I break SEO up into twelve distinct types. Some of these types could legitimately be seen as subtypes, however I find it useful to look them separately.
1.Authority SEO
Authority SEO consists of making yourself an authority in a given niche or particular topic in order to increase your rankings.
2.LSI SEO
This consists of understanding how Google uses words related to the search terms in calculating the relevance of the search results.
3.Site-Wide SEO
This refers to techniques used to improve your SEO standings that are applied across your entire website.
4.On-Page SEO
This refers to SEO techniques that apply to the content on one particular page.
5.Blogging SEO
this refers to techniques which use blogs and blogging to improve your search standings.
6.Local SEO
This refers to SEO techniques that are particularly useful when promoting a website that is associated with a local business or organization.
7.Search Results SEO
This refers to things you can do to improve the way your site appears within the search results. The other types of SEO focus on changing where you appear within the search results. This type changes what the search result listing for your site looks like.
8.Off-Site SEO
While this version does break this down a bit more than the previous one, I considered breaking up this category even further because it contains so much. This type of SEO includes things that you do outside of your website in order to improve your standing on the search results pages. For the most part this consists of ways and places to get links from other websites to your website.
9.Viral SEO
Viral SEO consists of techniques used specifically to cause people to share and re-share your website content. When this is done well the sharing can multiply exponentially.
10.Social SEO
This refers to specific techniques to promote your site within social media such as Facebook, Google+, and Twitter.
11.Video SEO
This refers to techniques which use videos to improve your traffic and search standings.
12.Press Release SEO
Finally, this refers to techniques using press releases to gain additional traffic authority and to improve your standings in the search results.
