Per Station Limits
Per Station Limits



Per Station Limits allows you to manage rotation of impressions at a very fine grain.

Stations within a network frequently work together to deliver the advertisements for a single advertiser. This often requires them to dedicate a certain amount of impressions or spots to that advertiser.

The Per Station Limits interface allows you to tell StreamAds exactly how to split up the pie between all stations for delivery.

Editing Per Station Limits

The first step is to open up the Per Station Limits management screen. This is done by clicking the Limits link next to each advertisement from the Campaign advertisement management screen.

IMPORTANT: Before you can set any Per Station Limits you must first target to campaign to one or more stations. This can be done from the Campaign targeting screen.

The Per Station Limits screen shows a list of stations for which you can then set the maximum limits.

You also have the ability to block stations from delivering certain advertisements in a campaign. This allows you to “sub-target” within a campaign.

Banner & Text

The following applies to Banner & Text advertisements:

  • Clicks
    This is the maximum clicks the station must deliver. A click is defined as a visitor viewing a banner or text advertisement and then clicking on it to be redirected to the advertiser's website or landing page.
  • Impressions
    The maximum number of impressions the station must deliver. Each time a visitor views a banner or text advertisement is counted as an impression.
  • Blocked
    Block this station from delivering this advertisment.


The following applies to In-stream advertisements:

  • Spot-Plays
    This is the maximum number of times an advertisement can play on the station, regardless of the number of people that heard it.
  • Impressions
    Sets the maximum number of in-stream impressions for the station. An impression is counted for EVERY listener connected to the station when the advertisement plays.
  • Blocked
    Block this station from delivering this advertisment.

Spots plays and Impressions clarified:

The difference is best explained with an example. Lets say Station A has 100 listeners connected to it when an advertisement is played on the station. StreamAds will count 1 Spot play and 100 Impressions. Say the advertisement plays again later that day, but only 50 listeners are connected, then the total Spot plays will move up to 2 and the total Impressions will be 150.


The following applies to Gateway advertisements:

  • Spot-Plays
    This should be ignored for gateway advertisements.
  • Impressions
    Sets the maximum number of gateway impressions for the station. An impression is counted each time a visitor views or hears a gateway advertisement.
  • Blocked
    Block this station from delivering this advertisment.


It is very had for a station to deliver the EXACT set limits. This is best illustrated by an example.

Lets say Station A is scheduled to deliver 1000 impressions for an in-stream advertisement and to date already delivered 990 impressions. It currently has 50 listeners connected, so playing the advertisement just one more time will put it at 1040 impressions, causing the station to over-deliver by 40 impressions (4% over-delivery).

There is also technical challenges.

Another example would be a banner set to deliver until it reaches 10 clicks. What if the station already delivered 9 clicks, but 3 visitors handled by 3 different StreamAds mirror server click on the banner at about the same time? That will cause 12 clicks to be captured.

Thus over-delivery should be expected and should indeed be showed to advertisers as FREE additonal value. Over-delivery is of course a lot better than the flip-side of the coint: Under-delivery. Keeping advertisers happy is very important to Stations, and thus very important to the StreamAds system.
