Semrush vs Ahrefs is the question every SEO team asks at renewal time. Both are big, both cost over $100 a month, and both do most of the same jobs. This comparison looks at where they differ in 2026: price and seat costs, keyword data, backlink index, rank tracking, site audit, and AI search tracking. Every number comes from the two pricing pages on September 16, 2026.
We build Zutrix, a smaller SEO platform that competes with both on rank tracking. We are not neutral. We keep our own product to one clearly marked section and let the numbers argue the rest. If you want to see how Zutrix stacks up, our Semrush alternatives and Ahrefs alternatives guides cover it.

Pricing and seats
The headline prices are ten dollars apart. Semrush's entry SEO plan is $139 a month. Ahrefs Lite is $129. Annual billing takes about 17 percent off both. Where the bills diverge is above the entry tier. Semrush Pro+ is $299 and Advanced is $549. Ahrefs Standard is $249 and Advanced is $449. At the middle tier Ahrefs is $50 cheaper.
Seats matter more than most buyers expect. Both tools include one user. Semrush charges from $45 a month per extra user. Ahrefs charges $40 on Lite, $60 on Standard, and $80 on Advanced, and caps how many you can add. A three person team on either entry plan pays around $220 a month. Read Semrush pricing and Ahrefs pricing for every plan.
The cheapest way in is different for each. Ahrefs has a $29 Starter plan with Site Explorer and Keywords Explorer on credits. Semrush has a free account with 10 requests a day. Neither is enough for daily agency work, but both are enough to learn the tool.

Keyword research
Semrush's Keyword Magic Tool has the larger database, with 25 billion plus keywords across 140 plus countries. It groups keywords, tags intent, and shows a difficulty score that runs a little high. Ahrefs Keywords Explorer has a smaller but still huge database. It adds two things Semrush does not: click estimates, and a parent topic that shows which broader term the keyword belongs to. As a keyword research tool, each has a clear edge.
In practice, both find the same head terms. Semrush finds more long tail variants. Ahrefs tells you more about each one. For content planning, many teams prefer Ahrefs. For PPC keyword lists, Semrush's size helps. Our guide on how to find long tail keywords uses both.
Backlink data: Ahrefs vs Semrush as a backlink checker
This is where Ahrefs built its name. Its crawler is second only to Google in activity, and the backlink index updates fast. Domain Rating is the most quoted authority score after Moz's DA. Site Explorer shows new and lost links, anchor text, and linking pages with a speed Semrush does not match.
Semrush's backlink database is large and has closed most of the gap. Its Backlink Audit tool is stronger for finding toxic links and building a disavow file. For link building research and competitor link analysis, Ahrefs still wins. For cleaning up a bad profile, Semrush is the better workflow. Our toxic backlinks guide explains when that matters.
Rank tracking
Neither tool is a rank tracker first. Semrush Position Tracking updates daily and tracks 500 keywords on the entry plan across 5 projects. It has good local and mobile options. Ahrefs Rank Tracker covers 750 keywords on Lite, but update frequency depends on your plan, and it shows fewer SERP features.
If rank tracking is your main job, the math is bad for both. You pay $129 or $139 for a few hundred keywords and a lot of tools you may not open. A dedicated tracker gives you more keywords, daily updates, and proof for far less. Our best rank tracker tools roundup compares the options.
Site audit
Both crawl up to about 100,000 pages a month on the entry plan. Semrush Site Audit groups issues into themes and gives a health score that clients like. Ahrefs Site Audit is faster to set up and its issue explanations are clearer. Ahrefs also gives the audit away free in Webmaster Tools for sites you own. For technical work, both are fine. Neither replaces a desktop crawler on a very large site.
AI search tracking
Both tools added AI visibility in 2025 and 2026. Semrush bundles 50 tracked prompts into its Starter tier at $199 a month and sells an AI Toolkit on its own. Ahrefs includes 5 tracked prompts on Lite and sells Brand Radar from $199. Both are add-ons in effect. If AI search matters to you, see our roundup of the best AI visibility tools before paying either price.
Interface, learning curve, and support
Ahrefs is cleaner. Most reports are two clicks from the home screen and load fast. Semrush has more tools, so it has more menus, and new users spend a week finding things. Both have good documentation. Semrush has a larger academy with certifications. Ahrefs has better free video training on YouTube.
