One shared advertising system

BAPC Ads

Every BAPC app shows BAPC's own promotions from one place: three spots on every page (top, middle and bottom), one owner-only admin, and no personal data in any event.

See the demo page Open the admin

Add BAPC Ads to a page

Load the script once per page:

<script src="https://ads.bapc.app/ads.js" defer></script>

Put the three spots where they belong:

<bapc-ad app="overs" page="home" spot="top"></bapc-ad>
<bapc-ad app="overs" page="home" spot="middle"></bapc-ad>
<bapc-ad app="overs" page="home" spot="bottom"></bapc-ad>

Allow BAPC Ads in the page's Content-Security-Policy (no style change needed):

script-src https://ads.bapc.app; connect-src https://ads.bapc.app;
img-src https://ads.bapc.app; media-src https://ads.bapc.app

Tags added later (single-page apps) and changed attributes work. If anything fails, the spot hides itself.

How it counts

An impression counts only when at least half the card is visible for one second in a visible tab.
Clicks, button clicks, dismissals and video quarters are counted once per delivery.
Tracked links work for 30 minutes; paused, ended or removed ads never redirect.
Only approved HTTPS destinations can be advertised.
Screens re-check every 30 seconds, so switching an ad or a spot off takes effect quickly.
