What is Data Sampling?
Analytics estimating from a subset when full computation is expensive. Sampling distorts long-tail SEO analysis first, so verify unsampled or BigQuery exports for content decisions.

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.
Regex Filtering in GSC
Using regular expressions in Search Console to slice queries and pages by pattern. The fastest route to template-level insights: one filter exposes every faceted or localized variant at once.
Log File Analysis
Reading server logs to see which URLs bots actually fetch, how often, and with what status. Logs reveal crawl waste and orphaned discovery that crawler simulations can only guess at.
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.
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.
