The relative percentage of AI engine citations going to your competitors, compared to your brand, across a tracked prompt set.
Competitor share of voice measures how often each competitor in your defined competitive set is cited by AI engines, relative to your brand. The metric is typically displayed as a stacked bar or pie chart per prompt or in aggregate. Useful for identifying which competitors are winning AI mentions, where you have content gaps versus competitors, and how share of voice is shifting over time.
AEO is competitive — every citation that goes to a competitor doesn't go to you. Tracking competitor SOV identifies which competitors to focus on, which content topics to compete more aggressively on, and whether your AEO investment is gaining or losing ground against named competitors.
A B2B SaaS company in the project management category tracks SOV against Asana, Monday.com, ClickUp, and Linear. Their initial SOV is: Asana 35%, Monday 25%, ClickUp 15%, Linear 12%, Brand X (the customer) 13%. After 3 months of focused AEO content investment, Brand X's SOV grows to 22% while Asana drops to 28%. Lantern's monthly report visualizes this trend.
