I use the {Keyword} to track Google and Adcenter traffic, but when I use it with Yahoo Search Marketing, I get {Keyword} right back instead of the keyword.
I can see how this would work if I had a landing page redirect that would get the OVKEY from the URL and then appended it to the redirect URL as &sub=(Keyword)
Is there an easier way though? Like I said, with the other networks, it's just &sub={keyword} and I'm done.
For YSMs Tracking URLs you just match for OVRAW & OVKEY. Matches will be assigned to $matches[1].
Just use a simple link redirect script that you link to, match the keywords, and pass them along. And at some point in the future you can expand this to track more variables and pass only along some kind of identifier for your records, instead of your keywords.
