Is there an overall rule to what length a post should be? The 140 character limit for Twitter may seem like a clear guideline, but does it mean you should aim for as close to the max as possible? The answer may surprise you:
The following excerpt is by Kevan Lee, content crafter from Buffer, and was originally posted on Social Media Today. We've highlighted just a few of Lee's findings, so be sure to check out the comprehensive article.
Every so often when I'm tweeting or emailing, I'll think: Should I really be writing so much?
I tend to get carried away. And for the times that I do, it sure would be nice to know if all this extra typing is hurting or helping my cause. I want to stand out on social media, but I want to do it in the right way.
Curious, I dug around and found some answers for the ideal lengths of tweets and titles and everything in between. Many of these could have been answered with "it depends," but where's the fun in that? Solid research exists to show the value of writing, tweeting, and posting at certain lengths.
The ideal length of a tweet is 100 characters
Whom should you trust when it comes to advice on the ideal length of a tweet? How about Twitter itself?
Twitter's best practices reference research by Buddy Media about tweet length: 100 characters is the engagement sweet spot for a tweet.
Creativity loves constraints and simplicity is at our core. Tweets are limited to 140 characters so they can be consumed easily anywhere, even via mobile text messages. There’s no magical length for a Tweet, but a recent report by Buddy Media revealed that Tweets shorter than 100 characters get a 17% higher engagement rate.
Analysis saw a spike in retweets among those in the 71-100 character range---so-called "medium" length tweets. These medium tweets have enough characters for the original poster to say something of value and for the person retweeting to add commentary as well.
The ideal length of a Facebook post is less than 40 characters
Forty characters is not much at all. (The sentence I just wrote is 35 characters.)
But 40 is the magic number that Jeff Bullas found was most effective in his study of retail brands on Facebook. He measured engagement of posts, defined by "like" rate and comment rate, and the ultra-short 40-character posts received 86 percent higher engagement than others.
The 40-character group also represented the smallest statistical set in the study (only 5 percent of all posts qualified at this length), so best practices on Facebook also include the next most popular set: Posts with 80 characters or fewer received 66 percent higher engagement.
Many different studies over the years have confirmed that shorter posts are better on Facebook. One such study by BlitzLocal looked at nearly 120 billion Facebook impressions and found that performance tailed off as posts grew longer. Their particular data found significant advantages to question posts between 100 to 119 characters.
The ideal length of a blog post is 7 minutes, 1,600 words
When measuring the content that performs best on their site, Medium focuses not on clicks but on attention. How long do readers stick with an article?
In this sense, an ideal blog post would be one that people read. And Medium's research on this front says that the ideal blog post is seven minutes long.
To arrive at this number, Medium measured the average total seconds spent on each post and compared this to the post length. All Medium posts are marked with a time signature for how long the read should be. After adjusting their analysis for a glut of shorter posts (overall, 74% of posts are under 3 minutes long and 94% are under 6 minutes long), they came to their conclusion:
And there we have it: the average total seconds rises for longer posts, peaks at 7 minutes, and then declines.
And in terms of word count, a 7-minute read comes in around 1,600 words.
