The five signals

The five, in Bay Area AEO's words

The signals come from the interactive demo on Bay Area AEO's site, where a visitor picks a customer question, chooses an AI platform and switches the signals on one at a time to watch a simulated business move from “not mentioned” toward the answer. The agency labels the demo a simulated example; real answers vary by platform and change over time. The five signals it uses are the right list for a handbook all the same, because each one maps to a step in how an assistant builds an answer.

Signal 1: consistent listings

An assistant answering a local question reads listings before almost anything else, because listings hold the facts that filter the answer: where the business is, when it is open, what category it belongs to. Bay Area AEO's definition is narrow on purpose: the name, hours and address match on Google, Bing, Apple Maps and Yelp. Those four platforms feed most of the assistants in common use, directly or through partners.

Consistency matters more than completeness at first. A listing with the right hours on Google and old hours on Yelp is worse than a plainer listing that agrees everywhere, because the conflict gives the assistant a reason to doubt both. The fix is unglamorous: one master record, then every platform brought into line with it.

Signal 2: specific reviews

Reviews do two jobs in an AI answer. Their volume and rating help a business make the shortlist, and their wording supplies the reason the assistant gives. Bay Area AEO's definition puts the weight on the second job: customers describe what the business does best, in their own words.

A review that says “Dr. Lee was incredibly patient with my son, who is terrified of the dentist” answers the anxious-patient question directly. Ten reviews that say “great service” do not. The work here is asking at the right moment and making it easy for a customer to mention the specific service, never writing reviews or offering rewards for them.

Signal 3: an answer-ready website

The business's own site is the one source it controls completely. An answer-ready site has clear pages that answer the exact questions people ask AI. In practice that means one page per important service, written in plain language, with the conditions stated in text: prices or price ranges, service areas, hours, insurance, lead times, policies.

Bay Area AEO's FAQ makes a point that saves owners money: a new website is usually not needed. The agency works with a business's existing site and adds what AI needs, meaning clear service pages, FAQs, structured data and accurate business details.

Signal 4: structured data

Structured data is code on a web page, usually in a format called JSON-LD, that states facts in a form machines read without guessing. Bay Area AEO's definition: schema markup tells AI the services, service area and hours. It does not replace readable text; it confirms it. When the markup and the page say the same thing, a crawler has two matching statements of the same fact.

Signal 5: trusted mentions

Assistants give weight to what other people say about a business. Bay Area AEO's definition, word for word: local press, guides and directories mention the business by name. A neighborhood guide naming a bakery's croissants, a trade association's member directory listing a contractor, a local news story quoting a financial planner: each is an independent statement an assistant can cite, and each makes it more comfortable naming the business.

This is the slowest signal to build and the hardest to fake, which is why it carries weight.

The signals change shape by industry

The five are general. Bay Area AEO's forty niche pages show how each one takes a specific form in a specific trade. For dentists the list starts with insurance and payment clarity and provider credentials that match Healthgrades and Zocdoc as well as state license records. For plumbers it starts with 24/7 and same-day clarity and CSLB C-36 license verification. For restaurants it starts with menu markup and text menus. For wineries it starts with tasting experience details and itinerary facts. Part 6 of this handbook walks through every industry.

The niche signals are mostly the general five with the trade's own conditions filled in. A CSLB license number is a credential; it belongs on the website, in the structured data and on the listings, all matching. An insurance list is a condition; it belongs on the site and the profiles. Thinking of them that way keeps the work organized.

The order to work in

The signals are not equally fast. A sensible order, and the one this handbook follows, is:

How the signals reinforce one another

The five signals are listed separately, but an assistant reads them together, and each one makes the others more believable. Take a physical therapy clinic in Pleasanton that wants to be named for ACL rehab. Its Google profile lists sports rehabilitation among its services. Its website has a page on ACL recovery that names the therapist who leads it and her sports certification. The structured data on that page marks it up as a medical service offered at the clinic's address. Reviews from patients mention getting back to soccer after surgery. A local high school's athletic department lists the clinic as a partner.

No single item there would carry the answer. Together they give the assistant five agreeing statements from five kinds of source, and the reason it writes (“known for ACL rehab with athletes”) can be traced to all of them. Bay Area AEO's physical therapy page lists the same ingredients in its own terms: specialty programs, therapist profiles, referral partner mentions and specific reviews.

What a weak and a strong signal look like

A useful habit is to describe each signal at two levels, so the work has a clear target.

Checking the five yourself

An owner can grade a business against the five signals in an afternoon. Search the business name on Google Maps, Bing Maps, Apple Maps and Yelp, and compare the name and address, then the phone number and hours. Read the last twenty reviews and count how many mention a specific service. Open the website on a phone and look for a page that answers the most common customer question, with the condition in text. Paste the home page address into a structured-data testing tool and see whether LocalBusiness markup exists. Search the business name in quotes and count independent mentions in local press and guides or on association sites.

Write a one-line verdict for each signal. That page is the plan for the next three months.
