The tell is simple. Ask an assistant the question your best customer would ask on the way to buying, in the words they would use, and see whether your name appears in the sentence. Not in the links underneath. In the sentence.
Do it three or four times, because the answer moves between runs. If your name never lands, you are not being penalised for anything. You are simply not in the sources the engine reached for, which is a different problem with a different fix.
The thing that catches people out is that traffic looks fine while this happens. A citation with no click leaves no trace in analytics, and a mention with no link leaves none at all, so the channel can be moving buyers away from you without a single number on your dashboard changing.
