Hi all... I've put together a review site for amazon products (cloaked aff links). Content is all original, unique, and legible. I target low-comp review keywords and the site is about 150 products big so far. Backlinking has been all white-hat via web 2.0 articles and EZA submisisons (again, all unique and legible). Site only has about 150 backlinks (most do-follow) from my efforts to date. Site is about a month or so old. The first week was slow. After about 3 weeks, I had several dozen top-20 rankings and many top-10. Suddenly, on the 8th of January, all of my rankings for all keywords dropped into the hundreds. The only thing Webmaster tools indicates is that, as of around the 2nd week of January, it takes approximately 13 seconds (on average) to open a page on my site. This is clearly not accurate as I gzip everything and everything is cached. I've even tested response from multiple browsers/machines. Although this seems to coincide with the date when my rankings tanked, can this alone be the cause for my rankings drop or is it just the sandbox at work? Any ideas?
