What is readability? Why it matters and how to improve it.

In the ever-expanding digital landscape, where attention spans are fleeting and competition for reader engagement is fierce, the concept of readability emerges as a beacon of guidance for copywriters and bloggers alike.

Think of readability as a bridge between your ideas and your audience. It’s the difference between a maze and a scenic route – one frustrates, while the other beckons exploration. When your content is readable, your message resonates. When your words flow smoothly, your ideas are understood. When you master readability, you become an enchanting storyteller.

Elevate your blog’s readability, and watch as your content transforms into an immersive haven that keeps readers coming back for more.

What is Readability?

Readability refers to how easily a reader can understand a written text.

While readability itself does not directly influence your ranking on Google, it plays a crucial role in user engagement. Google takes user engagement into account for ranking decisions.

Put simply, content that’s difficult to read receives less user interaction, fewer backlinks, and as a result, doesn’t perform well on Google or other search engines.

Improving your content’s readability will result in more visitors who read your content, share it on social media and link back to it from other websites. This, will in turn, boost your ranking position.

So, whether you’re a copywriter or a blogger, mastering the art of improving readability is crucial.

Why Readability Matters

Content readability is crucial for a blog because it directly impacts user experience, engagement, and overall success. When your content is easy to read and understand, it:

  1. Engages Readers: Readable content keeps readers interested, encouraging them to stay on your blog longer and explore more articles. This, in turn, reduces bounce rates that can negatively affect your ranking potential.
  2. Improves Comprehension: Clear writing helps readers grasp your message and ideas without confusion, leading to better retention of information.
  3. Boosts Sharing: Readers are more likely to share content they find easy to understand, extending your blog’s reach through social media and word-of-mouth.
  4. Enhances SEO: Search engines value user experience, and readable content improves user engagement metrics, indirectly contributing to higher search rankings.

As you can see, improving readability on your site will give many positive benefits to your site.

Factors Influencing Readability

Let’s explain briefly the factors that affect readability.

Sentence structure and length

keep it simple

Opt for concise sentences that are easy to read and comprehend. Aim to limit paragraphs to just 2-3 sentences each, allowing your readers to effortlessly navigate your content.

Not only does this approach enhance readability, but it also encourages you to present your ideas more succinctly. Embrace simplicity in your writing, striving to convey your message in the most straightforward and accessible manner.

Make your content a pleasure to read by presenting your ideas in a simple way.

Content Language

Use simple, easy to understand, language. Break down difficult concepts into simpler terms. Choose strong active verbs over passive verbs.

Let’s me briefly explain active voice and passive voice and why you should try to use active voice when writing.

Active voice and passive voice are two different ways of constructing sentences. In active voice, the subject performs the action, while in passive voice, the action is received by the subject.

Active voice: The chef prepared the meal.
Passive voice: The meal was prepared by the chef.

Active voice sentences are more engaging and personable, while passive voice sentences can make writing feel dull and monotonous. Active voice also helps to place focus on the subject, making writing more direct, clear, and easy to read.

Prefer active voice because it is simpler, more direct, and easier to read and understand.

Avoid high syllable words

Avoid using long and complicated words. Remember, not all readers have advanced literacy skills, and some might be reading your content in a second language.

High syllable words are difficult to understand and can confuse some of your audience. Your objective is to effectively convey information to your audience, so opt for words that are simple and easily understood.

Furthermore, using complex words can discourage regular readers from quickly skimming your content. Readers often skim through content before deciding whether to read more deeply. By using simpler words, you help in this process, making sure your content is accessible and interesting to a wider audience.


Use a simple font that is easy to read. Ensure font size is large enough that most of your audience can read it. Ensure there is enough vertical space between sentences (this is line-height).

Colors and contrast on your website

A significant number of your audience likely suffer mild or severe color blindness. Colored text or backgrounds could be difficult, or impossible, to read.

Use high contrast colors throughout your website and for all your content

White Space

White space is the space (normally white) that is between your text, headings, links, etc. It’s important to have plenty of white space to separate your blocks of text, otherwise, reading the content can become tiresome.

In your website design, make sure to incorporate space around your paragraphs, headings, subheadings, lists, and images. Your theme will provide options for specifying appropriate spacing on your website.

