The Verdict: Ahrefs has become arrogant. They introduced a "credits" system that charges you extra for basic clicks. In contrast, Semrush gives you unlimited data, a 25% larger keyword database, and a fully functional free trial.
- 25 Billion Keyword Database
- Includes Social Media & Content Tools
- Free Trial Available (Ahrefs has none)
The "Usage-Based" Pricing Trap
The biggest reason we stopped recommending Ahrefs in 2025 is their new pricing model. Even if you pay $199/month, you are limited by "credits." If you do deep keyword research, you will hit your limit in week 2 and have to pay more.
Semrush acts like a buffet. You pay one price, and you can eat as much data as you want. For agencies and serious marketers, this is the only viable option.
| Feature | Ahrefs | Semrush |
|---|---|---|
| Free Trial | Paid Only ($99) | 14 Days Free |
| Usage Limits | Credit Based | Unlimited |
| Support | Email Only | Chat + Phone |
