Compare digital traffic, conversion, order value, and revenue using consistent periods and denominators. A worked channel example shows how the figures reconcile and which business decisions each measure supports.
Digital analytics metrics connect traffic, customer actions, orders, and revenue using explicit definitions. A useful business review shows the counts behind each ratio and uses the same period and population throughout. The aim is to understand commercial performance, rather than to assemble the longest list of measures.
A metric needs a unit, a period, a population, and a calculation. For digital metrics and analytics, that means distinguishing visits from people, purchase sessions from orders, and merchandise revenue from cash collected.
Google Analytics defines a session as a period when a user interacts with a website or app. A session therefore is not the same unit as a customer or an order. Use the session definition attached to your exported report, and record any change before comparing periods.
| Measure | Definition for this review | What it helps the team ask |
|---|---|---|
| Sessions | Sessions in the selected reporting period | Did recorded traffic change? |
| Converted sessions | Sessions containing at least one completed purchase | Did more visits result in a purchase? |
| Completed orders | Distinct completed order identifiers | How much purchasing activity occurred? |
| Net merchandise revenue | Gross merchandise revenue less discounts and assigned refunds | What merchandise revenue remained? |
| Net order value | Net merchandise revenue divided by completed orders | How much revenue remained per order? |
| Revenue per session | Net merchandise revenue divided by sessions | How much revenue did the traffic base produce? |
These are declared business definitions. They are not interchangeable with every similarly named field in an analytics export. For example, Google's dimensions and metrics reference defines transactions as completed purchases and purchase revenue as purchase revenue less refunds; verify the specific exported field rather than inferring its scope from its name. Covirage is not affiliated with Google Analytics.
A US online business reviews September orders and the sessions in which they occurred. The traffic export provides sessions and converted sessions by channel. The order export supplies distinct orders, gross merchandise revenue, discounts, and refunds assigned to those September orders through the agreed review cutoff.
The business excludes sales tax and shipping charges from this merchandise revenue measure. Each session and order belongs to a single channel under the agreed assignment rule. Orders without a usable session link remain a separate reconciliation item; they are not silently distributed among the channels.
| Channel | Sessions | Converted sessions | Orders | Gross merchandise revenue (USD) | Discounts (USD) | Assigned refunds (USD) | Net revenue (USD) |
|---|---|---|---|---|---|---|---|
| Paid search | 10,000 | 400 | 420 | 50,400 | 2,400 | 2,000 | 46,000 |
| 5,000 | 300 | 330 | 42,900 | 2,900 | 1,000 | 39,000 | |
| Organic search | 15,000 | 450 | 450 | 54,000 | 4,000 | 3,000 | 47,000 |
| Total | 30,000 | 1,150 | 1,200 | 147,300 | 9,300 | 6,000 | 132,000 |
Net revenue is computed within every row. Paid search, for example, is 50,400 - 2,400 - 2,000 = 46,000. The company check is 147,300 - 9,300 - 6,000 = 132,000. The order-level detail must reproduce these figures before the team interprets a rate.
Session conversion rate = Converted sessions / Sessions
Orders per session = Completed orders / Sessions
Net order value = Net revenue / Completed orders
Revenue per session = Net revenue / Sessions
The following table uses only the counts and revenue above. Percentages and dollar ratios are rounded to two decimal places; calculations use unrounded values.
| Channel | Session conversion rate | Orders per session | Net order value (USD) | Revenue per session (USD) |
|---|---|---|---|---|
| Paid search | 4.00% | 4.20% | 109.52 | 4.60 |
| 6.00% | 6.60% | 118.18 | 7.80 | |
| Organic search | 3.00% | 3.00% | 104.44 | 3.13 |
| Total | 3.83% | 4.00% | 110.00 | 4.40 |
The overall conversion rate is 1,150 / 30,000 = 3.83%, not the simple average of the channel rates. That average would be (4% + 6% + 3%) / 3 = 4.33%, because it gives the smaller Email channel the same weight as Organic search.
Company net order value is 132,000 / 1,200 = $110.00. Revenue per session must also equal orders per session multiplied by net order value: 0.04 × 110 = $4.40. This identity uses the order rate, rather than the converted-session rate, because some purchase sessions contain more than one order.
Email has the highest conversion rate and revenue per session in this example. That supports checking the audience, offers, and repeat-purchase mix; it does not establish that reallocating traffic would reproduce those results. Channel populations can differ, and a channel assignment records a reporting convention rather than proof of an incremental sale.
Marketing owns the traffic and channel definitions, commerce operations owns the completed-order records, and finance owns the revenue reconciliation. The report ownership guide explains how to assign those responsibilities. Keep the agreed calculation with the report using versioned metric definitions, so a definition change does not look like business improvement.
Revenue is also not profit. Before deciding to spend more on a channel, add the relevant product and operating costs; gross profit margin explains the first margin calculation. The present table cannot establish channel profitability because it contains no cost figures.
Bring traffic and order exports with periods, channels, counts, and revenue components; Covirage maps the columns, and its tools compute and check the comparisons. The external AI model explains the result with every figure traced to its rows. Create a free Covirage account, which takes about a minute, then set up your business and bring a sample of your own data.
See metrics governance for the supporting approach to consistent business definitions.
Start with sessions, sessions with a purchase, completed orders, net revenue, conversion rate, average order value, and revenue per session. Add measures only when they answer a decision the team owns. A finance review may also need product costs and margin.
That is an orders-per-session rate. A session purchase conversion rate counts sessions with at least one purchase, divided by all sessions. The rates differ when a session produces multiple orders. Label the numerator explicitly so reviewers can interpret the comparison correctly.
It can, provided the label and period convention are explicit. A net order value measure subtracts refunds from the agreed sales base. Refunding an older order can change a current-period measure, so distinguish refunds posted during the period from refunds assigned to the original orders.
Differences can come from taxes, shipping, discounts, refunds, currency, timing, or incomplete records. Build a reconciliation using the stated definitions and source totals. Do not change a conversion denominator or revenue label merely to make two reports appear to agree.
