When you post to Instagram, you can set it up to forward the post to Facebook, Twitter and Tumblr. Make use of this! Your audience is everywhere so your social media needs to be everywhere too.
Also, while you post to the different social media platforms, you get to learn more about your audience by how they react or don’t react. For example, if your Instagram posts only get Likes by your mom and yourself, it’s safe to say that the content is not working for you. If you’re not getting the responses that you want, try different things.
My wife was posting promotions for her coaching program and it wasn’t getting much attention. We looked through her Facebook history and realized that she had been posting a lot of the same stuff for over a month because she had a lot of similar programs to promote. I urged her to try something completely different.
She posted a complaint about mothering a teenager which caught a lot of sympathetic comments. She then posted a picture of her looking happy and said something good about her life: plenty more comments. Moral of the story: diversify your posts (and document rather than promote).
Wherever you are in the social media ranking, you can find partners to market with. Seek out other influencers like yourself who have a similar amount of followers. Also look for influencers who are in a synergistic niche. If you’re a chiropractor, then partnering up with an acupuncturist might make sense.
Partnering can mean reposting each others posts, commenting on each others posts or even creating content together. This is especially useful if you’re making videos on YouTube. In the YouTube world, it’s called a collab. The popularity of it is justified.
