Yes, if one places the symlink in some another dir than the
target then the size increases.

Observe

$ cd
$ mkdir -p test/sl
$ cd !:2
$ touch a
$ ln -s a b
$ cd
$ ln -s test/sl/a l

then compare

$ du -b test/sl/b
1       test/slb/

$ du -b l
9       l

Lesson: There is a lot of space to save by placing symlinks correctly!
