What effect does Title Case have on engagement of Instagram posts?

In this week’s Rear View Mirror, we’ll answer Diana’s question. What effect does Title Case have on engagement of Instagram posts?

To answer this question, we have to do a few things. First, we need to import captions/descriptions from Instagram, then identify which posts use which case. In many coding languages, you can filter and sort things by case using a technique called regular expressions, so we identified and separated out posts that were all caps (which there were quite a few, some folks really love the caps lock key), posts that were Title Case, and posts that were Sentence case or no case at all.

What did we find?

For posts which use Title Case, after controlling for account size and similar caption lengths, we see 94% more likes, 137% more views, and 144% more comments than posts which do not use Title Case.

Now, does that mean we should all run out and switch everything to Title Case? Of course not. What we have here is an association, but absolutely no causation. This only demonstrates that there IS a difference between the two.

So what’s the key takeaway? There’s some kind of association between case usage and post engagement. Your next step is to run tests of your own; this is an aggregate of thousands of Instagram accounts. It does not reflect your audience’s specific behavior and interests, so run some tests of your own. Try different cases to see how engagement changes, if at all, in your own social posting.

Methodology: Trust Insights used Facebook’s Crowdtangle software to extract 4,221,821 posts from 7,651 brands. Captions were counted by cases, separated, and then sampled into 25,000 Title Case captions and 25,000 non-Title Case captions. The dates of extraction are January 1, 2020 – February 16, 2021. The date of study is March 10, 2021.
