As if Twitter needed another problem, a recent survey suggests advertisers are souring on the social media platform.
Advertiser interest in Twitter began cresting early last year, but the latest survey by RBC Capital Markets found a significant jump in the number of advertisers who plan to decrease their spending on the website.
According to the survey, 23 percent of Twitter advertisers plan to decrease spending, while 32 percent plan to increase spending.
"There's a real negative tell in here," RBC lead Internet analyst Mark Mahaney told CNBC's "Squawk Alley" on Wednesday. "Just like there are momentum stock buyers, guess what? There are momentum ad buyers, and the momentum is moving away from Twitter."
In the fourth quarter, Twitter's advertising revenue rose 48 percent year over year to $641 million, below Wall Street's expectation of $647.7 million, according to StreetAccount.
Twitter has faced scrutiny from investors as its user numbers stagnate, leaving Wall Street to wonder where future revenue growth will come from. Shares of Twitter are down more than 23 percent year to date.
