SEO Update - Yahoo! - "We're baaaack"

Let's do a little recap: we're in the process of updating the pbapottery home page so that it appears on the first page of results on Yahoo! and Google for the search phrase "stoneware pottery" (a string that is now up to more than 1 million results on Google)

• The page started at position 17 within Yahoo!
• The page dropped to position 39 or so for no apparent reason within Yahoo! (prior to implementing changes)
• The page moved from 39 up to 12 after making modifications
• The page outright disappeared from Yahoo! about 3 days later (for a period of about a week-and-a-half)
• And the latest... the page has now reappeared and is back at position #12

When I inquired with Yahoo! regarding the inconsistency (Googles results have been far more consistent), I waited a little over a week to hear back... then I received a scripted reply... but the page magically reappeared in the index which is far more important than their communication with me.

So... we'll be getting back to it shortly in hopes of picking up that last couple of spots that will place on page 1 instead of page 2. Thanks for playing along. pba.
