Jokes, emotional images, and interesting videos will draw people's attention and will make them more inclined to interact with your page.
Try not to post actor-related posts constantly.
People will start to find it boring and will ignore your posts. If you find something that is powerful, engaging, and relatable you can post it or share it and interact with your audience when they react to it.
If you post something engaging enough, others will start to share it- gaining more traffic to your page. This new audience will then see what you have been doing with your acting work and start following you as well.
A good trick for this is: When you find an engaging picture of video, download it to your computer. When you post it, tag the person who originally posted it.
When your fans share it, your page will come up as where the video lives and that is how more traffic will be driven to your page.
Remember to post tasteful content!
