We are often asked when the best time to post, but did you know the length of your post can also affect performance? Recent evidence has shown that the length of a post can have the same kind of impact as publishing time. While you know the general rule of “the fewest of words” possible, our friends at Ad Week have created a great infographic that shows how long posts should really be!

Here are the highlights:

  • Facebook should be less than 40 characters.   This last sentence was 43 characters – make it short. These posts have 86% higher engagement
  • While Twitter gives you 140 characters, you should only use 100. Posts less than 100 get 18% higher engagement.
  • Blog headlines – People only read the first 3 and last 3, so don’t make it longer than 6.
  • LinkedIn posts seem to have different rules depending on the audience. For real estate professionals connecting with consumers, the ideal length is 21 – 21 words.

While it is not specifically related to social media, there are also a few interesting facts about email subject length – under 40 characters, and how to compose your opening paragraph – with a larger font and fewer words per line.

If you have ever type the perfect tweet and then realize it’s too many characters, you understand it is hard to match a concept to a specific length. It is hard to cut characters, and sometimes cutting characters means readdressing your delivery as well. As the quote often attributable to Mark Twain goes, ‘I didn’t have time to write a short letter, so I wrote a long one instead.’ Well according to this research, it looks like it is worth it to take the time to do it right.
