Bookmarking and directory submissions are crappy/spammy links in Googles eyes. If you did a lot of them too fast you might have been penalized. I would disavow those links.
Extend the registration of your domain Write more content Promote your website on Social Media Speed-up your website
Check all the On Page factors, Site speed, internal links, Broken links etc. and try to find out the reason.
I would not worry about it. It could be a sign of good things to come. Just keep on posting good quality content and getting good quality backlinks and you will be back up there stronger than before.
Google dropped your website because it give not any benefit to users. For example, Google place your site for some time on top pages. He realized that People not stay on your website or not re-visit your website. According to this analytic, Google drops your SERP ranking. So, new ranking according to your new analytic.
May Your site have been hit by Google panda update which happened on 22nd january'13.But do not feel bad.Do the blog comment,Blog post, article and start SMO for your site again But remember make your work unique.
be careful with directory submission and social bookmarking which pointing direct to your site ... it's can harm your site. i think you must create more backlink diversity. Google’s latest “zoo†updates have changed a lot of things that used to work in the SEO world, but few things have changed as much as the standard practices of building backlinks and most of the websites that got hit with the link diversity penalty had more than 50% of their backlink anchor texts using some form of “commercial†keyword
