To save database disk space most search engines do not consider common words. However search engines including Google, Yahoo & MSN do not revel the list of Stop words. These stop words also vary in different languages. In my opinion the following keywords are considered Stop words in English, and should be avoided in page titles, headers and links if possible:

A

C
D
E
