Google+ is a social media platform owned by Google with over 1.15 billion active users globally and 2.2 million in India. While integrated with other Google products, it is not as widely used as Facebook and sees little engagement from younger users, averaging only 7 minutes a month of user time. However, it can be useful for businesses for search engine visibility, connecting with targeted circles, and leveraging features like Hangouts for video calls and online events.
