It was just a matter of time before Twitter increased the amount of ads in its feed and applications. Twitter announced on Monday that mobile users would start to see promoted tweets right in their timelines. Promoted Tweets are a way for advertisers to get themselves in front of more Twitter users, and a way for Twitter to make money. This change is not surprising now that Twitter has public stockholders to please. It’s common knowledge that ads that are set apart tend to be ignored, so putting Promoted Tweets right in the feed is a way to increase the performance of those ads.
