Hi Amy
Some of this is SEO, some of this is more Etsy relevancy related.
Shop title/header - make sure it is full of key words that say what you sell and utilise all the available space. Think like a buyer, what words would they use to find items in your shop. Is the current text specific enough for what you sell? 'and' is superfluous and won't help in a search. All the other words except jewelery possibly aren't specific enough. What is your USP, your particular style or specialism?
Shop announcement - fill the first line of text with key words, a list is fine, ie the most searchable key words that say what you sell. After that you can add anything else you like, just make sure it's in a completely new paragraph separate from the first line. Both your shop title and announcement are very important for SEO. You can play around with it in Google preview to see what words fit into the available space the best.
Shop sections - use all 10, each section is a new page on Etsy, a new url and a new potential landing page from search engines. Add further key words to existing sections e.g. add stamped to pendants or as appropriate.
List more items - the magic number is meant to be around 100. The more items you have the most listings to be searched on Etsy, the more urls you have the more pages to be indexed by search engines.
Location - nothing to do with relevancy or SEO as such but this isn't in the correct format and most likely means you won't appear in local searches. Go to Public Profile, delete the current text, start typing in your home town/city, select the appropriate given, save it. US locations appear like this New York, New York, United States.
Titles - e.g. this -
http://www.etsy.com/listing/89305036/whimsical-bird-pendant-in-recycled-finehttp://www.etsy.com/listing/89305036/whimsical-bird-pendant-in-recycled-fineMake sure for both relevancy and SEO that your most important key words are at the beginning of the text and ideally fit into the url. Again think like a buyer, what words would they use to find this item. Titles do not need to be nice flowing sentences just a list of the best ordered words that describe the piece. Make sure you have enough key words in your title to fill both the url and the Google listing space - see any listing in Google Preview in edit mode. You don't need to include any punctuation as Etsy and Google ignore it plus it can interfere on occasion in searches. A possible suggestion on rearranging the text - fine silver bird pendant necklace ball chain whimsical. Is this type of silver class as recycled?
Descriptions - make sure the first line is always text from your titles, not necessarily in the same order but the most important words first, a sentence is good. Use paragraphs and/or bullets so the text is easier to read. You need to explain in words everything about the item as if the buyer can't see it. What is it, how big is it (metric and imperial), what colour is it, how many do you get, what is it made of, how does it feel, who might like it, what can you do with it, what inspired you, add care instructions and so on. If an item is made to order state the process and timeline etc. As all description text is potentially searchable by Google you can add lots of information. At the end add links to other items/sections/policies in your shop. All of this is good for SEO.
Tags - you need to use all available tags space which you haven't yet, you also should be using 2-3 word phrases based primarily on the text in your titles. Tags are to say what the item is and not for potential uses. Take out spring jewelry and cool mom gifts as they are suggested uses and are not allowed. Take out your shop name unless you know people will search for you this way as you can be found via Shop and People searches. Unless you are really stuck on what to include in tags avoid using more than one team tag per listing ie use as many tags as you can to describe your items. So you tags should be things like silver bird necklace, ball chain necklace, silver bird pendant, bird jewellery, bird jewelry and so on. Necklace isn't in there at all at the moment.
Profile - consider adding key words at the beginning before the text that is currently in there. The reason being that profile pages are heavily indexed, or at least seem to be on Google, and are a platform into your shop. It could help searchability by adding the same kind of information in the first line of your shop announcement here too.
Marketing - how are you marketing yourself? This is key on Etsy, you sell yourself, not the site. There are lots of ideas etc on the blog link below.
