Usually my website fluctuates between #4 and #5. Well for the past week or so it shot up to #4 and remained there until maybe last night. Last night it dropped to #6 and now it's at #7. I see about 3-4 low quality sites on the front page that are NEVER there so I'm thinking it's all the after-effect of an algo. refresh. I built about 10-20 .EDU/.GOV contextual links lately and sent about 300 social bookmarks to them as tier2, plus ran the bookmarks through lindexed to get the posts indexed a few days ago. So I want to say it's a Google Dance, but usually during a dance I at least see the site "dancing" back and forth, my site's just shooting more and more downwards. Thoughts?
