AEO Tool Stack by Budget: The $0, $100–300, and $500–1,200/Month Stacks
AEO tool investment scales from zero to enterprise - and the right stack for each budget delivers roughly proportional results if chosen carefully. This guide maps each budget tier to the best available AEO tools for each layer: question research, schema generation and validation, technical auditing, content optimization, and AI citation monitoring. Use this as a decision framework when building or upgrading your AEO tool stack.
