Each photo imported into Lightroom gets at least the following two keywords assigned... “Location” and “Subject”.

"Location" Keyword

One need only assign the lowest level keyword in a hierarchy to have all the levels above it included. Using the above example, if one were to assign the "Beaver pond" keyword to a photo, the "Schwabacher Landing", "Grand Teton" and "Wyoming" keywords will also be assigned to that photo.

"Subject" Keyword

Another hierarchy of keywords that drills down to the subject in the photo. For example: Animals : a-g : Bison

The “Location” and “Subject” keywords provide the ability to quickly search the Lightroom catalog for photos.

As you will see in my workflow description, I also assign a Star Rating to each photo. A Star Rating along with a keyword allows me to create a Smart Collection that will automatically find all of the photos I want to include in my Blog as well as those I want to be "permanent" members of my Collections pages.

More specifically, all photos that have a keyword of "Grand Teton" that have a star rating of 4 will be gathered by a Smart Collection and can easily be included on my Blog  page.

All photos that have a keyword of "Grand Teton" that have a star rating of 5 will be gathered by a Smart Collection and can easily be included on my Collections page for Grand Teton National Park Landscapes.
