What is answer engine optimization for a local trade business?

It is the work of making your own pages and your Google Business Profile the source that Google, Bing and assistants use when a customer asks a question about your trade, such as whether a dentist is open on Saturday or how long a roof replacement takes. For a trade, it adds one condition to general AEO: every answer must also follow that trade's advertising rules.

Which trades does the AEO by industry guide cover?

Six: dentists, lawyers, home service trades (plumbers, electricians, heating and cooling companies and roofers, in one guide), restaurants, real estate agents, and accountants and tax preparers. Each guide covers the questions customers ask, the answer places that matter, what the pages and the Business Profile must state, the structured data type, and the advertising rules for that trade, with sources.

Why are the rules stricter for dentists, lawyers and accountants?

For two reasons. Each of these professions has codes or rules that speak to advertising in detail, from the dental association's code to the state bar rules and the AICPA code. And Google's helpful content guide says its systems rely more on signs of trust for topics that can affect a person's health, financial stability or safety, which it calls Your Money or Your Life topics.

Can Licheo tell me whether my advertising wording is legal?

No. Licheo builds and improves websites for search and AI answers, and the guides in this series restate what the rule texts say, with links to each source. Whether a sentence is allowed for you depends on your state, your license and your membership, so ask the body that licenses you, or your own lawyer, before you publish a claim you are unsure of.

Do all six trades use the same structured data?

They use the same Google feature, Local business, but each uses its own Schema.org type: Dentist, LegalService, Plumber or another home service type, Restaurant, RealEstateAgent or AccountingService. Google asks for the most specific sub-type possible, and a business with several trades lists several types. Restaurants add properties of their own, such as the menu address and the cuisine.

Does a trade business need Local Services Ads to become the answer?

No. Local Services Ads is Google's advertising program for local service businesses, and the answer places in this guide (the Business Profile, the featured snippet, People Also Ask and AI answers) come from your profile and your pages. The program's screening lists are still useful, because they show which facts Google treats as proof, such as licenses, insurance and background checks.

Which advertising rules apply if my business works in two states?

Rules are set state by state, so check each state where you advertise or work. Florida's rules for lawyers, for example, apply to lawyers who advertise legal services in Florida or target Florida residents, and Google's Local Services pages note that a business on the border of two states may not be authorized to work in both. Check with the licensing body in each state.

How long does Google's screening for Local Services Ads take?

Google's United States requirements page says that, on average, the process takes 3 to 4 weeks to complete after the documents are submitted, and recommends starting as soon as possible after creating the account. Some checks apply only to select users or categories, and Google may ask a business to repeat checks later to keep its badge and its ads running.

How much does Licheo charge for AEO for my trade?

The figure depends on the trade, the number of services and the state of your site and profile, so contact us for pricing. A good first step is the free Get Found Check, which reads your homepage and gives a letter grade, three to five quick fixes and a separate grade for readiness for AI assistants in under 60 seconds.

AEO by industry: how dentists, lawyers, home service trades, restaurants, real estate agents and accountants become the answer

One guide for each of six trades: the questions their customers ask before they call, the answer places that matter for each, what the pages and the Business Profile must state, and the advertising rules that limit what each trade may write.

See if customers can find you

Every trade becomes the answer in the same basic way (a verified Business Profile, one page per service with the answer in its first lines, and facts that match everywhere), but six things change from one trade to the next: the questions customers ask before they call, the answer places that matter, the Business Profile rules, the structured data type, the checks Google runs before the business may advertise, and the advertising rules of the profession. That last difference decides what each page may claim: dentists answer to the American Dental Association's code (for its members) and the Federal Trade Commission's guides, lawyers to the rules of each state, real estate agents to federal fair housing rules and, for members, the REALTOR code, accountants to the AICPA code and the IRS, contractors to state license boards, and restaurants mainly to Google's own menu and hours rules.

What changes in answer engine optimization from one trade to another?

Answer engine optimization, or AEO, means making your own pages and your profile the source that Google, Bing and voice assistants use as the direct answer to a question. The places where those answers appear have names: the featured snippet (the boxed result in which Google shows the answer text first), People Also Ask (the list of related questions that open to a short answer from a web page), the knowledge panel and the Business Profile in Google Maps and Search, and the answers at the top of Google's AI features and in assistants.

Three earlier guides in this series explain those places for any business. The main guide to answer engine optimization describes each answer place and what Google says about it. The guide to local answer engine optimization covers the Business Profile, reviews, near me searches and hours on maps. The guide to AEO page by page takes the homepage, service pages, FAQ page, blog posts, product pages and About page one at a time. This guide links to them and adds the one thing they leave open: the trade.

Why does the trade matter? Because a dentist, a plumber and a lawyer receive different questions, meet different rules on Google, and above all work under different advertising rules. Take the phrase "the best in town". Florida's rules preclude a lawyer from claiming to be the best, or one of the best, in a field of law unless the claim can be factually substantiated, while none of the rules quoted in this series forbids a restaurant to say it. Let's say it plainly: in the regulated trades, the answer has to be true, complete and allowed, all three at once.

