The round of optimism comes from BTIG analyst Richard Greenfield and Bernstein Research analyst Carlos Kirjner.
Greenfield forecasts Facebook's revenue is poised to boom in the fourth quarter because more ads are appearing in the mobile news feeds on its application.
"Facebook probably can increase the number of ad impressions per user per day," Kirjner said, "with limited chance of seeing material deterioration in user experience."
For 2014, the analyst expects Facebook will hit revenue of nearly $8.7 billion, surpassing by 7% the consensus estimate for $8 billion.
Bernstein's analyst expects that such news feed ads will be Facebook's main driver of revenue growth.
In September, Facebook unleashed its Gifts service. The gift-giving feature could unlock new forms of revenue as the company experiments with such social commerce that allows people to exchange gift cards.
Starbucks, Magnolia Bakery and 1-800-Flowers were among Facebook's 100 launch partners.
On Monday, Facebook added iTunes digital gifts.
Shares of Facebook have been slowly gaining ground from a 52-week low of $17.55 on an improved advertising outlook for the company.
