I am going to go against the commonly prescribed method for attracting clients in Facebook groups of posting 3-5 times a day every day.
If you have something valuable to offer that frequently, then posting is a great idea.
If you are feeling external pressure and just following some arbitrary marketing suggestion without having any strategy for creating content that provides substance or value and connects you to your ideal clients and instead are posting constantly but providing either fluff, information that is not on brand, or just quotes.
It may be time to take a step back and evaluate what your ideal clients need to hear, how you can serve them, and if 1 or 2 posts per day is what it takes to allow you to make the impact you are desiring then honor what feels aligned for you.
I am a big believer in quality over quantity as long as you are consistently visible and giving value. I have never followed .the 3-5 post per day guideline and I have had fairly rapid success in my own business.
Trust your own intuition in what feels right for you and follow your own path to success.
