I think before you begin your site’s optimization, you should read the optimization strategy, tips, and technique that become very helpful you. If you continue with your own style, Google may penalize your site and you well aware about Google Penalty. Still you have a time, less but effective will give you good result. I agree with neighbor dmbtransports, you must read Google panda and Page Rank policy. Keep in mind don’t violate Google rules and regulation. If you love Google then Google obviously love you.
