For a successful website/startup business... Which one should they put more emphasis on?
I always focus on the readers first, as all the SEO in the world is useless if people don't connect with the content. Once content is created with a reader focus, I analyze and edit for basic SEO like keyword content and possible internal/external links. I would rather have 5 targeted readers benefit from my content than 100 unrelated readers who come to my site and bounce.
