What is Readability?

Readability in the simplest of terms is how easy-to-read your article is. In other words, it is the quality of your writing.

If your text has a high readability value, it means that your readers will be able to understand your sentences easily. And if it’s low, they may still be able to understand what you’re saying but in a more stressful way.

This is why it’s advisable to go for high readability scores when writing. Because it reduces misunderstandings and allows your reader to easily comprehend the information you’re trying to pass through.

More so, as a writer, you should be more concerned about how readable your content is, as it shows how engaged your readers are with it.

One way to have this under control is to reduce the number of complex words that you use. I’m not saying they’re bad, but using too many of them requires lots of attention from your reader. Honestly, nobody has the patience to give.

Why Is Readability Important?

This question is similar to asking “Why is oxygen important?” The answer to that is endless. Oxygen is life to every living thing on earth, so is readability.
