What is the most effective bidding strategy for a new advertiser with limited data on Bilibili's platform?

The most effective bidding strategy for a new advertiser with limited data on Bilibili's platform is a manual cost-per-click (CPC) bidding approach with conservative initial bids, combined with continuous monitoring and optimization. Since there's limited historical data to inform automated bidding strategies, manual CPC allows for greater control over spending and the ability to test different keywords and targeting options. Starting with relatively low bids ensures that the budget isn't quickly exhausted while the system gathers data and identifies effective keywords and audience segments. The advertiser should closely monitor key metrics like impressions, clicks, and conversion rates, and gradually adjust bids based on performance. Once sufficient data is collected, the advertiser can explore more advanced bidding strategies, such as automated bidding or target CPA (cost-per-acquisition) bidding, but the initial phase should prioritize data gathering and controlled experimentation using manual CPC.
