Your team has created, socialized, and measured content in just about every possible way … except for one of the most important metrics: how your audience is engaging with the words.
You want visitors to find information, stay engaged, or complete a task. But once readers’ eyes hit the words on the page, if it takes too much effort, their interaction falls off and you have churn. You know this anecdotally. Yet most don’t measure it scientifically.
Which of the thousands if not millions of words on a website are helping or hurting? What content is too dense or confusing?
Content teams work hard to create compelling content, but they have a natural blind spot. They’re too close to their creations – the blogs, thought leadership, and marketing pieces – to see them through the audience’s eyes.
AI tools can benchmark content understanding
Now, with advances in natural language processing and artificial intelligence, a new breed of technology can test content for readability and clarity, which go to the heart of user experience and engagement. It can move organizations from a subjective approach, often fraught with editorial friction, to an objective, metric-based approach.
In this article I look at how to test for readability across your organization. For CMOs and chief content officers who want more engaging content, you now have ways to measure and benchmark clarity across the organization. And these tools can also help individual writers and creators produce better quality content.
Let’s define readability and clarity
Content clarity is the user experience of how difficult or easy it is to read text. Why is that important? We know from neuroscience that processing words places a far greater cognitive load on the brain than images. Plus, attention spans are shorter, meaning visitors have lower tolerance for confusion.
Fortunately, there are several widely used measures. The Flesch Reading Ease Index, created by Rudolf Flesch in the 1950s, calculates the average syllable per word and the density of long sentences and assigns a readability score – the higher the number, the easier content is to read.
The Flesch-Kincaid measure, derived from the index, scores readability at grade level, approximating the number of years of education required to easily understand content (though with this tool, a lower score means higher readability). The U.S. Navy developed the Flesch-Kincaid measure in the 1970s to ensure that soldiers under stress in the field could easily understand written instructions in their manuals. While today’s audiences most likely aren’t in combat, they do face the stresses of information overload and too little time.
Your readers are checking out and churning
Research shows that the average U.S. citizen reads at a seventh- to eighth-grade level – and it’s not simply a problem of low academic achievement. Some studies show even highly educated people disengage rather than spend the mental energy to unpack dense, complicated prose. Josh Bernoff, author and a contributor to the Harvard Business Review, surveyed 550 businesspeople in 2016. As many as 81% said poorly written content wasted too much of their time.
That’s one reason Reader’s Digest and Time magazine are successful. Reader’s Digest has a readability index of about 65 and Time scores about 52. Give people the choice between reading something at that level versus run-on sentences of 40 or 50 words with several competing ideas, it’s clear which they’ll prefer.
What is good readability?
There’s no one size fits all, but the gold standard of readability for business communication is grade eight or lower.
You should limit long sentences and passive voice to 5% or less of the total content. Active voice rather than passive makes it clearer who needs to do what. By shortening sentences and using active voice, you can make even technical subject matter more readable and engaging without any “dumbing down.” The best writing makes complex topics easy to understand.
The clarity problem isn’t new; but organizations are now producing vast quantities of content for their audiences. And with that proliferation comes a quality control issue. In 2010, President Barack Obama signed the Plain Language Act to make U.S. government-created content less dense and confusing. Federal agencies must now use “plain language” to communicate more clearly with citizens.
There’s no equivalent plain-language law in the commercial sector, but, given how fiercely brands compete for audience attention, they should be addressing it voluntarily.
One financial organization my team worked with set an internal goal that all consumer-facing content must be of a grade eight to 10 readability level – an ambitious goal. Our organization also worked with government agencies that have similar objectives. For example, the Australian federal government aims for a grade five readability level as part of its digital service standard. All companies that create content for cus
