Verified Pricing (May 2026)
Three important 2026 pricing updates: (1) Moz added a Starter plan at $49/month — any guide showing $99 as Moz’s entry price is outdated; that’s the Standard plan. (2) Ahrefs Standard ($249/month) and above now have unlimited fair use — credits only apply to Lite ($129) and new Starter ($29). (3) Semrush One bundles the SEO Toolkit with AI Visibility for comprehensive AI search tracking across ChatGPT, Gemini, and Google AI Overviews.
| Plan | Semrush | Ahrefs | Moz Pro |
|---|---|---|---|
| Entry paid | Pro $139.95/mo (5 projects, 500 keywords, 1 user) | Starter $29/mo (200 credits, limited tools) · Lite $129/mo (1,000 credits) | Starter $49/mo (1 site, 50 keywords) · Standard $99/mo (3 sites, 300 keywords) |
| Mid tier | Guru $249.95/mo (15 projects, 1,500 keywords, historical data) | Standard $249/mo (unlimited usage, 5 projects, 2,000 keywords) | Medium $179/mo (10 sites, 1,500 keywords, branded reports) |
| Advanced | Business $499.95/mo (40 projects, 5,000 keywords, Share of Voice, API) | Advanced $449/mo · Enterprise $1,499/mo | Large $299/mo (25 sites, 3,000 keywords) |
| Annual billing | ~17% savings on annual billing | ~20% savings on annual billing | ~20% savings on annual billing ($99 Standard → $79/mo annual) |
| Watch out for | Pro/Guru = 1 user. Extra users = $45/month each. Single-user agencies pay $45+/user/month before any collaboration is possible. Semrush One (AI Visibility) requires upgrade from base SEO Toolkit plan — pricing varies by tier. | Credits on Lite and Starter deplete fast for heavy users. Standard ($249/mo) is a significant jump from Lite ($129/mo) but delivers unlimited usage. Starter plan ($29/mo) lacks Keywords Explorer and many core tools — it’s not a functional full alternative to competitors’ entry plans. | Standard ($99/mo) only tracks 300 keywords — most active SEOs find they need Medium ($179/mo) almost immediately. Extra users cost $49/month each on Medium. Moz’s backlink index is slower than Semrush and Ahrefs — new backlinks appear days later. |
The Full Picture
Semrush — All-in-One SEO + Digital Marketing Platform
Semrush is the most comprehensive platform in the comparison — it covers SEO, PPC research, social media management, content marketing, PR monitoring, and competitive intelligence. For agencies managing multiple client campaigns across different digital channels, Semrush replaces several separate tools. The Pro plan at $139.95/month gives unlimited reports, 5 projects, and 500 tracked keywords. Unlike Ahrefs’ credit model (on Lite and below), you can run reports freely without worrying about hitting limits at any Semrush tier.
Semrush One (2026) is the most important product update in years. It bundles the core SEO Toolkit with the AI Visibility Toolkit — giving you a single subscription that tracks both traditional organic rankings and brand presence in AI-generated answers from ChatGPT, Gemini, and Google AI Overviews. As AI search increasingly surfaces content without users clicking to results, understanding whether your brand is cited in AI answers has become a meaningful marketing metric alongside traditional rankings. Semrush’s AI Visibility Toolkit lets you track 271M+ organic prompts, measure brand mentions, and compare AI visibility against competitors — capabilities that standalone tools charge significantly for.
The main frustration for teams: Pro and Guru plans include only one user seat. Additional users cost $45/month each. For a three-person agency team, that adds $90/month on top of the base subscription. The Business plan includes a better user model for larger teams, but at $499.95/month it’s significantly more expensive.
Ahrefs — Best Backlink Data, Unlimited on Standard+
Ahrefs has the most accurate and comprehensive backlink database available. For link building campaigns, competitive backlink gap analysis, and technical backlink audits, Ahrefs data is the industry standard for serious SEOs. In 2026, Ahrefs added two notable features: Brand Radar (track brand mentions across AI-generated content) and Ahrefs MCP (connect Ahrefs data directly to Claude and ChatGPT for AI-assisted SEO analysis), reflecting the broader shift in how SEOs use AI tools alongside research data.
The credit system clarification that many guides miss: Ahrefs Standard ($249/month) and Advanced ($449/month) plans now have unlimited fair use — there are no credit limits on these tiers. Credits only apply to the new Starter plan ($29/month, 200 credits) and Lite plan ($129/month, 1,000 credits). If you’re considering Ahrefs specifically because you heard about credit frustrations, the answer is: upgrade to Standard. The $120/month jump from Lite ($129) to Standard ($249) is significant, but it buys genuine unlimited usage and additional tools like Portfolios, Batch Analysis, and Content Explorer that aren’t available on Lite.
