Good Afternoon, and thanks for inviting me to join this panel!
A bit about me, I run a blog www.edgeoftheplayground.com and also a medium sized Facebook page. I am an autistic adult and share my experiences as someone who is on the autism spectrum in order to help other autistic people, families, and other autism allies. I have had the privilege to be on a couple of cake panels here as well hosted by @apm including how autism presents differently in women. I have also written several posts that have been featured in The Mighty, Mental Health Talk, and others.
I have found across platforms that engagement is very important in promoting both my message online and speaking engagements I do within the community offline. I do my best to always make my followers or anyone reading feel like they are part of a community. I promote positivity but also honesty in my posts so that they are authentic. When people see you are authentic they will engage with you. Be yourself online, don't attempt to be what you think will trigger an algorithm or more views, if you are yourself then those things will eventually come. Write about things you are passionate about.
Positivity also helps with engagement, because you want genuine people to engage with you. Build and reach out to the type of people you want as a part of your community. Think about who it is you are trying to reach and then always keep them in mind as a real person whenever you are creating content. Think about who they are, what their life may be like, and what they would find most helpful. Also do your best to respond to comments, even if it just a "like" to let people know that you are reading. While it does not have to be every single comment, going through several will show people who are following that you care about their story and experiences too. This makes it more of an interaction, and you are then more of a real person to them that they want to engage with.
Overall, be yourself. You will eventually attract engagement. It is better to grow more slowly and find a genuine, authentic audience than try to use marketing or social media tactics to grow engagement quickly. You will end up with the same numbers and those people will stay because there will be a real connection and they will want to interact with you.
