Why it matters
Readers recognise the worn phrases of generated text, and a website full of them looks as if nobody cared about the writing. For a post this counts double: the first sentence decides whether anyone reads to the end.
Search engines do not penalise text for being written with the help of AI; they penalise content with no value of its own. A generic text will not help even after a rewrite — humanisation gives it a better rhythm, not new information.
