Not sure why this isn’t common knowledge but you can set the maximum and minimum prices of the items that show up in your Auction Ads.
For instance I sell a fair few phones and use Auction Ads to monetize a very small amount of spare traffic that isn’t suitable for my normal affiliate programs. In the past a keyword search for phone brought up loads of cheap phone chargers and phone covers but if you set the minimum bid to $50 it gets rid of these items and increases your commission.
The way eBay works is that the bids increase near the end of the auction so if you can send somebody to an auction that’s about to end you will get impulse purchases.
Here is the code:
auctionads_ad_kw = "keyword minprice:50";
Replace minprice with maxprice to set the maximum price.
Did everybody else know this already?
