I would say it depends on

1. how competitive the terms are
2. how common good glossaries are
3. whether or not you have any real value to add

If nobody has a glossary, they are long-tail terms and you are an expert it will have decent value.

If there are dozens of glossaries, it's a mature industry and you have nothing special to add, I wouldn't think there would be much value.
