According to LinkedIn, how many seconds do you have to capture someone's attention as they scroll through the LinkedIn feed?

LinkedIn creative guidance emphasizes that feed attention is limited and decisions happen quickly while members scroll. Strong imagery should communicate the main idea immediately before the user moves past the post. Copy should be concise and paired with a clear visual so the message can be understood at a glance. This is why LinkedIn recommends designing creative for fast recognition, mobile viewing, and one focused message.
