LinkedIn is free if you just want a basic account. The basic account has features that offer a good base for marketing your company. With the free account, you can build your professional footprint, network with people you know and should know, and search for companies or people.
When first starting with LinkedIn, the free account will do. But taking your business to the next level might require upgrading your account. Paying for an account on LinkedIn is recommended when you’ve maxed out the utility of the features of your free account and need more powerful tools.
