I'm building a glossary for a business site and I have a few questions I'm asking myself, maybe somebody here can help me out. The glossary has an index page and each term is on its own page. The definition of each term though is pretty short, usually 100-200 characters. I'm wandering if the content is going to be too thin for google even if these pages are pretty relevant for site's niche. Not that I'm worrying about penalization but I think the glossary is a good opportunity for targeting long tails with unique content and it would be a shame to waste it. I would also have liked to mark it up with something like schema org but it doesn't look like there's any useful type for something like this (apart from general creative work). Any thoughts anybody?
