Why it matters
There is no minimum word count in Google's rules, but a page with only a sentence or two gives search engines and AI answers little to understand, quote or rank. Pages that rank for competitive searches usually explain the subject in a few hundred words at least.
How to fix it
Say more about what the page offers: who it is for, what is included, answers to the questions buyers ask. Aim for 250 words or more of text that a reader would actually want.
