One very interesting thing I learned recently is about case-sensitivity. If a user does a search on the word “Design”, for example, most search engines will search for Design with an uppercase “D” ONLY. So if you’ve used “design” as one of your keywords then you may not be found! Alternately, if a user searches “design” and you’ve used the keyword “Designer” most engines will recognize words of any case if the search is done using all lower case letters. So make sure your website uses keywords and phrases in uppercase or starting with an uppercase letter.
