Your brand's percentage of total citations across AI answer engines for a defined set of prompts in a category — the AEO equivalent of share of voice in advertising.
If five competitors are mentioned across 100 prompts and your brand appears in 23 of those mentions, your AI Share of Voice is 23%. This is one of the most actionable AEO metrics because it is directly comparative: gaining share comes at the expense of a specific competitor, which lets you build targeted content plans.
VibecodeAEO computes share of voice per engine, per category, and per prompt cluster — so you can see, for example, that Perplexity favors your competitor on “best B2B CRM” while Gemini favors you, and prioritize accordingly.
A project management SaaS tracks 50 buyer prompts. They appear in 18 — a 36% share of voice. Their top competitor appears in 41. By analyzing which prompts they are missing, they identify 8 content gaps, publish articles targeting them, and lift their share to 52% over 6 months.
VibecodeAEO scans your site for all AEO factors weekly and tells you exactly what to fix.
