I am looking for a way to track the number of times my web site is displayed on Google, Yahoo! and Microsoft Live. I look at this as ‘Free’ brand impressions that quantify the results of my SEO efforts. If someone has a better method I am open to it.

Please comment …

Some thoughts ..
In the CPC console I can view the number of impressions I received in aggregate, for this example we will say that number is 50,000.

Let’s assume the industry average for banner advertisements on vertically oriented properties is $20 / CPM.

Using these two values we can easily deduce the value-add of these impressions is $1,000.

This simple math works well when impressions are tracked as they are in AdWords. The piece of data that is not readily exposed by Google is How many times does my web site appear within the organic result set?
