How do I know if my context hint is working?

Watch impressions and relevance in the Ads Manager. A hint that's too narrow shows almost never; one that's too broad shows often but converts poorly because it's matching unrelated conversations. Both are signals to rewrite it, not to walk away.

Should I write a different hint for each product?

For each audience, not each product. If one product serves two clearly different buyers, that's two ad groups with two hints. If it's genuinely one audience, one sharp hint beats several vague ones.

What's the single most common mistake?

Describing the product instead of the buyer. "AI invoicing software" tells ChatGPT what you sell, not who's in-market for it or why. The fix is almost always to lead with the person and their situation, and let the product stay implicit.

How-To

How to Write a Context Hint That Actually Gets Shown

Four rules, good-vs-bad examples, and a checklist — for when you'd rather write it yourself than generate one.

1. Start with the moment, not the product

The instinct is to describe what you sell. Resist it. Describe who's buying and what they're doing right now — comparing options, hitting a specific wall, about to make a decision. ChatGPT already knows what your ad is for once it's approved; the hint's job is to find the right conversation to put it in front of.

2. Be specific, not broad

"People interested in productivity tools" describes millions of unrelated conversations and matches almost none of them well. "Solo founders comparing project-management tools because their team just grew past five people" describes one clear situation — and it's the specific version that actually triggers. Specificity isn't a stylistic choice here; it's the mechanism.

3. Keep it to one or two sentences

Once a hint tries to list every possible buyer or every possible use case, it stops describing anyone in particular. If you're tempted to add "and also," that's usually the sign you need a second ad group with its own hint, not a longer sentence.

4. Don't keyword-stuff it

Context hints are matched by meaning, not text, so stacking synonyms or repeating your product category doesn't help the way it would in a search campaign — it just makes the sentence read worse. Write it the way you'd describe the buyer to a colleague, not the way you'd fill in a keyword list.

Good vs. bad

Too broad

“Businesses looking for software to help with invoicing and payments.”

Specific

“Solo founders and small agencies evaluating AI tools to automate client invoicing, payment reminders, and late-fee tracking without hiring a bookkeeper.”

Checklist before you save it

Names a specific audience, not a broad category
Describes a situation or trigger, not just a product category
Reads as one or two sentences, not a list
Has no repeated or stacked synonyms
Would make sense read aloud to a colleague
