Uber has pulled ads from job search sites such as Hire, and the firm has also announced it will stop offering job search options for people in the US.
The move follows criticism that the companies’ job search software was not as accurate as it claimed to be.
The company said it was responding to “an uptick in false information”.
Uber said the ads would stop working on Thursday, the day before its US launch.
Uber said its job search product, called Hire and the job site for the same name, were both “not a task management tool” and had been removed from the US market.
“Hire was removed from our marketplace as of August 2, 2019,” Uber said in a statement.
“We are taking this action to prevent our customers from inadvertently using these tools to find, interview, and hire people.”
Uber had previously said it would not support search engine advertising unless it received explicit consent from users.
The ad company said the removal of its ads for people who had not been hired would be “an inconvenience to some”.
It said it intended to “review” its ads, and promised that its software would be more accurate and reliable.
The change came as Uber was forced to apologise for misleading job search results, after an investigation by the New York Times found that it had failed to properly vet applicants for jobs.
In a letter to its US customer base, Uber said it had received a “large number of complaints” about Hire.
“To be clear, Hire is not a job search tool,” the company wrote.
“Our Job Search platform does not guarantee a job or position in the marketplace.
Job search and job posting platforms may give you a better idea of whether you are qualified and what your skills are, but they are not a substitute for a job interview.”
The firm said it wanted to “reaffirm our commitment to an accurate and up-to-date job market.”
The company has been under fire in the past for using fake information to attract jobseekers, with many critics saying it was not using the best data available.
It said in April it had lost about $US1.3 billion ($1.7 billion) in revenue in the first nine months of 2018.
The changes follow similar moves by Facebook and Google.
Google said it removed adverts from its search engine, but allowed ads to be placed on its search results pages, including on Facebook.
Facebook has also updated its search advertising platform to remove ads that were posted by third parties.
Users will be able to choose whether or not they want to accept cookies, rather than opting-in to them.
“It’s a change that we’re going to be taking a look at and reviewing,” said an Uber spokesperson.
“The change in our cookie policies is one that we want to make sure we’re making sure is fair, transparent and accurate to our users.”
Uber also said it will make a “small change” to its way it operates when it comes to accepting advertising.
It has said it plans to limit its advertising on its app, including by adding an “invisible” button to the top of the screen where users can turn off ads, similar to how they do now.
Uber did not say how much it was spending on the changes, but a report in the Wall Street Journal said it spent about $3.7 million in 2018 on advertising.
