I was at DigitalPoint today, and came across a great thread “Adwords and ebay?How necessary?“. I personally don’t like to use AdWords (I prefer Yahoo’s YSM), but I wanted to get some basic tips for PPC in general… since I’m always wanting to learn how others are doing it.
Anyway, manx posted the following post, which I thought was extremely useful. I wanted to put in here, so I could easily reference it in the future… but some of you might find it useful as well. It’s basic, but the basics get easily lost when you dive into PPC.

I’ve been seeing a lot of complaining, specifically on the EPN forum about impressions and clicks not tracking. Lots of whining and basically ill feelings directed towards eBay’s programmers. Being a programmer, I feel for them. I do however agree with some of the issues, specifically the lack of validation of input fields. This lack of validation is allowing users to input incorrect data for their widgets. Though, I feel for the people that are missing clicks and impressions because of this… I have to say, “Why don’t you inspect your links after you’ve built them?????” It’s really easy to double check your work and verify that it looks correct.
