How long should I run a LinkedIn campaign before making changes?

Avoid making major changes within the first few days unless something is clearly broken. LinkedIn's algorithm needs time to gather performance data. As a general rule: • Give new campaigns at least 7–14 days. • Wait until you've accumulated a meaningful number of impressions, clicks, and conversions. • Base decisions on conversion data rather than one or two days of performance. Frequent edits can reset learning and make performance less stable.
