Business Networking is a really valuable way to expand your knowledge, learn from the success of others, attain new clients and tell others about your business.
I highly recommend business networking which includes social media platforms like LinkedIn as a way to gain new clients and to build a sustainable business.

You can build your brand. Just like companies build their brands, it's important for you to build your professional brand online. How do you stand out from others in your industry? What makes you marketable? Why should someone pay you six figures?
It can help rank your name on Google. Here's why LinkedIn is important: Ranking on Google's first page can be difficult, but LinkedIn is a well-known and powerful network — and Google's into it. Because of that, it's typically easier to get your LinkedIn page to rank on Google versus your homemade website or online portfolio.
You can research companies. These days, many companies maintain their own LinkedIn pages where they'll update company information, share company news and insight. It can help you tap into industry news.  LinkedIn aggregates a timeline when you log in. There, you'll find news updates from your connections, your groups, and your network. 
Network, network, network! Can we emphasize this enough? LinkedIn is such an important networking tool. Even if you're an introvert and hate networking events, you can still meet potential clients by just been there. 

With a motivated group of business owners comes an abundance of opportunities! There are always lots of opportunities that come from networking and in fact this is where the benefits of business networking are huge!
Opportunities created by networking like joint ventures, client leads, partnerships, speaking and writing opportunities, business or asset sales.
