01 / Creative research

Turn the unknowns into a research plan.

01

Check the acquisition promise

Read the store headline, screenshots and description. What problem is the app promising to solve?

Study the storefront
02

Look for ad evidence

Explore apps with direct store-link matches. Compare their hooks and formats without assuming the same approach works here.

Browse observed advertisers
03

Separate demand from paid growth

Store rankings and revenue estimates describe market context. They do not establish ad spend, conversions or ROAS.

Review the market context

02 / Storefront & product

Where the click lands.

Study the product story and store experience behind the acquisition funnel.
