Relative ad weight
A rival at 32% SOV is likely spending ~$71,111/month — about $31,111 more than you. You don't have to match it; out-target and out-convert in the segments you can own instead of buying share everywhere.
Assumes spend maps roughly to share of voice within the same auction — a solid directional estimate, not a billing statement.
