Content Readability Checker
Built by a certified Wix SEO expert consultant, this free tool analyses your content and returns a Flesch Reading Ease score, grade level, passive voice percentage, and actionable recommendations to improve clarity and SEO performance.
For accurate results, paste at least 100 words. Plain text works best — HTML tags are automatically stripped from the analysis.
Tip from your Wix SEO consultant: Aim for a Flesch score above 60 for most web audiences. A grade level of 7-10 is ideal for blog posts and landing pages.
Readability Best Practices for SEO Content
Target a Flesch score of 60-80
For most websites, a Flesch Reading Ease score between 60 and 80 strikes the right balance between clarity and depth. Scores in this range are readable by the widest audience and tend to perform better in search.
Keep sentences under 20 words on average
Long sentences are harder to parse for both readers and search engines. Break complex thoughts into two shorter sentences. This single change can significantly improve your readability score.
Use active voice over passive voice
Active voice ("We built this tool") is more direct and engaging than passive voice ("This tool was built"). Keep passive voice below 20% of your sentences to maintain reader engagement.
Replace jargon with plain English
Complex, multi-syllable words increase cognitive load. Where possible, use everyday alternatives. "Use" instead of "utilise", "help" instead of "facilitate". Simpler language converts better too.
Structure content with short paragraphs
Online readers scan before they read. Use short paragraphs of 2-4 sentences. White space makes content feel approachable and reduces bounce rate — a positive signal for SEO.
Match grade level to your audience
A B2B SaaS blog may justify a higher grade level than a retail product page. Know your audience and calibrate accordingly. A Wix SEO consultant can tailor content guidelines to your specific niche and goals.
