Adding service keywords allows you to further refine any type of service that you have selected in the advanced search.
For example, lets say that you would like to find a Swedish Massage. Select "Massages" from the service pull-down, type the word "Swedish" into the Service Keyword text box, and click search.
Now you can solely browse Swedish Massages without having to see Shiastu, Hot Stone, etc. Delete your keyword in the Search Results appointment filter and you can see every massage offered on Lifebooker.
