What Google has said
Google's guidance focuses on the quality of content rather than how it was made. Using automation to generate many pages with little value for users violates its spam policies on scaled content abuse. Content that demonstrates experience, expertise and trustworthiness is favoured regardless of the tools used.
How to use AI for content safely
Start from what only you know: your process, prices, cases, customer questions and opinions. Use AI to structure, draft and edit, then have a person who knows the subject check every fact. Cite sources for claims. Publish fewer, better pages rather than many thin ones, and update them when things change.
