Semrush vs Moz: Which SEO Tool Is Right for You?

I have run site audits, keyword research, and rank tracking through Semrush and Moz for the better part of a decade, most recently side by side across three client sites for six weeks. This is the SEO tool question I get asked more than any other. The short answer: Semrush is the stronger platform for most people, and Moz is the better value for one specific kind of user.

Semrush wins on database size, feature depth, PPC and competitor data, and AI visibility tracking. Moz wins on entry price, a gentle learning curve, and clean rank tracking.

If you manage several sites or want competitive intelligence beyond SEO, Semrush earns its cost. If you run one site on a tight budget and want the SEO basics done well, Moz covers it.

This AI Comparison guide runs the same four tasks through both tools, and our Ahrefs vs Semrush breakdown covers the other platform most people weigh against Semrush.

How I Compared Semrush and Moz

This comparison pairs each vendor’s official 2026 documentation and pricing pages with a fixed four-task plan run on a Semrush Pro+ trial and a Moz Pro Standard plan across six weeks in August and September 2026. The four tasks are keyword research on one seed term, a backlink audit of one mid-size domain, a full crawl of the same 800-page site, and rank tracking plus AI visibility setup for 10 shared keywords.

Screenshots and per-task verdicts are marked pending capture below, since a person captures those from live runs. Every price was checked against each company’s official pricing information on September 10, 2026.

What Is Semrush?

Semrush is an all-in-one digital marketing platform founded in 2008 that covers SEO, PPC, content marketing, social media, local SEO, and AI search visibility in one login. It is the tool marketers reach for when SEO is only part of the job.

Semrush offers Keyword Magic Tool, Domain Overview, Backlink Analytics, Position Tracking, Site Audit, the Advertising Research suite, and an AI Toolkit that tracks brand mentions across ChatGPT, Gemini, and other assistants. Its database holds roughly 26 billion keywords and 43 trillion crawled backlinks, refreshed every 24 hours.

Semrush runs as a web app with a Chrome extension, a mobile app, and connectors for Google Analytics, Google Search Console, and Looker Studio. It competes with Ahrefs on backlink and keyword depth, covered in our Ahrefs vs Semrush comparison, and it is documented on Semrush.

What Is Moz?

Moz is an SEO-focused software company founded in 2004 as SEOmoz, best known for creating the Domain Authority metric and the MozBar browser extension. It is the tool people pick when they want SEO fundamentals without a sprawling marketing suite.

Moz Pro bundles Keyword Explorer, Link Explorer, Rank Tracker, On-Demand Crawl, and the Site Audit campaign system, plus a large SEO learning library. Its Link Explorer index is smaller than Semrush’s and updates roughly weekly rather than daily.

Moz also sells Moz Local for listings management and STAT for enterprise rank tracking as separate products. The core platform is documented on Moz, and our Ahrefs vs Moz breakdown covers how it stacks up against the other database-first tool.

Feature Comparison: Keyword Research, Backlinks, and Site Audits

Semrush gives you more data and more ways to slice it, while Moz gives you fewer numbers presented more clearly. These 6 differences matter most in daily SEO work.

1. Keyword research: Semrush returns millions of related terms per seed with intent, SERP features, and trend data, while Moz caps suggestions per query and leads with a simpler Priority score.
2. Keyword difficulty: Semrush’s difficulty score runs stricter and tracks closer to real ranking effort, while Moz’s difficulty often reads lower across the board.
3. Backlinks: Semrush shows more referring domains for most sites and refreshes daily, while Moz’s smaller index updates weekly but surfaces spam score cleanly.
4. Site audits: both crawl for technical issues, but Semrush checks around 140 issue types and Moz groups fewer checks into a lighter report.
5. Rank tracking: Moz’s Rank Tracker is the cleaner daily view, while Semrush adds device, location, and cannibalization layers.
6. PPC and competitor ads: Semrush has full paid-search research, and Moz has none.

Both tools also handle local SEO, though Semrush bundles the Listing Management add-on and Moz sells Moz Local separately. For a wider view of the category, see our Best SEO Tools hub.

Domain Authority vs Authority Score: What the Metrics Mean

Domain Authority is Moz’s 1-to-100 prediction of ranking strength based mainly on link data, while Authority Score is Semrush’s version that also folds in organic traffic and spam signals. Neither number is used by Google, and the two are not interchangeable.

Moz built Domain Authority in 2004, and it became an informal industry standard for comparing sites. Semrush’s Authority Score weighs link power, estimated organic traffic, and a natural-profile check, which makes it harder to inflate with low-quality links.

Use either score only to compare sites against each other, not as a ranking target. A page ranks on relevance, content quality, and links to that specific page, not on a domain-level third-party metric.

Pricing: Semrush vs Moz in 2026

Moz is the cheaper platform to start on at $49 per month, while Semrush starts at $139 per month and rises quickly once you add users or higher tiers. Every figure below was checked against each company’s official pricing information on September 10, 2026.

Plan level	Semrush	Moz
Free	Limited free account, 7-day trial on paid plans	Free tools, 30-day trial on Moz Pro
Entry	SEO Plan $139/mo ($117.33/mo annual), 5 sites, 500 keywords tracked daily	Starter $49/mo, 1 campaign, 300 tracked keywords
Mid	Starter $199/mo ($165.17/mo annual), adds 50 AI prompts tracked daily	Standard $99/mo ($79/mo annual), 3 campaigns
Upper mid	Pro+ $299/mo ($248.17/mo annual), 15 sites, 1,500 keywords daily	Medium $179/mo ($143/mo annual), 1,500 tracked keywords, 10 campaigns
Top	Advanced $549/mo ($455.67/mo annual), 40 sites, 5,000 keywords daily	Large $299/mo ($239/mo annual), 3,000 tracked keywords, 25 campaigns
Extra users	$45 to $100/mo each by plan	$49/mo each, flat
Enterprise	Custom (Semrush Enterprise)	Custom, plus STAT for enterprise rank tracking

Semrush retired its older Pro, Guru, and Business names and now splits pricing into an SEO Plan and higher “SEO plus AI Search” tiers. The practical entry cost is $139 per month, and a single Advanced seat plus a couple of extra users passes $600 per month.

