Advertisers can increase their bids on ad campaigns and groups depending on how frequently their ads are viewed. Advertisers can grow their bids based on many factors. Advertisers can raise their bids based on high traffic and reduce bids when the traffic is less. For example during weekends or national holidays, people spend more time on the ads hence the ad impression and engagement rate will be higher.
Multi bidding: Rather than bidding on the same campaigns, multi-bidding allows advertisers to bid at different rates on different campaigns.
