I thought I should broach the subject of creating plural keywords in title, text & links. While I notice search engines, like Yahoo, will utilize/extract the singular portion of a plural keyword in a search query of the word, I tend to use plural keywords, i.e. -
"Beauty products supplies stores", instead of "Beauty product supply store". While I know that this can give text links or titles a degree of incorrect grammar, it does tend to cover all bases.
So I ask - do you post your keywords within titles, text & links in the singular or plural?
