Readability Checker Roundup: Top FREE Tools for SEO Content

Content Readability Definition

In this blog we will share some top tools if you are in need for a readability checker. But, what exactly is the readability definition?

It's the measure of how easily your target audience can read and understand your text.

Essentially, it's the difference between writing a scholarly article for experts and crafting a fun and engaging blog post for the masses.

And if you want your content to succeed, you need to nail down your readability game.

So, what's the best way to ensure your content is both readable and SEO-friendly?

We've compiled a list of the top FREE tools to help you out.

From tried-and-true readability checkers to powerful SEO content editors, we've got you covered.

What Makes Good Readability?

Good readability is the key to creating organic content that is easy to read, engaging, and memorable.

Firstly, it's all about the use of language.

Clear, concise language is key when it comes to readability.

Complex sentences, jargon, and technical terms can confuse readers and make your content difficult to follow.

Instead -> aim for shorter sentences and simple, everyday language that your audience can easily understand.

Another important factor is the structure of your content.

Long blocks of text can be intimidating to readers, while:

  • subheadings,
  • bullet points,
  • and numbered lists

…can help break up your content and make it more digestible.

Additionally, using visual aids such as images, graphs, and videos can make your content more interesting and help convey complex information in a simpler way.

Finally, it's important to consider your audience.

Different types of content require different levels of readability.

For example….a blog post aimed at the general public should have a much lower reading level than a technical report aimed at experts in a specific field.

Understanding WHO you are writing for and what they are looking for will help you tailor your content to meet their needs and preferences.

Frequently Ask Questions

How do I check content readability?

There are two main ways to check your content's readability:

  1. Online Readability Checkers: Many free online tools analyze your text and provide a readability score. These tools typically consider factors like sentence length, syllable count, and complex words.

  2. Readability Formulas: There are formulas like Flesch-Kincaid or Gunning Fog Index that you can use to calculate a score yourself. These require some math but offer more granular detail.

How do you calculate readability level?

There are different readability formulas, each with its own strengths. Most consider factors like:

  • Average Sentence Length: How many words are in your typical sentence? Shorter sentences are generally easier to read.

  • Syllable Count: How many syllables are in the average word? Fewer syllables make for easier reading.

  • Complex Words: How many words with three or more syllables are there? More complex words can slow readers down.

These formulas convert these factors into a score that corresponds to a U.S. grade level (e.g., 7th grade).

Is a 45 readability score good?

It depends on your target audience. A score of 45 might be appropriate for content aimed at high school students, but it could be challenging for a general audience.

Here's a general guideline:

  • 7th-8th grade level (score around 60): Good for a general audience.

  • 9th-10th grade level (score around 50): Suitable for a more informed audience.

  • Higher grade levels: May be appropriate for academic writing or targeting a specialized audience.

What is the automated readability index test?

This is a general term for any formula that calculates readability score automatically. Flesch-Kincaid and Gunning Fog Index are examples of automated readability indexes.

What is a good average length for a sentence?

There's no one-size-fits-all answer, but aiming for an average sentence length of around 15-20 words is a good starting point. Varying your sentence length keeps your writing engaging.

Is 70 a good readability score?

Yes, a readability score of 70 is considered good. It typically corresponds to a 7th-8th grade reading level, meaning the text is fairly easy to read. Texts with this score are suitable for a wide audience, including younger readers and those with average reading skills.
