In this fast-paced world, you have to make your message count. Don’t get caught up in trying to say everything in one post or tweet. Aim to make your content as long as it takes to convey the message, and no longer.
Tweets shorter than 100 characters have a 17% higher engagement role.
Posts with 40 characters receive 86% more engagement than posts with a higher character count.
If your Google+ headline can’t be contained in one line, your first sentence must be gripping teaser to get people to read more.
Opening paragraphs with larger fonts and fewer characters per line make it easier for the reader to focus and jump quickly from one line to the next.
Email Subject Lines
Subject lines containing 28-39 characters get an open rate of 12.2% and click rate of 4% on average.
Only the first 3 words and the last 3 words of a headline tend to be read. Rather than worrying about length, you should focus on making every word count.
Overall, 74% of posts that are read are under 3 minutes long and 94% are under 6 minutes long.
The most popular videos are pretty short. After analysing the length of the top 50 YouTube videos, the average length was 2 minutes 54 seconds.
The average Podcast listener stays connected for 22 minutes on average. Studies show students zone out after 15-20 minutes of lecture time. After 20 minutes, attention and retention rates crash.