How do the six trades compare?

The table sets the six trades side by side. The first two columns are our own illustration, written to show the typical starting point for each trade; the last two columns come from the sources named on this page and in each trade's guide.

Two patterns stand out. The trades where a mistake can hurt a person's health, money or legal position (dentists, lawyers, accountants) carry professional codes that speak to advertising in detail, and two of them, the dental code and Florida's bar rules, name websites directly. The trades where the need is often urgent (plumbing, electrical, heating and cooling) meet extra checks in Google's own screening, which calls them urgent categories.

The six trades compared. Example question and main answer place: written by Licheo on 17 October 2026 as an illustration, with no search counts. Schema.org type: schema.org, read 17 October 2026. Rule makers: as named in the sources on this page.
Trade	Example question before the call	Answer place that matters most	Schema.org type	Who writes the advertising rules quoted in its guide
Dentists	emergency dentist open Saturday	Business Profile hours and booking link; treatment pages	Dentist	American Dental Association code (for members); Federal Trade Commission guides
Lawyers	how long does probate take	Practice area pages; a profile for each lawyer	LegalService	Each state's rules; this series quotes California and Florida
Plumbers, electricians, heating and cooling, roofers	water heater leaking at night	Map, hours and call button; one page per job	Plumber, Electrician, HVACBusiness, RoofingContractor	State license boards; this series quotes California's
Restaurants	can I book a table for 6 tonight	Business Profile menu, hours and buttons	Restaurant	Google's menu and hours rules; the Food and Drug Administration for chains of 20 or more
Real estate agents	how long do houses take to sell here	Neighborhood and guide pages; the agent's profile	RealEstateAgent	Department of Housing and Urban Development; REALTOR code (for members); state license rules
Accountants and tax preparers	can an accountant talk to the IRS for me	Team and fees pages; service pages	AccountingService	AICPA code (for members); Treasury Circular 230; state boards of accountancy

Why does Google ask more of dentists, lawyers and accountants?

Google's guide to creating helpful, reliable, people-first content, updated on 5 October 2026, explains it plainly. Its systems give even more weight to content that aligns with strong E-E-A-T for topics that could have a large effect on the health, financial stability, or safety of people, or on the welfare or well-being of society, and Google calls these "Your Money or Your Life" topics, or YMYL for short. E-E-A-T is Google's short name for experience, expertise, authoritativeness and trustworthiness, and the same guide says that of these aspects, trust is most important.

A dental page about implants, a legal page about probate and a tax page about an IRS letter all sit in that group. In practice, this means the page should show who wrote it and which license or credential that person holds, should name the official source behind each rule or figure, and should date what changes. These are also the facts the professional codes ask for, so the work serves Google and the rules at the same time. Plumbing, electrical and restaurant pages can touch safety too, for example a page about gas lines or about allergens, and those pages deserve the same care.

Which Google Business Profile rules depend on the trade?

Most of Google's Business Profile guidelines apply to every business, but a few change with the trade. The guidelines define an individual practitioner as a public-facing professional, typically with their own customer base, and name doctors, dentists, lawyers, financial planners, and insurance or real estate agents. Those practitioners may have profiles of their own, with a title or degree such as Dr., JD or Esq. in the name, while support staff should not create their own Business Profiles.

Restaurants have their own hours rule: Google asks for the hours when diners can sit down and dine, and only then takeout, drive-through or delivery hours. Real estate agents meet a limit on what may have a profile, since Google's getting started page says profiles aren't for online-only businesses nor properties for rent or sale. Service-area trades such as plumbers and roofers follow the service area rules that our guide to near me searches explains. Each trade guide in this series sets out the profile rules for that trade in full.

What does Google check before each trade may advertise?

Google runs an advertising program for local service businesses called Local Services Ads, and its help pages show, trade by trade, what Google treats as proof that a business is real. Google's screening page says that all businesses must pass Google's screening and verification process, which varies by business category and location and may include background, business registration, insurance, and license checks, and minimum review requirements. The licenses Google verifies are displayed on the provider's profile, checked against the state or country databases.

The United States requirements page then changes from trade to trade. Dentists need state practice and provider licenses and, for health care, verification of their National Provider Identifier. Lawyers need a state bar license check for each lawyer. Plumbers, electricians and HVAC companies are urgent categories with background checks for the people sent into homes. Real estate agents need license checks for each agent, and tax specialists business license checks. Restaurants need only a verified Business Profile, and the Google Verified badge is currently unavailable for dining. On average, Google says, the process takes 3 to 4 weeks after the documents are submitted.

The answer places this guide describes come from the profile and the pages, with or without these ads. The list is still useful, because it tells each trade which facts to show on its own pages so that customers and assistants can check them.

Which structured data type fits each trade?

