Understanding Campaign Metrics

Last updated: April 18, 2026

This article explains every metric available in Wevion's Ads Manager — what it means, how it's calculated, and when to use it.

Prerequisites

How It Works

Wevion displays two categories of metrics:

  1. Meta Metrics — Data reported directly by Meta (Facebook/Instagram), synced automatically from your ad accounts

  2. Postback Metrics — Conversion data sent to Wevion from your tracking system via server-to-server postbacks Postback Conversions — Server-to-Server Tracking

Some metrics are reported directly by Meta, while others are calculated by Wevion from the raw data.

Metric Reference

Delivery Metrics

These metrics tell you how many people your ads reached and how they interacted with them.

MetricDefinitionSource

Impressions

The total number of times your ads were displayed. One person can see your ad multiple times.

Meta

Reach

The number of unique people who saw your ad at least once.

Meta

Frequency

The average number of times each person saw your ad. Formula: Impressions ÷ Reach

Calculated

Clicks

The total number of clicks on your ad (includes all click types).

Meta

Inline Link Clicks

Clicks that lead to a destination (your website, app, etc.). More relevant than total clicks for performance analysis.

Meta

CTR (Click-Through Rate)

The percentage of impressions that resulted in a click. Formula: (Clicks ÷ Impressions) × 100

Calculated

Cost Metrics

These metrics help you understand how efficiently you're spending your budget.

MetricDefinitionSource

Spend

The total amount spent during the selected period.

Meta

CPC (Cost per Click)

How much each click costs on average. Formula: Spend ÷ Clicks

Calculated

CPM (Cost per Mille)

The cost per 1,000 impressions. A standard industry benchmark for ad costs. Formula: (Spend ÷ Impressions) × 1,000

Calculated

Daily Budget

The maximum amount per day allocated to this campaign or ad set. Shows the most recent value.

Meta

Lifetime Budget

The total budget allocated for the entire campaign/ad set duration. Shows the most recent value.

Meta

Bid Amount

The bid cap or cost cap amount set on the ad set (if using Bid Cap, Cost Cap, or Min ROAS strategy).

Meta

Conversion Metrics (Meta)

These metrics track actions that happen after someone interacts with your ad, as reported by Meta.

MetricDefinitionSource

Purchases

The number of purchase events tracked by your Meta Pixel or Conversions API.

Meta

Purchase Value

The total monetary value of all purchase events.

Meta

Leads

The number of lead events tracked by your Meta Pixel or Conversions API.

Meta

Add to Cart

The number of add-to-cart events tracked on your website.

Meta

Conversions

The total number of conversion events (includes purchases, leads, and other conversion types).

Meta

Cost per Purchase

Average cost to acquire one purchase. Formula: Spend ÷ Purchases

Calculated

Cost per Lead

Average cost to acquire one lead. Formula: Spend ÷ Leads

Calculated

Cost per Add to Cart

Average cost per add-to-cart event. Formula: Spend ÷ Add to Cart

Calculated

Profitability Metrics (Meta-based)

These metrics calculate your return on ad spend using Meta's reported conversion values.

MetricDefinitionSource

Profit (Meta)

Your net profit based on Meta conversion data. Formula: Purchase Value − Spend

Calculated

ROI (Meta)

Return on Investment percentage. Formula: ((Purchase Value − Spend) ÷ Spend) × 100

Calculated

ROAS

Return on Ad Spend. Shows as a multiplier. Formula: Purchase Value ÷ Spend. Displayed as "Nx" (e.g., 3.5x means €3.50 revenue per €1 spent).

Calculated

AOV (Average Order Value)

Average revenue per purchase. Formula: Purchase Value ÷ Purchases

Calculated

Postback Metrics

These metrics come from your external tracking system via server-to-server postbacks. They provide an independent view of conversions, separate from Meta's reporting.

MetricDefinitionSource

PB Conversions

Number of conversions reported by your tracking system.

Postback

PB Revenue

Total revenue reported by your tracking system.

Postback

PB Profit

Net profit based on postback data. Formula: PB Revenue − Spend

Calculated

PB ROI

Return on Investment based on postback data. Formula: ((PB Revenue − Spend) ÷ Spend) × 100

Calculated

Why both Meta and Postback metrics? Meta's reporting uses its own attribution model, which may differ from your tracking system. Comparing both gives you a fuller picture of your true performance. Postback Conversions — Server-to-Server Tracking

Step-by-Step Guide

Reading the Summary Bar

At the top of the Ads Manager, the summary bar shows aggregated totals across all campaigns matching your current filters:

These totals represent ALL matching items, not just the currently visible page. This is important — if you have 200 campaigns but only see 50 on screen, the summary reflects all 200.

Comparing Metrics

To evaluate campaign health quickly, focus on these key metric combinations:

For e-commerce (Sales objective):

  • ROAS > 1x means you're profitable (before operating costs)

  • Cost per Purchase tells you acquisition cost

  • AOV helps you understand average ticket size

For lead generation (Leads objective):

  • Cost per Lead is your primary efficiency metric

  • CTR indicates creative quality

  • Frequency > 3-4 may signal audience fatigue

For traffic:

  • CPC shows content cost efficiency

  • CTR measures creative relevance

  • Inline Link Clicks (not total clicks) for true traffic volume

For awareness:

  • CPM is the key efficiency metric

  • Reach tells you audience size reached

  • Frequency should stay controlled (usually < 3)

Understanding Calculated vs Direct Metrics

Metrics marked "Calculated" are computed by Wevion from raw Meta data:

  • They update whenever the underlying data is refreshed

  • They respect your selected currency setting (all monetary values are converted)

  • They respect your selected timezone setting (daily aggregation boundaries shift)

Frequently Asked Questions

Q: Why is my ROAS showing as "—" or zero? A: ROAS requires both Spend and Purchase Value to be greater than zero. If Meta hasn't tracked any purchases (or your pixel isn't firing purchase events), ROAS will show as zero or empty.

Q: Why do Meta conversions and Postback conversions differ? A: This is normal and expected. Meta uses its own attribution model (view-through + click-through with configurable windows). Your tracking system likely uses a different attribution model (usually last-click). Discrepancies of 10-30% are common. [See: ART-218]

Q: What does "Frequency: 5.2" mean? A: Each person in your audience has seen your ad an average of 5.2 times. High frequency (>3-4) can indicate audience fatigue — consider expanding your audience or refreshing your creatives.

Q: Are these metrics real-time? A: No. Metrics are synced from Meta periodically (approximately every 15 minutes). Meta itself reports data with some delay (usually 15-30 minutes). For the most current numbers, use the manual refresh option.

Q: Why do I see "Unattributed Conversions" in my postback totals? A: Unattributed conversions are postback events where the campaign, ad set, or ad ID couldn't be matched to a known entity. This can happen if the tracking parameters weren't passed correctly. [See: ART-218]

Q: Can I customize which columns are visible? A: Yes. Use the column visibility toggle in the table header to show or hide specific metrics based on your workflow needs.
