# Placement Limits and Guidelines

This section explains the limits applied to placements and why they exist. These rules are designed to ensure optimal performance, accurate learning, and effective monetization.

### Summary of limits and best practices

| Rule                         | Limit / Threshold                        | What happens if exceeded?                      |
| ---------------------------- | ---------------------------------------- | ---------------------------------------------- |
| Maximum number of placements | 10 per site (total, across all requests) | Extra placements are ignored and not monetized |
| Maximum placement length     | 50 characters                            | placements may be rejected or ignored          |
| Low-traffic placements       | Fewer than 1500 adcalls per day          | No meaningful value                            |

#### **Why it matters?**

Too many placements slow down learning and optimization and low-volume placements reduce overall performance.

#### **Placement Naming Suggestions:**

* Banner
  * `banner_top`
  * `banner_middle`
  * `banner_bottom`
  * `banner_left`
  * `banner_right`
  * `banner_sticky_top`
  * `banner_sticky_bottom`
* Interstitial
  * `interstitial_page_load`
  * `interstitial_exit`
  * `interstitial_pause`
* Video
  * `video_instream`
  * `video_outstream`
  * `video_rewarded`
  * `video_midroll`
* Native
  * `native_feed`
  * `native_article`
  * `native_recommendation`

## 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://adagio-io.gitbook.io/adagio-documentation/operations-and-support/standards-and-compliance/placement-limits-and-guidelines.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.
