Google search does some interesting stuff right in front of our eyes, but most Affiliates don't seem to notice its significance. This ingenuity affects site rankings in search engines which determine whether or not you will receive thousands or hundreds of visitors a day.

Have you noticed what happens when a Google search is made for "affiliate" but is accidentally typed "affilaite"? You see a question...Did you mean: affiliate? This is because Google and most other search engines use spell checking systems and can quickly tell you how many pages contain a particular misspelled word. The bottom line is that most, if not all search engines think correct spelling is important and can easily factor this into its ranking algorithms. Research shows that the pages at the top all have one thing in common: good writing with correct spelling.

Actually, I quite disagree with you to a certain extent... typos aka mispelled words do generate quite a bit of traffic because there are loads of people who incorrectly spell a word...
Sure Google is going to ask you if you meant this or that but many times search queries contain no space, misspelled, or completely F#@*ed U# while typing and entering.
I get tons of traffic from typos....
