1. Online: Start a YouTube channel based on your business. Create a FAQ list from the most common concerns/issues/ challenges facing your target market. Make videos that address those challenges. Use the videos to demonstrate your expertise thru case studies etc. Views and subscribers creates social proof that you can add value to your clients.
2: Offline: create and host a meetup group that serves your target market. Speak on topics from the above FAQ list. Invite other speakers to lead the discussion about 50% of the time. Research meetup.com for more info
3. Use texting software to send review links to clients and networking partners. Asking for reviews on Google, LinkedIn, and other platforms will generate more social proof that you are an expert in your field thus worthy of hiring and paying top dollar.
I have used these techniques in my business and they kept my phone ringing off the hook before, during, and after the COVID lockdown. Feel free to setup a call with me if you want more specific action steps.
