A booking always runs for precisely one month from the date of the installation of the link ("green status"). Buyers can set their booking so that its period of validity is automatically extended for a further month 14 days before the end of the current performance period. Since only long-term link settings lead to the desired success, teliad recommends this procedure.

As long as there aren’t any drastic changes in offer quality (e.g. ranking or PageRank devaluation), Text Links and Post Links very rarely are only booked for just one or two performance periods. Booking are usually made for longer periods. Buyers can set their booking so that its period of validity is automatically extended for a further month two weeks before the end of the current performance period. Due to this setting, bookings run for an unlimited period. Both parties have a monthly termination option here, which has proven to make particular sense, because the risks associated with large changes of the offer data can be significantly reduced for both parties as a result.

In general, it is very important for Google that backlinks are set for long periods. Frequent changes in the backlink structure, i.e. a constant, unnatural changing of backlinks is more likely to be rated negatively by Google.
