Answer Engine Optimization, or AEO, is the practice of engineering content so that answer engines — software that synthesizes a direct written response to a user question instead of returning ten blue links — quote, cite, or prominently feature your brand. AEO emerged as a distinct discipline around 2023 with the launch of ChatGPT Search, Perplexity, and Google AI Overviews. The technical levers differ from traditional SEO: instead of chasing backlinks and title tags, AEO rewards concise definitional sentences, FAQ schema, schema.org typed entities, and consistent NAP-style facts (name, address, phone, founding date) across the open web. Because answer engines build their outputs from a retrieval step over a fresh web corpus plus a generative step that paraphrases the retrieved passages, brands that appear in the retrieval set with consistent, quotable phrasing are dramatically more likely to be cited. Harch Atelier, the GEO/AEO practice inside Harch Corp, delivers AEO programs that audit existing answer-engine visibility, rewrite priority content into quotable answer blocks, and monitor citation share weekly using GLM-4-powered crawlers. AEO is the operational sibling of GEO: GEO is the umbrella concept, AEO is the executable practice.
