# Click to Native Browser

Demand-side platforms running in-app-to-mobile web campaigns on the DT Exchange track cookies, perform cross-device matching, and measure mobile web conversions. To track cookies after an ad click-through, DT opens the landing page URL in the native browser instead of the default embedded browser. In an embedded browser, DT tracks only device IDs. In a native browser, DT tracks user cookies, bounce rate, and web conversions.

## Implementing the Native Browser <a href="#h_01jndktr3yp61h0qwtxhs5463s" id="h_01jndktr3yp61h0qwtxhs5463s"></a>

DT supports the following implementation methods:&#x20;

### Method 1: Using a URL Suffix <a href="#h_01jndktr3ygaewr52av51v3781" id="h_01jndktr3ygaewr52av51v3781"></a>

1. When you run an app-to-web campaign, target the DT Exchange supply that supports opening the landing page in the native browser.
2. DT provides a custom bid request extension to flag native browser supply:

{% code title="Java" %}

```java
imp.ext.brsrclk:1
//Where [1] = native browser is forced open upon click 
```

{% endcode %}

3. Append a new URL suffix to the Click URL to force the native browser to open. \
   DT opens the landing page in the embedded browser when you do not append the URL suffix.

{% code title="HTML" %}

```html
https://ads.DSP.com/delivery/r/ajs.php?did=5bf512f8cb99bd00d942ad21dc941a00&......&FYBER_OPEN_BROWSER
