How does readability affect SEO?
Readability doesn’t directly influence SEO. That being said, Google does use multiple ranking factors related to user experience like: Click trough rate (CTR), Bounce rate, Time on page and Returning visitors. If your text is just too hard to understand, you can expect users to leave your page before reading the full content. Hard to read content has a much bigger chance to result in: Higher bounce rates, Lower CTRs and Visitors not engaging with your content (sharing it on social, leaving a comment or linking back to your content). All these factors are very likely to have a negative impact on SEO.
How to Increase your readability Score?
- Use simple words.
- Write short sentences.
- Use headings and subheadings.
Readability formulas give you and great indication on how accessible your content is, but you shouldn’t just focus on your calculated score. It’s way more important to connect and write with your audience in mind (these are real people ;-). And depending on your audience and the topics you write about, you should choose the right index and range to use as an indication when testing a document.
