Hello Friend, First of all you should start doing directory submissions and social bookmarking with social media to generate backlinks for your website. Thanks
To put it simply, make sure everything you do on page, and off, look totally natural. That's the way to win after Panda update, I know from experience.
I'm not a psychologist, but blaming Google for the decline in your rankings is not the solution. Google is in business to offer their customers the best possible online experience. If they deemed your site as ... less than quality, then its their obligation replace it with something better. The good news is that you have not been deindexed or sandboxed. Start thinking like Google: "How Can I Give My Customers The Best Online Experience?" As has been started, offer quality content!!! Update your site on a regular basis! Get quality links pointing to your site. And in time, Google will see your site as an asset, not a liability!
To get your keywords position good in search engines start with back link generations. You can go for Link building to get fast results or Directory submission and social media.
You have to say/write down your website name/URL so that experts can view your site and give you some suggestions.
