Google does not make any difference between lower-case and upper-case letters.

Example : Directory = DIRECTORY = directory = dIReCtORY

With Google, as far as the search algorithm is concerned, if one letter is different, the results of the search will be different. Thus a singular word will be different from the same word in the plural.
Example : engine is different from engines

cooluks put it well. there is no difference.

could you imagine the search engine nightmare if variation such as case mattered... scary thought.

lower case and upper case doesn't have any effect except for plural and singular...

I don't think so.SE's look more towards the terms used rather than the case of the word. For example if you type in "Affiliates And Their Commisions" or "affiliates and their commissions" the results are the same in Google.

John, LOL. Yea thats me

I'll get the suit & tie out for the next shot

marketraise corp,

Not sure about the the plural forms I have several sites I rank #1 for the singular and #3-#10 for the plural form.. same word...

So i believe they are still different.

in addition to what i've said take time to study about when to use an 'under score' and a hyphen with your keywords...
