|Ban Man Pro version 2.1 and
higher provides a frequency cap option. In order to use this
functionality you must turn on the feature in the preferences. For
performance reasons do not turn this feature on unless you are using
it. At times when you are not using the feature it should be
disabled in the preferences. The feature is found at the end of the
"Other Information" section of the preferences. Check
"Support Frequency Cap using Session Variables" in order to
enable this feature.
This feature uses session variables
to track the number of times each banner is viewed. For this reason
you might choose to never use this feature as sessions can cause a
performance decrease in Internet Information Server. Also, if the
user is has cookies disabled the server may not be able to maintain
session state in which case the user may exceed the frequency cap.
Once the feature has been turned on, you
will notice a Frequency Cap field when adding or editing a campaign.
The limit for a particular campaign is entered in this box. For
example, entering a value of 3 will limit this particular campaign to 3
impressions per visitor per session. If a visitor leaves your site
and comes back 2 hours later, a new session is started and the frequency
cap starts over again. Entering a value of zero means the campaign
is not capped and will display an unlimited number based on the weightings
of the campaign.
Note: For performance reasons, the
frequency cap feature had to be limited to 5 campaigns. Therefore,
at any given time you should not use a cap on more than 5 campaigns.
We also recommend that high-traffic
sites DO NOT use this feature. You might also considering charging
advertisers a premium for this feature.
