Without seeing what you see, can't really tell you. What I can say is that rebuilding indexes does not eliminate fragmentation, it reduces it.

Cool

Index rebuilds aren't expected to make the fragmentation exactly zero. Also could be index is too small to be worth rebuilding.

To add to what the others have already cited... fragmentation is constantly happening on active systems that have any indexes that are based on non-temporally related columns... even during defragmentation if done online.

--Jeff Moden

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair
