Is this reader magnet good enough?

Hi,

First time poster here. I created a reader magnet at

pages.sarahvigue.com

and I just can’t tell if the reader magnet is good enough. I’ve had some subscribers but I’m not sure really how to gauge if I’ll have success or not.

I wrote a memoir and want to build my platform and the memoir is about my testimony and why it mattered so much to me so the reader magnet and on the importance of sharing your testimony.
