Citation data is the ground truth of AI search, and most tools measure it badly. I compare 9 AI citation analysis tools on engine coverage, sampling methodology, security, and price, and explain why a single-run citation check is statistical noise.
Every AI visibility number is a sample estimate, not a census. This reference defines 7 metrics (Citation Share, Time-to-First-Citation, Co-citation Rate, Fanout Uniqueness, Inline Hyperlink Share, Shopping Trigger Rate, Rank Stability) with formulas, 2026 benchmarks, and the sample sizes you need before a difference means anything.
Prompt volume is the AI-search equivalent of keyword volume: how often a prompt is sent to ChatGPT, measured via consented consumer panels. Here's how it works, how it differs from search volume, and why the metric matters in 2026.
13 AEO and GEO tools for marketers, grouped into 3 lanes: all-in-one platforms, purpose-built GEO trackers, and SEO suites with AI add-ons. With starting prices, funding data, and the Profound research stats that explain why AI search measurement got urgent in 2026.
Agent analytics measures AI crawler and assistant traffic through server logs and CDN integrations, the traffic GA4 misses entirely. Includes a bot user-agent reference table, an integration matrix, a diagnostic framework, and 2026 citation benchmarks.
I help plan Profound's Zero Click conferences, so I have a biased but informed take. Here's an honest practitioner ranking of the 13 events worth your 2026 conference budget, and the ones I'd skip.
The same page can be a top citation on ChatGPT and invisible on Perplexity. AI visibility isn't one number. Engines rewrite prompts differently, weight sources differently, and disagree on hostnames 65 to 85% of the time. Here's why, and what to do about it.
The 2026 competitor analysis stack pairs one SEO CI tool with one AI-search CI tool. ChatGPT and Google only overlap 12% of citations, and 97.4% of AI citations come from outside Tier-1 publishers. Profound leads AI-search CI with 1.5B+ prompts analyzed; Ahrefs leads traditional SEO CI; Visualping owns pricing-page monitoring.
