Ahrefs vs AthenaHQ

Ahrefs is the research index: backlinks, keywords and Brand Radar's 475M-prompt AI visibility database across seven AI platforms, powered by the web's second-most active crawler. AthenaHQ tracks brand visibility across up to nine AI models with prompt and response analysis, competitor insights, and content optimization agents, with a real free tier. They compete only where the categories overlap, and the chapters below walk every dimension a buyer would price: which AI engines each can see, how the tracking actually meters, what each produces on the content side, what surrounds the core product, and the full published tier lists.

Ahrefs is one of the great research platforms in search, powered by the web's second-most active crawler and 10+ years of web-scale data. Alongside Site Explorer's backlink index, Keywords Explorer, Site Audit and Rank Tracker, it now runs Brand Radar: an AI visibility database of 475M+ monthly search-backed prompts spanning AI Overviews (323M), ChatGPT (31M), Gemini (31M), Copilot (30M), Perplexity (30M), AI Mode (21M) and Grok (6M), with YouTube, TikTok and Reddit source tracking in beta. Their FAQ is blunt about discounts: they never run them.

Pricing model. Lite $129, Standard $249 and Advanced $449 a month (annual saves up to 17%), plus a $29 Starter and a free tier for site owners; full Brand Radar runs $398 (selected platforms) to $699 (all platforms), custom prompt packs start at $50 for 2,500 checks, and Enterprise is $1,499 a month with an annual commitment.

AthenaHQ is a San Francisco AEO platform with strong review credentials: a G2 High Performer for Answer Engine Optimization (Spring 2026) and 4.9-out-of-5 ratings on its badges. The product analyzes prompts and responses across up to nine AI models, estimates prompt volumes numerically, tracks unlimited competitors with sentiment, and acts through on-page and off-page GEO actions, a content optimization agent, smart robots.txt and llms.txt management, and an enterprise citation engine (ACE). Unlimited seats with role-based access come on every plan, and it publishes its own comparison pages against Profound, Peec, Scrunch, Semrush and Ahrefs.

Pricing model. Essential is free with a $25 credit (300 credits, five models including Claude); Starter is $295 a month with a $300 monthly credit (3,600 credits, nine models), with API access and extra credits as paid add-ons; Enterprise is custom with annual 17% off available.

Ahrefs. Brand Radar's index covers seven platforms: AI Overviews, AI Mode, ChatGPT, Copilot, Gemini, Perplexity and Grok, an index built from 475M+ monthly search-backed prompts. Claude and DeepSeek appear nowhere on the pricing or Brand Radar pages, and the $398 platform picker lists five options that do not include Grok.

AthenaHQ. The free Essential tier covers ChatGPT, Perplexity, AI Overviews, Gemini and Claude; Starter adds AI Mode, Copilot and Grok for visibility across nine models, with additional models available on request. Claude ships from the free tier, which is rare in this set; DeepSeek does not appear on the page.

Summarized: Ahrefs reads index across AIO, AI Mode, ChatGPT, Copilot, Gemini, Perplexity, Grok; AthenaHQ reads 5 free; 9 on Starter (incl. Claude, Copilot, Grok, AI Mode). On Claude specifically, Ahrefs: not listed anywhere; AthenaHQ: yes, from the free tier.

Ahrefs. Tracking your own prompts is metered three ways: 5 to 20 tracked AI prompts with 150 to 600 monthly checks on the core plans (updated daily), custom prompt packages from $50 a month for 2,500 checks with per-check overage, or full Brand Radar at $398 to $699. The Google Rank Tracker updates weekly on every tier including Enterprise, with 750 to 5,000 tracked keywords.

AthenaHQ. Metering is credit-based with one credit equal to one AI response: 300 credits free, 3,600 on Starter, custom on Enterprise. Tracking includes unlimited topics, numerical prompt-volume estimation, unlimited competitor tracking and benchmarking, prompt variations with conversation context, and real-time brand sentiment.

Ahrefs. The Content Kit add-on, from $99 a month, is an AI Content Helper and Grader that aligns drafts with search intent and scores them, with an AI Content Inventory marked Soon. Nothing on the pricing page writes full articles or publishes to a CMS.

AthenaHQ. Content recommendations ship on the free tier and a content optimization agent from Starter, with brand voice and guideline enforcement, on-page and off-page GEO actions, and Shopify and Webflow integrations. The enterprise Athena Citation Engine and Recommendation Engine extend the action layer; there is no long-form article pipeline described.

Ahrefs. Classic SEO research is the backbone: the backlink index, Keywords Explorer, Site Audit with 100K to 1.5M crawl credits by tier, and Web Analytics plus Bot Analytics. A GBP Monitor ships in beta; no geo-grid or map-pack tracking appears on the pricing page.

AthenaHQ. There is no Google organic rank tracking and no local surface on the pricing page. GA4 and Google Search Console integrations connect AI visibility with site traffic, which correlates traffic with visibility; position measurement is a different job.

Ahrefs. API access and an MCP server ship on all tiers with rows metered by plan (100 to 500 rows per request, uncapped on Enterprise), plus a Looker Studio integration from Advanced and Report Builder as an add-on. Export rows run 500K to 4M a month by tier.

AthenaHQ. CSV export ships from Starter, GA4 and GSC integrate, and API access is an optional paid add-on billed on top of the Starter subscription, included only on Enterprise. Enterprise adds SAML and OIDC SSO, audit logs, multi-region and multi-language support, and executive dashboards with Tableau, Power BI and Looker support. No MCP server is listed.
