As a companion to the table, Search Engine Land’s Guide To SEO explains the ranking factors in more depth, in a tutorial providing tips and advice on implementing them.

You can view a condensed version of the SEO Table explained in a quick presentation format here:

Search engine optimization (SEO) is the process of affecting the visibility of a website or a web page in a search engine's unpaid results - often referred to as 'natural,' 'organic,' or 'earned' results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users. SEO may target different kinds of search, including image search, local search, video search, academic search,[1] news search and industry-specific vertical search engines.

As an Internet marketing strategy, SEO considers how search engines work, what people search for, the actual search terms or keywords typed into search engines and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content, HTML and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic.

Digital marketing is a term that has been around for quite awhile but hasn’t been very well defined, encompassing things like banner advertising, search engine optimization (SEO) and pay per click. Yet, this is too narrow of a definition. What about email, RSS, voice broadcast, fax broadcast, blogging, podcasting, video streams, wireless text messaging, and instant messaging? You get the idea. To clearly define what digital marketing is let’s talk about what it is not. For starters, it does not include more traditional forms of marketing such as radio, TV, billboard and print because they do not offer instant feedback and report. Sure, some people may respond to a call to action from an advertisement in one of these mediums but there is no way to know the exact number of people who saw or heard it. Such data is collected (and still then just educated guesses) long after the initial ad impression is made. Yes, convergence has made television at bit more interactive, with devices such as TiVo able to record viewer statistics like those for Web sites, but there is still a long way to go. With digital marketing, however, we’re already there.
