A lot of people will tell you that search ads are a waste of money. And I'd agree.
Although you get views from search ads, you want to get the RIGHT views, the people who are your target market, in order to get sales.
Otherwise, you are paying so much for 1 sale from the ads.
Search the forums for free advertising/promoting tips, there are MANY places that you can promote for free and start there.
And I do find my products on search engines, but that's because I spend time promoting OUTSIDE of etsy.
Good luck to you!
