Rank Tracker is the most powerful and effective way to track the results of syndication on your site's rankings, but you can also run a quick check yourself to get an idea of how broadly your Article Samurai submissions are being picked up.  This uses a technique we call "fingerprinting", and you can do it almost anywhere.

The idea is simply to select a stretch of un-spun text from your original article - one which you can be sure appears the same in each version.  Ideally this should be more than a few words but less than a few sentences.  Now search for that text, in quotation marks, on Google.

If it's a long enough stretch of text, it's unlikely to show up in too many other places, so each hit should be to a variation of your article.  (if necessary it may help to add the author name after the quoted fragment of your article to the search query)

In this way you can find out not just how much your article is getting around, but how many times Google is picking up distinct versions of it.

This can serve as an easy ad-hoc method of keeping tabs on syndication efforts, and a handy way to double-check Rank Tracker's results if you are not seeing what you expected to see.
