This is something new to me. I know the wordpress.com account you're talking about but, I never knew you could interact with people inside of this account. Thank you, for sharing!
When you say website, can we share any website? Like for example, can I share my primary website, plus WA affiliate link, or custom landing page?
Anyways, thank you for sharing this information. Unfortunately, I do not know any other free traffic ways besides social media, and right now, I've just been doing Pinterest and that is a job in itself.
