You know your list better than anyone else, and you know what your audience will respond to best. If there's a certain page on the SpeakerMatch website you would prefer to link to with your affiliate link, you can do it!
All you need to do is add "?u=" to the end of your affiliate link, with anything that would go after "http://www.speakermatch.com/". You can only send users on to other pages at speakermatch.com.
So, for example, if this is your affiliate link: http://www.speakermatch.com/ref382374.html
And you'd like to send someone straight to this page: http://www.speakermatch.com/job/52022517826/
You would format your link like this: http://www.speakermatch.com/ref382374.html?u=job/52022517826/
Note that you should not put a slash (/) right after the "?u=".
You can easily test this by clicking the link you make. There's now a screen that shows the referrer's name for a few seconds before sending the visitor to the final destination. If you see your name, you know the click has been tracked.
