Actively participating (aka: not spamming them with backlinks to your content) in LinkedIn groups within your niche and/or location can be a great way to get your name out there and make new connections.
Don’t shy away from starting a new conversation or joining an existing one.
Ask questions, share ideas, or/or provide insights into what’s going on in your industry – it’s an awesome way to show off your expertise and get in contact with like-minded individuals.
The group page on LinkedIn will give you some curated groups right away, so getting started is quick and easy.
