(1) Browse to Traffic Sources > Search Engines.
(2) Click "paid" (in the middle of the page, it's sort-of hiding above the Site Usage tab).
(3) Click [Add to Dashboard] right underneath the "Search Engines" headline.
Now you'll find that there's a new report, "Search Engines" on your dashboard (the first page you see once you log into your profile) that shows you just the paid search results. You can also drag-and-drop that report box around your dashboard to move it higher up the page.
Does that help?
I will be more clear of my problem.
Actually, my site has a form and when the user clicks the button, the user will be directed to another website.
I want to track how many users coming from adwords clicked on this button. I have implemented outbound link tracking using Google Analytics but again it will track all the traffic, i want to identify the traffic from adwords.
Hope it is clear to you.
Hmm...The ideal scenario is that, when your form is submitted, it causes a "success" page on your own domain to be loaded. Note that it would have to be on your own domain, not the domain of the external site to which you are sending the traffic.
Once this is in place, you can start looking that page up by going to, for example, Content > Content Drilldown, plug in the page's filename in the Find URL textbox at the bottom of the page, then click it. Once you're at the success page's "Content detail" page, click the Analyze dropdown menu, then click "Entrance Sources". Hopefully Google AdWords or "google / CPC" shows up in that report, and then you know how many AdWords visitors clicked your form button for the timeframe specified.
The real devil in the details is getting that success page to load. Unfortunately, I don't have the time (I barely have the expertise [;-)]) to get into that subject, but the idea is that, when the form is submitted, it uses some JavaScript to call your success page in addition to the form's destination page (your success page has the Analytics code in it, of course). The success page can be in a hidden Iframe or just a regular pop-up; the important thing is that the page needs to be called so that Analytics has a record of it.
Hopefully that's enough to get you going. Maybe someone else here might be willing to post some demo JavaScript for this?