For WordPress users, I recommend the GenerateBlocks, which offers six additional blocks that can be used in your content, providing extra customization for spacing, as illustrated below:

Be Familiar

Use words, phrases, and jargon that your target audience is already familiar with. For instance, this website can use terms like SEO without needing to explain every time what it stands for (Search Engine Optimization – in case you’re unsure).

If you introduce a term or acronym your audience isn’t familiar with, it’s important to provide an explanation – otherwise, you’ll leave your audience confused.

Spelling and grammar

Spelling and grammar mistakes stand out to your readers. They represent a lack of attention to detail and will undermine trust and credibility in your content.

Moreover, they can negatively impact your ranking position, as Google can detect these errors in your content.

Spelling and grammar mistakes are a sign of low-quality content. Too many pages detected by Google of this type could cause a site-wide penalty to apply to you. This affects all your content, even content without spelling or grammar mistakes.

Always proofread your content before publishing.

Use visuals

Break up your text by including engaging visuals such as images, charts, infographics, or other visual content. This practice provides your readers with a well-deserved breather from the textual content.

Moreover, visuals have a remarkable ability to clarify and illustrate the points you’re conveying in your text. They say a picture is worth a thousand words, and that holds true! Images are processed much more swiftly than text, instantly grabbing your audience’s attention and enhancing their understanding.

Strategies to Improve Readability

Let’s go over some actionable tips you can take to enhance readability on your website or blog.

Break down complex concepts

Some topics can be dense or difficult to understand, especially for non-experts. Try to explain these topics in ways a non-expert can understand.

Use ChatGPT or another AI tool to help you explain difficult concepts in simple terms. For example, here I ask ChatGPT to explain how rocket engines work:

how do rocket engines work

The “eli5” at the end stands for “explain it like I’m 5”. Of course you can ask for an explanation at any level, not just 5.

Use good formatting techniques

To make content highly readable and easy to read, there are several formatting rules that can be followed. Here are some tips:

  • Use headings and subheadings to break up the text and make it easier to scan
  • Use lists to organize information and make it more digestible
  • Use clean typography and avoid using all caps or underlining text
  • Use left-aligned text and provide the right amount of space between lines of text
  • Use bolded text to highlight key words in a sentence and to aid skimming of your content
  • Try to write short sentences and use whitespace to guide readers through the post
  • Choose a font family, style, weight, size, color, and line-height that are legible and readable on screen

Select fonts that are legible and easy on the eyes. Avoid using decorative or overly stylized fonts. Opt for clean and well-designed fonts.

Use font color and contrast to improve accessibility

color blindness

Not everyone has perfect vision or eyesight. Color blindness is a common condition, 8% of males in Northern Europe suffer from red-green color blindness and 0.5% of females. A small number of individuals suffer from total color blindness.

It is recommended to use high contrast colors on your website to maximize the number of people that can easily read your content.

Tools and Resources

Now that you’re well-versed in the importance of readability, let’s explore the tools and resources that can help you.

SEO plugins include reading score calculators that provide a readability assessment as you write your content. If you’re a WordPress user, popular SEO plugins like Yoast SEO and RankMath integrate such features seamlessly.

In my own experience, I opt for the All in One SEO plugin, which not only includes a readability score but also evaluates various aspects including:

  • Images/videos in content
  • Paragraph lengths
  • Sentence lengths
  • Passive voice (avoid, use active voice instead)
  • Transition words
  • Consecutive sentences
  • Subheading distribution
  • Flesch reading ease

This comprehensive assessment of readability boosts your content quality as you write it.

The free version of the All in One SEO plugin includes a readability score. Therefore, there’s no immediate need to invest in the premium plan unless you’re seeking additional premium features.

Proofreading and grammar tools


Various proofreading tools are available to improve your content by spotting those sneaky spelling and grammar errors.

I personally prefer to use ChatGPT to proofread my content. For instance, you can provide ChatGPT with a text passage and request it to identify and correct spelling and grammar errors. Learn more about prompting ChatGPT in this article: ChatGPT prompts for Copywriters.

If prompting an AI is not for you, no problem! Well-known grammar checkers are available, I suggest:

Grammarly – Sophisticated grammar and spelling checker

Hemingway website – A hassle-free, free-of-charge proofreader
