Ahrefs vs Semrush (2026): Pricing, Data and Which SEO Tool to Buy

Short answer: pick Ahrefs if backlink research and a clean, fast interface for SEO work are your priority; pick Semrush if you want the broader platform, with more websites and tracked keywords per plan, content optimization and AI search visibility tracking bundled into its tiers. Entry prices are close: Ahrefs Lite is $129 a month and Semrush’s SEO plan is $139 a month. If both feel expensive, SE Ranking’s Core plan ($129 a month, or $103.20 on annual billing) tracks four times as many keywords as either entry plan.

All prices and limits below are vendor-published, checked September 2026 on ahrefs.com, semrush.com and seranking.com, in USD on monthly billing unless noted.

Ahrefs vs Semrush at a glance

Ratings from real users are on the Ahrefs vs Semrush comparison page.

Which is better, Ahrefs or Semrush?

Neither wins outright. Ahrefs is better for link building and competitive research on a focused SEO team, thanks to its own web crawler and index and simple per-project limits. Semrush is better for agencies and marketing teams that manage more sites and keywords per plan and want content optimization and AI visibility reporting in the same subscription.

Both tools cover the same core jobs: keyword research, competitor analysis, backlink analysis, site audits and rank tracking. The differences are in how they package limits, how they charge for extra users, and which add-ons you need.

Ahrefs describes itself as an AI marketing platform built on its own web index, and positions its crawler as the world’s second-most active. Its plans scale by projects, tracked keywords, crawl credits and years of historical data. Semrush scales by websites monitored, keywords tracked daily and AI prompts tracked, and layers on toolkits and reports as add-ons.

How much do Ahrefs and Semrush cost?

On monthly billing, Ahrefs runs $129, $249 and $449 for Lite, Standard and Advanced, with Enterprise at $1,499 on an annual commitment. Semrush runs $139 for SEO, $199 for Starter, $299 for Pro+ and $549 for Advanced. Both take up to 17% off for annual billing, and both charge extra for additional users.

Extra seats change the total quickly. Ahrefs includes one user on Lite, Standard and Advanced, then charges $40, $60 or $80 per additional user per month respectively (Enterprise: $100). Semrush’s additional users start at $45 per month. A three-person team on Ahrefs Standard pays $249 + 2 × $60 = $369 a month, our arithmetic from the list prices. See Ahrefs pricing for the plan breakdown.

Which has better backlink data?

Ahrefs is the usual choice for backlink-heavy work because its link tools are built on its own crawler and index, and its Standard plan adds broken backlinks, broken links, outgoing links and linking-author reports. Semrush also offers backlink analysis and competitor tools on every plan. For link building as a core job, most SEOs start with Ahrefs.

Data sizes change constantly and each vendor measures them differently, so the most reliable test is your own: run the same three competitor domains through both free trials or free plans and compare referring domains you already know exist.

Which is better for keyword research?

Both are strong. Ahrefs’ Keywords Explorer on Standard adds AI keyword suggestions, keyword clusters, search intents and translations. Semrush’s higher tiers add content optimization and keyword cannibalization analysis (Pro+) and SEO share of voice (Advanced). Teams that write a lot of content often prefer Semrush’s optimization tools; researchers often prefer Ahrefs’ interface.

If your keyword work leads straight into content briefs, check Ahrefs’ Content Kit add-on (from $99 a month, including an AI content helper and grader) against Semrush Pro+, which bundles content optimization in the plan.

Which is better for rank tracking?

Ahrefs tracks more keywords at each entry tier (750 on Lite versus Semrush’s 500), while Semrush states that its tracking updates daily and adds multi-location and device tracking from Pro+. For large keyword sets, compare Ahrefs Advanced (5,000) and Semrush Advanced (5,000), which match on volume.

If rank tracking is the main thing you need, a dedicated rank tracker or SE Ranking may cost less than either platform. SE Ranking’s Core plan tracks 2,000 keywords daily.

Which is better for technical site audits?

