Readability Checker Readability Guide

Why readability matters for SEO

Google wants to serve content that users find useful. When users land on a page and immediately leave because the writing is hard to follow, that is a negative signal. Time on page, scroll depth and return visits are all influenced by how readable your content is.

The AI connection: AI systems like ChatGPT and Perplexity prefer to cite content that is clear and direct. Dense, complex writing is harder to extract clean answers from. Readable content gets cited more frequently.

The most impactful readability improvements

Shorter sentences

The single most effective readability improvement. Aim for an average sentence length of 15-20 words. Sentences over 30 words should almost always be split. Look for conjunctions — and, but, because, which, that — as natural split points.

Simpler words

Replace complex words with simpler equivalents. Use "use" not "utilise". Use "help" not "facilitate". Use "start" not "commence". Each unnecessary syllable makes your text marginally harder to read — across a 2,000 word article, they add up.

Shorter paragraphs

On screens, dense blocks of text are harder to read than paragraphs of 2-3 sentences. White space is not wasted space — it gives the reader's eye time to process information and makes the page feel less intimidating.

Subheadings every 200-300 words

Subheadings help readers scan for the section they need and break up long content into digestible chunks. Every subheading is also a potential match for a search query or AI question.
