# bol ads preview

The Preview tab displays the state of your ads after running the bol. Ads Channel. This feature lets you preview your changes without applying them to bol. Ads, so you can review and refine your setup before creating the actual Ads on bol.

Depending on your campaign type, the data in the preview tab is organized into:

* Campaigns
* Ad groups
* Ads
* Keywords (only manual targeting campaigns)
* Negative keywords

{% hint style="info" %}
Note I: Running "reload preview" refreshes all campaign generators. We fetch information from bol to complete this process. Although this is usually fast, it could take up to a few minutes.
{% endhint %}

{% hint style="info" %}
Note II: The preview will not take into account the automation rules that will be applied.

### Filters

You can filter a selected entity (campaign or ad group) by clicking on the name of the entity in the preview overview. Clicking the entity name shows the child-entity page filtered on that specific entity. For example, if you click on a campaign, you go to the ad group view filtered by that campaign.

You can use the search box to enter a text filter that will match any of the entities.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://helpcenter.channable.com/list-advertise/bol/how-to-set-up-bol-ads-campaigns/bol-ads-preview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
