You don't need expensive analytics software to know whether your marketing spend is working. A simple, consistently updated spreadsheet covers what most small businesses genuinely need.
Four columns are enough to start: channel, monthly spend, number of resulting customers, and revenue generated from those customers. From these, cost per customer and return per dollar spent are simple calculations.
Perfect multi-touch attribution is genuinely difficult even for large companies with dedicated analytics teams. For a small business, simply asking new customers how they found you, or using distinct phone numbers or promo codes per channel, is accurate enough to guide real budget decisions.
Daily fluctuations are mostly noise. A monthly review is frequent enough to catch a channel that's genuinely underperforming its expected range, without overreacting to short-term variance.
The point of tracking isn't the spreadsheet itself — it's using the data to shift next month's budget away from underperforming channels and toward the ones with a proven return, on a regular cadence.
Want a starting benchmark to track your actual results against? Our free Business Marketing Blueprint Generator gives you an expected channel allocation and cost range to compare your real numbers to.
No — a simple spreadsheet with a few consistent columns is enough for most small businesses to track spend and return by channel.
Channel, monthly spend, number of resulting customers, and revenue from those customers are the essential minimum to calculate ROI per channel.
Monthly is a reasonable cadence — frequent enough to catch problems, infrequent enough to avoid reacting to short-term noise.
