Are readability tests and a readability checker the same thing?
You’ll hear them called by many different names including readability tests, readability scanner, readability index and similar terms. All of them refer to either the process itself or the resulting score that you get telling you how readable your content is.
What is a good readability score?
The readability number you get will depend on your target audience. If you’re writing a presentation for a group of nuclear engineers, you’d obviously want a higher readability score than if you were presenting to a group of college-bound high school students. Plus, different readability checkers look at different parts of your writing or web page to determine readability – some look at sentence length, others look at the words used. This can help you understand the “big picture” of the readability of your content.
What is the readability index?
A readability index is the measurement of how understandable your text is to your target audience. Different experts have taken different approaches to measure this, ranging from the number of complex syllables in a word to the number of words in a sentence. No one way is better than the other, but all of them are unique and give you a 360-degree view of how your writing is evaluated according to similar pieces of content in terms of readability.
Why should I check my work against so many readability formulas?
Getting the big picture of the readability of your content is vital not just to improve audience engagement, but also for your organic ranking in the search engines. When people can read, understand and act on your content, they’re more likely to recommend it, share it with others and consistently come back for more. Having a wide range of readability tests allow you to make sure that every piece you write is the best it can be.
