Example: “Based on current growth, our café’s cold brew ad will likely hit 100,000 views in the next 2 weeks, with about 1,200 conversions.”
This uses existing patterns to forecast.

Example: “Since TikTok ads are converting at 3× the rate of Instagram, we should reallocate 60% of our ad budget to TikTok next month.”
This gives a clear actionable recommendation.

A café runs a summer campaign. Using time series, they spot sales spikes in December. Cohort analysis shows December’s new customers stick around longer than January’s. Sentiment analysis of TikTok comments reveals people love the product but complain about price. Cluster analysis groups customers into students, professionals, and families — each with different needs. Together, these analyses guide where to spend ad money and how to adjust messaging.

A local café launches a summer campaign for its new cold brew coffee, posting across Instagram and TikTok.

Descriptive analysis shows that TikTok ads generated 50,000 impressions and 3,200 clicks, while Instagram only delivered 12,000 impressions and 600 clicks.
Diagnostic analysis reveals why: engagement on Instagram dropped after switching from video posts to static images, while TikTok’s algorithm boosted the video ads.
Time series analysis shows that engagement spikes on weekends and in the hottest weeks of December, when demand for iced coffee is naturally higher.
Cohort analysis compares followers gained in December vs January: December’s new followers are twice as likely to come back for repeat purchases.
Sentiment analysis of TikTok comments reveals 70% are positive (“refreshing, perfect for summer”) but 15% complain about the $5.95 price point.
Cluster analysis sorts customers into three groups:
1. Students buying small iced coffees daily,
2. Professionals grabbing large coffees on weekday mornings,
3. Families buying novelty drinks on weekends.
