This chart of SEO attributes is my favorite tool when trying to explain the process and systems in SEO. Search Engine Land is the creator of this infographic and I think it is a great contribution to the trade.
I do believe that it is missing one class of attributes and my favorite way of explaining SEO includes 3 major classes of attributes:
1. What you say about your self (On Page SEO)
2. What others say about you (Off Page SEO)
3. How people vote for your listing (Essentially the CTR when your page appears in the results)
Overall I give the authors an “A” grade for the great work in organizing and communicating a very complex subject in an excellent infographic.
