Advertising delivered through social media or on mobile phones needs to provide clear disclosures and abide by the same requirements that apply to newspaper and television messages, the Federal Trade Commission said.

“Advertisers are responsible for ensuring that their messages are truthful and not deceptive,” the agency said in updated guidelines issued yesterday.

The FTC said it would take enforcement action against companies that violate consumer protection laws.

The guidelines aim to provide practical tools for advertising on smartphones or through social media like Facebook or Twitter.

The suggestions update the “Dot Com Disclosures” guidance the FTC issued in 2000 to cover the rise of online shopping.
