A campaign is not getting the expected results: ad impressions are not increasing. Why is this happening? Select All Correct Responses

The correct answer encompasses all options because ad impression issues are rarely due to a single factor. A lack of daily budget directly limits how often your ads can be shown. Publications with uncompetitive prices or unattractive titles will have lower click-through rates and conversion rates, causing the algorithm to show them less frequently. A low target ACOS (Advertising Cost of Sale) can restrict your bids, making it harder to win ad placements and thus reducing impressions. Because these factors interact and campaign performance needs time to stabilize and gather sufficient data, it's crucial to allow campaigns to run for at least 30 days before making definitive judgments or significant changes.
