Suggestion:

/metas/ =>meta blueprint
/categories/ => categories blueprint
/pages/ =>  pages blueprint.

meta_blueprint = Blueprint('metas','__name__', url_prefix='/metas',
template_folder="/path/to/template)

You need to import metas blueprint where you are using url_for
url_for('metas.func_name', _external='True')
This should probably work but I haven't tried.

I have written one such application but under construction, but you can
learn about blueprint from here
