Ahrefs vs Moz

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. Moz, a Ziff Davis company, is the veteran SEO suite: Domain Authority, a 40-trillion-link index, keyword research, site crawls, and an AI module tracking two to three models weekly. They compete only where the categories overlap; the ledger below lines them up dimension by dimension so the differences carry the decision.

Every cell below was read from the vendor’s own rendered pages (ahrefs.com/pricing and /brand-radar; moz.com/products/pro/pricing and /products/local), as of August 2026. Where a vendor’s public pages neither confirm nor deny a capability, the cell says so.

Open questions on each side, from the same rendered pages. Ahrefs: claude and DeepSeek absent from the AI lineup; google rank updates are weekly on every tier; aI prompt tracking metered small on core plans. Moz: claude and Perplexity absent from the tracked models; weekly cadence on both AI and rank tracking; content output stops at briefs.

Rank.ai is built for the loop that usually falls between these two products. It puts your market’s buying questions to seven AI engines every day, ChatGPT, Claude, Gemini, Perplexity, Grok, Google AI Overviews and DeepSeek, three samples per engine, and records every answer with the brands named and the sources cited. It checks your Google rankings daily on every plan and scans a geo-grid of your Google Maps rank across your service area. And it finishes the job: the article pipeline researches, writes and publishes the missing pages into WordPress, Webflow, Shopify or WordPress.com with your approval, 10 a month included on the $0 plan.
