Pricing: Plan by Plan
| Tier | Semrush | Ahrefs |
|---|---|---|
| Entry | — | Starter: $29/mo |
| Low-mid | Pro: $139.95/mo | Lite: $129/mo |
| Mid | Guru: $249.95/mo | Standard: $249/mo |

| Enterprise | Custom | $1,499/mo |

Ahrefs launched a $29/month Starter plan in January 2026 — a major shift. Semrush has no equivalent. If you want cheap SEO data, Ahrefs now wins on entry price by a wide margin.
At the mid-tier, both cost $249/month. The difference is what you get for that money.
$2,999 vs $2,988 /year
Semrush Guru: $249.95 × 12 = $2,999/year (or $2,500 annual billing)
Ahrefs Standard: $249 × 12 = $2,988/year (or $2,490 annual billing)
Nearly identical at mid-tier. The decision isn’t about price — it’s about what each tool does better.

Where Semrush Wins
- All-in-one marketing platform — SEO, PPC, social media, content marketing, local SEO. If you want one tool for everything, Semrush covers more ground. Ahrefs is SEO-only.
- Site audit — Semrush’s crawler catches more technical SEO issues and presents them more clearly. Their audit reports are easier to hand to a developer and say “fix these.”
- Content marketing tools — Topic Research shows what questions people ask. SEO Writing Assistant grades your content in real-time. Ahrefs has Content Explorer (find popular content by topic) but nothing for content creation.
- PPC research — Full ad copy analysis, CPC data, competitor ad tracking. If you run Google Ads alongside SEO, Semrush handles both. Ahrefs shows basic PPC data but isn’t built for paid advertising.
- Competitor traffic estimates — Semrush Traffic Analytics estimates any website’s traffic, sources, and audience demographics. Ahrefs shows organic keyword data but not traffic volume or sources.
- Multiple users on Guru — Guru includes 3 users. Every Ahrefs plan includes 1 user — extra seats cost $40-100/month depending on the plan.
Where Ahrefs Wins
- Backlink data quality — Ahrefs’ crawler updates its index faster and catches links that Semrush misses. For link building campaigns, Ahrefs’ backlink data is still the gold standard.
- Keyword difficulty scoring — more conservative and more accurate than Semrush’s. When Ahrefs says a keyword is KD 30, you can trust it’s achievable. Semrush’s difficulty scores tend to run higher, sometimes discouraging you from keywords you could actually rank for.
- Content Explorer — find the most shared and linked-to content on any topic. Brilliant for ideation and finding link-building opportunities. Search “best CRM” and see every article that earned links on that topic.
- $29 Starter plan — no other professional SEO tool offers this price point. It’s limited (100 monthly credits, basic features), but it’s real SEO data for less than a lunch tab.
- Cleaner interface — Ahrefs does fewer things, but the interface is less cluttered as a result. You find what you need faster. Semrush’s dashboard can feel overwhelming with all its modules.
- SERP overview clarity — Ahrefs’ keyword overview page shows the top 10 results with backlink counts, domain ratings, and traffic estimates in a format that’s immediately actionable.
The $29 Starter Plan: Game Changer?
Ahrefs launched Starter in January 2026. For $29/month you get:
- Site Explorer (analyze any domain’s backlinks and organic keywords)
- Keywords Explorer (limited to 100 monthly credits)
- Site Audit (1 project)
- Rank Tracker (basic)
100 credits means roughly 100 keyword lookups or domain analyses per month. For a freelancer managing 2-3 small sites, that’s enough. For an agency or in-house team doing daily research, you’ll burn through credits in a week.
Semrush has no $29 option. Their cheapest plan is Pro at $139.95 — nearly 5x more. For beginners or small-budget SEO practitioners, Ahrefs Starter is the obvious entry point.
Real Cost: Adding Users
This is where pricing gets sneaky.
| Scenario | Semrush | Ahrefs |
|---|---|---|
| 1 user, mid-tier | Guru: $249.95/mo | Standard: $249/mo |
| 3 users, mid-tier | Guru: $249.95/mo (3 included) | Standard: $249 + $80 × 2 = $409/mo |
| 5 users, mid-tier | Guru: $249.95 + $100 × 2 = $449.95/mo | Standard: $249 + $80 × 4 = $569/mo |
Semrush Guru includes 3 users. Ahrefs Standard includes 1. For a 3-person marketing team, Semrush is $160/month cheaper because you’re not paying for extra seats. This adds up to $1,920/year — real money.
Who Should Pick What
All-in-one marketing (SEO + PPC + social + content): Semrush. No other tool covers as many marketing channels in one subscription.
Pure SEO focus (link building + keyword research): Ahrefs. Better backlink data, more trusted difficulty scores, cleaner interface for SEO-specific workflows.
Beginner or small budget: Ahrefs Starter ($29/mo). Nothing else at this price gives you professional-grade SEO data.
Marketing team (3+ people): Semrush Guru ($249.95/mo). Three seats included saves $1,920/year over Ahrefs with added users.
Agency managing multiple clients: Semrush Business ($499.95/mo). White-label reports, API access, and client management features are built for agencies.
Link building specialist: Ahrefs Standard ($249/mo). The backlink index is faster and catches more links. Content Explorer finds link-worthy content. Link Intersect shows who links to competitors but not you.
Not sure? Start with Ahrefs Starter ($29/mo). Learn the basics. When you outgrow 100 credits, upgrade to Ahrefs Lite or switch to Semrush Pro depending on whether you need SEO-only or full marketing tools.
Frequently Asked Questions
Is Semrush or Ahrefs more accurate?
Both are estimates — no SEO tool has exact data. Ahrefs tends to be more accurate for backlink counts and keyword difficulty. Semrush tends to be more accurate for traffic estimates and competitive analysis. Neither is definitively “more accurate” across all metrics.
Can I use both?
Some agencies do. Run Ahrefs for backlink research and Semrush for content and competitive analysis. But $249 + $249 = $498/month is $5,976/year. Most businesses can’t justify both unless SEO drives significant revenue.
Do either offer free trials?
Semrush offers a 7-day free trial of Pro or Guru (requires credit card). Ahrefs offers free Webmaster Tools for your own site — no trial of paid plans, but the $29 Starter is low-risk enough to test.
Which is better for local SEO?
Semrush. Their Listing Management tool distributes your business info across directories and monitors reviews. Ahrefs has no local SEO features.
Are prices going up?
Both raised prices in 2025-2026. Ahrefs increased Lite by 30% ($99→$129) and Standard by 39% ($179→$249). Expect annual increases from both — SEO data is expensive to produce and both companies know their tools are sticky.
