TL;DR:
TinyIMG checks the readability of your product titles and descriptions using 7 standard formulas like Flesch and Gunning Fog. We clean the text, run the analysis, and show which scores pass. If at least 3 out of 7 pass, your content is marked as readable - helping improve SEO, AI understanding, and user experience.
How we check readability
We automatically evaluate the readability of your product titles and descriptions to ensure they’re clear, accessible, and optimized for both your customers and AI models. We use a set of industry-standard readability formulas to measure how easy your content is to read.
Why it matters
Readable content:
Boosts customer trust and conversions
Improves SEO performance
Helps AI models better understand your content
Makes your store more accessible to a wider audience
How we do it
We use the TextStatistics library by Dave Child to analyze your content. Before analyzing, we:
Decode HTML entities
Remove non-breaking spaces and HTML tags
Clean the text to ensure accurate scoring
We then run your content through seven well-known readability formulas:
Readability scores we check
1. Flesch reading ease
Measures how easy the text is to read
Higher = better
Passes if score is ≥ 45
2. Flesch-Kincaid grade level
Converts readability into a U.S. school grade level
Lower = easier
Passes if score is ≤ 10
3. Gunning fog score
Estimates the years of education needed to understand the text
Includes sentence length and complex words
Passes if score is ≤ 12
4. SMOG index
Focuses on polysyllabic (3+ syllables) words
Designed for healthcare and educational materials
Passes if score is ≤ 11
5. Coleman-Liau index
Based on average characters per word and words per sentence
Uses character count instead of syllables
Passes if score is ≤ 12
6. Automated readability index
Similar to Coleman-Liau but designed for typewritten content
Considers characters per word and words per sentence
Passes if score is ≤ 10
7. Dale-Chall score
Compares your words against a list of 3,000 commonly known words
Penalizes unfamiliar or complex words
Passes if score is ≤ 7.5
How we determine readability status
Each formula returns a score. If at least 3 out of the 7 formulas pass their respective thresholds, we mark the content as "readable".
This makes it easy to spot problems and improve your content for real people and search systems.
