Most answer engines still start by retrieving pages from a search index. If your site isn't crawlable, indexed, and relevant, no amount of AEO will get it cited. So this work sits on top of ordinary SEO rather than replacing it.
What changes is how the content is written and how your reputation is built. A system summarizing an answer needs a clear, quotable statement and specific details it can't get anywhere else. It also leans on what other trusted sites say about you.
We stay away from tactics with little evidence behind them, like padding pages with FAQ blocks nobody reads or publishing hundreds of near-duplicate question pages. Our longer take is in Answer engine optimization, without the hype.
