ChatGPT Ads Context Hints for Local Service Businesses: Examples by Trade

KEY TAKEAWAYS
- Context hints describe what you offer, who it helps and when it is useful; they are not keywords and not targeting rules.
- One specific idea in a natural sentence beats a list of terms; OpenAI's own local plumber example names a city and a service-call fee.
- Hints cannot restrict where or when ads show, so set location in the campaign, which reaches down to ZIP code in the US.
- Organize hints by ad group, one service or customer need each, with its own ads and landing page.
- Keep hints accurate and update them the day prices, hours, services or service areas change.
The short answer
A context hint is a short, plain-language description you add to a ChatGPT Ads ad group to explain what you offer, who it helps and when it is useful. ChatGPT reads your hints alongside your ad, your landing page and the conversation to judge whether your ad is relevant. A good hint is one specific idea in a natural sentence, such as after-hours residential plumbing in your city with a stated call-out fee. A list of keywords is a weak hint.
What context hints do, and what they don't
On Google you choose keywords and the ad can show when someone types them. ChatGPT has no keyword list. It matches ads to the context and intent of a conversation using several signals: the conversation itself, your landing page, your ad's headline and description, your context hints and, where ads personalization is on, some signals from the person's wider use of ChatGPT.
Context hints are the one signal you write purely to explain yourself. OpenAI's guidance is that they should add something the ad and page do not already make clear, and that they should be specific, relevant and accurate.
They also have limits that catch people out. Hints are not exact-match keywords, they do not guarantee your ad appears in any conversation, and they cannot enforce geography, schedules or exclusions. OpenAI draws the line this way: a hint saying you offer residential plumbing in a city describes the business, while a hint asking for the ad to show only to people in that city is an instruction it will not follow. Location belongs in the campaign's targeting, which reaches down to ZIP code in the US.
The three questions a good hint answers
OpenAI frames hints around what, who and when. A single hint does not need all three. Most good ones answer one of them well.
| Question | What it covers | Example hint |
|---|---|---|
| What | Services, features, pricing, availability, service area | Same-day water heater replacement with parts and labor priced up front |
| Who | The customer need or circumstance you suit | Homeowners in older houses that still have two-prong outlets |
| When | The situation or decision where you help | After a storm, when shingles are missing and the ceiling is leaking |
Weak hints and strong hints, by trade
These examples are illustrative. Use details that are actually true of your business, including your real prices and service area. A hint that claims something you do not offer hurts you twice: once in relevance, and again at ad review, which checks your ad against your landing page.
Plumbers
Weak: plumber, plumbing, emergency plumber, drain cleaning. Strong: after-hours residential plumbing in Albany with a flat service-call fee for urgent leaks. Strong: help deciding whether to repair or replace a water heater more than ten years old. Strong: sewer camera inspections for buyers before closing on an older home.
HVAC
Weak: HVAC, furnace, AC repair. Strong: same-day furnace repair for homeowners whose heat stopped during a cold snap. Strong: heat pump installation for homes moving off oil heat, including help with rebate paperwork. Strong: fall furnace tune-ups booked online before the heating season starts.
Roofers
Weak: roofing, roofer, roof repair. Strong: storm damage roof inspections with photos you can send to your insurer. Strong: asphalt shingle replacement for roofs more than 20 years old, with a written estimate within 48 hours. Strong: ice dam removal and leak repair during winter.
Electricians
Weak: electrician, electrical services. Strong: panel upgrades for homeowners adding an EV charger or a heat pump. Strong: replacing old wiring and two-prong outlets before a home sale or insurance inspection. Strong: standby generator installation for houses that lose power in winter storms.
Landscapers
Weak: landscaping, lawn care, hardscape. Strong: paver patios and walkways designed and installed in a single season. Strong: weekly mowing at a fixed monthly price for homeowners who do not have time for the yard. Strong: spring cleanup for yards still covered in leaves and debris from winter.
Other local services
Cleaning: move-out cleaning for renters who want their security deposit back. Pest control: same-week treatment for mice getting into a house in the fall. Auto repair: check engine light diagnosis with the fee credited toward the repair. Movers: local moves within the same city booked on short notice.
Look at what the strong hints share. Each one describes a real situation a customer would put to ChatGPT in their own words. Nobody asks an assistant for HVAC. They ask what to do because the furnace stopped and it is ten degrees outside.
How to organize hints across ad groups
Hints live at the ad group level, so they should match that ad group's focus. OpenAI's own example is a plumber with separate ad groups for emergency repairs and preventive maintenance. Put the after-hours hints in the emergency group, with ads about speed and a landing page with the phone number at the top. Put the maintenance hints in a separate group, with ads about scheduling and a page built around a booking form.
Related situations can share a group. A furnace that will not start and a furnace making a banging noise are both repairs. A new heat pump is a different decision that needs a different page, so it gets its own group. If two hints would need different ads or different pages, they belong in different ad groups.
Write several hints per group, one idea each, and pair them with several ad variations that take genuinely different angles. OpenAI recommends volume and variety in creative so the system has more chances to find a conversation your ad fits.

Keyword lists
A list of terms adds nothing the system cannot already read on your page. Describe the situation instead.
Hints that wish rather than describe
OpenAI makes the point directly: wanting to reach a group of people does not make your offer relevant to them. Busy professionals is not a useful hint unless your service suits them for a reason you can state, such as evening and weekend appointments.
Stale details
If your price, hours or service area change, update the hints the same day. A fee in the hint that differs from the fee on the page is the kind of mismatch that hurts both relevance and review.
Using hints as targeting
A city name in a hint describes you; it does not stop the ad running elsewhere. Set the location in the campaign.

Frequently Asked Questions (FAQ)
Q: Are context hints the same as keywords? A: No. Keywords on search platforms trigger an ad when someone types them. Context hints describe your business so ChatGPT can judge relevance, and people do not need to use the words in your hint for your ad to be relevant.
Q: How many context hints should an ad group have? A: OpenAI does not publish a number. Write enough to cover the distinct situations that ad group serves, each as one clear idea, and split the group when situations need different ads or pages.
Q: Can I put my city in a context hint? A: Yes, as a description of where you work. It will not restrict delivery. Use the campaign's location targeting for that, which supports states, cities, markets and ZIP codes in the US.
Q: Should I include prices in context hints? A: If they are accurate and matter to the customer's decision, yes. OpenAI's own local plumber example includes a service-call fee. Keep the figure identical to what your landing page says.
Q: Do context hints guarantee my ad shows in certain conversations? A: No. They inform relevance. Whether your ad shows still depends on the conversation, your ad, your landing page, your bid and the competition.
