Search engine optimization (SEO for short) is simply the process of obtaining website visitors (or traffic) from “free” or “organic” search results in search engines like Google or Bing. Search engines are important because they provide targeted traffic. Or in other words, search engines allow users at your place what you offer or sell. Targeted website traffic provides revenue and exposure like no other channel of marketing. Compared to other marketing trend SEO is a much higher rate of return.
