How Do You Keep Track of Keyword Rankings?

[siteadmin]

When you do your keyword research, my bet is that you may have tens or hundreds of keywords to choose from. How do you keep track of it and monitor your rankings? A High Rankings Forum thread asks this question.

One member still uses the old-fashioned pen and paper tool. I've seen most people use an Excel spreadsheet, and one member at the forum suggests that.

Do you know of any current programs that monitor your rankings for keywords? I know there are some that used to take the Google Search API key, but unfortunately it's been over a year since that has been discontinued by Google.
