A "grant-trend" weekly post on LinkedIn is an excellent idea for a "show and tell" approach that can cut through the noise and demonstrate your value. It's a fantastic way to build authority, attract potential clients, and educate your audience. Here's how to make those weekly posts "do wonders" and ensure they don't go unnoticed:
