What is a good duration for a Terminus advertising campaign (tactic)?

Typically, a Terminus advertising campaign (tactic) spans between 30 to 90 days. However, most customers align their advertising strategy – duration and budget – with their sales cycle and the specific buying stage of their targeted accounts. 

As a general guideline, it's advisable to update your advertising creatives (swapping in new creative sets) within each tactic every 4-6 weeks. This practice becomes particularly important if you plan to run ads to the same list of accounts for an extended period.
