# Datasets
### What is a dataset?
A dataset is anything that you want to measure. In the past we referred to datasets as sites, but the definition has changed to include a broader definition. \
Now, a dataset can be a single page, subset of pages, campaign landing page, sub-domain, app. etc. Think Internet of Things, or 'types of behavior'.
### Where can i find my Dataset ID or tracking pixel?
You can find all dataset ID's in the [dataset overview](https://app.leadboxer.com/datasets).
You can also get your tracking pixel by clicking on the settings icon.
{% hint style="info" %}
Note: Dataset overview is only visible and accessible for users with 'admin' permissions
{% endhint %}
### Measure all your websites
Some organisations have more than one website, LeadBoxer allows you to add multiple sites to your account, for example a specific product, region, language or event.
For a detailed [tutorial how-to add a site see here](/leadboxer/integrations/website/lead-tracking-pixel.md)
Simply add them to your account in the [dataset overview](https://app.leadboxer.com/datasets) and you will receive a unique lead pixel to install on these domains.
We also offer cross-domain tracking, please contact us for details and pricing.
