Shunsuke is an advertiser at a kitchen appliance company. He ran an awareness campaign to promote his brand’s award winning toaster. A few months after the campaign ended, he noticed that the baseline performance was overall higher on glance views and conversion rate across many of his products. What is this likely to mean?

The increase in baseline glance views and conversion rate across multiple products, even months after the awareness campaign, indicates a sustained positive impact on brand recognition and customer interest. This phenomenon, often called a "halo effect" or "brand lift," suggests that the initial awareness campaign successfully elevated the brand's overall presence and perception on Amazon. The other options are less likely: a reporting error is possible but doesn't explain the consistent, positive trend; another advertiser promoting Shunsuke's brand is improbable and wouldn't typically result in a broad, sustained lift across his own product catalog; and while category campaigns can drive general awareness, the specific lift for Shunsuke's brand points to his own prior campaign as the primary driver.
