| Field | Detail |
|---|---|
| Definition | Click-through rate measures the percentage of impressions that produce a click. |
| Formula | Clicks / Impressions |
| Why it matters | CTR is often an early signal of message match, creative resonance, and search-intent alignment. |
| Good benchmark context | CTR should be benchmarked by channel, placement, objective, and audience because a good paid-search CTR is very different from a good display CTR. |
Glossary entries should explain where interpretation goes wrong, not just repeat a formula.
| Common mistake |
|---|
| Comparing CTR across channels without considering intent and placement. |
| Treating a higher CTR as universally better even when traffic quality is weak. |
| Ignoring the relationship between CTR and downstream conversion rate. |
