# Google Web to App

> Set up and track Google web to app campaigns with proper attribution using Linkrunner

Google web to app campaigns enable you to reach users through web search and display ads, directing them to your website where they can discover and download your app.

## Campaign Setup

### 1. Create Google Ads Campaign

* Log in to your Google Ads account
* Create a new campaign
* Configure the campaign to redirect users to your website
* Set up your targeting, bidding, and creative assets

### 2. Landing Page URL Structure

When users click on your Google ads and land on your webpage, the URL will contain important campaign tracking parameters. Here's an example of what the URL structure looks like:

```
https://www.example.com/products/your-product?variant=12345&country=US&currency=USD&utm_source=google
&gad_campaignid=12345678
&gbraid=0AAAAADDyA9sExample123456789
&gclid=Cj0KCQjw58PGBhCkARIsADbDilzExample123456789
```

### 3. Parameter Capture and App Download Link Setup

Your website must capture the following Google campaign parameters from the landing page URL:

* `gad_campaignid` - Google Ads campaign ID (required)
* `gclid` - Google Click Identifier
* `gbraid` - Google conversion tracking parameter

When users click the "Download App" button on your website, redirect them to your Linkrunner domain with these parameters:

```javascript theme={null}
// Example: Capture parameters from URL
const urlParams = new URLSearchParams(window.location.search);
const gadCampaignId = urlParams.get('gad_campaignid');
const gclid = urlParams.get('gclid');
const gbraid = urlParams.get('gbraid');

// Construct app download link
const linkrunnerDomain = 'https://your-domain.linkrunner.io';
const downloadLink = `${linkrunnerDomain}?gad_campaignid=${gadCampaignId}&gclid=${gclid}&gbraid=${gbraid}`;

// Redirect user to app store
window.location.href = downloadLink;
```

<Warning>
  The `gad_campaignid` parameter must always be passed to ensure proper campaign attribution. The parameter names must be exact matches: `gad_campaignid`, `gclid`, and `gbraid`.
</Warning>

<Note>
  Replace `your-domain.linkrunner.io` with the actual domain you've configured in your Linkrunner dashboard for app attribution.
</Note>

## Implementation Checklist

* [ ] Create Google Ads web campaign targeting your website
* [ ] Configure website to capture `gad_campaignid`, `gclid`, and `gbraid` parameters
* [ ] Set up "Download App" button to redirect with captured parameters
