Craig R. Pennell helped me to get a website set up and can’t recomment working with him for a few hours to get a wordpress site set up correctly — huge time saver and worth every penny.. But a CTA is free — it is a Call To Action — basically a way to keep readers reading your work — On my articles they are the One More Thing at the bottom that leads to my website so they get all my new articles and a few guides on creativity. Best of luck and keep at it.
