# Vanity Metrics vs. Incremental Sales

In the context of RMNs, **vanity metrics** refer to surface-level advertising statistics like *impressions* and basic *clickthrough rates (CTRs)* that do not directly connect to actual product sales. Typical retailers rely on these metrics to justify asking for increased spending, despite offering no data to validate past performance. Suppliers view investments based solely on these metrics as a 'black box with a bill' (see [[quote-black-box-with-a-bill]]). Leading RMNs abandon vanity metrics in favor of quantifying **incremental sales** — the discipline of [[concept-performance-accountability]], operationalized via [[action-link-ads-to-transactions]].

**Counter-perspective (enrichment).** 'Vanity metrics' are not always useless. Impressions and CTRs are weak proxies for sales but can still serve as operational diagnostics when used alongside incrementality, reach, frequency, and audience-quality metrics. The sharper critique is not that they are meaningless, but that they are *insufficient as the sole basis for commercial claims*.
