No. A booking always runs for precisely one month from the date of the installation of the Text Link or Post Link. 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; however, both parties have a monthly termination option. teliad recommends this procedure, since only long-term link settings lead to the desired success.

As long as there aren’t any drastic changes in offer quality (e.g. ranking or PageRank devaluation), Text Links and Post Links are only very rarely booked just for one or two performance periods. Booking are usually made for longer periods. The monthly system has proven to make particular sense, because it significantly reduces the risks associated with large revaluations and devaluations of the PageRank for both parties. In general, the long-term setting of backlinks is very important for Google. Frequent changes in the backlink structure (i.e. a constant, unnatural changing of backlinks) is more likely to be evaluated negatively by Google.
