Ahrefs

Ahrefs

Ahrefs is one of the two dominant SEO platforms, built on its own crawler and backlink index, and its AI layer is substantive rather than bolted on. Brand Radar analyzes brand and entity visibility across six AI surfaces — Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini, and Copilot — against an index of 271M+ organic prompts, so you get retroactive AI-mention data with zero setup. Ahrefs pairs that with AI Content Helper for grading and improving pages, and a set of free AI tools that serve as the on-ramp to the full platform.

Production credibility: Founded 2010 by Dmytro Gerasymenko; HQ Singapore; famously bootstrapped — no venture funding — at an estimated $149M revenue in 2024 (GetLatka estimate). Vendor-reported: 44% of the Fortune 500 use Ahrefs, with roughly 20k new users joining weekly.

Key Features

• Brand Radar: AI Mentions, AI Citations, and AI Share of Voice across six AI surfaces
• 271M+ organic-prompt index — retroactive AI-visibility data with zero setup
• Custom prompt tracking for the questions that matter to your brand
• AI Content Helper: content grading, improvement suggestions, and inventory
• Cross-references AI mentions with branded search demand and the Ahrefs backlink dataset
• Free AI Visibility Checker and writing tools as entry points

Ideal Use Case

SEO teams that live in crawler-scale data — backlinks, keywords, site audits — and want AI-answer visibility measured from the same vendor, with retro prompt data instead of starting tracking from scratch when the AEO question lands on their desk.

How Ahrefs differentiates

Where SurferSEO and Frase operate at the document level, Ahrefs operates at the index level: its moat is proprietary crawl and prompt data no content editor can match, making Brand Radar closer to 'Ahrefs for AI answers' than to a writing assistant. Known gaps per third-party 2026 reviews: no Claude or Grok tracking, and non-Google chatbot data refreshes monthly.

FAQ

Q: What is Ahrefs? A: Ahrefs is an SEO platform built on its own web crawler — backlink analysis, keyword research, rank tracking, and site audits — now extended with Brand Radar, which tracks brand visibility across AI answers on six surfaces including ChatGPT and Google AI Overviews.

Q: How much does Ahrefs cost? A: The Starter plan is $29/month; core plans run Lite $129, Standard $249, Advanced $449, and Enterprise $1,499 per month. Brand Radar is available standalone from $199/month, and AI Content Helper ships in the $99/month Content Kit add-on.

Q: What is Brand Radar? A: Brand Radar is Ahrefs' AI visibility product. It measures AI Mentions, AI Citations, and AI Share of Voice across Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini, and Copilot, using an index of 271M+ real prompts — so historical data exists the day you start.

Q: How is Ahrefs different from Semrush? A: Both are index-scale platforms with AI visibility tracking. Ahrefs is bootstrapped and engineering-led, anchored on its crawler and prompt index, with a cheaper $29 entry point; Semrush is broader (ads, social, content) with Copilot coverage and daily multi-LLM refresh. Teams usually standardize on one.

Q: Does Ahrefs have a free plan? A: Ahrefs offers free tools — including an AI Visibility Checker and Ahrefs Webmaster Tools for site owners — but full platform access starts with the $29/month Starter plan.

tl;dr

Ahrefs brings crawler-scale data to AI search: Brand Radar tracks mentions, citations, and share of voice across six AI surfaces against a 271M-prompt index, next to the backlink and keyword tools SEO teams already use. Bootstrapped, ~$149M revenue (2024 est.), from $29/month. The index-level alternative to Semrush.
