# Set the right subcategory for your traffic

An important aspect about traffic monetization is **category labeling**. Advertisers will set up higher bids on specific niches of traffic that will yield them better results, so in order to increase your CPMs it is important that you present your traffic under the right category.

There are three different ways to label your traffic:

* Through your **ad zone settings**.

  When you [create a zone](/publishers/sites-and-zones/create-zone.md), you can determine the specific subcategory of the traffic that will be sent through the zone.

  ![zone\_subcategory](/files/5480939bc1861a0fa16b2ba04f53355056b78d60)
* Through your **tags**.

  When you put the ad zone into your site, you can also add [specific tags in the code](/publishers/sites-and-zones/using-tags.md) in order to narrow down the type of content you offer. If you use tags that match one of the available subcategories, your traffic will be associated to that subcategory. This way, you can dynamically specify the subcategory of your website without having to limit your ad zone to just that subcategory.

  You can find some suggestions on how to achieve this in [our blog](https://www.exoclick.com/publishers-how-to-automate-keyword-extraction-from-meta-tags/).
* Through **URL detection matches**.

  The ad zone code is able to detect some terms from the URL where it is located. Some of these keywords are associated to one or several subcategories we have on the platform. If there is a match, we will label the traffic under the corresponding subcategory.

These ways of determining the subcategory are organized from most to least important, meaning that the tags in your ad zone will have priority over the URL detection and **the subcategory from your ad zone settings in the Admin Panel will have priority over anything else**.

## 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.exoclick.com/publishers/publishers-faq/optimisation-tips/determine-category.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.
