### 4.1 Analytics Readiness Website_Analytics is a single table of 62,496 rows, with 100% completeness and no validated joins, so it is structurally clean enough to start modeling immediately. No explicit dimension hierarchies were detected, which limits roll-up analysis (for example, grouping individual records into broader categories) until groupings are defined. Because the dataset is one flat table, the path forward is enrichment and schema evolution, not repairing relationships. ### 4.2 Strategic ML Opportunities | Model Type | Prediction Target | Viability | Applicable Tables | |------------|-------------------|-----------|-------------------| | Anomaly Detection | Outlier or unusual records (e.g. ENTRANCES, BOUNCE RATE (%), AVERAGE TIME ON PAGE (SECONDS)) | High | Website_Analytics | | Regression | Continuous target (e.g. ENTRANCES, BOUNCE RATE (%), AVERAGE TIME ON PAGE (SECONDS)) | High | Website_Analytics | | Recommendation | User-item affinity | High | Website_Analytics | Anomaly detection offers the best near-term return. It works directly on the existing numeric columns and can flag unusual spikes or drops in ENTRANCES, BOUNCE RATE (%) and AVERAGE TIME ON PAGE (SECONDS) without labeled history. Preparation is light: confirm the unit of each row and add a consistent time or page reference, if one exists, so "unusual" is judged against a fair baseline. The recommendation model is rated high, but the evidence does not show a user-level identifier, so confirm one exists before investing. ### 4.3 Investment Recommendations - **Pilot anomaly detection on Website_Analytics (next 30 days):** Score ENTRANCES, BOUNCE RATE (%) and AVERAGE TIME ON PAGE (SECONDS) together, and have business owners review the top-flagged records to set alert thresholds. - **Build a regression baseline (30–60 days):** Model BOUNCE RATE (%) from ENTRANCES and AVERAGE TIME ON PAGE (SECONDS) to identify which engagement patterns drive visitor drop-off. Use the 2 proposed engineered features as starting inputs. - **Define dimension groupings (60 days):** Because no hierarchies were detected, add categorical groupings, such as page type or section, as new columns in Website_Analytics. This enables segment-level comparisons and improves both models. - **Validate recommendation feasibility before committing budget:** Check whether Website_Analytics can support user-item affinity, and defer this work until a user or visitor identifier is available.
