To clear my question:
1. By level I mean the depth of the directory.
e.g. domain.com/animals/pets/dogs/dog-health is level 4 deep
2. From all the info I read on themes they suggest after level 3 the 4th level must be sub domain
3. But our site is all on one domain and it is already level 10 deep. If we accept the suggestion we'll have to shift all our existing pages from level 4 and onwards to new sub domains. So is it really required to have sub domains to rank well? Can't I have a say a 30 level deep site and still rank well?
