The display duration of each advertisement is automatically controlled without intervention by the webmaster.
If an advertiser does nothing after placing an ad, then it is handled in three stages as follows:
Stage 1 - The ad is displayed on the public ads list for 2 months from the date of posting.
Stage 2 - The ad is removed from the public ad list, but is held on the system for 2 months.
Stage 3 - The ad is deleted.
This works in practice as follows:
Stage 1 - 2 Months Duration
When an ad is created it is designated as Active and is displayed for 2 months.
Stage 2 - 2 Months Duration
Then the system automatically makes the ad Inactive and it is no longer displayed on the public ads list.
During this 2 month period the advertiser can request the webmaster to reset the ad status to Active and it is again displayed for a further 2 months. An ad can be displayed indefinitely by this process.
If an advertiser does nothing during Stage 2 - the 2 months when an ad is Inactive - then at the end of this period the system automatically deletes the ad.
