I'm having trouble finding a reputable SEO service. I'm looking for a service to increase my page rankings, BUT I don't need content because I plan on doing the writing myself. Most of the services I've found seem to be either selling content creation or sketchy PBN links. I have three questions. 1. Do I even need an SEO service, or should I just keep writing articles on my site and let it grow the natural way? 2. If I do need SEO, what type should I use to keep my site clean? 3. Are high authority blog posts on Huffington post etc worth it?
