Dazed and Confused!

Well, at least confused anyway.  I mentioned in my last post that my site had climbed up to #83 in the Google listing.  When last I checked, I had fallen all the way back to #114.  Now, I understand that the ranking will fluctuate but I am surprised and confused by such a large drop.  I would have expected to maintain or slightly improve my ranking as the on and off page SEO I had done gets indexed over time.  I see I still have a lot to learn about SEO and niche marketing.
