What is Seasonality?
Predictable demand cycles by week or season. Baselines and tests must compare like-for-like periods, or every December looks like a content triumph and every January a penalty.

Baseline Period
The pre-change measurement window an experiment or update is judged against. No baseline, no causal claim: seasonality and trends must be priced in first.
Query Deserves Freshness (QDF)
Queries where recency matters (news, scores, prices, versions). QDF topics need update cadence and visible dates, not one-and-done publishing.
Editorial Calendar
The publishing schedule sequencing topics, refreshes, and seasonal pieces. Calendars turn topical maps into shipped coverage instead of backlog wishes.
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.
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.
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.
