Why this database is needed ​

Discussions about SEO tool pricing on the Chinese internet have long suffered from three problems:

  1. Citing outdated numbers: many comparison articles still use prices from two or three years ago; readers following these guides will inevitably hit pitfalls.
  2. Confusing "plans" with "actual usable scope": the boundaries between official seats, shared access, and node access are completely different.
  3. Comparing prices without comparing quotas: at roughly $100+ per month, some plans offer 5 projects while others offer 20; some allow 50K crawls while others allow 1.5M.

The goal of this database is to makebudget calculations evidence-based: check official quotas first, then decide whether to save.

I. Semrush SEO Toolkit: Official Pricing and Quotas ​

Semrush's official knowledge base pricing and limits page provides complete quotas for three tiers. The table below shows data collected on 2026-09-19:

Item Pro Guru Business
Official monthly price $139.95 $249.95 $499.95
Trackable websites 5 15 40
Trackable keywords 500 1,500 5,000
Monthly crawlable pages 100,000 300,000 1,000,000
Single report result limit 10,000 30,000 50,000
Monthly keyword metric updates 250 1,000 5,000
Monthly SEO Ideas items 500 800 2,000
Scheduled PDF reports 3 3 3

Semrush's official positioning for the three tiers: Pro for freelancers, small business owners, and SEO beginners; Guru for freelance SEOs and agencies; Business for teams and agencies.

How to choose among the three tiers: by task, not by price ​

  • Content ideation and keyword research only: 500 tracked keywords is enough for individuals. Pro's critical bottleneck is "250 keyword metric updates per month"—if you habitually check rankings daily, this quota runs out in a week.
  • Maintaining multiple client sites simultaneously: Guru's 15 monitored websites is the watershed; agencies typically start here.
  • Needing bulk exports and report delivery: the difference between 10,000 and 30,000 single report result limits is significant when exporting competitor long-tail keywords; Business's 50,000 is designed for batch operations.

About Semrush sharing and seats ​

Semrush's official seat management is a separate user management feature. The permissions, accessible project scope, and differences from the main account for sub-users added under one subscription are not identical. Before purchasing, clarify: do you needmultiple people logging in separately(official seats), orone subscription accessed by multiple nodes(node access). These two approaches differ completely in cost, compliance, and usage boundaries.

II. Ahrefs: Official Pricing and Quotas ​

Ahrefs' official pricing page (collected 2026-09-19) currently displays three self-service tiers:

Item Lite Standard Advanced
Official monthly price $129 $249 $449
Projects 5 20 50
Historical data 6 months 2 years 5 years
Trackable keywords 750 2,000 5,000
Track AI prompts 5 10 20
Monthly crawl credits 100,000 500,000 1,500,000
API and MCP access Yes Yes Yes
User credits 1,000 credits/user Unlimited Unlimited
Included users 1 1 1
Additional user price $40/month per additional user $60/month per additional user $80/month per additional user

The comparison reveals the pricing philosophy differences between the two companies:Semrush tiers by "keyword count + results limit", while Ahrefs tiers by "project count + historical data length + crawl credits". If you're mainly tracking "trends from the past six months", Lite's 6-month history is sufficient; once you need to make year-over-year seasonal judgments, Standard's 2-year history becomes the baseline.

One easily overlooked cost item: additional seats ​

In Ahrefs' legacy pricing system, adding users isbilled per seat separately. Taking Standard as an example, adding 2 seats means an extra $120 per month—for a 3-person team, the total jumps from $249 to $369. When budgeting, include seat fees in your calculation rather than just looking at the headline price.

III. Similarweb: Different Package Structure from the Other Two ​

Similarweb takes a different approach from the above two: the official Web Intelligence page displayspackage bundleswith prices and inclusions varying by region, currency, and page version; the company does not fix a set of "monthly list prices" on public pages.

Therefore, this article won't quote specific numbers for Similarweb, only providing structural explanations:

  • Official entry points exist for individual/self-service users, billed by different module combinations of Web Intelligence;
  • Deeper time periods, country and device breakdowns, keyword data, export, and API capabilities require higher-tier plans;
  • Enterprise-level needs typically require sales quotes.

The correct approach: frame Similarweb budget decisions around "what question are you trying to answer"—if you only occasionally need to check whether a competitor's traffic is in the millions or tens of millions, the public free entry is often sufficient; if you need to break down channel structure by country/device and export data, you must enter the paid tier.

IV. Putting "Official Subscription" and "Shared/Node Access" on the Same Table ​

A price database is easily misread without explaining access methods. The table below compares three common forms side by side:

Dimension Official Subscription Official Team Seats Shared/Node Access
Billing Entity Single account Main account + sub-seats Per node or per package
Project and Data Isolation Fully independent Depends on official permission settings Usually shares same resource pool
High-sensitivity client asset management Recommended Recommended Not recommended
API and long-term projects Supported Supported Subject to actual product page specifications
Cost Structure Highest Medium-high Usually lowest

The core conclusion of this table:The cost advantage of shared/node access is real, but it is not a substitute for official seats. When client data, long-term projects, API integration, and compliance requirements are involved, official plans remain the preferred choice; shared forms are better suited for individual learners, teams with limited short-term research budgets, and scenarios using multiple tools in parallel.

V. Checklist: Three Most Common Pitfalls ​

Pitfall 1: Treating "single report results limit" as "exportable row count" ​

Semrush's official "results per report" refers to the number of results a single report can return, not your account's total exportable rows. What actually hits limits first in batch operations are crawl page counts and keyword metric update quotas.

Pitfall 2: Ignoring monthly refresh quota consumption speed ​

Pro's 250 keyword metric updates per month may seem plenty. But if your habit is "refreshing rankings for 20 priority keywords every morning", that's 600+ times per month, guaranteed overage. Calculate this before choosing a planYour actual refresh frequency。

Pitfall #3: Budgeting by homepage price, forgetting seat fees and taxes​

In the table above, Ahrefs' additional seats are $40–$80/month/person; Semrush's official list price similarly excludes regional taxes. When purchasing for a team, use the formula "Total Price = Main Plan + Seats + Taxes" for budgeting.

FAQ​

Q: How often is this database updated?

A: Updated whenever official prices or quota pages change, with the new collection date noted at the top of the article. If you find discrepancies between the numbers here and official pages, the official pages take precedence.

Q: Why doesn't Similarweb show specific prices?

A: Because the official public page displays package combinations that vary by region and currency, with no fixed set of public monthly prices. Hardcoding numbers would be misleading, so this article only explains the structure.

Q: What's the most cost-effective approach with a limited budget?

A: First clarify what questions you need to answer. For keyword research only, Semrush Pro is sufficient; for competitor traffic estimation only, Similarweb's free tier is often enough; only consider shared/node arrangements to amortize costs when you genuinely need multiple tools in parallel—but don't put client-sensitive data in them.

Q: Does shared access affect the official account's quotas?

A: This depends on each product's implementation and product page description, varying by platform. Before purchasing, refer to that product's real-time product page and user console for quota information, not third-party reiterations.

Q: Are these prices tax-inclusive?

A: No. All figures in the table are official list prices, excluding regional taxes and currency conversion.
