I checked out doodlekit.com and the free progam does not have
SEO included. What is that supposed to mean? It doesn't allow for meta tags? I found that confusing.

I was under the impression that
SEO is more of a process of different methods to increase site traffic (i.e. blog, content, keywords, sites linking back to your site, ect...) rather than an available option.
I'm not sure what they mean by that, but if they have those type of capabilities, I would choose the plan for only $14 that includes
SEO capabilities. Just a thought.
