How often should I refresh my LinkedIn ad creatives?

Creative fatigue happens on every platform, including LinkedIn. As professionals repeatedly see the same ad, engagement declines and costs usually increase. Watch for these warning signs: - Falling CTR - Rising CPC - Increasing frequency - Lower conversion rate For most active campaigns, refreshing creatives every 4-8 weeks is a good starting point. Refreshing doesn't always mean creating an entirely new ad. Sometimes changing the headline, hero image, opening sentence, or CTA is enough to improve performance.