Ahrefs Webmaster Tools remains one of the best free tools in the category — free forever for verified site owners, providing backlink data, site audit, and organic traffic data for your own websites. If you’re just starting out and own a website, Webmaster Tools gives you meaningful data without any paid subscription.
Moz Pro — Most Accessible, New Starter Tier, DA Standard
Moz is the most accessible SEO tool in the comparison — its interface is the cleanest and most guided, keyword research is intuitive for non-experts, and the Domain Authority (DA) metric it invented has become the most-referenced site authority metric in marketing. When a client asks “what’s your DA?” or a link prospect lists “DA 40+” as a requirement, they’re referencing Moz’s proprietary metric — regardless of whether they actually use Moz.
The new Starter plan ($49/month) changes the entry-point story. Any comparison showing $99/month as Moz’s minimum price is using outdated information — $99 is now the Standard plan, not the entry tier. The Starter at $49/month supports 1 site, 50 tracked keywords, and 20,000 pages crawled. It’s a meaningful step down in capacity from Standard, but for a solo site owner with basic rank tracking and keyword research needs, it’s the most affordable professional SEO entry on the market. AI Visibility (in beta) and AI-powered keyword suggestions are included on the Starter plan at no extra charge.
The honest gaps in 2026: Moz’s backlink index remains the slowest of the three — new links often appear days after Semrush and Ahrefs detect them. The Standard plan’s 300-keyword limit is genuinely restrictive for active SEOs — most users find themselves upgrading to Medium ($179/month) within a few months. That said, the 30-day free trial on Standard and Medium is the most generous trial period in this comparison, and the MozBar Chrome extension (free) gives instant DA checks on any website for anyone doing quick competitive research.

Best Tool by Use Case
Hidden Costs & Gotchas
Semrush — Pro/Guru: 1 user only, extra users cost $45/month
Semrush Pro ($139.95/month) and Guru ($249.95/month) only include 1 user seat. Additional users cost $45/month each. A two-person team on Guru pays $249.95 + $45 = $294.95/month. A three-person agency team on Pro pays $139.95 + $90 = $229.95/month. Factor in user seats when comparing total monthly cost against Ahrefs (which includes multiple users on Standard+) and Moz (which includes 2 users on Medium).
Ahrefs — Credits on Lite run out faster than expected
Ahrefs Lite ($129/month) gives 1,000 credits/month. Every report, filter change, or data request consumes credits. Heavy users report hitting their limit in 2–3 weeks. If you regularly research competitors, analyze many keywords, or build detailed backlink reports, Lite’s credits will frustrate you. The solution is to upgrade to Standard ($249/month) where there are no credit limits. This $120/month jump is real — budget for it if your use case is heavy.
Ahrefs Starter ($29/month) is very limited — not a real alternative
The new Ahrefs Starter plan at $29/month is designed for basic access, not professional SEO work. It has 200 credits/month, no Keywords Explorer access, and very limited Site Explorer features. It’s better than the free tier but is not a functional substitute for Moz Starter ($49/month) or any full paid plan. Don’t evaluate it as an entry into professional SEO — it’s a step above Webmaster Tools for light users.
Moz Standard ($99/mo) only tracks 300 keywords — most upgrade immediately
Moz Standard at $99/month comes with 300 tracked keywords across 3 sites. For any active SEO campaign, 300 keywords fills up quickly — a single e-commerce site might track hundreds of product keywords. Most users who start on Standard upgrade to Medium ($179/month, 1,500 keywords) within their first month. Budget for Medium rather than Standard if you have more than one or two small sites to manage.
Moz entry is no longer $99 — Starter added at $49
Many comparison guides still show Moz’s entry as $99/month. That’s now the Standard plan. Moz added a Starter plan at $49/month (or $39/month annually) for single-site owners who need 1 campaign, 50 tracked keywords, and 20,000 pages crawled. If you only have one website and need basic rank tracking, Starter is worth considering before jumping to Standard.
Annual billing saves 17–20% on all three
All three platforms offer meaningful discounts for annual billing. Semrush: approximately 17% off monthly rate. Ahrefs: approximately 20% off. Moz: approximately 20% off (Standard drops from $99 to $79/month annually). If you know you’ll use the tool for at least 8–10 months, annual billing is clearly better value. Moz’s 30-day free trial on Standard and Medium lets you test extensively before committing to annual billing.
