Right over my head. Why does log-structure help anything?

Log structured disk layouts allow for better placement of writeout, so
that you cn eliminate most or all seeks. Seeks are the enemy when

google on log structured disk layout, or somesuch, for details.

I understand what log structure is generally, but how does it help swapin?
