Adelaide is an attention-based advertising measurement and optimization platform that helps advertisers and publishers understand and improve the quality of ad impressions. The company pioneered the Adelaide Attention Unit (AU), a metric that measures the attention an ad receives based on factors like viewability, size, position, and engagement. Adelaide's platform enables advertisers to plan, buy, and measure media based on attention rather than traditional metrics like impressions or viewability alone. Adelaide works with major brands, agencies, and publishers to optimize media investments by focusing on attention quality. The company has established itself as a leader in the attention metrics movement within digital advertising, providing tools that integrate with major DSPs and ad platforms. Adelaide's approach helps advertisers reduce waste, improve campaign performance, and make more informed media buying decisions by prioritizing placements that generate higher attention from audiences.
