Introduction
Many marketing teams and independent site owners conduct marketing activity evaluation based on subjective experience or scattered metrics, which often leads to problems: over-reliance on vanity metrics, misallocated budget, unclear activity value, and failure to align evaluation with real business goals.
Compared with manual, experience-driven assessment, the factor analysis + dimensionality reduction method is more objective and data-driven. It helps condense 22 complex metrics into 4 core factors, making marketing activity evaluation efficient and targeted.
Why Do We Need “Dimensionality Reduction” for Marketing Activity Evaluation?
Marketing metrics (such as conversion rate, average order value, exposure, etc.) are numerous and overlapping. For example, conversion rate and repurchase rate are highly correlated.
Analyzing each metric individually wastes time and energy while making it hard to grasp core performance.
Through factor analysis, dimensionality reduction condenses these 22 metrics into 4 core factors, making marketing activity evaluation more efficient.
4 Core Factors (Business-Oriented, No Jargon)
No need to memorize complex terms; understand core functions and goals for marketing activity evaluation:
- Revenue Factor: Focuses on profitability (AOV, repurchase rate, gross margin) — aligned with “making money.”
- Traffic Factor: Focuses on user acquisition (exposure, CTR, new users) — aligned with “attracting new customers.”
- Retention Factor: Focuses on long-term stickiness (retention rate, activity) — aligned with “building user relationships.”
- Conversion Factor: Focuses on transaction efficiency (conversion rate, order completion) — reflecting core activity effects.
Note: These 4 factors cover all key business needs, avoiding metric confusion and ensuring every marketing activity evaluation is closely linked to real scenarios.
Key Reminder: Evaluation Must Align with Business Goals
Calculating scores is not just about “numbers” but judging if needs are met in marketing activity evaluation.
- Profit improvement: Prioritize the Revenue Factor.
- User growth: Prioritize the Traffic Factor.
Do not judge value solely by scores; combine them with business goals to avoid empty evaluations.
3 Simple Steps to Calculate Activity Score (Automated)
Step 1: Determine Factor Weights
Logic: Higher factor variance = more information = higher weight.
Formula (variance contribution method):
wj = σj / Σj=1m σj
Where σj is the variance of indicator j, and wj is the weight of indicator j.
Example: Revenue variance (8.6) ÷ Total variance (16.0) = 8.6 / 16.0 = 0.5375 (53.75%). SPSS/Python output this directly.
Step 2: Calculate Single Factor Scores
Logic: Standardize metrics (eliminate unit differences) and multiply by load factors.
Standardization formula (positive indicator):
zij = (xij − min(xj)) / (max(xj) − min(xj))
Factor score formula:
Fi = Σj=1m (zij × ljk)
Where ljk is the factor loading of indicator j on factor k.
Example: Revenue score = (1.2×0.92) + (0.9×0.87) + (1.1×0.89) ≈ 2.75.
Step 3: Calculate Comprehensive Score
Formula:
Scorei = Σk=14 (Fik × wk)
Multiply each single factor score Fik by its weight wk, then sum to get the final score for your marketing activity evaluation.
