Quick verdict
Moz wins on price and simplicity, making it a solid starting point for small businesses and SEO beginners who mainly need rank tracking, site audits, and Domain Authority checks. Semrush wins on raw capability: its keyword and backlink databases are larger and faster to refresh, and it bundles PPC, social, and content tools that agencies and larger teams actually use day to day.
What is Moz?
Moz is an SEO platform best known for popularizing Domain Authority (DA), a widely cited metric for gauging a site's ranking strength. It offers keyword research, weekly rank tracking, site audits, and a link index through Link Explorer, all wrapped in an interface built for people newer to SEO. A recently added AI Visibility beta (Medium plan and up) tracks how often a brand is mentioned in ChatGPT and Gemini responses.
What is Semrush?
Semrush is a broad SEO and digital marketing suite covering keyword research, backlink analysis, technical site audits, rank tracking, content optimization, competitor analysis, PPC research, and social media tools in one login. Its keyword and backlink databases are among the largest in the industry, which is why agencies and larger marketing teams lean on it as a single source of truth across channels.
Key differences at a glance
Data depth: Semrush indexes a larger, more frequently updated keyword and backlink database (competitive with Ahrefs), while Moz's keyword database (around 500 million) and link index update and refresh more slowly.
Price: Moz starts at $49/mo (or $39/mo annual) and tops out at $299/mo for Large. Semrush starts far higher at $139.95/mo and reaches $499.95/mo for Business, reflecting its wider feature set.
Ease of use: Moz has a cleaner, less overwhelming interface that is friendlier to SEO beginners and small business owners managing their own site. Semrush's depth comes with a steeper learning curve and a busier dashboard.
Scope: Moz focuses narrowly on core SEO: rankings, audits, links, and keywords. Semrush extends into PPC research, social media management, content marketing tools, and competitive intelligence across an entire marketing stack.

Pricing comparison
Moz Moz Pro runs four tiers: Starter at $49/mo ($39/mo billed annually), Standard at $99/mo, Medium at $179/mo, and Large at $299/mo. There is no free plan, but Moz offers a 7-day free trial plus the always-free MozBar extension and limited free DA and Link Explorer lookups. AI Visibility, which tracks brand mentions in ChatGPT and Gemini, is available starting on the Medium plan. Verified June 2026.
Semrush Semrush prices three main tiers: Pro at $139.95/mo for freelancers and small teams, Guru at $249.95/mo adding historical data and content tools, and Business at $499.95/mo for agencies needing API access and higher limits. Semrush does not offer a real free plan, only a very limited free account, and annual billing brings meaningful savings on every tier. Verified June 2026.
Moz is meaningfully cheaper at every tier and is the better fit for solo users, small businesses, and anyone on a tight SEO budget. Semrush costs roughly 3x more at the entry tier, but that premium buys a much larger data set and a broader toolkit that is easier to justify once you are managing multiple clients or channels.

Bottom line: Moz vs Semrush
Moz and Semrush both cover the SEO fundamentals, but they are built for different scales of work. Moz is the accessible, budget-friendly choice for beginners and small teams who want core rank tracking and audits without a steep learning curve.
Semrush is the heavier-duty platform for agencies and larger teams that need bigger databases, faster data refreshes, and marketing tools that extend well beyond SEO.
🔄 Switching? Keep in mind
If you outgrow Moz's data depth, you can export your tracked keywords and site audit history before migrating; Semrush's onboarding lets you re-import keyword lists directly into a new project.
Frequently asked questions
Is Moz cheaper than Semrush?
Yes. Moz starts at $49/mo ($39/mo billed annually), while Semrush starts at $139.95/mo, nearly three times as much. Moz also tops out lower, at $299/mo for its Large plan versus $499.95/mo for Semrush Business.
Is Moz or Semrush better for beginners?
Moz is generally easier for beginners. Its interface is simpler, its plans are more affordable, and Domain Authority gives new users a single, easy-to-understand metric to track. Semrush offers more power but has a steeper learning curve.
Does Moz or Semrush have better backlink data?
Semrush has a larger and more frequently updated backlink and keyword index than Moz. Moz's Link Explorer and roughly 500 million keyword database are solid for small sites but update and refresh more slowly than Semrush's.
Can I use Moz and Semrush together?
Yes, some teams run both: Moz for its Domain Authority benchmark and simpler day-to-day tracking, and Semrush for deeper keyword, backlink, and competitive research. For most small teams that is overkill, and one platform is enough.
Which is better for a small business?
For a single small business site, Moz is usually the better value: it costs less, is easier to learn, and covers the core SEO tasks most small sites need. Semrush makes more sense once you manage multiple sites or run PPC and content programs alongside SEO.
