Use all the tools Etsy offers, it will give you better odds of getting found. I certainly would not categorize my tags by price. One man may think nothing of a $300 birthday gift while another may only be able to afford a $50 anniversary gift.
Gift for woman or gift for her are both good but you don't want to use them only. Use different tags throughout the listings and see what ones show up in your 30day report. ( Etsy search phrases) those are the ones working for you.
