‘What is readability?’ might not be your first question when drawing up content. But this means you could be missing out on a simple, easy way to ‘tune up’ your ROI.

How? Let’s take a closer look at some essential questions: What is readability? How does it improve the SEO of my website? What can I do to improve my own readability? What are the best tools to help me improve my readability?

Essentially, readability is about making your content as easy to understand as possible, for humans and algorithms alike. This is something that many brands underestimate. The truth is that people have different literacy levels.

You want everyone to be able to understand and enjoy your content. Beyond that, algorithms aren’t quite as smart as big tech companies would like to think they are. The importance of readability reflects this fact.

Today we’re going to cover everything you need to know about readability. Let’s start with the basics.

What is Readability in WordPress and Beyond?

What does readability actually mean? It’s simply the combination of sentence structure, the language you use, the length of your sentences and much more. It all adds up to the one question: is your content easy to read or hard to read?

Some of the factors that influence your readability include:

Sentence structure,

  • The language/tone used,
  • The length of your sentences,
  • Grammar used,
  • The length of the paragraphs,
  • Headings used and transition words used.

How Do I Get a High Readability Score?

The conventional wisdom is that your content should be useful for an expert, but that you’re granny should understand it. Of course, this ignores the fact that many people have smart grannies.

All the same, the basic principle is that anyone should be able to get the same value out of your content, regardless of their literacy or expertise.

So how can you achieve this?

As noted above, readability is made up of a handful of factors:

  • Sentence length: All sentences should be as concise and to the point as possible.
  • Vocabulary: Don’t use technical jargon where simple language will do.
  • Paragraphs: Generally, your paragraphs shouldn’t be any more than 3-4 lines long.
  • Style: Don’t use complex or overly literary styles.
  • Grammar: Avoid complex syntax like the passive voice and multi-clausal sentences.
  • Structure: Break your content up with subheadings, images and videos at least every 200-300 words.

You’ll read some people saying that you need to achieve a certain readability score for your content to be effective. The truth is a little murkier than this. Generally speaking, the higher your readability the better.

However, this needs to be balanced with providing good information. For example, in technical industries, it’s a lot harder to avoid complex vocabulary. As such, it’s important to have the most readable content possible, while still getting your point across.

Why is Readability Important?

There are many reasons why readability is important. First and foremost, users need to actually understand your content. Most people don’t finish Ulysses because they just find it too hard. The bookshop has already made their money though.

The same can’t be said about content marketing.

If someone finds your content too hard to read and gives up, they’ll leave your site. This tells the Google algorithm that they didn’t enjoy your site, so it won’t show it to other users. In this way, readability has a concrete impact on SEO.

The format of content also is important to the overall readability of your content. If your content doesn’t flow nicely it can become very difficult to read.

Similarly, if your images don’t flow with your content it can become difficult to read.

To help with images throughout your content, always make them consistent. Similar size images and images placed in similar areas of the page can also make your content easier to read.

The flow of your content can also allow you to get your message across much easier. Whether you are doing a review or writing a recipe, the flow of the content is vital.

At a basic level, your content should also be laid out in a visually appealing way. The thing to realise here is that people are lazy, especially on the internet. If you present users with large chunks of text, they’ll be less inclined to read it. User experience is key.

This is why short paragraphs are so critical.

How to Measure the Readability of Content
