When measuring brand lift on LinkedIn, test results and statistical strength can continue to fluctuate for how many days after your scheduled end date?

LinkedIn's Brand Lift Studies are designed to provide robust insights into how your campaigns impact brand metrics. While a campaign might officially end, the platform continues to process and analyze data for a period afterward to ensure the statistical significance and stability of the results. This post-campaign data collection and analysis phase can extend for up to 15 days. This allows for a more complete picture of the brand lift, accounting for any delayed responses or data processing, and ultimately provides more reliable and actionable insights. Shorter periods like 5 or 10 days might not capture the full impact, while 20 days is longer than the typical processing window.
