When submitting to search engines, does it matter if you have a space after each comma? Sorry if this is a silly question, I'm just curious if it effects anything :)

Most people add spaces, but I never have and we've still been submitted. The comma is the separation character, space or no space, it reads the next variable keyword.

I'm sure the good search engines will accept either. There may be a few amateur ones that have problems with one format or the other.
