Frequently Asked Questions
What is a good readability score for an LPSG post?▼
A score of 75 or above indicates a well-readable LPSG post that is likely to receive good engagement. Scores between 50 and 75 are acceptable but have clear improvement opportunities. Scores below 50 indicate significant readability issues — usually single-paragraph walls of text, overly long sentences, or posts that are too short to convey meaningful content.
What is passive voice and why does it matter on LPSG?▼
Passive voice describes actions where the subject is acted upon rather than acting. For example: “The post was written by me” is passive. “I wrote the post” is active. Active voice is more direct, confident, and easier to read. Forum posts with high passive voice percentages feel weaker and less personal. Keeping passive voice under 10% of your sentences produces more engaging LPSG content.
How is the reading grade level calculated?▼
The reading grade level uses a Flesch-Kincaid style calculation based on average words per sentence and average syllables per word. A grade level of 6 to 9 is ideal for forum posts — accessible and easy to read without feeling overly simplified. Higher grade levels indicate complex vocabulary and long sentences that reduce readability on mobile forum interfaces.
How is this different from the LPSG Post Formatter?▼
The Post Formatter cleans your text — it fixes spacing, paragraph breaks, and line endings, then copies the cleaned result. This Readability Analyzer evaluates the quality of your writing — it scores word count, sentence length, passive voice percentage, and transition word use. They solve different problems and work best when used together: format first, then analyze.
