Thanks for reaching out!
Some awesome advice above! In addition to understanding your Segmentation, (who are you targeting? are you focused towards a specific Industry? What is your differentiator?) Now is a really good time to build your network through online forums such as LinkedIn or other social networks that your Customers may be part of. I have seen a bunch of really good networking events and webinars pop up over the last few weeks, is there an opportunity to look at attending, supporting or speaking at to raise your profile?
LinkedIn Learning offers free courses on both marketing and how to use the platform that may be useful and I saw that Robett Hollis (https://www.linkedin.com/in/robett/) posted this morning on LinkedIn that he was running a free webinar on how to get the most out of LinkedIn that may be worth checking out.
Please let me know if I can help with anything further!
