Frequently asked questions
What is a good keyword density?
There is no magic number. Write naturally; if a single keyword is well above 2–3% of your words it can read as stuffed. Use related terms instead.
What does the readability score mean?
It is the Flesch Reading Ease score. 60–70 is plain English that most adults read easily; below 30 is very difficult.
