I use as many words that describe my items as possible in the tags. Anything that someone might be looking for. Think outside the box. If somebody is struggling to find a gift, but have no idea what to get, crazy random things end up in searches. So, be crazy and random - as long as it describes your item, go for it, I say!
Having said that, I was a high school English teacher so words are not a problem for me. Now, photos, that's a different story!
Hope everyone had a great holiday weekend!