Both include a site audit on every paid plan. Ahrefs meters audits by crawl credits: 100,000 a month on Lite, 500,000 on Standard and 1.5 million on Advanced, with an always-on audit and optional Project Boost add-ons for faster recrawls. Semrush includes Site Audit on all plans and adds an AI-ready Site Audit on its SEO + AI Search tiers.

For a single site with a few thousand URLs, either tool is plenty. For large e-commerce or publisher sites, check the crawl budget first: Ahrefs’ credits are a hard monthly number you can plan around, and its Project Boost Pro add-on ($20 a month per project) adds instant recrawls and IndexNow auto-submission. Semrush sizes audits within each plan’s limits, so compare the page quotas in its plan table against your site’s URL count before buying.

Which is better for agencies?

Semrush usually fits agencies better on volume, with up to 40 monitored websites and 5,000 daily-tracked keywords on Advanced, plus an Agency Partners listing add-on for lead generation. Ahrefs fits agencies that value deep link research and are willing to pay per extra seat; its Advanced plan covers 50 projects and 10 additional users.

Reporting is the other agency question. Ahrefs sells Report Builder at $99 a month (50 reports, 500 widgets, scheduling) and adds a Looker Studio integration on Advanced. Semrush sells reporting as add-ons, starting with Base Report at $10 a month for scheduled PDF reports with Google Analytics and Search Console data. SE Ranking’s Agency Pack adds white-label reporting and 30 client seats for $69 a month on annual billing.

Which tracks AI search visibility better?

Semrush bundles more AI prompt tracking into its main plans: 50 prompts on Starter, 100 on Pro+ and 200 on Advanced, plus AI visibility reports and sentiment monitoring. Ahrefs includes 5 to 20 tracked AI prompts on its main plans and sells Brand Radar AI, which researches brands across its prompt database, from $199 a month.

Both vendors now offer MCP access so AI assistants can query their data directly. Ahrefs lists API and MCP access on Lite and above; Semrush lists MCP access from Starter.

Is SE Ranking a cheaper alternative to both?

Yes, for most small teams. SE Ranking Core costs $129 a month, or $103.20 a month on annual billing, and includes 10 projects, 2,000 keywords and 100 AI prompts tracked daily, 250,000 audited pages a month, unlimited keyword, competitor and backlink research, and a 14-day free trial without a credit card.

SE Ranking Growth ($279 a month, or $223.20 annually) raises limits to 30 projects, 3 manager seats and 5,000 keywords, and adds historical data across the project lifetime. Agencies can add white-label reporting through the Agency Pack at $69 a month on annual billing. The tradeoff is ecosystem depth: Ahrefs and Semrush offer larger add-on catalogs and more third-party training material. See SE Ranking reviews.

What are the cons of Ahrefs?

Ahrefs charges per extra user on every plan below Enterprise, caps Lite at 1,000 credits per user, limits Lite to 6 months of historical data, and puts features like Content Explorer and broken-link reports behind Standard. Its Enterprise plan requires an annual commitment at $1,499 a month.

Can Semrush be trusted?

Yes. Semrush has operated since 2008, was listed on the New York Stock Exchange in 2021, has its headquarters in Boston, and became an Adobe company in 2026, according to its company page. Its free plan and trial let you check its data against your own Google Search Console numbers before paying.

That also answers a common question: Semrush registered as a U.S. company in 2012 and runs offices across the U.S. and Europe. Ahrefs is headquartered in Singapore.

Who should choose Ahrefs?

• Link builders and digital PR teams who live in backlink reports.
• In-house SEO teams with one to three main sites and a small number of users.
• Teams that want many years of historical data (up to 5 years on Advanced).
• Technical SEOs who will use API and MCP access from the Lite plan up.

Who should choose Semrush?

• Agencies monitoring many client sites (up to 40 on Advanced).
• Content teams that want optimization and cannibalization analysis bundled in.
• Marketing teams that want AI search visibility reporting on a standard plan.
• Teams that want reporting add-ons (Base Report from $10 a month) and other marketing toolkits from one vendor.
