Why it matters

Why this is worth checking

A forty-word sentence with three clauses reads fine to the person who wrote it and stops everybody else.

Grade level is a rough measure, but it catches what loses readers: sentences that never end and words chosen to sound expert.

What a finding means

Each finding says what was seen. This is what it tells you about the page.

A high grade levelMany readers will stop before the end of the sentence.

Very long sentencesThe longest ones are listed first, so you can start where they cost most.

JargonWords the reader may not share. Replace them with the word they would use.

FAQ

Questions

Is a low grade level always better?

For a landing page, usually. For a specialist audience, some jargon is expected, so judge it against who reads.

Can it tell if my copy is good?

No. It counts sentence length and syllables. Whether the copy is true and useful matters more.

Does the check change my site?

No. It only reads. Nothing is installed, edited or sent to your site by a check.
