I review the campaign objectives, conversion events and organization of campaigns and ad sets. The structure needs to support meaningful decisions without dividing the budget into more tests than it can reasonably support. Budget allocation follows the priorities we agree and the evidence available.
Creative testing compares messages, product or service presentations and formats. A useful test asks a specific question, such as whether the offer is clear or whether an advert attracts the right kind of enquiry. I review performance alongside the landing page instead of assuming every weak result is an audience problem.
Audience choices and suitable retargeting depend on the business, available data, platform rules and consent requirements. I do not promise that audience settings can precisely identify ethnicity. For language-specific campaigns, creative and website experience are as important as the available settings.
