Hi Marta Brzosko! :) That’s true. However, SEO is way more difficult to understand for most new writers/bloggers than building an email list. Additionally, even if you understand it, unless you are an expert, you will have a hard time to rank on Google if you write about popular topics :)
I do use SEO and I get a lot of external views through it but I know from my coaching clients and other bloggers that it’s not easy to understand and apply right from the beginning.
