Impression
An impression is counted each time a webpage appears in search results, regardless of whether the user clicks on it. It measures search visibility — how often your content is shown to potential visitors.

Why It Matters
Impressions are a foundational SEO metric. CTR (Click-Through Rate) is calculated as clicks divided by impressions, so understanding impressions is essential for interpreting CTR correctly. Rising impressions mean growing search visibility. High impressions with low clicks signal that title tags or meta descriptions need improvement.
How Google Search Console Counts Impressions
Google Search Console counts impressions differently depending on result type:
Standard blue links: All results on a loaded SERP page count as impressions, regardless of whether the user scrolls to see them.
Carousel/scroll results: An impression is counted only when the user scrolls the carousel and the result appears on screen.
AI Overview/AI Mode: As of 2026, if the same URL appears in both AI Overview and standard results, Google Search Console counts it as one impression.

| Metric | Definition | Relationship |
|---|---|---|
| Impressions | Times shown in search results | Base metric |
| Clicks | Times actually clicked | Subset of impressions |
| CTR | Clicks ÷ Impressions × 100 | Click efficiency per impression |
| Average Position | Mean ranking in results | Higher rank → more impressions |
Interpreting Impression Data
- Impressions up + clicks flat → title/description needs improvement (CTR issue)
- Impressions down + rank stable → overall search volume for that keyword may be declining
- Impression spike → new keyword ranking gained or seasonal demand increase
- Comparing data across September 2025 → when Google dropped support for the num=100 parameter (100 results per page) on September 12–14, 2025, desktop impressions plunged and average position appeared to "improve" for many properties. This was a measurement artifact — impressions previously generated by rank-tracking bots disappeared — not an actual ranking change, so treat period comparisons spanning that date with caution (rank-tracking tools were affected the same way)
- Impressions represent potential traffic, not actual traffic — impressions without clicks have limited business value
