Key takeaways

  • Journalists will read the headline and possibly the first line of a press release. Clench cites the journalism school rule: a press release intro should be no longer than 30 words.
  • Inconsistent messaging is one of the first things Harpswood tests with new clients. Ask two co-founders to describe their business separately - they will often give completely different answers.
  • One or two well-placed statistics land better than a long list. If someone on the Today programme delivers seven or eight stats in a row, even an attentive listener gets lost.
  • Founders tend to repeat their key message far less than they should. By the time you are sick of saying it, most of your audience has only heard it once.
  • Investors use quick Google searches as part of due diligence. A company that has deliberately avoided PR can find investors asking: why have I not heard of you?
  • Personal angles get more coverage than business angles. A pitch leading with "my business has no HR department" outperformed any pitch about Octopus Energy's product or growth.
  • Strong images consistently determine whether a story gets picked up and where it is placed. An eye-catching photo in the right location will often do more than the press release.
  • Harpswood's banned word list includes: utilise, leverage, reach out, circling back, and going forward. Smith and Clench argue these signal corporate register and cause journalists to disengage immediately.
  • Philip Collins, who wrote speeches for Tony Blair, identifies three things that produce clarity in writing: simplicity, precision, and brevity. Clench applies these directly to press releases and client messaging
