Hi all, Impression pixels are used to track the number of times a link or advertisement is served on your webpage. The number of impressions will tell you the number of times a user viewed your link and can help you optimize your traffic, ad placements, and commissions. We recommend serving at least one impression pixel per Campaign on every page that has eBay links. However, the best practice is to serve one impression pixel for every ad on every page.
Some tools already include an impression pixel. However, if you are using links created prior to May 1, 2009 with the Link Generator, RSS Feeds, Data Feeds, or API calls, you are probably not using an impression pixel.
If you are using one of these three tools, you should check to see if you are using impression pixels. To check if a page has an impression pixel, look for image tags like this:
<img style="text-decoration:none;border:0;padding:0;margin:0;" src="http://rover.ebay.com/roverimp/1/NumericRotationID/1?ff3=1&pub=YourPublisherID&toolid=NumericToolID&campid= YourCampaignID&customid=&mpt=[CACHEBUSTER]">
The important part is that the image tag's “src=” field starts with http://rover.ebay.com/roverimp/1/
If the image tag does not meet the above criteria, you should generate a new impression pixel with the wizard in the tools tab in the eBay Partner Network interface (log in and look for "Impression Pixel Generator" at the bottom right). More information on how to create an impression pixel.
