# Marketplace
## Viewing sites and zones available for advertising
The **Marketplace** lists all network traffic sources and available ad spots for each website, along with their respective Daily Impressions and Clicks.
***
{% hint style="info" %}
Traffic source data reflects activity from two days prior. For RTB zones to appear in the marketplace they must have a minimum of 1,000 queries.
{% endhint %}
***
## Filtering by Dimension
Use the **+Add Filter** drop-down at the top of the page to refine Marketplace results by dimension.
Available dimension filters include **Ad Format**, **Ad Placement** (e.g. Footer, NTV), **Allowed Product Category** (if enabled by the ad server), **Category** (and Sub-category), **Countries**, **Device Type**, and **Traffic Type**.
Click **Apply** to update the table. You can add multiple filters.
Click **Reset Filters** to restore the default table.
Search entries by **Site Name**, **Site ID**, or **Zone ID**. Not every ad zone has an ad placement.
***
{% hint style="info" %}
Sign in to access the **Marketplace** tab. Marketplace shows amounts in the currency you selected when you set up your account. You cannot change an existing account's currency.
{% endhint %}
***
## Column Settings
Use **Column Settings** menu, located on the right-hand side above the table, to customize the Marketplace view.
This menu allows you to toggle columns on or off, giving you full control over which data points are displayed. By tailoring the table to your needs, you can focus on the metrics that matter most and create a more relevant view of sites and zones available for advertising.
## Blacklisted Sites

### **Publishers and Sites Blacklist**:
Ad server administrators or advertisers can block a publisher or site across an advertiser account. A red warning icon appears beside a blocked site or zone. On hover of this icon, the following message is displayed: **Your campaigns are blocked for this zone.**
## Using the Marketplace tab
Use the drop-downs to filter by **Ad Type**, **Categories**, **Device Type**, and **Ad Placement**.

## 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://docs.exads.com/advertisers/marketplace.md?ask=&goal=
```
`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.
