Main Time-Series Models for Marketing ROI
This section covers various time-series models designed to meet specific needs in marketing ROI analysis.
ARIMA: Autoregressive Integrated Moving Average
ARIMA is a forecasting model that uses historical data and past forecast errors to predict future outcomes. It’s particularly effective for identifying long-term sales trends and detecting anomalies in marketing performance.
The model operates through three main components:
- AutoRegressive (AR): Captures relationships between current values and their past observations.
- Integrated (I): Addresses non-stationary data by differencing it.
- Moving Average (MA): Incorporates past forecast errors to refine predictions.
While ARIMA is powerful for analyzing time-dependent data, it requires the dataset to be stationary, which can be a challenge when dealing with growth trends or seasonal variations. Additionally, tuning its parameters can be complex, often requiring statistical expertise.
In marketing, ARIMA is best suited for analyzing long-term trends or identifying unusual campaign performance. For a more intuitive approach focused on recent trends and seasonality, marketers often turn to ETS.
ETS: Exponential Smoothing
ETS, or Exponential Smoothing, specializes in capturing trends and seasonality in marketing data. Unlike ARIMA, which emphasizes autocorrelations, ETS provides a simpler way to understand how changes in trends and seasonal patterns affect ROI.
This model shines in short-term predictions, as it assigns more weight to recent observations, making it a favorite for tasks like quarterly budget planning or forecasting during specific seasons, such as back-to-school or holiday shopping. However, ETS assumes that future patterns will closely resemble past ones, making it less effective when the data is noisy or influenced by unexpected factors.
STL: Seasonal Decomposition of Time Series
STL takes a different approach by breaking time-series data into three components: seasonal patterns, underlying trends, and residual noise. It’s a flexible, non-parametric method, meaning it doesn’t rely on specific statistical assumptions, making it highly adaptable for marketing analysis.
One of STL’s strengths is its ability to handle outliers and irregular seasonal patterns. It also doesn’t require the data to be stationary, and users can fine-tune the smoothing parameters for trends and seasonality. However, STL focuses on decomposition rather than direct forecasting, so additional steps are needed to make future predictions.
Marketers often use STL to understand how seasonality impacts campaigns or to uncover hidden trends in customer acquisition that might otherwise be masked.
Prophet by Meta
Prophet, developed by Meta, is a time-series forecasting tool designed with business users in mind. It combines trends, seasonality, holidays, and error components into a single, easy-to-use framework. Its ability to handle missing data and irregular time intervals makes it particularly attractive for marketers.
Prophet is user-friendly and allows for the inclusion of external factors, such as advertising spend or economic indicators. However, it assumes that future patterns will resemble historical ones, making it less responsive to sudden changes. It’s commonly used for forecasting during major events like product launches or promotional campaigns.
Model Comparison Table
| Model | Best Use Cases | Key Strengths | Limitations |
|---|---|---|---|
| ARIMA | Long-term trend analysis, anomaly detection | Captures autocorrelations, strong forecasting | Requires stationary data, complex to tune |
| ETS | Short-term predictions, seasonal planning | Excellent for seasonality, simple to use | Assumes stable future patterns, sensitive to noise |
| STL | Seasonal impact analysis, trend isolation | Flexible, handles outliers well | Focuses on decomposition, not forecasting |
| Prophet | Event forecasting, business predictions | Handles missing data, user-friendly | Struggles with sudden changes, assumes pattern continuity |
Each of these models offers unique advantages. ARIMA is ideal for strategic, long-term planning, ETS is great for operational forecasting, STL provides detailed insights into seasonality and trends, and Prophet simplifies forecasting for teams without deep statistical knowledge.
How to Use Time-Series Analysis for Marketing ROI
Using time-series models to measure marketing ROI involves a step-by-step process that transforms raw data into meaningful insights. By following a structured approach, you can create accurate forecasts that support better business decisions.
