Help - I'd like to know the answer so I can adjust my key words and do it the proper way.

I use google adwords to help me with key words.  You put in something like "8th birthday cards" and the results gives you a list of words that may apply that were in local searches for the month and in global monthly searches.  It helps to know what words people are using for their searches.
 
example: You will find that hardly anyone searched for 8th birthday card.  From the list I might choose kids birthday cards, or, birthday card for kids, which were used more often.
 
Then use GCU profile of 8 years so you are covered for all of GCU sites.
I also would use 8th in my title.

It's easy to use and a big help for beginners like me.
 
I also found the thread Pamela mentioned very helpful and Tom's post in that thread.
 
Hope this helps.
