Spell check for SE ranking and more money
For the past week or so I’ve been using the latest BETA to the Google toolbar. The #1 greatest feature it has is a spell check that lets you spell check any web form. During that time I have noticed that my adsense revenue has increased. So I started to think about what I may have been doing to increase that revenue and the only big thing I could think of was spell checking most of my blogs and wiki content. You might task why spell checking web pages help so much for this, well I really don’t know, but I have a theory.
If search engines are looking for the most relevant keywords in your content, then they have to be looking for words that are both unique and words that are repeated often, while overlooking dead words like is and the. Once that list is compiled of interesting words the web master hopes that the keywords they are targeting are in that list. Well, misspelled words may end up on that list as either being unique or in my person instance, repeated often 
When you use spell check and get all the words spelled correctly you end up doing two things, putting more relevant keywords on the unique and interesting list and you allow more people to search for your pages as they are most often searching on correctly spelled words. Then next step of this is the targeted advertising side. Once your keywords are spelled correctly and the unique and relevant list of keywords is better, then the keywords for thetargeted advertising will match your site better as well. Meaning more and better keywords for the ads
