How we get AI content to sound like the client and not generic AI
TL;DR: getting AI content to rank is easy, getting it to sound like you is the hard part. What worked for us was having the model extract style guidelines from our own writing, curating that list by hand, and feeding it only the guidelines instead of writing samples.
We've been making content with AI since ChatGPT came out, and honestly the ranking side of it is the easy part now. You match your headings to what AI is searching for, answer the question right after the heading, then back it up with a fact or a quote or a table. Machines eat that up.
The annoying part is content written that way comes out really dry and academic. Which is fine if you only care about ranking, machines like dry academic writing. But most of us also have humans reading the stuff and caring about the brand, so it matters.
First thing everybody tries is telling the model to add more warmth and personality, and it's just cringe. It'll give you a personality, it's just an unlikable one, and it still reads as AI. Telling it not to sound like AI doesn't do anything either, you can't really ask it to stop being itself.
What helped was calling out the specific tells. No "it's not x, it's y" framing, cut the empty adverbs (absolutely, actually), don't force every sentence to be a mic drop, no em dashes. That gets it to stop sounding like AI, but it still won't sound like you specifically.
Giving it your old articles as samples kind of backfires too, at least for us. It doesn't know what you liked about them so it grabs the wrong stuff and starts repeating the same phrases over and over.
The thing that worked better: in a separate chat, dump a bunch of your writing in and have it write out a long list of style guidelines it thinks it can pull from your writing. Then go through and keep only the ones you agree with. When you go to write real content, you just give it the curated guidelines, no samples, no example phrases.
Then it's just feedback over time. Every draft you mark up, and if you end up rewriting a chunk yourself, paste your version back and ask it what rule it should add. We've got clients past 100 guidelines at this point and the newer models handle a list that long no problem.
One thing I'd flag if you try this: make sure none of the voice guidelines end up breaking the SEO structure you started with. Easy to fix the tone and quietly wreck the part that was getting you ranked.
