Don't get me wrong, moaning is generally a sign you're doing it right, but not all women are vocal. With that said, other signs you're "stirring the skunk guts" correctly maybe; holding their breath, trying to crush your head like a walnut, not wanting to let you take a breath, making fists with their toes, handon the back of your head, tilting their pelvis (this is a trickier one, because they're arching just the lower back, if they were standing it would look like they are trying to push their ass out... if that makes sense, in any case they usually do it because you found the spot but they tend to tilt their pelvis in a way that makes it more and more difficult to stay on the spot... and they can get a bit irritated if you keep hitting the spot, but then keep stopping, your best bet is to put a pillow or two under their ass to keep it elevated when they start arching), if they start digging nails in it's usually a good thing.
But like someone already suggested, search it up, but don't watch the first one that it lists. The videos you want should be a chick explaining like everything. Everything, everything.
Like what parts are what, where you should expect to find things, what to do to isolate the clit with just your mouth, how to shape your tongue, and then what to do with it.
I would include a link, but the app doesn't seem to like the links I would suggest people watch.
Sorry.
But every women is different, and you should not be afraid to ask. If mouthing else just ask them to pat you on the head when you find a spot they like.
Too complex for that. Far more than a blow job. Buy this.

There's a tutorial on pornhub with Nina Heart, Ron Jeremy and two other guys who I forget the names of. Lol
Search how to eat pussy like a champ on pornhub probably better than anyone explaining.
