Google Search - Are You Logged In?

This was the most wasted hour I had today; from time to time I like checking back on old clients to see how they are doing with their desired keywords. Way before I did some SEO in Baltimore, I was leaving in New York. Over there I had a client that was pinging from #13 (page 2) to #8 for his key phrase. I managed to get him to #3 and it stayed on #4. Every time I that I checked it since then it moved from #4 to #8, but today it appeared #1. I was surprised. This client got tons of gurus after me that couldn’t help bringing it higher on the ranking scale- who was this genius that manged to do it?!?

I tried searching for anyone that stating that they are doing SEO to that client but I couldn’t find anything. Finally after an hour I notice that I was logged in… I didn’t know that I will get different search results(!) I thought that Google just keep tracking your behavior when you’re logged in. so I logged out and at that very second the ranking went down to #4.

Now that was a waste of time.
