My biggest targeted keyword phrase is again on page 2 (#12) on Google...but about every five days it drops to page 5...then to page 2 again. I would prefer page 1 then 2 of course, but 3 then 5? These SERP's changes are confusing me...I hope if they settle it, it's in my favor.
A lot of people have been reporting yo-yo search results for their keywords. Just keep building links and working on your page content. Hopefully that will help you stabilize your SERPs.
