Frequently asked questions
What is the Flesch score?
Flesch Reading Ease scores text from 0 (very difficult) to 100 (very easy) based on average sentence length and syllables per word. Higher means easier to read — most popular writing lands between 60 and 70.
What score should I aim for?
60–70 for general audiences — plain English most adults read comfortably. Marketing copy often targets 70+, while academic or technical writing can sit lower without being a problem.
Does readability affect SEO?
Indirectly, yes. Search engines reward content people actually read: clearer text lowers bounce rates and keeps visitors on the page longer, and both are signals Google pays attention to.
Will simplifying dumb down my content?
No. Clear writing respects the reader’s time — complex ideas land harder in simple sentences. Think Hemingway, not textbooks: short sentences can carry big ideas.
