Mammamyst:
I'm not going to make the aim of this group to plug my SEO course, promise!
But you might have a read here:
http://twinklyspangle.blogspot.com/2011/01/twinklys-beginner-seo-day-4.htmlWhere I explain why links to your shop from relevant sources are important.
Basically, you can improve your keyword frequency and things as much as you like, but SEO isn't just based on that. What will boost you up the pages to those fun page 1 and 2 spots on Google, are backlinks.
So, if you can get your main Etsy shop page linked from a really popular craft blog, thats a much more relevant backlink than say, a football news page.
Your items couldn't be more relevant to your own Etsy shop.
Does this make sense?
