What SEO Is
Search Engine Optimization refers to the collection of techniques and practices that allow a site to get more traffic from search engines (Google, Yahoo, Microsoft). SEO can be divided into two main areas: off-page SEO (work that takes place separate from the website) and on-page SEO (website changes to make your website rank better). This tutorial will cover both areas in detail! Remember, a website is not fully optimized for search engines unless it employs both on and off-page SEO.
What SEO Is Not
SEO is not purchasing the number #1 sponsored link through Google Adwords and proclaiming that you have a #1 ranking on Google. Purchasing paid placements on search engines is a type of Search Engine Marketing (SEM), and is not covered in this tutorial.
SEO is not ranking #1 for your company's name. If you're reading this tutorial, you probably already know that ranking for popular terms is darn near impossible, but specific terms, such as a company name, is a freebie. The search engines usually are smart enough to award you that rank by default (unless you are being penalized).
Who Uses SEO
If a website is currently ranked #10 on Google for the search phrase, "how to make egg rolls," but wants to rise to #1, this websites needs to consider SEO. Because search engines have become more and more popular on the web, nearly anyone trying to get seen on the web can benefit from a little SEO loving.
