# Google Search By Image

Search Google results by providing an image. 

It can be used for:

* Reverse search
* Finding people, objects, product names
* Find social media 
* Related images and terms
* Identify objects on photos

## Custom data

You can add custom data to each request by using the `userData` property on the request input:

```json
{
    "startUrls": [{
        "url": "...",
        "userData": {
            "myCustom": "data"
        }
    }]
}
```

## Proxy

This actor requires proxies to run
