Hi Michael,
1) regarding a keyword search on Google. If you are searching for a single keyword in Google, its quite possible that you will move around in the search. However, if you are trying to be relevant for a specific phrase you **should** stay within a page or 2.
Case in point -
I'm running a Christmas in July sale right now and one of my items that usually ranks around the 3rd page of a google search is my 'Boutique Magical yarn'
https://www.etsy.com/listing/79609593/cij-sale-20off-boutique-magical-yarn-inHowever, right now its at the top of page 2 in the google search for "boutique magical yarn"
http://www.google.com/#q=boutique+magical+yarn&hl=en&prmd=imvns&ei=0nH-T8unJ-SI2gWe1bTEBA&start=10&s...If I want it to appear on Page 1 of the search I'd have to have the exact phrase "Red Heart Boutique Magical Yarn" in the title and try fighting it out with Amazon, and the Big box shops that sell the same item.
When google shows items as a result of a search, it looks at the item title and the first few lines of the description. (you can see exactly how much of the description when you are editing your listing).
Google seems to rank items with the searched phrase that's in the title and in the beginning of the description a little higher than items that don't have those keywords in the beginning of the description.
So if your shop title of
""Vintage Bus Scrolls, Tram Rolls & Subway Signs "" is part of your item title, then by all means include it as the first line of your description.
I tend to use the key phrases from my item title in the first part of my description though as having my shop title of
""affordable yarns, soap dishes, mannequins, wearable art "" in my description really won't help a buyer find my items.
I hope this makes sense.
