How to Write ChatGPT Ads Context Hints: 20 Examples by Industry

Weak vs strong ChatGPT Ads context hints for 20 businesses, with the simple pattern behind every good one.

Most first attempts at context hints look like keyword lists: "plumber," "CRM software," "dog bed." They're short, vague, and they tell ChatGPT Ads almost nothing about when your offer actually helps someone.

This guide shows 20 real-world style examples, each as a weak version and a strong rewrite, so you can see the pattern and apply it to your own business. If you're new to context hints, start with the complete guide to ChatGPT Ads context hints.

The pattern behind every strong hint

A strong context hint describes at least two of these three things:

The offer: what exactly you sell or do
The customer: who it's for
The moment: the situation that makes someone need it

OpenAI's guidance asks for clear, specific, natural-language descriptions that add information your ads and landing pages don't already make clear. Context hints are not exact-match keywords, so writing them like keywords wastes them.

A quick test: read your hint out loud. If it sounds like something a customer might actually be dealing with, it's on the right track. If it sounds like a search term, rewrite it.

Home services

Business	Weak hint	Strong hint
Plumber	plumber	Emergency pipe repair for homeowners when a burst pipe is flooding the basement
HVAC	AC repair	Air conditioning repair when a home's AC is running but blowing warm air
Roofer	roofing company	Roof leak repair after a storm leaves water stains on the ceiling
Electrician	electrician near me	Electrical panel upgrade for older homes adding an EV charger or new appliances
Pest control	exterminator	Mouse removal for homeowners hearing scratching in the walls at night

Why the strong versions work: each one names a specific service and the exact moment a homeowner realizes they need it. That's the situation people describe to ChatGPT.

Professional and local services

Business	Weak hint	Strong hint
Personal injury law firm	car accident lawyer	Personal injury representation for drivers whose insurance company is offering a low settlement after a crash
Estate planning attorney	wills	Wills and living trusts for young families who want guardianship for their children in place
Accountant	CPA	Bookkeeping and tax filing for freelancers who just received their first 1099s
Auto repair shop	mechanic	Brake repair for drivers hearing grinding or squealing when they stop
Moving company	movers	Local moving help for families relocating within the same city on a tight timeline

Note for regulated industries: OpenAI approves legal, health and financial advertisers case by case. Keep these hints factual. Describe the service and the situation, never an outcome like "win your case" or "guaranteed results."

Write context hints for the moments your customers need you.

Dental and health

Business	Weak hint	Strong hint
Family dentist	dentist	Family dental practice accepting new patients for people who recently moved to the area
Orthodontist	Invisalign	Clear aligner treatment for adults with mild crowding who want to avoid metal braces

Ecommerce

Business	Weak hint	Strong hint
Dog bed brand	dog bed	Washable orthopedic dog beds for older dogs with stiff joints
Luggage brand	carry-on bag	Carry-on luggage that fits under the seat for travelers who want to skip checked bags
Coffee brand	coffee beans	Low-acid coffee for people who love coffee but get stomach discomfort from regular roasts
Kids' gear	water bottle	Leak-proof kids' water bottles that won't spill inside school backpacks

Why the strong versions work: ecommerce hints do best when they name the problem the product solves, not just the product category.

B2B and software

Business	Weak hint	Strong hint
CRM	CRM software	Simple CRM for small sales teams that keep losing track of follow-ups in spreadsheets
Inventory software	inventory app	Inventory software for small retailers who keep running out of best-selling items
Scheduling software	booking tool	Online booking for salons and barbershops tired of managing appointments by phone and text
Payroll service	payroll	Payroll for small businesses hiring their first employees and worried about getting taxes right

Five rules to apply to your own hints

Only describe what's true. If you don't offer same-day service, don't write "same-day." If you don't serve commercial clients, leave them out.
One moment per hint. "Burst pipe" and "slow drain" are different situations. Give each its own hint.
Skip city names. A hint can't restrict where your ad shows. Use the campaign's location targeting instead.
Vary the wording. Ten hints that all start with "homeowners in..." add little. Each hint should describe a different situation.
Keep a master copy. Updating an ad group's hints replaces the whole list, so keep every hint in a document outside Ads Manager.

How many hints should you start with?

OpenAI allows up to 2,000 context hints per ad group, according to its campaign targeting documentation. You don't need anywhere near that. Start with 3 to 5 strong hints per ad group, one ad group per customer need, and add more once you see which needs bring in leads.

If you want to know exactly which hints book calls, the Big Hint Campaign method gives each key hint its own ad group so you can compare them side by side.
