Cramer: A gigantic game-changer for LinkedIn

Cramer's Mad Dash: Huge fan of LinkedIn

Expanding into China would represent a "gigantic game-changer" for LinkedIn, CNBC's Jim Cramer said Friday.

BMO Capital recently upgraded its rating on LinkedIn to "outperform" from "market perform" because it believes the professional social networking site plans to break into China. Cramer said he's a "huge fan" of LinkedIn, lauding it for its subscription services and advertising model.

"People felt the last quarter was weak," Cramer said on "Squawk on the Street." "I thought it was terrific. They're spending a lot to dominate the world. Moving into China is a gigantic game-changer for them, it's like Coach going in there with handbags."

Cramer also said strong showings from other big-name social media companies, such as Twitter and Facebook, indicate that the stocks could all outperform on Friday.
