I rank advertisers based on various factors, including their campaign objectives, budget, target audience, and urgency. Advertisers with larger budgets or more urgent campaigns usually receive higher priority. Nonetheless, if an advertiser with a smaller budget is targeting a specific demographic that aligns with our user base, they may also be prioritized. When arranging the sequence, I consider how relevant each ad is to the accompanying content and the timing of the campaign. For example, seasonal advertisements will be scheduled to coincide with the appropriate festive or holiday periods. Additionally, I review the performance metrics from previous campaigns to inform the sequence, as ads that have performed well and generated high engagement are more likely to be placed in optimal positions or times.