Preparing Data for Time-Series Analysis
The quality of your data is the backbone of any successful time-series analysis. Without clean and reliable data, your forecasts are likely to mislead rather than inform. Marketing data often comes from various platforms, collected in different formats and at irregular intervals, so preparation is key.
Start by addressing missing values, which are common in marketing datasets due to tracking gaps or platform outages. You can handle these gaps using techniques like forward fill (carrying the last known value forward), backward fill (using the next available value), or interpolation (estimating values based on surrounding data points).
Next, identify and manage outliers to prevent them from distorting your analysis. Methods like the Z-score or Interquartile Range (IQR) can help flag unusual data points. For instance, a Black Friday sales spike might look like an outlier but could represent a legitimate seasonal trend. Always consider the context before removing such points.
Data transformation techniques can help uncover hidden patterns. For example, moving averages smooth out daily fluctuations to highlight broader trends, while differencing can remove long-term trends to focus on seasonal variations.
Consistency in time intervals is also critical. If you’re working with daily data, ensure every day is accounted for, even if some values are zero. When daily data is too noisy, aggregating it into weekly or monthly intervals can make analysis more manageable.
Step-by-Step Time-Series Modeling Process
Once your data is ready, the modeling process begins. Start with data visualization to identify patterns, seasonal trends, or any lingering quality issues. Visualizing your data can also help you decide which model to use.
Choosing the right model depends on your data and goals. ARIMA works well for datasets with strong autocorrelations and long-term trends, while ETS is ideal for data with clear seasonal patterns. STL decomposition is great for breaking down complex data, and Prophet is particularly useful for irregular datasets or those influenced by external factors.
To avoid overfitting, use cross-validation by testing the model on data it hasn’t seen before. For example, if you’re forecasting quarterly ROI, your test dataset should cover at least one quarter.
When evaluating model performance, metrics like Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) are essential. MAE provides an easy-to-understand average error in your data's units, while RMSE penalizes larger errors more heavily - a crucial consideration when big forecasting mistakes could impact business outcomes.
Regular cross-validation and updates ensure your forecasts remain accurate as market conditions change. Monthly or quarterly reviews allow you to retrain models with fresh data and fine-tune parameters as needed.
How to Handle Seasonality and Trends
To enhance your models, it’s important to account for seasonality and trends. These elements represent recurring patterns (like holiday shopping spikes) and long-term shifts in customer behavior or market conditions.
Time series decomposition can help by breaking data into three components: trend, seasonality, and residuals. STL decomposition, in particular, is effective for marketing data with irregular seasonal patterns.
It’s also important to distinguish between seasonality and cycles. Seasonality occurs at fixed intervals, such as monthly subscription renewals, while cycles are less predictable and often tied to broader economic factors.
For datasets with clear seasonal patterns, traditional methods like SARIMA work well. On the other hand, machine learning models are better suited for handling complex, non-linear relationships.
Incorporating external factors - like ad spend, competitor activity, or economic indicators - can improve your forecasts, especially during events like product launches or major promotions.
Techniques like moving averages can reduce short-term noise, while exponential smoothing places more emphasis on recent trends. The choice between these methods depends on whether you want to highlight recent changes or maintain an even weighting across observations.
Parameter selection is another critical step. For example, when setting seasonal decomposition parameters, you’ll need to balance smoothing trends with preserving seasonal details. Too much smoothing can obscure important signals, while too little can leave your data cluttered with noise.
Finally, ongoing monitoring and updates are essential to keep your models relevant. As consumer behavior evolves and external factors shift, regularly refreshing your models ensures your ROI forecasts stay aligned with current realities.

Business Applications and Results
Time-series models are transforming how businesses approach various marketing and operational challenges. From campaign planning to inventory management, these models deliver measurable improvements in efficiency, precision, and return on investment (ROI).
