Promoted Listings - How do you choose?

[tori_729]

I just realized that I've been using more than my $30 per quarter TRS credit for Promoted Listings. Whoops! I was paying WAYY more than I realized in ad fees! So I've gone through my listings and changed my percentages some. My question is - which items does it make sense to make promoted? Should I promote them all at very small percentages or just some?

Lately, I've been basing it on the number of other similar items for sale but I sell a lot of replacement parts which I would think might come up in Google searches so I would want to promote those. I've been going back and forth on what/how much to promote.

I think everyone has to figure it out for HIS/HER items....... what works on vases,  probably not good for a washer belt. 

To me, it makes more sense to promote the more expensive stuff or things with a wider margin.........say you are using 3%....on a $10 item.....the fee is only 30c, but how much do you make.....%.5.,6.  on a $50 item, you would pay $1.50 fee (taking ONLY about promotional fees), but you would take home $?.........$40+.....depending on your costs.
