fragmentation

Say you have a database with heavy index fragmentation. Say this database also has a lot of free space due to frequent deletes in its data file. This free space is not contiguous.

If I rebuild all indexes to remove fragmentation and then reorganize the database pages so allocated pages and free pages are contiguous, would this cause further fragmentation in my indexes?

I guess the question can be posed as: if it matters, which should I do first, reorganize or rebuild?
