exports well.

FAQ

Is Moz still relevant in 2026? ▾
Yes, but increasingly as a niche tool. Domain Authority is still the standard metric, Moz Local is strong, and their educational content is excellent. But as an all-around SEO platform, Moz has fallen behind Semrush and Ahrefs.
Is Semrush worth the extra $40/mo over Moz? ▾
Absolutely, for most users. The 20x larger keyword database, PPC tools, content marketing features, and competitive intelligence justify the premium. The only exception is if you truly only need basic SEO at a budget price.
What about Ahrefs vs Moz? ▾
Ahrefs is also significantly ahead of Moz in backlink data, keyword research, and feature set. The real comparison in 2026 is Semrush vs Ahrefs — Moz is in a different tier.
Should I use Moz just for Domain Authority? ▾
You can check DA for free with Moz's free tools or the MozBar browser extension. You don't need a Moz Pro subscription just for DA checks.

Neither feels right?

Consider Ahrefs — If you want the best backlink data and a cleaner interface than Semrush. Ahrefs is the strongest Semrush competitor — better for pure SEO work, though it lacks PPC and social tools.
