Can I ask OpenAI or Google to correct information about my company?
There is no correction form and no support queue for this. The engines do not hold an editable record of you — they assemble a description at the moment of the question from whatever they trained on and whatever they just read. The only editable thing is the sources, which is why the work is almost entirely off your own site.
How long does it take for a correction to show up in AI answers?
Days for anything an engine re-reads on a live search, which is most of what you can influence. Weeks for a registry or database correction, because a person on their side processes it. Not at all for what the model recalls without searching — that changes when the model is retrained, which you do not control.
What if the wrong information is on a site we do not control?
That is the normal case and it is the part worth paying for. Most corrections are a form, an email and a wait, and they outrank anything you publish on your own domain because corroboration is what an engine weighs. There is no API for it, which is why most vendors skip it.
Does deleting the old page fix it?
Usually not, and sometimes it makes things worse. A deleted page can stay in a third-party copy, in the training data, and in whoever quoted it. The reliable move is to publish the correct version somewhere an engine already trusts, so the record disagrees with the stale version rather than falling silent.
