Hi Chris, you're addressing two issues here, your pricing and your tags. I'm not a big expert in SEO but at a first quick glance, your tags look fine. Your pricing too, but if it's costing you more to make than you are asking for it, something isn't right. Increase your prices by all means, but make some other important changes too! When I look at your shop, I see things that I feel need more attention than your tags or pricing. First, your pictures.
http://www.etsy.com/listing/101076710/felt-owl-plush-owl-ornament-toy-owl?ref=v1_other_2This owl for example. It's such a cute little owl! But photo 1 and 2 are almost the same: out of focus and quite dark, not crisp white and clear. Picture 3 is, well, a bit strange (or is the owl made to hang in your plant?), and totally out of focus. Picture 4 has a tag which I can't read because it's upside down. In other words, work on your photography, because it doesn't do your products justice! There's a lot on the forum on photography, check it out, it's easier than you think :-)
Then the descriptions. I'm staying with the owl here. The first paragraph seems more of a list of tags. The second paragraph doesn't make it much clearer to me. Could be because English is not my native language, but I don't know what a 'party favor is'. And all these capitals don't make it look very professional. Try to describe your product as if you're talking to the customer, instead of writing down all these parts of sentences. And 'My Owls can be made with hundreds of color combinations' isn't very helpful to the customer either. Does it mean I can choose a different color? And if so, which one? Help me make a decision!
I'm sorry if I sound a bit harsh here, but really I'm just trying to help! Because you make such cute items and I hope with a few adjustments you will do very well again! Good luck!
