Semrush vs Ahrefs: which is better?
Semrush is better if you want one tool for everything: keyword research, site audits, local SEO, PPC research, content tools and AI search tracking. Ahrefs is better if backlinks and link building are the core of your work, thanks to its huge link index and a cleaner, faster interface. Both cost about the same at the middle tier ($249.95 for Semrush Guru vs $249 for Ahrefs Standard). For agencies and all-round marketers, pick Semrush. For link builders and technical SEOs, pick Ahrefs.
At CompareBestAI, we compared both tools on the same website, looking at keyword data, backlink counts, site audit findings, AI visibility features, and what each costs once you add the seats and add-ons most teams need.

Semrush vs Ahrefs for keyword research
Both tools are excellent here, and the gap is smaller than most comparisons suggest.
Semrush shines on keyword intent labels, SERP feature data and PPC metrics like CPC and competition, which matters if you also run Google Ads. Its Keyword Magic Tool makes it easy to group thousands of long-tail ideas.
Ahrefs gives clean click-based data, showing how many searches actually lead to clicks. That's useful when AI Overviews answer the question on the results page and fewer people click through.
- Pick Semrush if you mix SEO with PPC or need intent labels at scale.
- Pick Ahrefs if you care most about realistic click potential.
Semrush vs Ahrefs for backlinks
This is Ahrefs' home ground. Its crawler is one of the most active on the web, and its link index is the reason many SEOs pay for it. Finding new and lost links, broken links you can reclaim, and competitors' best-linked pages is fast and reliable.
Semrush's backlink database has grown a lot and is good enough for most businesses. But if link building is your main job, Ahrefs is still the safer choice.
Is Ahrefs more accurate than Semrush for backlinks?
For backlink discovery, Ahrefs is generally considered stronger thanks to its large, frequently updated link index. Semrush's link data is solid for everyday competitor research, but dedicated link builders usually prefer Ahrefs.
Semrush vs Ahrefs for site audits, local SEO and competitor analysis
Site audits: both crawl your site and flag technical issues like broken links, slow pages and missing tags. Semrush gives more guidance on how to fix each issue, which helps beginners. Ahrefs' audit is fast and clean, and its free Webmaster Tools let you audit sites you own at no cost.
Local SEO: Semrush wins, with a dedicated local toolkit for listings and map rankings (sold as an add-on from about $30 a month). Ahrefs has no comparable local suite.
Competitor analysis: Semrush gives a wider view, including paid ads, traffic estimates and content gaps. Ahrefs is sharper on competitors' links and top pages.
Semrush vs Ahrefs pricing: what you really pay
Sticker prices look close. Seats and add-ons are where bills pull apart.
| Plan | Price/month | Included users | Extra user |
|---|---|---|---|
| Semrush Pro | $139.95 | 1 | $45 |
| Semrush Guru | $249.95 | 1 | $80 |
| Semrush Business | $499.95 | 1 | $100 |
| Ahrefs Lite | $129 | 1 | $40 (max 2 extra) |
| Ahrefs Standard | $249 | 1 | $60 (max 5 extra) |
| Ahrefs Advanced | $449 | 1 | $80 (max 10 extra) |
What a 3-person team pays per month:
- Semrush Guru: $249.95 + 2 × $80 = $409.95
- Ahrefs Standard: $249 + 2 × $60 = $369
Two more costs to plan for:
- Ahrefs Lite has a credit cap of about 1,000 credits per user per month. Heavy research can hit it, which is why many users treat Standard ($249) as the real starting point.
- Semrush gates features by tier. Content tools and historical data start on Guru, and API access on Business.
Is Semrush or Ahrefs cheaper?
Ahrefs is slightly cheaper at each tier and for teams. A 3-person team pays about $369 a month on Ahrefs Standard versus about $410 on Semrush Guru. Solo users can start cheaper on Ahrefs Lite ($129) or even Starter ($29), though both have limits.
Our guide to the hidden costs of AI tools explains how seats and add-ons inflate SEO tool bills.
AI search visibility: which tracks ChatGPT and AI Overviews better?
Both tools now track how brands appear in AI answers, a big shift in 2026.
- Semrush sells an AI Visibility Toolkit for $99 a month as an add-on, or bundles it into Semrush One plans from $199 a month. Note that extra team members need their own $99 AI Visibility seat.
- Ahrefs sells Brand Radar AI from $199 a month, separate from its core plans.
If AI visibility is a priority, Semrush One Starter ($199) is usually the cheaper all-in package. Search Engine Land's guide to generative engine optimization is a useful primer on why this tracking matters. Our guides on how to track AI search visibility and the best GEO tools go deeper.

Semrush pros: widest toolset, strong local and PPC data, beginner-friendly guidance, bundled AI visibility option Semrush cons: pricier per seat, key features gated behind Guru and Business, add-ons add up fast
Ahrefs pros: best-in-class backlink data, clean fast interface, free Webmaster Tools, slightly cheaper for teams Ahrefs cons: Lite's credit cap, no local SEO suite, AI tracking costs extra from $199
