Abstract: ABSTRACTSearch engine optimisation grew a shadow discipline almost as soon as it appeared: link farms, keyword stuffing,cloaking and the other tactics that search engines spent two decades policing. Its successor, answer engine optimisation,is inheriting that shadow, but the target has changed. Where a manipulated search result competed for attention againstnine other links on a page, a manipulated answer arrives as a single synthesised statement, cited and confident, withnothing beside it for the reader to weigh it against. This paper treats adversarial AEO as a data-poisoning problem: themanipulation of the corpus an aggregation agent retrieves from, in order to control what it says. It sets out a taxonomyspanning commercial optimisation, the exploitation of sparse-data queries, indirect prompt injection and coordinateddisinformation, and reviews evidence that a handful of planted documents can steer a retrieval system with success ratesabove ninety per cent. It argues that aggregation agents are structurally more exposed than ranked search, because theyconcentrate authority into one answer and lend the trust of the aggregator to whatever source it cites. It proposes alayered defence, from provenance and source vetting at ingestion to corroboration at retrieval and inspectable citation atoutput, and connects these to earlier work in this series on auditability, confirmatory friction and misplaced trust. Itcloses with the defender's asymmetry and the unresolved question of who decides which sources are trustworthy.
