THE WHOLE COMPARISON

One sheet. No toggles. Read it and decide.

Compare the purpose, work and evidence. The boundaries overlap, so a proposal should name deliverables instead of charging for an acronym alone.

02
WHY ONE BUILD

Shared foundations, different observations.

A useful, accessible page can serve several search surfaces. That overlap does not guarantee three returns or remove the need to test each surface.
The pages
WHAT A BUYER CAN READ AND VERIFY
  • Map distinct intent to one strong page
  • Answer questions about the same buyer task together
  • Show evidence and a clear next step
  • Create location pages only where useful local distinctions exist
Make the page accessible and worth using. Then observe whether a search engine indexes it or an answer cites it; do not assume a published page enters every model’s training data.
The proof
FACTS THAT CAN BE CHECKED
  • Schema and entities so a machine knows what it is reading
  • Reviews, directories, and press that say the same thing
  • A named human with real credentials behind the work
Accurate claims and relevant sources make the page more useful to people and systems. They do not establish a known threshold at which an engine will recommend the business.
03
WHICH ONE YOU NEED

The honest version of that question.

Start with the business problem. Repair blocked access first, address high-value unanswered needs next, and test a bounded AI visibility question set when it supports the buying journey.

  • Customers find you by searching for the thing you do
  • Your competitors are easy to find in Google and absent from AI answers
  • One channel breaking open would change your year
  • You can approve a build and let it run

  • Nobody has ever searched for what you sell, and you need demand creation instead
  • You have a site nobody can edit and no budget to change that
  • You need a lead this month to make payroll
  • You are still deciding what business you are in

STRAIGHT ANSWERS

The questions this page exists to answer.

What is the difference between SEO, AEO and GEO?

SEO concerns organic search visibility. AEO emphasizes direct answer surfaces. GEO emphasizes generative answers. AEO and GEO overlap, and there is no universal boundary between them.

Does AEO only apply to voice search?

No. Direct answers can be typed, spoken or shown within search results. Input method does not create a clean boundary between AEO and GEO.

Do I need three separate retainers?

Not automatically. Many tasks overlap, while separate research, technical work or measurement can require additional effort. Ask for deliverables, owners and costs so shared work is counted once.

Which work should come first?

Start with the business objective and evidence. Fix access problems, improve important pages that fail the buyer’s task, and decide whether a repeatable AI answer sample will help the business make a decision.

Use the AI search visibility review to connect these definitions to a scoped set of checks and a consistent measurement method.

Do the three have different fixed timelines?

There is no reliable product-wide deadline. Search access, crawling, retrieval, competition and feature settings all matter. We agree implementation milestones and review dates, then repeat the same bounded question set. We do not promise a citation or a model retraining date.

How should success be measured?

Record the engine, mode, question set, geography, date and sampling method. Track business mentions and cited URLs separately, then review search data and qualified demand where available. Google’s current Search documentation describes a Generative AI performance report; use the reports available to the property and keep their scope distinct from our sampled answers.
