LinkedIn posted its Q3 earnings recently and showed overall strong growth.The subscription and networking website generated $252 million in revenue, much of it from subscription products.Premium individual subscriptions accounted for $50 million, a small portion of overall revenues.However, the more B2B services — Talent (Hiring) Solutions and Marketing Solutions — generated $202 million. And these services include some subscription revenues.In addition, these number represent significant growth for the company. Premium subscription revenue grew by 74% compared to last year’s Q3 results. Marketing Solutions revenue grew by 60%, while Talent Solutions saw an impressive 95% increase.However, the company may be hitting its saturation point in the US market. While membership grew by 43% since the past year, it saw only a 7% increase from last quarter. However, unlike print publications, the site is not limited by geographic boundaries, and there is still a lot of room for growth in international markets.
