Share of voice by engine
Track AI share of voice separately per engine — your ChatGPT SOV may be very different from your Perplexity SOV. Buyers use different engines for different query types, so a platform-specific breakdown shows where you're winning and where you have gaps. Most brands start stronger on one engine and close the gap on others over time as their GEO work compounds.
