That news headline about presidential candidate Kamala Harris on your Google search results? It may have been written by her campaign.

Harris' team has been launching sponsored posts on Google that link to real news content from various publishers but feature customized headlines and descriptions crafted by her campaign, a practice experts and Google called "common." One sponsored ad that links to NPR’s website features the headline “Harris will Lower Health Costs.” Another that links to the Associated Press reads “VP Harris’s Economic Vision - Lower Costs and Higher Wages.” The advertisements were first reported by Axios.

While these sponsored posts have been used by other campaigns and comply with Google’s policies, some marketing experts worry they could fuel misinformation and distrust in the media. //

Google's ad transparency center shows a number of other publishers featured in Harris ads, including Reuters, Time, CNN, AP, the Independent, the Guardian and USA TODAY.

"We were not aware the Harris campaign was using our content in this manner,” said Lark-Marie Anton, spokesperson for USA TODAY parent company Gannett. “As a news organization, we are committed to ensuring that our stories are shared appropriately, adhering to the highest standards of integrity and accuracy." //

The Harris campaign declined to comment for this story. Donald Trump's campaign did not return a request for comment, but Google's ad transparency center did not show these types of ads from the former president's campaign. //

But even with a sponsored tag, the ads present a “significant ethical concern,” according to Colin Campbell, associate professor of marketing at the University of San Diego.

He said this is especially true when consumers fail to differentiate online ads.

“Many consumers might form opinions based solely on the altered headlines, without ever reading the actual articles,” Campbell said. “Even those who click through and read the articles may feel misled when they notice the discrepancy between the headline and the content, further eroding trust in the media.”
