Example- Keywords: baseball caps, baseball shirts, baseball gloves
URL setup- baseball caps --> mybaseballcaps.com baseball shirts --> baseballshirtsnow.com etc.
have all keywords (baseball caps, baseball shirts, baseball gloves) point to the same MAIN domain --> baseballstuff.com
As stated above, I already purchased these domains with my keywords in it. My opinion is that having one domain which receives ALL the link juice and authority would be better than having multiple keyword rich domains with a little link juice for just that particular keyword its optimized for. From what I hear, keywords in the URL don't matter as much anymore for what I was trying to do with them when I purchased........unfortunately, but would love to hear opinions.
