Entity and schema work makes your business readable to AI.

Entity and schema work makes your company one clearly identified thing online: the same name, service area, phone number and list of services everywhere your business appears, stated on your website in structured data that software can read without guessing. Both AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) rest on it.

What an entity is, in plain terms

Anything specific enough for a search engine or assistant to tell apart from other things is an entity, and your company is one. The difficulty is that software has to work out that separate mentions refer to the same company. Picture a La Mesa plumber with one name on its trucks, a longer legal name on a directory, and a call-tracking number from an old ad campaign on a third site. A person would connect them. Software may treat them as two or three businesses, or merge your details with someone else’s.

The facts that have to match

The business name, the address or service area, the phone number, the services offered and the website address carry most of the weight. Many home-service companies are service-area businesses with no public street address, so for them the list of cities served takes the place of an address and has to be the same list everywhere. I compare your website, your Google Business Profile and your directory listings line by line and write down every disagreement.

What structured data states

Structured data, often called schema, is a block of code on a page that states facts in a standard vocabulary. The page looks the same to a visitor. For a contractor, these types do most of the work:

Writing these blocks and validating them is the technical side of schema.

What schema doesn’t do

Markup won’t make an assistant recommend you, and a recommendation is something no one can guarantee. Nor can anyone outside these companies show that an assistant reads markup directly when it answers. It’s documented that search engines read structured data, and assistants that search the web lean on search engines, so I treat markup as a clear statement of facts, not a lever.

It also has to match what the page visibly says. I won’t mark up reviews you don’t display or services you don’t offer, because that breaks Google’s rules.

How I check whether it worked

The realistic result to watch is accuracy. Before any change, I use the AI visibility audit to record how assistants describe your company: which services, which cities, which phone number. After the facts are aligned and the markup is validated, I run the same prompts again about two weeks later. If an assistant stops saying you serve a city you left, or starts mentioning tankless water heaters once that service is stated consistently, I keep the change.
