Know Your Share of AI Recommendations
Being mentioned is good. Being recommended more than your competitors is better. Track your Share of Model across supported AI platforms with the right methodological caveats.
What is Share of Model and why does it matter?
Share of Model (SoM) is VectorGap's audit-derived estimate of how often your brand appears relative to tracked competitors. In the current implementation it is calculated from mentions found in completed audit responses: (Your Mentions / Total Tracked Mentions) × 100. It is best used as a directional benchmark across a consistent prompt set, not as a claim of complete market coverage.
Share of Voice = (Your Mentions / Total Mentions) × 100Absolute vs Relative
100 mentions sounds good. But if competitors have 400 mentions, you're losing 80% of recommendations.
Leading Indicator
Share of Voice predicts market share. If SOV > market share, you're likely to grow.
Actionable
Low SOV in specific categories? Focus content there. Competitor spike? Investigate and respond.
How does VectorGap visualize Share of Model?
VectorGap can visualize Share of Model through competitive share, trend, platform, and query-cluster views where sufficient audit coverage exists. Some comparison layers remain heuristic and should be interpreted as directional diagnostics.

Frequently Asked Questions About Share of Model
Share of Model (SoM) is VectorGap's estimate of how often your brand is mentioned relative to tracked competitors across the prompts and providers you audit. In the current implementation it is derived from mentions found in completed audit responses, not from a complete census of every recommendation in your market.
Counting mentions only tells you absolute volume. Share of Model compares your mentions with the competitors and prompts included in your audit set, which makes relative movement easier to spot. It is directional rather than exhaustive.
VectorGap can break Share of Model estimates down by the providers included in your audits, including ChatGPT, Claude, Gemini, Perplexity, and Grok where those providers are enabled.
Share of Model views update when new audit data is available and snapshots are stored for your workspace. The exact cadence depends on the audits you run and the features enabled on your plan.
