What is Google Analytics 4 (GA4)?
Event-based analytics measuring what visitors do after they arrive. Pair it with Search Console to connect rankings to engagement and conversions instead of optimizing positions blindly.

Google Search Console (GSC)
The free official view of how Google sees a site: impressions, clicks, positions, indexation, and issues. Audits join its demand data to crawl findings before prioritizing anything.
Engagement Rate
The share of sessions with meaningful interaction (time, scroll, events, conversions). GA4’s headline quality metric replacing bounce rate for most analysis.
Conversion Rate
Visitors completing a goal divided by total visitors. The metric that turns traffic into money; intent-matched pages convert multiples higher than mismatched ones at equal volume.
Impression
One appearance of a page or link in results or AI answers. Impressions without clicks diagnose snippets and intent fit; falling impressions diagnose demand or visibility loss.
Click
A visit from a result or citation. Clicks are the reality check on rankings: positions that never convert are research inputs, not assets.
Click-Through Rate (CTR)
Clicks divided by impressions. Titles, descriptions, brands, and SERP features move CTR at stable positions, which is why snippet work precedes rank-chasing on converting queries.
