# Campaigns

> The overarching unit: one hub per marketing effort, ads and funnels unified.

The **campaign** is granvl's top-level concept. Everything else hangs off it:

```
Campaign
├── Ad campaigns   (Meta / Google: the traffic you pay for)
└── Funnels        (the pages that traffic lands on)
    └── Pages
        └── Variants   (the A/B test)
```

A campaign groups the ad campaigns and funnels that belong to one marketing effort, and rolls them up into a single hub screen: blended KPIs, the ad account drill-down, funnel performance, page analytics, and session journeys in one place. Read [Funnels, pages & variants](/concepts/funnels) for the landing-page side and [Ads](/guides/ads) for the traffic side.

## Linking

Open a campaign and hit **Manage links**:

1. **Ad campaigns**: pick a platform (Meta / Google), an ad account, then the campaigns to link. You can link campaigns from multiple accounts and platforms into one hub.
2. **Funnels**: pick the funnels this campaign drives traffic to (scoped by domain).

Links are editable any time; the hub recomputes on the next load.

## What the hub shows

* **KPI cards**: CTR, CPM, cost per lead, CPC for the selected window (7d / 30d / 90d), each with a daily trend.
* **Ad accounts table**: platform → account → campaign → ad set → ad, with spend, clicks, CPC, CPM, CTR, platform-reported conversions, granvl (first-party) conversions, conv %, and **CPA**. Ad rows show the creative thumbnail; click any ad to open the full creative modal (preview, copy, delivery metrics, and for Google ads the audience targeting + per-asset performance).
* **Funnels table**: each linked funnel's spend, visitors, conversions, and conv %, expandable to pages and variants.
* **Page analytics**: sources, devices, OS, browsers, locations for the linked funnels' traffic.
* **Session journeys**: recent visitor sessions step by step, showing where they came from, what they saw, and whether they converted.

<Tip>
  "Meta conv" vs "Gra conv": the platform's own attributed conversions vs granvl's first-party count. When they disagree, trust first-party: that's what your CRM will see. CPA in the hub is always computed against first-party conversions.
