When we ask a website’s visitors why they didn’t buy, they often report that they were confused. They hadn’t understood the words on the site. And visitors can’t buy what they can’t understand. So, with millions of dollars at stake, why are many websites confusing?

Because writing intelligibly is harder than it sounds. For example, read the following sentence from The Guardian, written by an otherwise great writer:


“Dance music aficionados can argue interminably over which of the legendary singles Frankie Knuckles produced in the late 80s – singles, you can say without fear of contradiction, that played a part in changing the face of pop music for ever – is the best.”

That sentence is free of typos and punctuation errors. And it uses sophisticated words accurately. According to many rules of English, it’s written well. Yet most people struggle to understand it, let alone work out what’s wrong with it, or how to fix it.

It’s hard to write clearly. In fact, it’s hard to find someone who can teach you how to write clearly. Schools tend to spend more time teaching pupils how to sound smart, or how to analyze Shakespearian prose, than how to be understood. Students are more likely to be told to memorize poetry than to carry out a readability test.

This is a disservice. Poetry can be life enriching, but the purpose of almost all writing is to communicate information. So if your school didn’t teach you how to write intelligibly, how can you learn?

This article contains some fantastic resources for helping you to write more clearly. It’s hard to overstate how useful they are. But first, let’s explore why so many writers are hard to understand.


Many books teach you to avoid errors. But that’s not the problem.

When most people want to improve their writing, they buy a book like Eats, Shoots & Leaves: The Zero Tolerance Approach to Punctuation,” which is about how to avoid making mistakes. Such books describe rules like the following:

  • “When there are brackets at the end of a sentence, put the period after the closing bracket (like this).”
  • “If your whole sentence is in brackets, put the period inside the closing bracket. (Like this.)”

Such rules are useful to know, but they make little difference to whether your readers understand what you are saying.


Many teachers specialize in sounding intelligent. If you follow their advice, your sales will plummet.

Many teachers encourage writing in what Richard Lanham calls the “Official Style”—a style that sounds intelligent but which is hard to read. Lanham’s book Revising Prose teaches you how to translate Official-Style sentences into plain English. It contains the following example of how Warren Buffett, the world’s most-famous investor, translated a fund prospectus into plain English:

A paragraph written in the hard-to-read Official Style (good luck with understanding it!): “Maturity and duration management decisions are made in the context of an intermediate maturity orientation. The maturity structure of the portfolio is adjusted in anticipation of cyclical interest rate changes. Such adjustments are not made in an effort to capture short-term, day-to-day movements in the market, but instead are implemented in anticipation of longer term, secular shifts in the levels of interest rates (i.e. shifts transcending and/or not inherent in the business cycle). Adjustments made to shorten portfolio maturity and duration are made to limit capital losses during periods when interest rates are expected to rise. Conversely, adjustments made to lengthen maturation for the portfolio’s maturity and duration strategy lie in analysis of the U.S. and global economies, focusing on levels of real interest rates, monetary and fiscal policy actions, and cyclical indicators.”

The same paragraph rewritten in plain English by Warren Buffett: “We will try to profit by correctly predicting future interest rates. When we have no strong opinion, we will generally hold intermediate term bonds. But when we expect a major and sustained increase in rates, we will concentrate on short-term issues. And, conversely, if we expect a major shift to lower rates, we will buy long bonds. We will focus on the big picture and won’t make moves based on short-term considerations.”

No wonder fellow investors hang on Buffett’s every word.

The Official Style is prevalent in academic literature too. On the website LOLMyThesis, graduates self-deprecatingly translate the titles of their theses from the Official Style into plain English—usually to comic effect:

  • Original title of thesis: “Environmental Enrichment and the Striatum: The influence of environment on inhibitory circuitry within the striatum of environmentally enriched animals and behavioural consequences.” Rewritten title: “Having toys and bright colours in their cages makes mice smarter in their brains!”
  • Original title of thesis: “Challenging Ritual and Exploring Deposition within the Canals of Chavín de Huántar.” Rewritten title: “Ancient Peruvians threw stuff down a drain: maybe it was ritual, probably just trash.”
  • Original title of thesis: “The Punch Brothers’ The Blind Leaving the Blind: How Heterogeneous Stylistic Techniques Provide New Interpretations of Genre.”Rewritten title: A band that detests genre classifications is just gonna have to put up with it.

The rewritten titles are facetious, and many of them omit useful information. But they also reveal a truth: The Official Style is like medieval armour. It defends you from attack, but people can no longer hear what you’re saying.

If you were to write your website in the Official Style, your conversion rate would bomb. Your visitors would leave confused. Teachers and bosses may like intelligent-sounding text, but readers prefer text that’s easy to understand.


How to write so that people will understand you.

Faced with all this bad advice, how can you learn to write well? The following tools, techniques, and books will help enormously.

A simple technique that helps you to write easy-to-read copy

The first technique for improving your writing is simple: Carry out readability tests. A readability test is simply a usability test carried out specifically on a piece of writing. We won’t go into detail about usability tests here; we described them in detail in our article “How to make millions from user testing.”

Speak first, write later

If you struggle to write clearly, you will find the following workaround useful. One of our clients, a company called Moz, had a common problem. Moz’s founder, Rand Fishkin, mentioned that in seven minutes he could persuade almost anyone to sign up. So face to face, Rand’s conversion rate was high. But he was frustrated that his website’s conversion rate was much lower.

We asked Rand to film himself saying what he would say during those seven minutes. We transcribed the video, then used the transcript as a template for the company’s new landing page. And we embedded the video itself into the page.

The new page beat the old one, having a 53% higher conversion rate during the A/B test. Rand reported that, in total, we almost tripled his company’s conversion rate. If you’d like to learn more about this project, see this detailed case study.

Many people find that their spoken English is easier to understand than their written English. If you are one of those people, try the following workflow:

  • Record yourself.
  • Get the recording transcribed. We highly recommend SpeechPad for fast, accurate transcription.
  • Edit your transcript and incorporate it into your website.
  • A/B test the new page to confirm that your changes have increased your profits.
