Scatter Plot Analysis for Marketing Channel Efficiency

This template uses scatter plot visualization to answer a critical marketing question: as you spend more on a channel, does customer acquisition cost go up, stay flat, or improve? The relationship between ad spend and CAC is rarely linear — most channels exhibit diminishing returns beyond a certain spend threshold, and finding that threshold is the key to efficient budget allocation.

Each data point represents a month-channel combination: how much was spent on Google Ads in January and what was the resulting CAC. Plotting multiple months per channel reveals the spend-efficiency curve. A channel where CAC stays flat as spend increases is scalable. A channel where CAC rises sharply has hit saturation. A channel with low spend and low CAC may be an untapped opportunity worth scaling.

The multi-channel color coding enables direct comparison. If LinkedIn has consistently lower CAC than Google Ads at the same spend level, it deserves more budget. If TikTok shows low CAC at low spend but the data is sparse, it warrants a controlled scaling experiment. Ask the AI to populate the chart with your actual channel data, add customer lifetime value as a third dimension (bubble size), or overlay budget allocation recommendations.

Frequently asked questions

Common questions

How do I add my actual marketing data?

Ask the AI: 'Update with our last 6 months of data: Google Ads ($15K/mo, $45 CAC), Facebook ($10K/mo, $38 CAC), LinkedIn ($8K/mo, $65 CAC), Email ($2K/mo, $12 CAC).' The AI will plot your data with appropriate trend lines per channel.

Can I add customer lifetime value as a third dimension?

Yes. Ask the AI to 'Add LTV as bubble size, so channels with high LTV customers appear as larger dots even if their CAC is higher.' A $65 CAC is acceptable if the LTV is $500 — the scatter plot with LTV bubbles reveals this nuance.

How do I identify diminishing returns?

Look for where a channel's trend line curves upward — the point where spending more produces proportionally less return. Ask the AI to 'Mark the inflection point on each channel's trend line where CAC begins to rise faster than spend.' This is your optimal budget per channel.

How often should I update this analysis?

Monthly is ideal. Each new data point refines the trend lines and may reveal seasonal patterns. Ask the AI to 'Add a time dimension by using lighter colors for older data points and darker colors for recent months.' This shows whether channel efficiency is improving or degrading over time.
