02Pricing compared
Ahrefs has the lower listed entry price: Starter is $29 per month, but the main pricing page does not publish its limits. Its Free plan offers limited Site Explorer and Site Audit access. For published working limits, Lite costs $129 per month and includes 750 tracked keywords and 150 AI prompt checks.
Semrush’s Free plan includes one demo project and 10 reports per day. Its SEO plan costs $117.33 per month with annual billing, or $139 month to month, and includes 500 daily tracked keywords. Starter is $165.17 per month annually or $199 month to month. Ahrefs says annual billing saves up to 17%; Semrush lists annual and monthly prices. Compare what you need, not just the entry price: Ahrefs sells several add-ons, including Brand Radar AI from $199 per month, while Semrush lists extra users from $45 per month.
03Features and depth
Both cover keyword research, competitor analysis, rank tracking, site audits, and AI-search visibility. Semrush bundles keyword and backlink research, Position Tracking, Site Audit, content optimization, and AI visibility features across its plans, but the limits vary. Its SEO plan includes 500 daily tracked keywords and AI search performance and sentiment monitoring; Starter adds 50 tracked prompts per day and 300 AI visibility reports per day.
Ahrefs builds its SEO tools on its own web index and crawler data. Site Explorer covers competitor backlinks, traffic, and PPC strategy; Keywords Explorer finds opportunities and content gaps. Lite includes 750 tracked keywords, 150 AI prompt checks, and 100,000 monthly crawl credits. Brand Radar tracks brand mentions, citations, and sentiment in AI chatbots, but it is a paid add-on from $199 per month. Ahrefs also lists Letaido AI agents and Ask Ahrefs. The practical difference: Semrush bundles more AI visibility access into named plans, while Ahrefs separates some capabilities and reporting into add-ons.
04Ease of use and learning curve
There is no clear ease-of-use winner in the published reviews: both score 7 out of 10. Both products span several workflows, from keyword and competitor research to audits and tracking, so the better fit depends partly on which tasks your team already handles in one platform.
Semrush’s plans spell out daily keyword and prompt limits, which makes it easier to compare included capacity before switching. Ahrefs lists more detail by tier for Lite and above, but Starter’s limits are not published on the main pricing page. Its add-ons also mean you may need to price a specific workflow separately. Before moving, list the tools, users, and data limits you rely on, then compare them with the plan details—not just the interface or starting price.