Structured data is a set of labels in the page code that tells a search engine what each part of the page is, such as the business name, the hours or the menu. Google's local business guide, updated on 8 September 2026, asks for the most specific LocalBusiness sub-type possible, and allows several types as a list when a business does several things, giving its own example of a business typed as Electrician, Plumber and Locksmith together.

Schema.org, the shared vocabulary for these labels, has a specific type for every trade in this series: Dentist, LegalService, Plumber, Electrician, HVACBusiness, RoofingContractor, Restaurant, RealEstateAgent and AccountingService. Google's list of supported features, updated on 16 October 2026, holds 25 features and none of them is made for a single trade; all six trades use the Local business feature, which Google describes as business details displayed in the Google knowledge panel, including open hours, ratings, directions, and actions to book appointments or order items. The trade guides give the details that matter for each type, such as the menu property for restaurants and the Attorney type that Schema.org has retired in favor of LegalService.

Who writes the advertising rules for each trade?

This is the part of answer engine optimization that differs most between trades. The list below names the rule makers whose texts this series quotes, with the scope each text gives itself. We restate what each rule text says, for information only, and the rules for your state or your membership may differ. Before you publish a claim you are unsure of, check with the body that licenses you.

Dentists: the American Dental Association's Principles of Ethics and Code of Professional Conduct, binding on members, with an opinion on websites and search engine optimization (5.F.6); the Federal Trade Commission's endorsement guides for testimonials.
Lawyers: the rules of each state; this series quotes California's Rules of Professional Conduct, chapter 7, and the Rules Regulating The Florida Bar, chapter 4, which treats websites the same as other advertising media.
Plumbers, electricians, heating and cooling companies and roofers: state license boards; this series quotes the California Contractors State License Board, which reminds contractors that the license number belongs on websites.
Restaurants: Google's own menu and hours guidelines, and the Food and Drug Administration's menu labeling rules for chains of 20 or more locations.
Real estate agents: the federal fair housing rule at 24 CFR 100.75, Article 12 of the REALTOR Code of Ethics for members, and state license rules; this series quotes California's.
Accountants and tax preparers: the AICPA Code of Professional Conduct for members, Treasury Department Circular 230 for practice before the IRS, and state boards of accountancy for the CPA title.

What is the same for all six trades?

Under the differences, the method stays the same, and the earlier guides in this series explain each step. Every trade needs a verified Business Profile with the right category, hours and links. Every trade needs one page per service, with the question in the heading and the answer in the first sentence, as our guide to answer-first writing shows. Every trade needs the same name, address, phone and hours on the profile, the website and the structured data. And every trade needs to check its results each month, which our guide to measuring AEO describes.

Google's own guide to its AI features adds one point that applies to all of them: where appropriate, generative AI responses can include information about local businesses, and using products like Google Business Profiles can help your products and services to be visible in both AI responses and other Google Search results. In the end, a trade that keeps its profile complete and its pages honest serves the classic results and the AI answers with the same work.

Where should a trade business start?

Start with what customers see first: the Business Profile and the homepage. The free Get Found Check reads your homepage, the domain settings and the security certificate, and in under 60 seconds it returns a letter grade from A to F with a score out of 100, findings in six areas, three to five quick fixes, a comparison with up to four competitors and a separate grade for readiness for AI assistants. Then open the guide for your trade and work through its pages one at a time.

What does it look like when a page becomes the answer? One example from our own work: VanPlex holds the featured snippet (the boxed result in which Google shows the descriptive text first) and the top organic result, meaning the top unpaid one, on Google for "multiplex developer vancouver". It is a builder and developer site; the method behind it, a clear answer at the top of a page that matches the question, is the one this guide applies to each trade.

One guide for each trade

Each guide below takes one trade and explains which questions its customers ask, where Google and AI assistants show the answers, and which professional and legal rules limit what that trade may write, with the official source for every rule.

Dentists: Which questions patients ask before they book, where Google shows the answers, what the practice pages and the Business Profile must state, and what the American Dental Association's code and the Federal Trade Commission's guides allow a dentist to claim.
Lawyers: Which questions people ask before they call a lawyer, which answer places matter for a firm, what each page and profile must name, and what two states' rules, California's and Florida's, say about websites, past results, reviews and the words a lawyer may use.
Home services: Which questions homeowners ask in an emergency and when they plan a job, which answer places serve each, what Google checks before a trade can advertise, and what one state's license board, California's, says a contractor's website must show.
Restaurants: Which questions diners ask before they choose, which answer places a restaurant meets, how the menu, the hours and the ordering and booking links reach Google, which structured data fits, and which rules limit what a restaurant may claim.
Real estate agents: Which questions sellers and buyers ask before they choose an agent, which answer places matter, what federal fair housing rules and the REALTOR Code of Ethics say about an agent's words and website, and which license details one state, California, requires on every first contact.
Accountants: Which questions clients ask before they hire an accountant, which titles each type of tax professional may use, what the AICPA code and the IRS rules in Circular 230 say about advertising and published fees, and how the pages and the Business Profile should present a practice.
