A GEO tool earns its price when it tells you what to fix, not just your score: the reference framework is a 9-dimension audit covering AI Citation Score, Answer Readiness / LLMO, Brand Signals, Entity Clarity, Content Depth, Platform Readiness, Technical Foundation, Source Authority, and Media Readiness.
This hub collects GeoXylia's tools and comparisons cluster: what an AI visibility audit should cover, what the main platforms cost, and how to evaluate them honestly. The tools market split into two camps in 2026: measurement platforms that track citations and share of voice across engines, and audit-and-prescription tools that score your site against the dimensions above and tell you what to change. The second camp is where the reference framework lives, and it is what this cluster documents.
Who is this for? Marketers choosing their first GEO tool, agencies standardizing on a stack, and teams deciding whether to pay at all. Pricing ranges from free to $499/mo, and the gap between tiers is mostly coverage and automation, not quality of insight. The research-based rule in this cluster: comparison content carries a 76% citation rate, the second-highest of any format, which is exactly why these tool pages are built as side-by-side comparisons with verified numbers.
What should a GEO tool actually measure?
Judge any tool against the 9-dimension framework. AI Citation Score tracks how often and where you are cited across engines. Answer Readiness / LLMO checks whether your pages answer the exact queries AI retrieves for. Brand Signals covers mention consistency and off-site presence. Entity Clarity covers Wikidata, knowledge panel, and schema identity. Content Depth measures whether pages are substantive enough to be extracted. Platform Readiness checks crawler access and per-engine fit. Technical Foundation covers rendering, performance, and structure. Source Authority weighs the independence of your citing sources. Media Readiness covers images, video, and transcripts. A tool that reports one composite number without dimension-level detail cannot tell you where to work, and a tool that never updates its engine coverage is tracking a market that changes weekly. Ask what changes a vendor recommends, not just what they measure.
How much do GEO tools cost, and what do you get at each tier?
Verified 2026 pricing: GeoXylia free, $29/mo, and $149/mo; Otterly $29-189/mo; Profound $99-499/mo; Ahrefs Brand Radar from $199/mo; Semrush AI Visibility $99/mo per domain; Peec from about EUR 89/mo. The pattern is consistent across vendors: entry tiers cover one or two engines with a limited prompt set, mid tiers add multi-engine tracking and share of voice, and top tiers add competitor benchmarking, agency features, and historical data. The value is not in the price point but in the loop it closes. Measurement-only tools show you a score and leave the fix to you; audit tools score against the 9 dimensions and produce a prioritized change list. For most B2B teams, the free tier of an audit tool plus a manual prompt set beats a paid monitoring tool that never recommends an action.
Do I need a paid tool to start?
No, and starting free is better because it builds the habit before the budget. Run a free audit to get your baseline against the 476-site benchmark, then verify by hand: in a private window, ask your top 10 customer questions across ChatGPT, Perplexity, and Google AI Overviews, record which sources are cited, and repeat twice on the same day because same-day variance runs 10-18%. Do this weekly for a month and you will see patterns no single snapshot shows. Upgrade to a paid tier when you need competitor share of voice, historical trends, or tracking across more than three engines on a schedule. The audit guides in this cluster walk through both paths, and the platform comparison matrix shows exactly which features each vendor covers at each price.