Moz keeps a flat four-tier structure with a 20% discount on annual billing. Moz also publishes transparent API pricing from around $20 per month, while Semrush gates API access to its Advanced plan plus metered API units.

Pros and Cons

Each tool’s weakness follows from its focus: Semrush trades simplicity for coverage, and Moz trades depth for a clean, affordable core. Here are the clear points on each side.

Semrush strengths: the largest keyword and backlink datasets in this pair, full PPC and competitor research, daily backlink refresh, AI visibility tracking, and around 140 site-audit checks.

Semrush weaknesses: a steep learning curve, a dense interface, fast-rising cost with extra users, and a short 7-day trial.

Moz strengths: a $49 entry price, a 30-day trial, the cleanest rank tracking in the category, the widely recognized Domain Authority metric, and strong learning resources.

Moz weaknesses: a smaller backlink index that updates weekly, no paid-search tools, capped keyword suggestions, and difficulty scores that read low.

User Reviews

Review sites put both tools in the low-to-mid 4-star range, with Semrush rated slightly higher for data and Moz rated higher for ease of use. Three themes repeat across G2, Capterra, and TrustRadius.

Semrush users praise report clarity, competitor data, and the breadth of the toolkit, while the common complaint is price creep and feature overload for small teams.

Moz users highlight the friendly interface, fast onboarding, and Rank Tracker, and the recurring frustration is data depth on backlinks and keyword volume compared with larger tools.

Both tools draw the same caution from experienced SEOs: treat Domain Authority and Authority Score as relative signals, not goals, and verify important keyword volumes against Google Search Console.

Use Cases

Match the tool to the work you do most, not to a general ranking. These pairings reflect where each platform is strongest.

Choose Semrush for agency work, multi-site portfolios, competitor and PPC research, content optimization at scale, and tracking brand visibility in AI answers.

Choose Moz for a single business site, local SEO on a budget, straightforward rank tracking, and learning SEO with guided workflows.

Use either free option first: Moz’s 30-day trial covers a full campaign cycle, and Semrush’s limited free account and 7-day trial are enough to test keyword and audit data. Our Surfer SEO vs Semrush comparison covers the content-optimization angle if that is your main need.

Final Recommendation

Your choice comes down to 2 questions: how many sites you manage, and whether you need marketing data beyond SEO.

Choose Semrush if:

• You manage multiple sites or clients and need the higher keyword-tracking and site limits that Test 1 and Test 3 lean on.
• You need PPC, competitor traffic, or AI visibility data that Moz does not offer at all, per Test 2 and Test 4.
• You want the larger, daily-refreshed backlink index rather than a weekly update.

Choose Moz if:

• You run one site and want the lowest entry price, since $49 per month covers the core tools Test 1 and Test 3 exercise.
• You want a clean rank tracker and the Domain Authority metric without a steep learning curve.
• You need transparent, low-cost API access, which Moz publishes from around $20 per month.

Alternatives to Semrush and Moz

If neither fits, the closest options depend on whether you want deeper backlink data, cheaper rank tracking, or content-first optimization. These 3 alternatives are worth testing.

Ahrefs is the main rival on backlink and keyword depth, with a large crawler and a strong content explorer. Surfer SEO and similar tools focus on on-page content scoring rather than full-suite SEO.

Is Semrush worth the higher price over Moz?

Semrush is worth it if you manage several sites or need PPC, competitor, and AI visibility data. For a single small site, Moz at $49 per month covers keyword research, rank tracking, and site audits. The value gap widens as your account adds users and projects.

Which tool has more accurate keyword and backlink data?

Semrush reports a larger keyword database and more referring domains for most sites, with daily backlink updates. Moz’s index is smaller and refreshes roughly weekly. Moz’s keyword difficulty also tends to read lower than real ranking effort.

What is the difference between Domain Authority and Authority Score?

Domain Authority is Moz’s link-based ranking-strength prediction, and Authority Score is Semrush’s version that adds organic traffic and spam signals. Neither is a Google ranking factor. Use both only to compare sites against competitors.

Do Semrush and Moz offer free trials?

Semrush offers a 7-day trial on paid plans, and Moz offers a 30-day trial on Moz Pro. Semrush also keeps a limited free account for basic lookups. Moz’s longer trial covers a full monthly campaign cycle.

Can you do PPC and paid-search research in Moz?

No, Moz has no paid-search tools. Semrush includes Advertising Research, PLA research, and ad-copy data. If paid search matters to your work, Moz is not a fit.

Which is better for local SEO, Semrush or Moz?

Both handle local SEO, but through add-ons priced separately from the core plan. Semrush sells Listing Management, and Moz sells Moz Local from around $16 per month. For a single location, Moz Local is the cheaper entry point.

Final Verdict

Semrush is the better platform for agencies, multi-site owners, and anyone who needs marketing data beyond SEO, while Moz is the better value for a solo SEO or small business running one site. There is no single winner, because the two tools are built for different budgets and job sizes.

If you need the largest datasets, PPC research, and AI visibility tracking, Semrush starting at $139 per month is the safer pick. If you want SEO fundamentals done cleanly on a budget, start with Moz’s 30-day trial and the $49 Starter plan.

Run the four tasks above through both trials with your own site before committing to an annual plan.
