OK, which is better Cadillac, Cadillac Seville, Cadillac CTS, Cadillac Escalade -or- Cadillac, Seville, CTS, Escalade ??? Also --- how do you seperate Keywords? A comma, colon, space, ??
I separate them using commas, as to the best choice i would go with the first option because that way you target long keyword and also get results if partial. Cadillac Seville ( longer keyword )