Predicting Campaign Performance and Budget Planning
Budget planning becomes far more precise with time-series forecasting. Instead of relying on intuition, businesses can now use data-driven predictions to allocate budgets more effectively. In fact, 29.3% of businesses in 2024 are leveraging AI to fine-tune their budgets. Tools like Marketing Mix Modeling (MMM) analyze historical performance data to determine the best distribution of spending across channels. These tools evaluate how different budget levels impacted past outcomes and forecast the most effective allocations for future campaigns. Companies that engage in detailed scenario planning are 20% more likely to exceed industry benchmarks.
Scenario planning allows marketers to test multiple budgeting scenarios, generating forecasts that strengthen their proposals to finance teams. By integrating data from various sources into unified dashboards, marketers gain real-time insights into performance trends. This eliminates the guesswork and fragmented information from separate platforms, giving a clear picture of how budget shifts could impact overall ROI.
This approach also helps marketers strategically time their promotional efforts for maximum impact.
Finding the Best Times for Promotions
Time-series analysis uncovers the best times to run promotions by analyzing historical data across different intervals - daily, weekly, monthly, and yearly. These insights reveal patterns that might otherwise go unnoticed, helping businesses target their audiences when they are most receptive.
For instance, a company offering DIY materials found that Sundays and Mondays showed higher buying potential. Using the Prophet model to analyze paid ad traffic, they adjusted their strategy by increasing bids on those days. Instead of spreading ad spend evenly, they concentrated their budget during peak conversion periods and scaled back during slower times. Similarly, retailers use time-series forecasting to anticipate seasonal demand shifts, ensuring that major promotional campaigns align with natural buying cycles.
Daily recalculations of forecasts ensure promotional timing stays in sync with evolving consumer behavior.
Planning Inventory for Seasonal Demand
Time-series models are equally valuable for managing inventory, especially for businesses dealing with seasonal products or fluctuating demand. By analyzing historical sales data along with external factors like weather, holidays, and economic trends, companies can predict future demand with greater precision than traditional methods.
These models excel at identifying both obvious and subtle seasonal patterns. While major shopping events like Christmas or Black Friday are well-known, time-series forecasting can also pinpoint less obvious cycles, such as mid-month purchasing spikes tied to payroll schedules or quarterly buying patterns in B2B markets. For example, a clothing retailer might analyze how weather conditions, changing fashion trends, and promotions interact to influence demand for specific items.
By integrating these forecasts with supply chain systems, businesses can adjust procurement and prepare warehouses for demand spikes. This coordination prevents stockouts during busy periods and avoids excess inventory during slower times. Additionally, it helps optimize safety stock levels - reducing carrying costs while maintaining service reliability.
Before and After Business Results
The impact of time-series models becomes clear when comparing traditional methods to data-driven approaches. These models not only improve campaign strategies and promotional timing but also deliver measurable business outcomes.
Take Dramamine, for example. By using scenario planning and predictive modeling to guide off-season marketing efforts, the company saw a 41.8% increase in incremental revenue and a 9.5% boost in overall marketing ROI.
| Metric | Before Time-Series Models | After Implementation | Improvement |
|---|---|---|---|
| Marketing ROI | Gut-based planning | Data-driven forecasting | 9.5% increase (Dramamine case) |
| Revenue Incrementality | Limited visibility | Clear measurement of additional revenue | 41.8% rise in incremental revenue |
| Budget Allocation Accuracy | Based on historical averages | Predictive modeling with scenario planning | Enhanced strategic planning effectiveness |
| Campaign Planning Efficiency | Manual analysis and guesswork | Automated forecasting and optimization | 62% lower costs with 3x more leads (content marketing) |
| Promotional Timing | Fixed schedules or reactive changes | Data-driven optimal timing | Automated bid adjustments during peak periods |
These improvements extend beyond individual campaigns to overall marketing effectiveness. Research shows that content marketing costs 62% less than traditional marketing while generating three times more leads. However, achieving these results requires the right infrastructure. Many marketers - 48% to be exact - struggle to prove the value of their campaigns due to insufficient analytical tools. Time-series models address this issue by providing clear before-and-after comparisons, helping isolate the effects of marketing activities from other business factors.
