Stop writing all-caps headlines, a CRO expert says

A conversion-rate-optimization specialist at Practical Ecommerce says all-caps headlines are hurting click-through rates and making brands look desperate. The advice is simple: write headlines like you talk — sentence case, not shouting at the reader.

The writer tested this on their own site. Switching from ALL CAPS to sentence case lifted click-through by 4.2 percent over 90 days. It's not a flashy number, but it's real. No fancy tools, no A/B testing platforms — just a rule of thumb and a spreadsheet.

The argument is about respect. All-caps reads like yelling. It signals the writer is trying to grab attention but doesn't trust the words to do the work. For a shop owner posting a sale, the auntie posting on Facebook, or a small business running an ad — plain English reads easier, faster, and feels more honest.

Why this matters for us: the brands competing for our attention are still shouting. Writing like we talk — in sentence case — is a small shift that cuts through the noise and makes the message land.
