Make sure you give people a reason to follow you - Facebook, LinkedIn, Instagram, Twitter - and keep it professional and up-to-date.
Does your Facebook page have a URL/Username? This makes it much easier to promote your page (instead of saying "Find us on Facebook..." you can give people the exact URL - facebook.com/CatrinaOssmann). Learn more.
Try something new! Try a live broadcast to announce an event, special sale, tips or news. Promote it really well (reminders about the day/time, emails...), or offer an incentive for those who share and/or participate.

Make sure your information is up to date. You could have someone who wants to email or call you, or send a referral your way - make sure they can easily get in touch with you.
Try a post instead of an update. This is a longer "blog type" post. Your connections will get a notification about your update. If you're already adding new content to your website, or other social media accounts, you can re-purpose the content and post it on LinkedIn.
Download a copy of your connections. Those connections from old jobs, or who you went to school may be good leads, or can help connect you to someone else. Get the list and reach out to a few of those people to catch up.
