# Introduction # {#intro}
*This section is non-normative.*
The Protected Audience API facilitates selecting an advertisement to display to a user based on a
previous interaction with the advertiser or advertising network.
When a user's interactions with an advertiser indicate an interest in something, the advertiser can
ask the browser to record this interest on-device by calling
{{Window/navigator}}.{{Navigator/joinAdInterestGroup()}}. Later, when a website wants to select an
advertisement to show to the user, the website can call
{{Window/navigator}}.{{Navigator/runAdAuction()}} to ask the browser to conduct an
<dfn>auction</dfn> where each of these on-device recorded interests are given the chance to
calculate a bid to display their advertisement.
<h2 id="joining-interest-groups">Joining Interest Groups</h2>
*This first introductory paragraph is non-normative.*
When a user's interactions with a website indicate that the user may have a particular interest, an
advertiser or someone working on behalf of the advertiser (e.g. a demand side platform, DSP) can ask
the user's browser to record this interest on-device by calling
{{Window/navigator}}.{{Navigator/joinAdInterestGroup()}}. This indicates an intent to display an
advertisement relevant to this interest to this user in the future. The [=user agent=] has an
<dfn>interest group set</dfn>, a [=list=] of [=interest groups=] in which
[=interest group/owner=] / [=interest group/name=] pairs are unique.

{{AuctionAdInterestGroup}} is used by {{Window/navigator}}.{{Navigator/joinAdInterestGroup()}}, and
when an interest group is stored to [=interest group set=].
`priority` and `prioritySignalsOverrides` are not passed to `generateBid()` because they can be
modified by `generatedBid()` calls, so could theoretically be used to create a cross-site profile of
a user accessible to `generateBid()` methods, otherwise.

<h3 id="interest-group-storage-maintenance">Interest Group Storage Maintenance</h3>
There is a job that periodically [=performs storage maintenance=] on the [=user agent=]'s
[=interest group set=]. It performs operations such as [=list/removing=] expired or excess
[=interest groups=]. An [=interest group set=] must respect the following limits. Implementations
may define their own values for the below constants, however we supply the below values as a
starting point, inspired by what the initial implementation of this specification uses:
* <dfn>Interest group set max owners</dfn> is 1000, which defines the max number of
[=interest group/owners=] in the [=user agent=]'s [=interest group set=].
* <dfn>Max regular interest groups per owner</dfn> is 2000, which defines the max number of
[=regular interest groups=] in the [=user agent=]'s [=interest group set=] for an
[=interest group/owner=].
* <dfn>Max negative interest groups per owner</dfn> is 20000, which defines the max number of
[=negative interest groups=] in the [=user agent=]'s [=interest group set=] for an
[=interest group/owner=].
* <dfn>Max interest groups total size per owner</dfn> is <code>10\*1024\*1024</code>, which
defines the max total [=interest group/estimated size|sizes=] of [=interest groups=] in the
