# Optimising a set of campaigns

You can set up a number of Optimised campaigns to compete within an Optimising Area, such that each individual only receives at most 1 per Optimisation Window (or up to 5 per Optimisation Window as of Q2 2020).

> [!NOTE]
>
> Campaign Optimisation supports the allocation of an individual across multiple campaigns over a span of time. It can reserve up to 5 campaigns per person ensuring that they are included in their "Best" campaigns. See [Multi campaign optimisation](<https://help.apteco.com/en/peoplestage/customisation/campaign-optimisation/multi-campaign-optimisation-example/index.md>).

All optimisation set-up is done via the Constraints view of the area containing the campaigns (which can be nested within sub-areas).

On the Constraints view of an area, select the **Campaign Optimisation** check box. This turns the area into what is known as an Optimising Area. An Optimising Area has a daily, weekly or monthly Optimisation Task associated with it, through which you can reserve records for the best campaign they are eligible for, as determined in the next Optimisation Window.

A number of sub-views are now available to configure the optimisation process and see the results of previous runs.

## Getting started

The Campaign Optimisation option appears when you apply an area level contact strategy. See [Area level customisation](<https://help.apteco.com/en/peoplestage/customisation/contact-strategy/area-level-customisation/index.md>).

At the area level, in Plan-Edit mode:

1. Navigate to and select the Constraints view in the top-right corner of the area view
2. Select the Campaign Optimisation check box at the bottom of the screen

You can now see and access the optimisation sub-views to configure and publish the "Optimisation Task".
