Native advertising is a relatively new form of online advertising that matches the format of surrounding non-advertising content. The fact that native advertising blends into its context risks deceiving consumers who may be unaware the content they are viewing is actually advertising. Article-style native advertising, a native ad form that mimics the style of online news articles, is particularly concerning since consumers may not expect advertising to appear in such a format. Such concern is supported by research finding low efficacy of traditional disclosures on article-style native advertisements. We investigate a novel means of increasing ad recognition through the use of companion banner advertising. Across two experiments we demonstrate that inclusion of a companion banner boosts consumer recognition of the paid nature of article-style native advertising to the same degree as a traditional disclosure. In both cases we also find that the negative reactions caused by ad recognition are muted when a native ad is perceived as having higher sponsorship transparency. These effects occur for both familiar and unfamiliar brands. Taken together, results not only detail the efficacy of a new means of achieving adequate disclosure, but also develop greater understanding of how consumers respond to article-style native advertising. •Recognition of native advertising can be triggered by companion banner advertising.•Companion banner advertising results in the same ensuing effects as text disclosure.•Companion banner advertising is effective for both familiar and unfamiliar brands.•Perceptions of sponsorship transparency mitigate negative effect of ad recognition.
